Hello all,
Just got my first android phone. I need to port a tiny C application I have to my phone. It worked when I compiled a static binary but now I'm trying to compile a dynamic one, but before that, I'm trying to run a native hello world on it but not having much luck. When I run it on the emulator, it prints "Hello world" and then segfaults after that. When I run it on the phone, it doesn't even get that far. It says link_image[1995] CANNOT LINK EXECUTABLE.
These are my test files
test.c
Code:
#include <stdio.h>
int main (int argc, char *argv[])
{
printf ("Hello world!\n");
return 0;
}
Makefile
Code:

Output (on the phone):

What am I doing wrong?
I've never been successful with dynamic executables using a plain Makefile. I've always had to use the JNI approach with an appropriate Android.mk configuration. To do this, make an empty directory for your project. Within this directory, make a dir called "jni" and cd to it and copy your "hello.c" source file there. Add an Andriod.mk file that looks like this:
Code:
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE := hello
LOCAL_SRC_FILES := hello.c
include $(BUILD_EXECUTABLE)
Then, with the ndk path set appropriately (ie, on my system):
Code:
export PATH=${PATH}:/usr/src/android-ndk-r4b/build/prebuilt/linux-x86/arm-eabi-4.4.0/bin/
just run the ndk-build script (again, modify to point to your ndk installation):
Code:
/usr/src/android-ndk-r4b/ndk-build
This will produce two additional directories in the dir above "jni": "obj" and "libs". In the libs/armeabi/ dir, you'll find your (non-stripped) executable.
Just curious, where'd you get the Makefile? It looks like it should work, but I can't really see where it is getting it's libc.so.
I got the Makefile from http://betelco.blogspot.com/2010/01/buildingdebugging-android-native-c.html
It's for Cygwin so I made a few changes. The last comment says I should link it against crtend_android.o to prevent the segfaults but that didn't work for me. Maybe I did something wrong. I'm not really a C programmer and the only experience I have is with writing extremely basic apps so, honestly, I don't know much about linking but I'm trying to let that not discourage me from trying. It usually takes me days to get something simple done but it feels great once I manage to get my app to work.
I'll try your approach in a few hours and post back.
Oh, and I thought I should mention my phone is running Froyo at the moment.
Since I'm completely new to writing code on the phone, I thought I should ask if it is a bad idea to push the app to the phone and run it directly or should I really be using the emulator instead (since I'm not an experienced programmer)? I've got a very old PC and the emulator is slow as hell on it so it'll be great if i can avoid that.
I visited that site and read over their comments and modified the makefile at the end to match my system (gentoo linux) and it works fine on my phone (HTC Inspire 4G). I didn't do the "make run" thing, but just "make" and then pushed it to my phone manually and ran it from an adb shell. Worked fine. I'm using the r4b plaform ndk so that might be something. I'll D/L the r5b ndk and check it out.
I tried what you suggested and it works perfectly. Thanks!

Any good idea would be appreciated !
Thx
Building AOSP for the Nexus 6!
I want to give thanks to @sykopompos and @GROGG88. This was pretty much a concerted effort between all of us!
Preface
This is to help you learn to build, for other developers to share knowledge, for you to ask questions, etc. The main focus is not the ROM but it is in post #2 if you want to check out out!
I built this guide do to lack of 100% clear / easy resources I could not find on the net. The Google AOSP page made it seem much more difficult than it needed to be.
The intent of this guide is to streamline the process of setting up for and building AOSP!
Feel free to ask any questions about the build process. Please do not ask questions about Ubuntu / Linux!
Check out some basic edits to source in Post #2
This guide assumes the following
Have Ubuntu 14.04 setup, fully operation, and up to date. Hard Machine or Virtual, makes no difference. Must meet the minimum specs for compiling. Info from Google HERE
Understand terminal command line entry as this is all command line processes.
You are not here to ask for help with Linux, only the Android build process!
If you want to try the ROM then I have the latest build of Lollipop in this thread HERE!
Lets Begin!
Add Java
Code:
sudo apt-get install openjdk-7-jdk
Add Build tools (Adds the required packages at the time of this posting)
Code:
sudo apt-get install git-core gnupg flex bison gperf build-essential \
zip curl zlib1g-dev gcc-multilib g++-multilib libc6-dev-i386 \
lib32ncurses5-dev x11proto-core-dev libx11-dev lib32z-dev ccache \
libgl1-mesa-dev libxml2-utils xsltproc unzip
Add Repo command (Syncs Google Repository with your local machine)
Code:
mkdir ~/bin && curl http://commondatastorage.googleapis.com/git-repo-downloads/repo > ~/bin/repo && chmod a+x ~/bin/repo
Add bin folder to path for repo command (After you do this close Terminal and re-open to institute changes (easy way))
Code:
sudo gedit .bashrc
export PATH=~/bin:$PATH <-(add to end of bashrc)
Identify Yourself to the Repo (One day you may make commits so think about that when choosing your info!)
Code:
git config --global user.email "[email protected]"
git config --global user.name "yourpreferredusername"
Sync Repo (Download source... Sit back and grab a pop and a sandwich...)
Code:
mkdir ~/AOSP
cd ~/AOSP
repo init -u https://android.googlesource.com/platform/manifest -b android-6.0.1_r10
repo sync
Note: I use AOSP as my directory name. You can use what you want. You could use "aosp" or "Source" or "android" or "whateveryoulike"
Set up ccache (this makes subsequent compiling much faster!)
First: Close then re-open the terminal so you are in the home root
Code:
sudo gedit .bashrc
export USE_CCACHE=1 <-Append that line to .bashrc then save and close
cd AOSP
prebuilts/misc/linux-x86/ccache/ccache -M 25G <-I use 25 gigs but you can change that value to any size you feel appropriate)
Install proprietary binaries (Needed for things like GPS and Bluetooth, they are not Open Source like Android) (Install proprietary binaries from here in the root of AOSP folder (or whatever you called yours))
Code:
[url]https://developers.google.com/android/nexus/drivers[/url]
Run envsetup.sh
Code:
source build/envsetup.sh
Choose Device
Code:
lunch
Build it!
Code:
make -j16 otapackage
Note: using -j16 means 16 worker threads. This is fine if you have 8 logical CPU's so you may need to adjust that to a smaller or larger number if you have more or less Logical CPU's. Example: I have an i7 K edition Haswell so I have 8 logical cores; so I build with -j16. If you have an i5 quad core CPU which is 4 logical cores then you may want to consider -j8 as the set number of worker threads. Oddly enough Google actually recommends 3 to 4 times the number of logical CPU's. When I do that I have nothing but build crashes. You may need to experiment to get the right blend of performance and stability during build!
Find it
Should be located here: /home/yourusername/AOSP/out/target/product/shamu
Congrats!
Your know among the elite enthusiast that can build from source! Pat yourself on the back!

Added ccache instructions
Listed changes for AOSP Browser to not F/C on settings
12/14/2014
Initial Release
Congrats on building but you need to make some edits to make the ROM more "useable"
Note: Attached is a complete diff from pure AOSP to the changes made / noted in this post.
With AOSP defaults you to
Reload the stock recovery on boot
Doesn't utilize all Google Location services (all the way?)
Browser settings crash
Cant Play Youtube or Netflix, etc.
The following is a list of code changes to negate all that. Ignore the Flo and Deb specific files mentioned in there as I also build for those devices too! This is sorta hard to read but once you get it the first time it will make sense. Feel free to ask questions on how to read! I have attached a copy of the "ota_from_target_files" as it is modified in this guide.

I am just still playing with it. I had it barely over 24hrs... So far I am crazy impressed with it!
That's the best news I've heard so far! After running tons of different roms I always end up coming back to cleanrom, and I use it on all of my touchwiz devices.

Nice! I ran Cleanrom on my nexus 7 and loved it. Thanks in advance. I'll be watching for it. It is an impressive device. Enjoy!

Well, congrats on the new device! I was window shopping them a week ago, and couldn't justify it yet. I'm sure you'll enjoy!
**edit**
Also, the patched source files in the Nexus 7 thread will work to a degree. I do have Shamu binaries added in, but some of the features I've added are device specific and have not been applied to Shamu. The last build I made for Shamu was on 11/23 and I decided not to continue with it.
Yes, I was window shopping too and could NOT resist!
They make it so tempting with these "Next" and "Edge" programs!

Wow amazing! I'm going to give this a try when I get home from work! Just two questions.. How to compile with another tool chain such as sabermod or linaro? And how to compile it with a different kernel?

I am not an expert by any means but you will need to change the make files that point to the tool chain. It should not be that hard.
Same for the kernel.

Thanks man! I'm sure between this and Google I'll be able to figure it out!
For your code changes in the tutorial for building AOSP for the Nexus 6. Are there multiple files I need to change the code in or is it a single .mk file or different extension? I haven't been able to locate a file with similar code. If you could just let me know which files that is all I am asking, I can figure out the rest I think!
If anyone knows what files need to be edited feel free to reply!
Xileforce said:

Click to expand...
Click to collapse
It depends. To compile with another (prebuilt) kernel, you can just overwrite the prebuilt kernel in.. I think it's in ./device/moto/shamu-kernel. (If you rename the kernel image to match the existing file, that's all you have to do.)
On the other hand, if you want to compile a new kernel while building the rest of AOSP, there are several changes that you'll have to make (even for the stock kernel.) Here's a link to a page that might get you started: http://nosemaj.org/howto-build-android-kitkat-nexus-5 (The instructions are for kitkat on a nexus5, but they should be good enough to give you an idea of what you need to do.)

There are multiple files. Most of them pertain to the Nexus 7 and can be skipped. The Repo Diff command can be hard to read but I will tty to break it down a little bit so you can understand how to read that file....

