This is a continuation of the "Compiling CM6 for Eris" thread - http://forum.xda-developers.com/showthread.php?t=856215. But since Team ADX has really come together on this, we are releasing it in it's new form.
Thanks to workshed for working to get the Eris on the Official CM list and merged into the main repo. And also, thanks to workshed for most of the v6 --> v7 changes to EasyDev!
This script will grab CM7 source and compile a CM7 ROM for you using the official vendor tree that is built-in to the CM source. You have the option of including Google Apps or not.
Uses:
CM source - https://github.com/CyanogenMod/android.git
Conap's CFS kernel that's built-in to CM source - https://github.com/Conap30/htc_kernel_desirec_cfs
Requirements
-------------
1) 64- bit Linux -tested on Debian, Ubuntu 10.04, Linux Mint (if you have a different flavor of linux and easydev worked for you, please let us know so we can update this list)
2) An existing Eris ROM that the script will pull the proprietary files from.
INSTRUCTIONS
1) Download the script
2) 'chmod a+x easydev-v9.sh'
3) copy it to the directory of your choice or leave it where it is
4) copy an existing ROM to the same directory (tested with GSB, but most should work)
5) run it ('sudo ./easydev-v9.sh')
Possilbe future features:
Done.
Changelog
v1 - initial release
v2 - added squisher, made 'make clean' optional, added installation of dependencies, cleaned up output
v3 - uses existing ROM to pull proprietary files, renamed to 'easydev' for case sensitive linux admins
v4 - fixed file missing from list in unzip-files.sh in vendor tree, fixed move/rename of existing ROM, change 'make clean' option to default to no instead of yes
v5 - added 'apt-get update' to refresh repo list (should install dependencies now), swapped order of extract-files and unzip-files to fix 'chmod akmd' issue, tried not to break anything else
v6 - moved questions to beginning of script, added check to only init repo the first time, added check for existing ROM, modded vendor tree to fix compile issues
v7 - removed CM6 stuff, removed kernel compilation code, removed vendor tree code, changed from CM6 to CM7, fixed path bug, added 32-bit libs to dep list
v8 - added ALL official CM devices (mostly untested), minor update to dependency installer code (4-21-11)
v9 - added an extra check for correct Java version, fixed .zip rename issue

v7+ --> https://github.com/gnarlyc/EasyDev-Eris
NOTE: If you have issues with google setup or not being able to pass andy the android at the beginning of setup, please delete Provisions.apk for system/app you shouldn't have a problem, but just incase, this will remedy it. -workshed
I'm all over this sh*t
Oh damn, I'm excited for this. good thing I use ubuntu!

Nice! I will be trying this later.
This is awesome! Thanks alot. What does the 'make clean' option do?

The make clean removes everything that has been compile so far leaving only the original source.

It removes any previously built ROMs, etc. It's not needed every time, so I've made it optional in the next version. The problem was that sometimes the script would be broken in some way and wouldn't build a ROM. But, there's so much text displayed to the screen, it's not always easy to notice. So, I was actually flashing the same test ROM over and over instead of getting a new build...
Great work guys. Going to try it out on Arch Linux and if anyone's interested I'll give details about how to get it working there (or just modify the script to detect Arch as opposed to Ubuntu and work accordingly.
<gripe>One complaint: commands (including scripts) should *always* start with a lowercase letter </gripe>
good work gnarlyc & conap.
this sounds great and i will be trying this when i get home. I have just one question. Why would i want to run this instead of conap's rom? Both being pure CM. I see alot of the other cm6 roms have stuff themed, but conap's rom doesn't. I'm assuming this is complete pure cm without little tweaks done by devs of the respective roms. Thanks in advance.

Some people just like to "roll their own", more or less. If you like having someone else make improvements and fix issues for you, then you'll probably want to stick with another ROM.
I would love to make my own fixes and tweaks but i dont have the knowledge nor the time to gain said knowledge. guess i will just stick with the devs roms. thanks
Very very exciting. I am installing Ubunto 10.4 now. So does EasyDev-v2 pull from the CM6 nightlies or the stable version and can we change where it pulls from for the CM6 source. This is great.
Will have to check this out later. Always wanted to understand the compile process, always to busy with other software projects. Thanks for building this resource for the rest of us.

Hmmm. Someone correct me if I'm wrong, but I'm pretty sure that this is currently grabbing 'stable'.
Code:
repo init -u git://github.com/CyanogenMod/android.git -b froyo
I'm thinking that to get the nightly, we'll have to change that to:
Code:
repo init -u git://github.com/CyanogenMod/android.git -b master
I'll try it as soon as I can. You got me to thinking that we could add that as an option, if I understand this correctly.
Nightly vs Stable
Yes, you answered my question regarding nightly and stable. I am having fun so far. I got all the necessary packages installed. That was pretty easy using the Ubunto package manager deal. So where do I find the proprietary.zip now? I am almost there to cook this sucker up.

I was apparently wrong about the "-b master" switch, but I think I mostly got it right...
Right now, you'll have to grab the files listed in the OP and zip them up into a file called 'proprietary.zip'. Then place it in the same directory that you run the script from.
I'm working on a way that you can just place an existing ROM there, and it will extract the proprietary files for you. That should be in v3.
Proprietary.zip Files
Can I download CELB Froyo 3.8 and uncompress it and do searches for those files and pull them out and zip them up?