Yes, those instructions work well! I fought for a little bit to get the Nexus 7 kernel to compile with the 4.8 toolchain. As a result I had things setup to compile the kernel before the firmware and using the output as my prebuilt directory specified in the device-common.mk which should be 'device.mk' for shamu. I have scripts setup for the 3 devices I'm building for that take care of cleaning and building everything. I have since modified my scripts to run the 4.8 toolchain within the AOSP tree instead of an external 4.6 toolchain... It's basically outlined here:

AOSP PATCHES:
DOWNLOAD
(these are built into the firmware above)
**Patch/Build instruction**
Make sure your source tree is located in ~/AOSP
Clone kernel sources and checkout for devices using:
Code:
cd ~/AOSP
git clone https://android.googlesource.com/kernel/msm.git hh-kernel/kernel
git clone https://android.googlesource.com/kernel/msm.git flo-kernel/kernel
cd hh-kernel/kernel
git checkout 88fbc66
cd ../../flo-kernel/kernel
git checkout 154bef4
Download and copy my patches to ~/AOSP
Commit flo kernel changes if desired
Code:
cd ~/AOSP/flo-kernel/kernel
git commit -a
Enter a description, ctrl+x and then enter to commit.
You can now use the included scripts to build 1/3 devices:
Code:
$cd ~/AOSP
./build-hammerhead.sh
or
./build-flo.sh
or
./build-deb.sh
That's it!! Grab your custom firmware and FLASH!

It's turning it into a two step process, but the result is the same. As far as compiling with a different toolchain is concerned, I have yet to try. I shy away from many of the "optimizations" and really just target physical features that I feel are missing from stock AOSP.
Hahahaha! Your the man Dude!
We need DLMontage over here too. I hope he gets a Nex6.
You need to get one!
Thanks guys! I'll be giving the things you guys said a shot.. I'm sure I'll figure it out. This is my first try every compiling a rom,, so it should be interesting lol.. Though I'm sure it will be significantly easier after the first time.

Check out this script by @yuweng to auto(matically|magically) compile TWRP for your device!
Lately the TWRP Compiling guide, has been seeing a lot of newbies who were struggling with TWRP flags to ensure they compile a usable build. So without delay, here we go!
If no input has been suggested, assume true/false

I've done those stuff offline from your gist[emoji14]have seen this thread after that but maybe you like the way i showed the defines as it's setup the way you would do in your BoardConfig.mk.
Haven't done those flags i am not sure about myself, maybe @_that or @Dees_Troy can bring light to some of them.
Gesendet von meinem LG-H815 mit Tapatalk
This thread is a great idea.
Especially with the update to twrp 3.0 with new flags.
I've been lucky enough to be able to guess/puzzle out/grab from other device trees enough to build and use the recovery on my personal devices, but information like this is very helpful to have consolidated.
Thanks for sharing.

Yeah, I just didn't have enough time to beautify it. Will gradually do so.
TW_CUSTOM_THEME := /path/to/theme/
this one is used to replace the stocktheme with a different one (like material-play)
the theme will be directly in ramdisk
TW_INCLUDE_INJECTTWRP := true — adds ability to inject TWRP into some Samsung boot images for Samsung devices that have recovery as a second ramdisk in the boot image
the second flag is quotes by dees_troy!
TW_NEW_ION_HEAP
this has sonething to do with 3.10 kernels and a different naming in /include/linux/ion.h ... like a switch between old heap_mask and new heap_id_mask
Sent from my Xperia T using XDA Free mobile app
Nice initiative with this thread, this has been oh say 2 years too long in the making haha.
TARGET_RECOVERY_FORCE_PIXEL_FORMAT
Not sure but I would imagine it overrides what TWRP detects nor do I see the difference between it and TARGET_RECOVERY_PIXEL_FORMAT. The only possible varible right now is RGB_565. BGRA_8888, RGBA_8888 and RGBX_8888 are not yet implemented.
TW_INPUT_BLACKLIST
Black list input devices that interfere with touch. For multiple input devices the delimiter is \x0a. You would basically build a special TWRP with TWRP_EVENT_LOGGING := true. Put it on the device and read the more verbose log to see what inputs you want to blacklist.
EDIT: Ah here is a copy of the wording I had in one of my xda posts about the subject and the commit link https://github.com/omnirom/android_bootable_recovery/commit/5742a40b87dfdc26df3bd9fe94197ae414ece546
Usage:
TW_INPUT_BLACKLIST := accelerometer
TW_INPUT_BLACKLIST := "accelerometer\x0agyroscope"
This can be used to fix touch input on devices where an input
device is breaking touch processing in TWRP.
We are using new line chars to separate multiple devices and in
the make file you specify the new line character with \x0a which
is the hex code in ASCII for a new line.
The new line character might be a bit of a pain to use as a
delimeter, but it is highly unlikely that an OEM will ever name
an input device with a new line character in the name.

On a side note is there a link somewhere to fixing graphics issues induced in 3.0? I see a lot of talk about it but nothing substantial.

Not really. Slanty graphics can be fixed with linelength, but as such there's nothing on that front. You might wanna slap a recovery.log onto Dees_Troy at #twrp on webchat.freenode.net though.
Every version has new flags introduced & also flags deprecated...
TARGET_USES_LOGD => Source
TW_SCREEN_BLANK_ON_BOOT ( Deprecated on android-6.0 => Source, on some legacy devices, TWRP will not boot without this flag)
Dees_Troy said:
There are other build flags which you can locate by scanning the Android.mk files in the recovery source. Most of the other build flags are not often used and thus I won't document them all here.

Download the script & extract it to your HOME or if you are 100% sure that you have already setup a fully working Build Environment on Ubuntu or any other linux distro then remark these lines.

BBQLinux => Menu => Administration => BBQLinux Python Switcher => Python 2
BBQLinux => Menu => Administration => BBQLinux Java Switcher => OpenJDK 7
Start the script with below command
Code:
sh twrp
Menu 1
You can use either OmniROM or Cyanogenmod repo to build TWRP
Choose either to use TWRP branch android-5.1 or android-6.0. Typically, for legacy devices with ICS or JB doesn't support TTF so if TWRP android-6.0 doesn't boot then you'll have to use android-5.1 branch.
You can either choose to use Full-Source or Part-Source. Compiled out recovery.img will have exactly the same size & files on ramdisk.
Yes, Part-Source is only using 41 of the projects to build a fully working TWRP. Syncing in progress. After syncing, you can refer to ~/AIO-TWRP-Compiler/sync.log for any error
Typically, when you have already downloaded the base repo, re-syncing it will only take a few seconds
Menu 2
Copy either your boot or recovery.img to ~/AIO-TWRP-Compiler folder
Key-in your vendor name
Key-in your device name
This step is extracting the ro.product.device & ro.product.model from your device directly which is typically require for identification when flashing update.zip from your vendor
Credits to RD osm0sis, the script will auto download osm0sis's unpackbootimg for mkbootimg arguments required for repacking recovery.img . . . :good:
mkbootimg arguments will be display & auto updated to the BoardConfig.mk
Part of the original mkvendor.sh script is adapted for the extraction of boot or recovery.img which also does the git initialization. If the ramdisk can be unpack then the recovery.fstab will be copied to the device tree folder, if not then it will create a basic MTK recovery.fstab, boot.mk & also BOARD_CUSTOM_BOOTIMG_MK. If you're not building for MTK then remove that line from BoardConfig.mk
You will need to add/ remove TWRP flags accordingly & manual edit on the TARGET_CPU_VARIANT either cortex-a7 or cortex-a9 for older MTK, refer to your device spec. Possible values are cortex-a5, cortex-a7, cortex-a8, cortex-a9, cortex-a15, krait, scorpion. Use generic for devices that do not have a CPU similar to any of the supported cpu variants
You will need to manual edit on the recovery.fstab to suit your device or TWRP-ify the extracted stock recovery.fstab
Menu 3
omni.dependencies is only a warning, will continue to build when you choose OmniROM repo
Make 4.1 is only a warning, will continue to build
Java 1.7 is only a warning, will continue to build
When you have build earlier, subsequent build will only take few minutes bcos of CCACHE... :good:
Menu 4
Updated Menu 4 support for Others. Or you can use Flashify or Rashr or above Others to install compiled recovery.img to your device, do check if they are compatible or it will brick your recovery or worse, whole device !
Key-in your device recovery partition path. Above is typical for LG
Done, test TWRP on your device to make sure it is working properly if not then add or remove flags accordingly & use Menu 3 to build again
Menu 5
Choose either Option 1 or 2, Option 2 is recommended & it won't take long if you are using Part-Source.
Menu 6
The script will auto open up a new browser for you to register a new account on github
Your device tree on github
AIO-TWRP-Compiler
bash script itself is self-explanatory. Thanks to the OP, he has offer to take over the maintenance of this script so hit your Thanks button to him... :good: If you found any error/ bug or have any new ideas/ features for this script then pm the OP or do a git pull request... :good:
Above is the detail explanation on the script GUI front-end, here i'll explained what the script actually does.
Menu 1
This menu will create a local_manifest.xml to remove unwanted projects based on your selection. When select Full-Source, it will also create local_manifest.xml to remove existing recovery & replace it with TWRP based on your selection.
Code:
<?xml version="1.0" encoding="UTF-8"?>
<manifest>
<remove-project name="android_bootable_recovery" />
<project path="bootable/recovery" name="omnirom/android_bootable_recovery" revision="[COLOR="Blue"]android-6.0[/COLOR]" />
</manifest>
Part-Source
It is normal that OmniROM & CM will consistently add new projects to their repo when they introduce new features or functions to it. The beauty of this Part-Source is that even when projects grows, this script will grep -v only the needed projects for building TWRP on any base repo.
This Part-Source is the extreme minimal for building TWRP therefore some of the additional projects are needed when you use particular TWRP flags. As of today ( March 2016 ), it will build a fully working TWRP with only 44 projects on both OmniROM 4.4 & CM 11 base repo. In the future, Teamwin may also add a new feature or function then you will also need to add additional projects to it too or OP will update it based on your feedback. Refer to compile.log for details.

This script has been tested & it works on any base repo from OmniROM android-4.4, 5.0, 5.1 & 6.0 & Cyanogenmod cm-11.0, cm-12.0, cm12.1 & cm13.0 using Full-Source or Part-Source but why use Full-Source to build TWRP when Part-Source works, most importantly, you are not building OmniROM or Cyanogenmod but TWRP.... Using android-4.4/ cm-11.0 base repo has its advantage, compiled TWRP size will be smaller & it can build all version.
If you use android-6.0/ cm-13.0 then obviously you can only build TWRP android-6.0 only, just edit the line 62, 63 for OmniROM or 72, 73 for CM accordingly. Building TWRP android-4.4 on cm-13.0 or on OmniROM android-6.0 will result in a build error ! Later base repo won't build TWRP older version !
Many newbies doesn't know that OmniROM/ CM repo are incremental updates & they create a separate cm11, cm12, cm12.1, cm13 each & sync individually to each of these folders.
Above syncing cm-13.0 & as you can see, it is also using source from cm-10.1, 10.2 & 11. Syncing all to the same ~/omni or ~/cm folder will do.
Sometimes on certain devices, OmniROM android-4.4 or Cyanogenmod cm-11.0 base repo just won't boot then you can try by editing this line to android-5.0 or cm-12.0 & updating it will only take a very short time if you use Part-Source.

Device tree
This script will create a barebone minimal device tree for building TWRP. Anything less will result in a build error. It will create five files which is just sufficient to build a fully working TWRP using prebuilt kernel. It will build kernels too, just update the correct kernel config to BoardConfig.mk & remove the remark # needed projects for building kernels. However, i don't see the needs to build the same kernel with every TWRP new build, it will take a longer time to build, most importantly, you are not building a ROM.

My TWRP-ify recovery.fstab. Typically, for ext4 partition, you don't need to specify flags=display= & backup=1, it will be taken care of by TWRP, for more info regarding fstab flags then refer to Main Thread for *RECOVERY.FSTAB*... :good:
RD osm0sis's unpackbootimg is able to extract --second <2ndbootloader-filename> & also --second_offset <address>
The repack arguments will be auto-updated to the BoardConfig.mk Thanks to RD osm0sis. Some TWRP flags ref taken from here... :good:
osm0sis's unpackbootimg also support --dt <filename> :good:
Some devices require additional info for factory update.zip then add it accordingly to the device tree, typically is your device_(device-name).mk. Look at other device tree here & here & here for reference. On CM base repo, you can also use mkvendor.sh... :good: However, you will need to manually edit certain files as no DEV has been updating it, currently it will result in a build error even when using Full-Source !
Do take note that even an extra space on some of the lines at BoardConfig.mk will result in a build error !
Menu 3
Below are the commands to build TWRP, thats it !
Code:
cd ~/omni
[COLOR="blue"]OR[/COLOR]
cd ~/cm
prebuilts/misc/linux-x86/ccache/ccache -M 25G
export USE_CCACHE=1
export LC_ALL=C
source build/envsetup.sh
lunch [COLOR="blue"]omni[/COLOR]_S939-eng [COLOR="blue"]<= S939 is the device name[/COLOR]
[COLOR="Blue"]OR[/COLOR]
lunch [COLOR="blue"]cm[/COLOR]_S939-eng
make -j4 recoveryimage
Menu 4
Below command generically will work on most Android devices. Updates : Has updated this menu to support this, just key-in /path-to-your-device-recovery-partition
Code:
adb push [COLOR="blue"]$OUT[/COLOR]/recovery.img /data/local/tmp
adb shell su -c "dd if=/data/local/tmp/recovery.img of=/[COLOR="blue"]path-to-your-device-recovery-partition[/COLOR]"
To use the $OUT path, you must first source it then lunch your device name, refer to previous Menu 3 for info.
Menu 5
Option 1 is make clean
Option 2 is wipe the whole repo base folder except the hidden .repo folder. As mention on the script GUI front-end, after that, use Menu 1 will have all the files extracted out.
Menu 6
This menu is using curl to create github repo.
It is for you to publish your device tree either for diagnostic & debugging when you ask for help. It is also for you to share a working build so that others can refer to it when they make a build of their own or git clone yours & build it themselves.
Preface & Credits
Many newbies make mistake by using other DEV's device tree which is normally meant for building ROMs, using it to build TWRP therefore will result in alot of build errors !
Above script can also be use to build TWRP for any Android devices that uses standard Android header, except for Menu 4 which is specifically for MTK devices only. Just edit the script to add support for your device... :good: Updated support for other devices
This project was actually started way back at 2013 & this is the main reason why TWRP doesn't build is bcos of the tedious, confusing & wrong Build Environment setup, it is all so different on so many different linux distros & OSes version, i went on to developed Easy Magic TWRP.... Now i use Intel device & this script did build a working TWRP for it too.... :laugh:
That's why i strongly recommends BBQLinux for beginners, Thanks to RD codeworkx, i can guarantee that any Build Error is not cause by wrong BE setup as its already built-in on BBQLinux... :good:
The other reason TWRP doesn't boot is bcos of wrong mkbootimg repack arguments, Thanks to RD osm0sis for his awesome unpackbootimg... :good:
Since many newbies are having problems with building TWRP & flooding the TWRP thread here

Which is actually meant for intermediate users, i've offered to share this script when OP decided to open up a new thread here for TWRP flags.... :good:
Credits Updates
Hacker432 for testing & feedbacks on this script, now it uses the ATC folder so that it'll support other languages other than English & TWRP will boot now when build on cm-12.1 base repo... :good:

My TWRP doesn't boot
Try unpack/ repack your stock 3e recovery.img with AIK, push it to your device & if it doesn't boot then obviously your device is not using standard Android header & so does this script will not build a bootable TWRP. Try google your device info on how they did it, Eg. Sony devices uses BOARD_CUSTOM_BOOTIMG_MK for repacking boot & recovery.img & update it accordingly to your BoardConfig.mk
Code:
adb shell cat /proc/last_kmsg
[COLOR="Blue"]OR[/COLOR]

Extreme minimal, TWRP require this only one flag TW_THEME := to build or it will error out. You will also need other flags as well, refer to the OP. Some devices won't boot when certain TWRP flag is used or not used bcos its not compatible with your device kernel ! Most legacy device doesn't support TTF & TWRP won't boot so you have to build with TWRP android-5.1 with TW_DISABLE_TTF := true flag
Code:
[URL="https://github.com/TeamWin/android_device_kazam_thunder_q45/blob/cm-10.2/BoardConfig.mk#l49"]TW_NO_EXFAT := true[/URL] [COLOR="Red"]<= To disable exfat[/COLOR]

Above are some of the flags that can cause TWRP not to boot up. If you are using Part-Source then you need to add additional projects to support these flags as most of them are disabled on the script. Just remove the remarks # from the script for that particular projects. More detail info refer to above post #11 Part-Source.
Refer to the most bottom Bug Report on how to obtain recovery.log, without it nobody is able to help you.
Code:

TARGET_RECOVERY_PIXEL_FORMAT := RGBX_8888
TARGET_RECOVERY_PIXEL_FORMAT := BGRA_8888
The other reason it doesn't boot is that it actually does boot up but the screen is blank ! Try adb shell & it should work on this scenario.
Try different pixel format one at a time, one of them should work.
Code:
[URL="https://github.com/omnirom/android_bootable_recovery/blob/android-6.0/minuitwrp/Android.mk#l114-l116"]TARGET_RECOVERY_FORCE_PIXEL_FORMAT := RGB_565[/URL]

[URL="https://gerrit.omnirom.org/#/c/13948/"]TW_DISABLE_DOUBLE_BUFFERING := true[/URL]
When not setting any pixel format, the default is RGB565 & it should work on most Android devices. You can also try the above when non of them works.
Code:

If your existing device tree uses this & all the above doesn't work then drop by at TWRP IRC channel to get further help.

Miscellaneous Tips
As mentioned many times, most of the time build error is bcos of wrong BE setup, use BBQLinux & you'll get over it. If you have already build on other distro then refer to here on how to use this script or migrate the source code .repo to BBQLinux.

TWRP has everything specified to standard Android path unless when it doesn't work then you'll need to find that out yourself. Do take note that some device doesn't support certain feature such as CPU temperature, battery level, mount USB storage & etc then refer to the OP for flags to disable it.
Code:
adb shell su -c "ls -R" > [COLOR="Blue"]myAndroid.txt[/COLOR]
Above command will list out everything on your device.
Code:
adb shell su -c cat /sys/class/power_supply/battery/capacity
[COLOR="blue"]88[/COLOR]
Eg. Say the battery capacity doesn't work then look for that path at myAndroid.txt for something that says battery/capacity & specify it at BoardConfig.mk
Code:
adb shell cat /sys/class/thermal/thermal_zone0/temp
[COLOR="Blue"]27516[/COLOR]
If CPU temperature doesn't work then look for thermal/temp
Code:
adb shell
su
echo 0 > /sys/devices/platform/i2c-gpio.24/i2c-24/24-002c/backlight/lcd-backlight/brightness
echo 255 > /sys/devices/platform/i2c-gpio.24/i2c-24/24-002c/backlight/lcd-backlight/brightness
If brightness doesn't work, look for lcd-backlight/brightness, Eg. above command should be able to change the level of brightness if that is the correct path as indicated at myAndroid.txt.
Sync corruption
git & repo is like a Super Intelligent Source Code Auto-Resume Downloader when working together . . . :good:
You can stop it at any time, restart it back & it will auto-resume. cm repo & source code is located at ~/cm/.repo, omni at ~/omni/.repo it is a hidden folder & to view hidden folder via File Manager, you need to press Ctrl + h
Sometimes you have corruption then repo sync wouldn't work & normally you just need to delete manifests, manifests.git, manifests.xml with a repo init & repo sync then you'll be back to normal.
If still this doesn't solve the problem then delete everything EXCEPT the folder project-objects & projects, both of this is the actual source code folder.
After this a repo init then repo sync & everything will be back to normal, i guarantee, done this many times, no worries . . . :laugh:
Sometimes when you have severe data corruption, above technique will not work then manually cd ~/cm or ~/omni then repo init then repo sync & see what repo & git has to say then follow the on-screen instructions to remove the corrupted projects.
Scroll back up & see what the error was, remove the corrupted project then repo sync. In this case is rm -rf ~/cm/.repo/projects/prebuilts/clang/linux-x86/host/3.5.git
Subsequent sync show above error. rm -rf ~/cm/.repo/project-objects/CyanogenMod/android_external_icu.git
rm -rf ~/cm/.repo/projects/external/jemalloc.git
rm -rf ~/cm/.repo/projects/system/extras/su.git
rm -rf ~/cm/.repo/projects/external/libcxx.git
rm -rf ~/cm/.repo/projects/external/libcxxabi.git
rm -rf ~/cm/.repo/projects/external/libunwind.git
rm -rf ~/cm/.repo/project-objects/CyanogenMod/android_external_busybox.git
And finally all corrupted projects has been removed, subsequent repo sync & all files will be auto-extracted out.
Corrupted .repo folder
i've make a back up of my .repo folder using tar.gz compression years ago & when extracting out, normally will end with data corruptions except if you use lrzip... :good: You will need to manually remove all the text files such as hooks, pre-auto-gc & commit-msg which is supposed to be a symlink files.
After you force overwrite extraction, a repo init & repo sync will end with above message.
You will need to manually delete all the hooks.txt file found at .repo folder
You will need to manually delete all the commit-msg.txt file
You will need to manually delete all the pre-auto-gc.txt file. You might need to repo sync --force-sync many times to overwrite all the corrupted projects & after that, you won't be getting any of these error messages again.
Syncing work tree error - Doesn't check out all files
This operation must be run in a work tree
Run the below command will give you hint
Code:
repo --trace sync -l
Above hints the corrupted projects so remove it => rm -rf /home/yuweng/cm/.repo/projects/frameworks/ex.git
repo sync still it doesn't extract out all the files so you need to run repo --trace sync -l again. Delete the hinted project => rm -rf /home/yuweng/cm/.repo/projects/frameworks/webview.git
When all error has been fixed, a repo sync & all the files will be extracted out correctly

TWRP FAQ
@yuweng the script has really been thought over for a long time and you also have put in tons of work in it. Thanks for it man!
Thanks bro... :highfive: The script initially includes BE setup for Ubuntu that includes setting up of Python, Java, Make, Git, build packages, adb rules & etc, now its half the size bcos we don't need to do all that on BBQLinux... It has went thru alot of revision, i lost track, one has PhilZ Touch on it, one revision will detect the device info such as graphics resolution, emmc or /data/media device & etc, you can actually do wonders with adb shell, automated alot of stuff for BoardConfig.mk, all in all, this script has about 4 years of work in it...

4 YEARS!!!! @Dees_Troy, @bigbiff, @_that this guy deserves a medal! And about the BE Setup, my good friend @thewisenerd had made an Android compiler which included a rather fancy dependencies check in a python program. I'll include it into AIO-TWRP-COMPILER as soon as I finish my school work for the week
Haha, they are all my Master Shifu's & they all have more experience than me on TWRP... :laugh: You are most welcome to add-in new features to it... :good:

Experience?? They're encyclopedias on TWRP. But it's worthless if every humbug on the planet wants to compile it and doesn't even know what "ls -R " is supposed to do You're being a great help to everyone. I'll try and get them to try this when I can make it compatible for people who have already downloaded the source
Actually its quite easy but then again any wrong BE setup will result in build error that's why i strongly recommends BBQLinux for starters, its as easy as Ubuntu to setup, i can guarantee many will like the UI, Thanks to RD codeworkx.... :good:
Code:
mkdir ~/omni

Remark or delete these lines & it'll work...
Updates - Migrating source code .repo to BBQLinux
So far my experience is that only lrzip is able to compress & extract source code .repo folder without data corruption... :good: Just open Ubuntu Nautilus File Manager & delete everything on your cm or omnirom except the hidden folder .repo
This hidden .repo folder is where the actual source code are, zipping it will be enough for migration, a repo init & repo sync will have all the files extracted out on BBQLinux ...
Code:
sudo apt-get install lrzip
cd /path-to-your-existing-[COLOR="Blue"]omnirom[/COLOR]-or-[COLOR="blue"]cm[/COLOR]-folder

AIO TWRP Compiler wiki
@yuweng, I have started writing down the wiki for this script at the Github repository. Would be grateful if you started writing the things you have mentioned here in that as well, and I'll proof-read it later on and also keep writing things myself
Below are some guides on how to build your very own ROMs and Kernels for the Samsung Galaxy Note Edge gsm versions.
XDA is a great community that has taught me so much that I want to share what little I know with you, so you may also build roms and kernels on your own. As a long time follower of XDA, last year I decided to gen an account so I could start contributing and also so I could start thanking people for thier great work.
I started out on the Motorola Flipside, and quickly moved on to the Samsung Captivate Glide, where guys like @bubor and @steadfasterX were not only doing great work, but were willing to share thier knowledge. By God's grace, I made some roms and kernels for the Samsung Galaxy S4, and now for the Note Edge.
All of my work can also be seen in more detail at https://thealaskalinuxuser.wordpress.com/
These guides are specifically built for the Note Edge, but in principle are applicable in any phone/rom/kernel.
In this guide, I am using Ubuntu 14.04. You can use virtual box, virtual machine, or any other method, but I used it installed on the computer.

Step by step instructions for building AOKP 6.0 for the international variant of the Samsung Galaxy Note Edge
This is adapted from my previous writeup on building AOKP 6.0 for the T-Mobile variant of the Samsung Galaxy S4:
http://forum.xda-developers.com/gal...uide-step-step-instructions-building-t3402637
I have noticed that the build instructions on the AOKP website are a bit outdated. They date back to JellyBean. I would like to encourage other users to build more custom roms, and I thought that it would help if I show how to build one of the roms wich compiled successfully for me (Praise God!). It is my hope that these instructions are clear and easy to follow. Hey, if I can do it, anybody can do it!
<<<<< Step 1: Setup your system. >>>>>
To be honest, this can be the most daunting part, because if you do not set this up properly, it just will not work. I use Ubuntu 14.04 on a HP Compaq 6715b laptop. I know, not a very ideal compiler, but it is what I've got. Here are the suggested packages, just open a terminal and paste this in:
Code:
$ sudo apt-get install bison build-essential bzip2 curl dpkg-dev flex g++-multilib git git-review gnupg gperf lib32ncurses5-dev lib32readline-gplv2-dev lib32z1-dev openjdk-7-jdk libbz2-1.0 libbz2-dev libc6-dev libghc-bzlib-dev libgl1-mesa-dev libgl1-mesa-glx:i386 libncurses5-dev libreadline6-dev libreadline6-dev:i386 libx11-dev:i386 libxml2-utils lzop maven pngcrush pngquant python-markdown schedtool squashfs-tools tofrodos x11proto-core-dev xsltproc zip zlib1g-dev zlib1g-dev:i386
This will take a while. Once it is done, do this:
Code:
$ mkdir ~/bin && curl http://commondatastorage.googleapis.com/git-repo-downloads/repo > ~/bin/repo && chmod a+x ~/bin/repo
$ gedit ~/.bashrc
Now you should see gedit open up your .bashrc file, to which you should add this at the very end, and save it:
Code:
export PATH=~/bin:$PATH
Now you need to close your terminal and open a new one to get the PATH variables to stick. Actually, it wouldn't hurt to reboot your system after installing all of those programs we just installed. Your computer should now be primed and ready to go.
<<<<< Step 2: Download the source. >>>>>
Here is a very short project for you that takes the computer a long time to complete. Open a terminal and start typing:
Code:
$ cd ~
$ mkdir aokp6
$ cd aokp6
$ repo init -u https://github.com/AOKP/platform_manifest.git -b mm
$ repo sync
You can now go outside, play with the kids, phone a friend, and then go to bed. When you awake the next morning, this might be done, depending on your internet connection!
<<<<< Step 3: Adding the device, kernel, and vendor trees. >>>>>
In some cases, you can simply type the command
Code:
$ breakfast
and just choose your device, but at this time, the AOKP repository did not include a current device tree for the TBLTEXX phone, so we need to download one. Later, perhaps we can learn about adding them as dependencies or in your manifests, but for now, here are the links to download them, which will help you understand how this works, follow the link, and click the download button to download the zips. Yes some of these are from AOKP for other files you need. Be sure to grap the MM branch for this guide. There are now newer Nougat branches, which works the same as well, but this guide was written from MM.
https://github.com/alaskalinuxuser/device_samsung_tbltexx
https://github.com/alaskalinuxuser/kernel_samsung_tblte
https://github.com/alaskalinuxuser/device_samsung_tblte-common
https://github.com/alaskalinuxuser/device_samsung_qcom-common
https://github.com/AOKP/device_qcom_common
https://github.com/alaskalinuxuser/tblte_vendor_samsung
Once you have downloaded them, unzip each one and rename them:
aokp_device_samsung_tbltexx --> "tbltexx" (Place in aokp/device/samsung/ )
aokp_device_samsung_tblte-common --> "tblte-common" (Place in aokp/device/samsung/ )
aokp_device_samsung_qcom-common --> "qcom-common" (Place in aokp/device/samsung/ )
device_qcom_common --> "common" (Place in aokp/device/qcom/ )
tblte_vendor_samsung --> "samsung" (Place in aokp/device/samsung/ )
kernel_samsung_tblte --> "tblte" (Place in aokp/kernel/samsung/ )
You may have to make the folders that they go into.
Now you should probably take a break before going on to the next step!
<<<<< Step 4: Editing the device, kernel, and vendor trees. >>>>>
Now, go to the device/samsung/tblte-common folder and make any edits you want. It should work just the way that it is currently. This is where you could add apps, change features of your phone, etc. See the following posts for guides on doing that.
Note: Because repositories are constantly updated, I can only garuntee that this will work based on the files as they were the day of this writing. However, with all of this in place, if you follow this guide, it should work realatively the same as it did for me.
Now that all of the hard work is done, it is time to actually build something!
<<<<< Step 5: Start your build! >>>>>
Phew! You have invested a lot of hours into this project, now it is time to actually put those files and time to use! Open up a terminal in your aokp6 folder and start typing:
Code:
$ . build/envsetup.sh
Which will output something like this:
Code:
including vendor/aokp/vendorsetup.sh
including sdk/bash_completion/adb.bash
including vendor/aokp/bash_completion/git.bash
including vendor/aokp/bash_completion/repo.bash
Now type:
Code:
$ brunch tbltexx
Which will start the long build process, it will output this:
Code:
including vendor/aokp/vendorsetup.sh
Got local manifest

Success! Praise God! Now you can put this on your phone and test it out! Hopefully everything will be working! For future use, now you can start making changes or edits, from backgrounds to kernels! Have fun and make lots of backups. Remember, sometimes it is really hard to undo a change that you make.
Hopefully we learned how to set up our system, get the source, add devices and kernels that are not in the source, and run the compiler. Like I said, this works on my machine, as of this writing. You may notice, that if you make this build, it will not be identical to the one that I have posted on XDA. That is because I have made a few edits, additions, and/or subtractions here and there. That is the great thing about Android and open source! It is now up to you to make it better, to make it unique, or to make it you. Good luck with those builds, and be sure to share and help the next guy or gal with their projects too!
Post #3. Rom - How to add apps to your rom.
Post #3. Rom - How to add apps to your rom.
Here is the commit for when I did this to aokp_device_samsung_tblte-common:
https://github.com/alaskalinuxuser/...mmit/1ee34d6a1d5323a5ffb83eeeae7a87625f0eb130
I like to add the Kernel Adiutor app to my TBLTE (Samsung Galaxy Note Edge) builds. I used to put it in the vendor directory. What I realized though, is that I can simply add it to my tblte-common repository under the devices. For my device, I have a tbltexx repository, which essentially sets a few flags and passes the buck to the tblte-common repository for building. So, I actually added the app to my tblte-common repository. Now, when I sync, it updates my tblte-common directory, and keeps my prebuilt app!
Here is what I did.
Added some folders:
In my tblte-common repository (dev/samsung/tblte-common) I added a directory called "prebuilt". In keeping with Android's common structures, I then created these two folders: "common" and in that folder, one called "app".
When you are done making directories, it should have a path like this:
Code:
tblte-common/prebuilt/common/app
Now, in the "app" folder, I placed my prebuilt app, the Kernel Adiutor app, which I named "ka.apk". I then made an Android.mk file in the "prebuilt" folder that looks like this:
Code:
# Copyright (C) 2012 The Android Open Source Project

# limitations under the License.
LOCAL_PATH := $(call my-dir)
#
# Prebuilt APKs
#
include $(CLEAR_VARS)
LOCAL_MODULE := ka
LOCAL_MODULE_OWNER := aokp
LOCAL_SRC_FILES := common/app/$(LOCAL_MODULE).apk
LOCAL_MODULE_TAGS := optional
LOCAL_MODULE_SUFFIX := .apk
LOCAL_MODULE_CLASS := APPS
LOCAL_CERTIFICATE := PRESIGNED
include $(BUILD_PREBUILT)
You can add as many prebuilt apps as you want this way, just make the above block for each app. Then you simply add them to your tblte.mk file in the tblte-common directory. You can substitute your device name here, it should work the same. Notice that the lines which have more than one app have the "" denoting that there are more files to add. Then the last app line does not have a "". Pretty simple, right?
Code:
# WJH adding kernel adiutor apk and selinux plugin apk.
# These are found in tblte-common/prebuilt/common/app
PRODUCT_PACKAGES += \
ka \
selinuxplugin
Now, when you run your build, it will include the apps that you have added to the list and placed in your folder!
Post #4. Rom - How to change the default background in your source.
Post #4. Rom - How to change the default background in your source.
Sometimes you just want to change the background. So, download a custom background and edit the jpg until it was the right shape and size. I typically use Gimp for that. Then:
After making the jpg into a 1920x1280 jpg file, I then used my home built script to make all of the "default_wallpaper.jpg" files. Here is the script:
Code:
#!/bin/bash
echo "Changing name of jpg file."
mv *.jpg 1920x1280.jpg
echo "Converting to 1080x960"
convert -resize 1080x960 1920x1280.jpg 1080x960.jpg
echo "Converting to 960x800"
convert -resize 960x800 1920x1280.jpg 960x800.jpg
echo "Converting to 1440x1280"
convert -resize 1440x1280 1920x1280.jpg 1440x1280.jpg
echo "Converting to 2160x1920"
convert -resize 2160x1920 1920x1280.jpg 2160x1920.jpg
echo "Converting to 2880x2560"
convert -resize 2880x2560 1920x1280.jpg 2880x2560.jpg
echo "making folders"
mkdir ./drawable-hdpi
mkdir ./drawable-nodpi
mkdir ./drawable-sw600dp-nodpi
mkdir ./drawable-sw720dp-nodpi
mkdir ./drawable-xhdpi
mkdir ./drawable-xxhdpi
mkdir ./drawable-xxxhdpi
echo "copying and renaming pictures"
cp ./1080x960.jpg ./drawable-hdpi/default_wallpaper.jpg
cp ./960x800.jpg ./drawable-nodpi/default_wallpaper.jpg
cp ./1920x1280.jpg ./drawable-sw600dp-nodpi/default_wallpaper.jpg
cp ./1920x1280.jpg ./drawable-sw720dp-nodpi/default_wallpaper.jpg
cp ./1440x1280.jpg ./drawable-xhdpi/default_wallpaper.jpg
cp ./2160x1920.jpg ./drawable-xxhdpi/default_wallpaper.jpg
cp ./2880x2560.jpg ./drawable-xxxhdpi/default_wallpaper.jpg
echo "Complete."
echo "Move the drawable* folders to 'vendor/pac/overlay/common/frameworks/base/core/res/res' folder."
You have to have imagemagic installed on your machine to use this script. Then, simply place your jpg file in a folder by itself, and then put this script into the folder, and run it! Here is the output:
Code:
[email protected]:~/Documents/projects/phones/wallpapers/aokp/images$ ls
aokp.jpg picscriptphones.sh
[email protected]:~/Documents/projects/phones/wallpapers/aokp/images$ ./picscriptphones.sh
Changing name of jpg file.
Converting to 1080x960
Converting to 960x800
Converting to 1440x1280
Converting to 2160x1920
Converting to 2880x2560
making folders

Complete.
Move the drawable* folders to 'vendor/aokp/overlay/common/frameworks/base/core/res/res' folder.
[email protected]:~/Documents/projects/phones/wallpapers/aokp/images$ ls
1080x960.jpg 2160x1920.jpg drawable-hdpi drawable-sw720dp-nodpi drawable-xxxhdpi

1920x1280.jpg 960x800.jpg drawable-sw600dp-nodpi drawable-xxhdpi
[email protected]:~/Documents/projects/phones/wallpapers/aokp/images$ ls drawable-hdpi/
default_wallpaper.jpg
[email protected]:~/Documents/projects/phones/wallpapers/aokp/images$
Once I moved the drawable folders to the vendor/aokp/overlay/common/frameworks/base/core/res/res folder mentioned above, I simply re-ran the compiler. Viola! Changed default background!
Post #5. kernel - How to build just a kernel from a rom source.
Post #5. kernel - How to build just a kernel from a rom source.
This is the easiest way to build a kernel for your roms, as it will create the bootimage file for you after making the kernel.
Make the kernel and boot image:
If you followed Post #2 to download all of the source, and even built a rom from it, you can now build just the kernel very quickly with only a few commands.
You can go to the aokp/kernel/samsung/tblte/arch/arm/config folder and edit your defconfig, in this case apq8084_sec_defconfig and apq8084_sec_tblte_eur_defconfig to make changes if needed.
Then, go to your aokp folder and open a terminal:
Code:
$ . build/envsetup
$ breakfast tbltexx
$ make clean
$ mka bootimage
Each one of those commands will create a lot of output, but the mka bootimage command will run the compiler, make your kernel, and your boot image. Now they are in the aokp/out/target/product/tbltexx/ folder as kernel and boot.img.
Make it a flashable zip:
Make a new folder and put this file in it:
http://www.mediafire.com/file/x3cn41c1ucjs33x/makekernelzip.zip
Unzip that file and you will have everything you need. Simply put your boot.img file in this folder, and follow the included instructions to run zip.sh and make your boot.img flashable on any tblte phone.
Post #6. kernel - How to build just a kernel stand alone.
Post #6. kernel - How to build just a kernel stand alone, without Rom source...
For the record, I do not recommend building kernels this way, I recommend that you build them within your ROM source. This method will work, but is far more labor intensive.
Part 1 - The setup:
Go to
Code:
$ sudo apt-get install -y build-essential kernel-package libncurses5-dev bzip2 git make -y
This will take a while. Then:
Code:
$ cd ~
$ mkdir playground
$ cd playground/
$ mkdir toolchain
$ cd toolchain
Now type this for 4.9:
Code:
$ git clone https://android.googlesource.com/platform/prebuilts/gcc/linux-x86/arm/arm-linux-androideabi-4.9
OR this for 4.8, but for this I recommend 4.8.
Code:
$ git clone https://android.googlesource.com/platform/prebuilts/gcc/linux-x86/arm/arm-linux-androideabi-4.8
The output either way should look like this:
Code:
Cloning into 'arm-linux-androideabi-4.8'...
remote: Sending approximately 170.26 MiB ...
remote: Counting objects: 124, done
remote: Finding sources: 100% (124/124)
.........EDITED FOR SPACE..................
Resolving deltas: 100% (652/652), done.
Checking connectivity... done.
That will take a few minutes. Then:
Code:
$ mkdir kernel
$ cd kernel
$ git clone https://github.com/alaskalinuxuser/kernel_samsung_tblte.git
Cloning into 'kernel_samsung_tblte'...
remote: Counting objects: 49082, done.
remote: Compressing objects: 100% (32/32), done.
.........EDITED FOR SPACE..................
Checking connectivity... done.
Checking out files: 100% (46422/46422), done.
This will take another few minutes, maybe longer, depending on your internet connection.
Part 2 - The kernel modifications
Before going further, this is when you can edit the files of the kernel, add things, remove things from the kernel itself. See the other posts here for how to do that. When you are ready, you can move onto the build.
Part 3 - The build
Open ~/playground/toolchain/kernel/kernel_samsung_tblte/Makefile, and go to line 195, it should say ARCH, edit it as such:
Code:
ARCH =arm
CROSS_COMPILE =/home/{YOURUSERNAME}/playground/toolchain/arm-linux-androideabi-4.8/bin/arm-linux-androideabi-
Code:
$ cd ~/playground/toolchain/kernel/kernel_samsung_tblte/
$ make clean
$ make mrproper
You will likely see an error about TARGET, that is okay, just ignore it.
Code:
$ make menuconfig apq8084_sec_defconfig
OR
Code:
$ make menuconfig apq8084_sec_tblte_eur_defconfig
After some scrolling text, you will see a menu option. Use the arrow keys and the space bar to make selections. Make any changes you want. Remember, not all changes are good. With this setup, you will need to make changes to make this function.
Once you are done, select exit. Then select yes to save your config.
Now that you are back at the command line, all you have to do is type one more command:
Code:
$ make
You will see a lot of scrolling text, like this:
Code:
arch/arm/kernel/return_address.c:63:2: warning: #warning "TODO: return_address should use unwind tables" [-Wcpp]
#warning "TODO: return_address should use unwind tables"
^
CC arch/arm/kernel/sched_clock.o
CC arch/arm/kernel/setup.o
CC arch/arm/kernel/signal.o
CC arch/arm/kernel/stacktrace.o
CC arch/arm/kernel/sys_arm.o
CC arch/arm/kernel/time.o
CC arch/arm/kernel/traps.o
CC arch/arm/kernel/atags_parse.o
CC arch/arm/kernel/cpuidle.o
This is good. Make is making your kernel.
If you are good, or lucky, then it will compile successfully, if not, it will error. Check your changes and use Google to search for errors if you need help. Again, I recommend to build kernels within the backdrop of ROM source, as I mentioned in the other post, it is much, much easier. This method will work, but you may have to add or change a lot of options in your config to make it happen.
Good luck!
Make it a flashable zip:
You will need to follow Post #7 and break down another boot image, insert your kernel, then re-pack that boot image with all of the proper arguments. This is the main reason I do not recommend building a kernel for Android outside of rom source.
Post #7. Kernel - How to break down and make boot images.
Post #7. Kernel - How to break down and make boot images.
Breaking down a boot image:
Okay, so first things first, STEP 1: downloads!
Download these things:
http://www.mediafire.com/download/zl80gh0t310trla/unpack-bootimg.pl
http://www.mediafire.com/download/xdmd278n17gm58h/unmkbootimg
http://www.mediafire.com/download/byf0tw4ga2mqtw0/repack-bootimg.pl
http://www.mediafire.com/download/7cmi548pzetc6c4/mkbootimg
And download your boot image that you want to break down, if you have not already.
I am using Linux, Ubuntu 14.04. I did this previously from Debian Wheezy, so any Linux should work. You can also use a VM, virtualbox, etc. if you are on a Windows computer.
STEP 2: Unzip!
Go ahead and unzip the zipfile if you are breaking down a flashable kernel zip that you downloaded. Preferably in its very own folder. For my work, I made a folder called "playground" in my home directory to play around in. I will reference the "playground" meaning the main folder with everything in it. Now, in the playground, make a new folder called "bootimage". In the playground folder, copy the boot.img file to the bootimage folder.
STEP 3: Tools setup!
Copy the downloaded above tools into a new folder called "tools" in the playground folder. Open a terminal here and give these files executable permissions and copy them again to the bootimage folder:
Code:
$ cd ~/playground/tools
$ chmod 777 ./*
$ cp ./ ../bootimage
We copy this twice so we have backups of the tools in case we delete them accidentally.
STEP 4: Unpack the boot image!
Open a terminal and go to the bootimage folder, and start typing:
Code:
$ cd ~/playground/boot.img
$ ./unmkbootimg ./boot.img
You will see some output in the terminal that looks *kind of* like this:
Code:
$ ./unmkbootimg ./boot.img
unmkbootimg version 1.2 - Mikael Q Kuisma <[email protected]>
Kernel size 2992704
Kernel address 0x10008000
Ramdisk size 2196028
Ramdisk address 0x11000000
Secondary size 0
Secondary address 0x10f00000
Kernel tags address 0x10000100
Flash page size 2048
Board name is ""
Command line ""
This image is built using standard mkbootimg
Extracting kernel to file zImage ...
Extracting root filesystem to file initramfs.cpio.gz ...
All done.
---------------
To recompile this image, use:
mkbootimg --kernel zImage --ramdisk initramfs.cpio.gz -o new_boot.img
---------------
Whatever it says, copy and paste it, hand type it, screenshot, whatever it takes, write the output down, because this is the key to re-making your boot image!
Then, you can unpack it like so:
Code:
$ ./unpack-bootimg.pl ./boot.img
You should see something *like* this:
Code:
$ ./unpack-bootimg.pl ./boot.img
kernel written to ./boot.img-kernel.gz
ramdisk written to ./boot.img-ramdisk.cpio.gz
7607 blocks
extracted ramdisk contents to directory ./boot.img-ramdisk/
You will now have folders and files to play with!
Make changes to your boot image:
Now is the time to change any files you want, such as delete the kernel and put yours in instead, etc. I can not tell you much about this, since I don't know what you are doing in your boot image. Here is an example of me turning a Captivate glide cell phone into a Debian "laptop":
http://forum.xda-developers.com/cap...msung-captivate-glide-debian-chatter-t3233807
Re-pack the boot.img:
Okay, so you have made your changes, now it is time to put it back together. Go back to your playground folder.
Code:
$ cd ~/playground/bootimage
$ rm initramfs.cpio.gz
$ cd ./boot.img-ramdisk/
$ sudo su
<enter your password>
# find . | cpio --quiet -H newc -o | gzip > ../initramfs.cpio.gz
# cd ..
# mkbootimg --kernel zImage --ramdisk initramfs.cpio.gz --base 0x0 --cmdline 'console=ttyS1,115200n8 androidboot.selinux=permissive' -o new_boot.img
Note that the last part, "mkbootimg" needs to be all the stuff I told you to write down when you broke down your boot image, or it needs to be the new command line you want your boot image to use. The new_boot.img is your newly created boot image file, which you should rename boot.img, after you remove your old boot.img file from the folder.
-With heimdall, heimdall-frontend, or Odin, flash the new_boot.img to the boot partition of your phone, or make it flashable per Post #5 or Post #6.
Post #8. kernel - How to add CPU/GPU Governors.
Post #8. kernel - How to add CPU/GPU Governors.
Where to get CPU and GPU governors:
That is a really great question. Essentially, for CPU governors, you can pull them from any kernel by searching github. However, I recommend you pull from a kernel from either the same phone and/or kernel version. If you are using 3.10.40, but you pull from a kernel that is 3.10.84, there may be dependencies that are missing from your older kernel. In the case of the Nightmare example, I had to edit the governor itself to make it work with the kernel I was using.
For sure, if you follow this guide, you can always borrow mine
https://github.com/alaskalinuxuser/kernel_samsung_tblte
They will come from the drivers/cpufreq/ folder, and should be named cpufreq_{governor_name.c}. So, if you are looking for Nightmare, you can search github for cpufreq_nightmare.c, or use Google with "github cpufreq_nightmare.c".
GPU governors are a bit more complicated, see below for how to implement one, and then you can better see where to get one.
The non-technical guide to understanding CPU/GPU governors:

Adding CPU Governors:
Adding a kernel governor can be a Nightmare!
You can read the commit here: https://github.com/alaskalinuxuser/...mmit/19ba1b4f94d04877a5a783843a01c2494ecb1d5c
Okay, so a little play on words, especially since I am adding the Nightmare governor to the kernel, but it did turn out to be a bit of a problem child, fortunately, it was quickly corrected. As you can see, I did the standard additions, as well as adding the cpufreq_nightmare.c file: https://github.com/alaskalinuxuser/...94ecb1d5c/drivers/cpufreq/cpufreq_nightmare.c You can download it there.

Post #9. kernel - How to Overclock/Undervolt.
Overclock an apq8084 Samsung Galaxy Note Edge!
You can see the commit on github here:
https://github.com/alaskalinuxuser/...mmit/9bb23d0d9cc805bf7e1b8e3fe829fcbb0542af31
In my continuing quest to make a better kernel for the Samsung Galaxy Note Edge (TBLTE, N915T), I decided to tackle overclocking the kernel. There are already some overclocked kernels out there, but I decided to do something slightly different with mine. The distinguishing feature of my overclocked kernel is that it doesn't use any more power than it did before, and to God be the glory, it worked!
I also feel that when you overclock a chip, you are increasing the rate of failure, and the induced heat load. So I like to keep my overclocking light, less than 10% of the overall capacity that the chip was designed for. It is my hope that this will reduce wear and tear on the device while still providing superior performance.
Editing the tables for this chip was a lot simpler than for other chips I have worked on.
It all took place within the kernel/samsung/tblte/arch/arm/boot/dts/qcom/apq8084.dtsi file. Here is how it used to look:
Code:
.............EDITED FOR SPACE................
/* 2.7GHz RC1 */
qcom,speed2-pvs0-bin-v1 =
< 0 0 0 >,
< 300000000 810000 76 >,
< 345600000 820000 88 >,
.............EDITED FOR SPACE................
< 2496000000 1120000 813 >,
< 2572800000 1135000 849 >,
< 2649600000 1150000 886 >;
And here was my change, from 2649600000 to 2688000000:
Code:
.............EDITED FOR SPACE................
/* 2.7GHz RC1 */
qcom,speed2-pvs0-bin-v1 =
< 0 0 0 >,
< 300000000 810000 76 >,
< 345600000 820000 88 >,
.............EDITED FOR SPACE................
< 2496000000 1120000 813 >,
< 2572800000 1135000 849 >,
< 2688000000 1150000 886 >;
That's right, I only made a 39MHz change. I feel this was appropriate to keep the device cool and continue to use the same voltages. So it is essentially a 39MHz boost with no noticable consequences. Of course, I had to do the above to each speed and pvs table in that file.
Then, I needed to edit this portion:
Code:
.............EDITED FOR SPACE................
qcom,[email protected] {
reg = <0 4>;
compatible = "qcom,msm-cpufreq";
qcom,cpu-mem-ports = <1 512>;
qcom,cpufreq-table =
< 300000 300000 1144 800 >,
< 422400 422400 2288 800 >,
.............EDITED FOR SPACE................

.............EDITED FOR SPACE................
To this:
Code:

reg = <0 4>;
compatible = "qcom,msm-cpufreq";
qcom,cpu-mem-ports = <1 512>;

.............EDITED FOR SPACE................
It actually was the only time I have overclocked a kernel on the second try. Don't think too highly of me, though, I spent hours reviewing kernel edits for overclocking by various other kernel developers on GitHub. If you are looking to do the same, you should spend some time looking at working code for others, and then make your own tables.
If you try this on your own, you may have multiple tries where the phone will not even boot, or crashes while you use it, so be careful, make small changes, and be courageous, because this is usually not a simple one stop process.
If you were to compare my tables with everyone elses, you would see that I have done it differently than my contemporaries, even though we reached similar, or in some cases, identical results. I like to keep the code clean, short, and sweet. Often when overclocking, most kernel developers will add more lines to the tables. I have found that while that may be the best to maximize use, my method is much simpler and easy to implement, as well as follow, and that is what Linux should be all about, keeping it simple. It also makes it easier for "stock" kernel hot-plug controllers like MPDecision.
Under-volt a Samsung Galaxy Note Edge:
So, back to our ealier example of the overclocked chip, now we want to change the voltage. Doing that is easy, getting viable, stable, working results is much harder. Consider our code from the kernel/samsung/tblte/arch/arm/boot/dts/qcom/apq8084.dtsi file:
Code:
.............EDITED FOR SPACE................
/* 2.7GHz RC1 */
qcom,speed2-pvs0-bin-v1 =
< 0 0 0 >,
< 300000000 810000 76 >,
< 345600000 820000 88 >,
.............EDITED FOR SPACE................
< 2496000000 1120000 813 >,
< 2572800000 1135000 849 >,
< 2649600000 1150000 886 >;
To change the voltage, one only has to edit these multiple pvs trees.
Consider this line:
Code:
< 2572800000 1135000 849 >
It means:
Code:
< Frequency Voltage Amperage (? or cycles) >
So, in the above table, the 2572 MHz frequency uses 113.5 mv.
And, in the above table, the 2649 MHz frequency uses 115 mv.
So, to under-volt you could edit it like so:
Code:
< 2572800000 1120000 849 >,
< 2649600000 1135000 886 >;
This would cut down the voltage used on each of these frequencies. The problem is, however, if you go too low, you may cause the kernel to crash. Notice that in my overclocked kernel, I under-volted it to the same as the 2649 MHz frequency, even though I am using it at 2688 MHz. So, use with caution, and have fun making adjustments! I recommend only small changes or even only one change at a time.
Post #10. kernel - "How to" on special projects like sound mods and I/O schedulers.
Post #10. kernel - "How to" on special projects like sound mods and I/O schedulers.
How to add an I/O Scheduler to your kernel:
Praise God, another great addition to the TBLTE kernel was that of adding the FIOPS I/O scheduler to the kernel. What is an I/O scheduler? Well it is the part of the kernel that handles, or schedules, input and output. Particularly, this has to do with writing and reading to and from media, like your hard drive, flash drive, etc.
So, how do we do that? How do we add I/O schedulers to our kernel?
Well, for the TBLTE kernel, I will show you what I did, and you can add to your kernel similarly.
Go to the block folder in your kernel source. The first thing that you need to do is add the fiops-iosched.c file. Whatever I/O scheduler you want to add will be named like this: {NAME-iosched.c} you can search Google or github for them, or take them from my source if you would like.
Once you put your fiops-iosched.c file in your kernel's ./block/ folder, you can now edit two other files in that folder. You need to add the new scheduler to the make file, so it knows to make it, you can do that like so:
Open ./block/Makefile and add this line after the other *-iosched.o lines:
Code:
obj-$(CONFIG_IOSCHED_FIOPS) += fiops-iosched.o
Notice that it just uses the name of the iosched file, but with an ".o" extension instead of a ".c" extension. The ".c" file you added earlier will create a ".o" (object) file that the Kernel needs to use to "make" the kernel.
Now edit the ./block/Kconfig.iosched file like so:
Code:
config IOSCHED_FIOPS
tristate "FIOPS I/O scheduler"
default y
---help---
The FIOPS I/O scheduler. WJH.
This way, when you are moddifying your configuration, you can select to build it. Notice that it is a "default y", essentially, I am telling the config file creator to allways assume I want to build this, unless I choose not to. You can also eddit the "---help---" portion to say anything you want. I put my initials in there so I can find it easily with the search tool.
Now open your configuration file. For the stock builds, that would be ./arch/arm/configs/ap88084_sec_defconfig, and add this line:
Code:
CONFIG_IOSCHED_FIOPS=y
Note that you could also do this through
Code:
$ make menuconfig
.
You may also note, since we gave it a "default y" in the Kconfig.iosched file, we don't actually need to add this to our configs, as it will be built by default, but I like to declare what I am building in my configs so I remember what I am doing.
There you go! Now when you build your kernel again, the FIOPS I/O scheduler will be added in. It is remarkably simple, just the way I like it. You can read the commit here: https://github.com/alaskalinuxuser/...mmit/f80320a895612bd1379ca789f88f1d6dfd6e68f9

I will teach you to build Nougat roms here also, if you are interested.
@AlaskaLinuxUser
I appreciate the help with teaching me what I need to do with our Note Edge. As far as I know, I need Linux, latest OpenJDK for building with Nougat and beyond. I have read up some basics, but I don't know all the particulars that go into the Note Edge.

I would also like to ask, you mentioned earlier in the guide that you had an HP Compaq 6715b. How long were compile times? I have an HP Elitebook 8540w with an Intel i5 520m, so I am assuming that compile would probably take about 6 hours?

Click to collapse
No problem.
Your laptop should work. It took me 11 hours to compile on my old laptop. Now I use a server with 24 GB of ram, 8 cores (2x4 core 2.0 GHz) and it takes 3 hours to compile. I can only guess, but it will likely take 6 hours on your machine. The great thing is, starting with Nougat, the builds now use Ninja, so you can see the progress in percentage. Before, in MM and down, we just had to wait, without knowing how far along it was. We could guess by looking at the files, but it is not always built in the same order.
Okay, to get started. If that laptop is your machine, you can't set up a virtual box, because you need all 8 GB of ram (unless you have more than that). So, I recommend installing Ubuntu 14.04, 64 bit. 14.04 is still Google's preferred OS for building Android, but you can do it on other systems. I recommend for now that you do install 14.04 or 16.04 as your build environment. Once you get good at the builds, then you can experiment with other OS' for the builds.
After you install that, follow post #2, with these changes for Nougat:
I am only listing the changes, otherwise, follow the steps as is.
<<<<< Step 1: Setup your system. >>>>>

After you install that, but before you install the "curl repo" part, install openjdk-8-jdk per here:

<<<<< Step 4: Editing the device, kernel, and vendor trees. >>>>>
No changes.
<<<<< Step 5: Start your build! >>>>>
No changes. But....
Not required, but if you want the capacitive buttons to work correctly, before you compile, do this from the aokp7 directory:
$ sh device/samsung/tblte-common/run_before_compiling.sh
It runs a little script that overwrites the generic keyboard layout.
Now you can continue with the
$ . build/envsetup.sh
When you get to brunch tbltexx:
$ brunch tbltexx
-- OR --
$ brunch tbltetmo
To build for the international or T-mobile versions.
Okay, that should get you started. I will gladly assist once you get rolling.
I guess I should have asked: Are you planning to build MM or Nougat? I figured Nougat, so do the above to build Nougat. For learning purposes, you could follow the guide as written to build MM instead.
@AlaskaLinuxUser
For some reason, my post didn't go through. Anyways, I tried to mention I am building Nougat, and waiting until I go up to my Grandparents where they have an HP Workstation with an Intel Core 2 Quad q9600 and 6gb ram, their computer is more dedicated for the job. But for bow, I have been running new LineageOS builds with Micky387's RR kernel and his Key Layout files, so I may build kernels only on my laptop. If will probably post up a zip including the keylayout files and my own built lineageos kernel for now so people can have new builds until I start building explicitly for the Note Edge.

Sorry about my large absence from this ROM build. My computer had broken down, so I worked on fixing it, also found a cheap PC on eBay which will serve builds much better. Intel i5 2400 with 8gb ram and 500gb hdd, so I should have a lot more room and power for builds. I had also started my own TouchWiz project called Slaughtered ROM and was busy with that, I will soon set up the build environment and get that going, thank you again for the guide and sorry for how long I had been busy.
I will start with AOKP, but probably push towards Resurrection Remix and possibly seeing if I can build AOSP O on the Edge.

Thanks for your help! I have synced RR repo's, I wanted to try building RR, and am in the process of setting it up with the device-specific stuff, afterwards I will start building.
Introduction & Setting Up Build Environment
Well hello everyone today I will teach you “How to build custom ROM’s for your device from source”. So, if you are interested then please continue to read. So, first of all, you must know how Linux work and few commands for that you can simply visit here
I guess you are done with commands now let's move ahead. First and for most important… You must have a high specs PC like with i7, 16gb ram, 512gb SSD. If yes then move ahead if no then look for online cloud services like GCloud/AWS.
Setting Up Environment for the build!
Woo-ho! We will set up the environment for the build now …
Now install Linux in your PC. You can install any distro but I would suggest installing Ubuntu 16.04.
Just copy paste below codes and if asked for y/n then type y and hit enter, all set!
Code:
sudo apt-get update && sudo apt-get install git-core gnupg flex bison gperf build-essential zip curl zlib1g-dev gcc-multilib g++-multilib libc6-dev-i386 lib32ncurses5-dev x11proto-core-dev libx11-dev lib32z-dev libgl1-mesa-dev libxml2-utils xsltproc unzip openjdk-8-jdk openjdk-11-jdk && sudo apt-get upgrade
Code:
git clone https://github.com/akhilnarang/scripts.git ~/scripts
cd scripts
bash setup/android_build_env.sh
All set! As mentioned earlier allow the packages to be installed by typing “y” if asked.
Syncing Sources
Now look for your favorite ROM sources like for me its lineage so source are here
After you are done with your sources just clone the source but before that let's make a directory where we will store our source like for me I am using android/lineage for your ROM you can change as per your wish! Well if you still didn’t get your ROM sources then I will drop down link below of my top 5 favorite ROM sources!
Now let's make our directory
Code:
mkdir android/lineage && cd android/lineage
Now let’s initialize our ROM repo like for me its lineage, but for you change it as per your ROM. Here for your info after “-b” is your branch you will have to look for your ROM and change accordingly.
Code:
repo init -u git://github.com/LineageOS/android.git -b lineage-16.0
Well, now you will encounter a small error to fix it up just copy below code.
Code:
git config --global user.email "[email protected]"
git config --global user.name "Your Name"
Replace [email protected] & “Your Name with your GitHub account email and username respectively. After that re-initize source.
Wow, it’s for Pie hehehe but it’s not yet done. We have just initialized source we are yet let to sync it. but before that please note source size is about 60-80gb so make sure you have enough bandwidth with high speed …
Now let’s sync our source
Code:
repo sync -f –-no-tags –-no-clone-bundle
Well, now you can do only one thing that is wait ... as repo is long (60g-80gb)
Done? Then why to wait just start with syncing device related sources.
Now you must be wondering what are they and why we need those… So, device related sources are of the device tree, kernel source, vendor blobs. You can find those by searching your device codename like for me I will search k5fpr device tree, k5fpr kernel source, k5fpr vendor tree (Here k5fpr is my device codename you change as per your device.) Now I got these links
DT : https://github.com/SahilSonar/android_device_lenovo_k5fpr
Kernel Source : https://github.com/SahilSonar/android_kernel_lenovo_k5fpr
Vendor Blobs/Tree : https://github.com/SahilSonar/android_vendor_lenovo_k5fpr
Well, now you don’t use these until and unless you want to build for k5fpr. You look for your device and now let’s clone them to our working dir. Again as dir. may change please edit the code as per your ROM
Code:
git clone https://github.com/SahilSonar/android_device_lenovo_k5fpr.git -b lineage-15.1 ~/android/lineage/device /lenovo/k5fpr
git clone https://github.com/SahilSonar/android_kernel _lenovo_k5fpr.git -b lineage-15.1 ~/android/lineage/kernel /lenovo/k5fpr
git clone https://github.com/SahilSonar/android_vendor _lenovo_k5fpr.git -b lineage-15.1 ~/android/lineage/vendor /lenovo/k5fpr
Now after -b is our branch just look one there in your source, which one you want to use just change it now most of the people must have thought hey man there is another way for this … We can use manifest… yes, those are 100000% but cloning is an easy way instead of manifest but still for those who want to clone using manifest then simply follow below steps instead of above … No issue you can use anyone.
First, let’s move to the dir where we are supposed to add manifest like for me its android/lineage/.repo You will have to change as per your dir.
Code:
cd android/lineage/.repo && mkdir local_manifests && cd local_manifests && nano roomservice.xml
After pasting above code you will see a text editor in that we are supposed to paste our manifest okay I am giving manifest of k5fpr you change source as per your device.
Code:
<?xml version="1.0" encoding="UTF-8"?>
<manifest>
<project path="device/lenovo/k5fpr" name="mohancm/android_device_lenovo_A7010a48" remote="github" revision="oreo" />
<project path="vendor/lenovo/k5fpr" name="mohancm/android_vendor_lenovo_k5fpr" remote="github" revision="oreo" />
<project path="kernel/lenovo/k5fpr" name="mohancm/android_kernel_lenovo_A7010a48" remote="github" revision="oreo" />
</manifest>
Okay, so you must be wondering what to do for my device… Well don’t worry as we have used -b here its revision so after revision what comes is our branch and after “name” it's our source link and after “path” it's our destination like we have used ~/android/lineage/device/lenovo/k5fpr. That’s all for manifest just save it and exit after that just sync sources again … Whoa man, I don’t have 60-80gb left. Well, don’t worry its just loads the repo which is downloaded also it only fetches device specific sources.
Code:
repo sync -f –-no-tags –-no-clone-bundle
Patches & Bring-up!
Now let it finish syncing and after that, we will apply patches. Yes! Patches now most of you must be thinking what are those? Well, patches are nothing more than fixes they are located in your device tree(android/lineage/device/lenovo/k5fpr/patches) Now look there and see which patches you want to apply. If you are confused which to apply then simply apply all. Whoa man, we are new and no idea how to apply those. Well I know don’t worry I will teach you same now.
First of all copy patches from device tree to our source like for e.g I will show you how to apply bionic_libc.patch.
Code:
cp ~/android/lineage/device/lenovo/k5fpr/patches/bionic/bionic_libc.patch ~/android/lineage/bionic
Now what comes after bionic_libc.patch is our destination where we are copying our patch. For your info “cp” is nothing then copy. Now just apply it by using below codes.
Code:
cd android/lineage
git add .
git commit -m “Patch”
Now you are done with applyin bionic_libc. patch but there are many other patches left do same with those just change their dir location like we choose/bionic/bionic_lib.patch same way for other patches just changes as accordingly.
Now after you are done applying all patches lets build our ROM … Oh! Yea finally.
Well not yet before that will learn a new thing called as “bing-up” well not device is universal for every ROM but there are some changes needed to be done before you build for any ROM like for me my device tree is already on lineage but if in case I want to build aosp or rr or any other ROM I will have to do certain changes in device tree for that particular ROM. Like here we will choose AOSP.
Now move to device tree like here in my case
Code:
cd ~/android/lineage/device/lenovo/k5fpr
Now following things will require changes :
*AndroidProducts.mk
*lineage.mk (Now pretty tricky this file name is lineage if your source is for dot just consider then its dot .mk)
*vendorsetup.sh
Just these 3 needed few changes now pay careful attention or else you won't get what I am saying. Now here we are doing bring-up for aosp from lineage so first and for most, we will start with AndroidProducts.mk so I am showing before bring-up and after bring-up (These changes are done using notepad like nano AndroidProducts.mk)
Before
Code:
PRODUCT_MAKEFILES := \
$(LOCAL_DIR)/lineage.mk
After
Code:
PRODUCT_MAKEFILES := \
$(LOCAL_DIR)/aosp_k5fpr.mk
Now if you can see then we have changed lineage.mk to aosp_k5fpr.mk… yes for newer oses like pie we will have to include device code name as we did so here you are supposed to change lineage to aosp_k5fpr. Well, now we will talk about lineage.mk itself as we have changed it to aosp_k5fpr there then let's change the name of the file itself for that save the change and exit notepad and copy below code to rename it.
Code:
mv lineage.mk aosp_k5fpr.mk
Here you can observe we have typed lineage.mk at first so it means we want to change this file name and to what after space we typed aosp_k5fpr.mk. This means you will have to change it as per your current makefile and to which you want. Now open aosp_k5fpr.mk by using nano aosp_k5fpr.mk

PRODUCT_DEVICE := k5fpr
PRODUCT_MANUFACTURER := LENOVO
PRODUCT_MODEL := Lenovo K4 Note
PRODUCT_NAME := aosp_k5fpr
PRODUCT_RELEASE_NAME := k5fpr
PRODUCT_RESTRICT_VENDOR_FILES := false
Now if you observe we removed a line “
# Inherit some common lineage stuff.
$(call inherit-product, vendor/lineage/config/common_full_phone.mk)
“ Well in aosp there is no common_full_phone.mk so we removed entire but for most of the ROM’s its common.mk So make sure you check that out. Also, path will be changed like vendor/dot/config/common.mk for dot but for aosp there is nothing so we removed. Now also we did a change to PRODUCT_NAME : aosp_k5fpr from lineage_k5fpr.mk Well that all changes needed just save it and move to last but not the least vendorsetup.sh. Just open it by nano vendorsetup.sh
Before
Code:
add_lunch_combo lineage_k5fpr-eng
add_lunch_combo lineage_k5fpr-userdebug
add_lunch_combo lineage_k5fpr-user
After
Code:
add_lunch_combo aosp_k5fpr-eng
add_lunch_combo aosp_k5fpr-userdebug
add_lunch_combo aosp_k5fpr-user
This was a simple change just aosp from the lineage that all save it and let's start building now … Wait we did bring-up just for teaching you how exactly it works but doesn’t use aosp bring-up for lineage. Also if you still see some error cannot locate makefile for your device then try changing aosp_k5fpr.mk to aosp.mk and also in AndroidProducts.mk If still not then see for common.mk file or can seek your maintainer who has made trees.
Building ROM & Basic Info regarding errors!
Now let's start the build
Code:
. build/envsetup.sh
export USE_CCACHE=1
export LC_ALL=C
brunch aosp_k5fpr-userdebug
Now we used userdebug but I would suggest eng as debugging is on by default so as to pull logs in case ROM doesn’t boot and wont to know what went wrong. For your info “export LC_ALL=C” Enables local time as it fixes up an error which new kernel causes due to improper time. “export USE_CCACHE=1” Enables cache, now cache speed up build. If you want to know more about lunch, brunch, mka and make just read this
Now building takes a long time as of me it took ~ 5hrs but I am sure it takes around ~6 hrs.
Also some basics… Now you will see many things in screen just ignore those as you may see “warning’s” well those are normal and will see those don’t worry about those but if you see something like “error” or “failed” That means something is wrong with certain file just ask Android ROM Development Group (Telegram)about the error as I cannot help with device-related errors. Also, these errors are due to device tree issues most of the cases as your maintainer has not maintained tree properly or due to some changes required for bring-up! Additionally, your device tree may also contain build manual just have a look at it
You forgot to add build guide for Snapdragon as you said MTK and Snapdragon are different.
Good guide btw.