Hey been looking around through xda for a bit but couldnt find anything.
Im after a guide on how to start making my own ROM.
If anyone could post a link to a guide or let me know the important steps on how to start.
Had a U8800 for a bit and love it and want to make it perfect
Cheers
first you have to understand some programming language , specifically c or java, but most high level languages are similar
then I am told that you need to have a deep understanding of linux file system, which I don't... so I am not qualified to give you anymore advice...
For me I started out trying to port clockwork recovery to u8800. There's a guide by koush that gives the most basic steps on how to do this. Following that and doing a lot of reading I was able to get it pretty good and obviously Geno has since taken over to basically perfect it.
I think the recovery is a good place to start since it's similar to the normal android os but just really cut down. Try building it from source and work out how to get it on the phone and booted.
As well as Stockwell's very useful suggestion (do you have a link to the specific koush guide that you found useful, Stockwell?), you might want to go to XDA's Chef Central, and cyanogen's advice at :-

I think it's missing some stuff though. At the very least it looks like you would need to do
. build/envsetup.sh before running lunch. I think there was another problem but I can't remember what it was now.
Thanks everyone for the info.
I am studying IT at the moment and am about to learn java so sort of wanted something to have a go at while learning
this is not to rush the devs, just asking, are they gonna wait till ( i really hope it actually hapens) jb update comes to us to start developing? couse i think our phone haves a lot more to give to us than the stock rom can, again i am not rushing the devs, just asking your oppinion, and since im kinda new to theese forums hardly think any dev is going to bother to even answer this thread
so im pretty much.asking your oppinion
this is just a question , please dont kill me

If you mean Custom Roms... we can't do anything until we can pack / unpack the boot.img/or recovery.img to make a custom recovery.
jeah thats right, i was wondering because my expirience with atrix 2 , previous to the ics update, i was using supercharger rom series, but again i understand that they got a leak to work on, and a bootstrap to flash the restores they where creating, and that stock leaked rom was awesome

Would be nice to know for sure. The current methods cannot find 'Android Magic'.
I'm looking forward to seeing this forum get some custom ROMs too...
Looks like progress is getting on with it now
Any updates on custom ROM making for this device?
I've followed the README from <link to Motorola's sourceforge for razr i, deleted because I'm a new user> , got to the final step, but now I'm stumped. What make target should I choose? 'make full_x86-eng' and 'make generic_x86' have no make rules. A simple 'make' generates a framework build error.
What do I have to do in order to get a bootable image (built from source) for the Razr i?
I'd appreciate any kind of advice. Thanks in advance.
PS: Many thanks Matt, turl1 and the other developers that worked on this device.

You won't be able to build a full android system from that source. The most you can do is
Code:
$ . build/envsetup.sh
$ lunch generic_x86-eng
$ make [I]target[/I]
Where target is something like out/target/product/generic/system/bin/bluetoothd or bluetoothd
I am working on a device tree. Writing it from scratch isn't easy because there is no device I can base this on. No other x86 tree out there. And I still dont have a device. I did make threads requesting for a device but they got closed down. So once I have something built I'll make a new thread.

There's at least 10 device trees on the android-x86 project. And AOSP itself has a generic one, to build the x86 emulator platform. And I made a basic one to build recovery already, with support to generate the newer x86 boot image format.
Just saying

Generic x86 and the razr I are too far apart. Also the android x86 ones are too far apart too (I am working on a android x86 tablet). I have already written more than 450 lines of the device tree by hand, and there is a lot more to go right now. I have patched bionic for x86 builds, I need to patch the build folder next, and even busybox needs patching, etc. I am now working on making a perfect set of the 3 important files, BoardConfing.mk, device.mk and proprietary-files.txt. My android x86 tree is a total of 181 lines (which in itself is twice the size of the trees on android-x86). Its fun, but really time consuming. Also the AOSP ones are generic ones, they will work on any system if you have all the correct drivers installed or compiled via the kernel, but Razr I needs the files to be pulled from the stock build, and it needs a lot of them, including kernel drivers.

I'm playing a bit with AOSP 4.2 as I got some free time. This is what I found out so far:
bionic needed no patches. I seriously doubt it needs any on 4.1 (CM) either as recovery built fine.
build needed no patches either on both cases.
dalvik needed a 4-liner to build on AOSP (makefile fixes), I haven't tried to build it on CM
there's no busybox on AOSP, I patched the one on 4.1 already to be able to build recovery, it's all on CM Gerrit as you'd expect from a CM developer like myself
my tree is already 120 lines, as soon as you add the media decoder config and audio routing config you'll go over 180 lines
having proper drivers isn't enough, you need proper HALs too. And I haven't really looked, but I'd be surprised if you had to pull kernel drivers from the stock rom

1) bionic needs patching, patch already submitted to CM gerrit libdvm basically
2) build needs patching for the boot.img
3) dalvik has been patched
4) Odd, didn't notice that
5) Probably wont required pulling in kernel drivers, but would required pulling in the correct drivers for the defconfig
I'd be happy if you wanted to work together to get this working. PM me

re. 2, I actually did need to patch build on AOSP after all . CM on the other hand, has BOARD_CUSTOM_BOOTIMG_MK from the tf tablets.
Hey I posted a rom over at droidrzr.com for use till aosp is ready. This should be enough till we get a jb leak

Hi Folks
While I don't own a RAZR I , I have been Jaffing around with building CM10.1 and AOSP for x86, I've been getting in going on my FX8120, just need to sort the OpenGLES MESA drivers out.
Anyways I've got CM10.1 built for x86 using the mr1-staging branch ( I think it's been merged to cm10.1 ) and an edited mini-x86 device tree .
Busybox was a B**stard to build though, although on one of the branches there is an .config-minimal-x86 .config-full-x86, still needed tweaking tho.
I submitted my patches http://review.cyanogenmod.org/#/c/27377/ and http://review.cyanogenmod.org/#/c/27373/, however It seems x86 isn't top of cm's agenda.... or I'm missing something about assigning reviewers.
Obviously a base x86 build is only part of the story for you guys as you'll face all the regular problems that emedded devices have, not checked the specs for the RazR but I'm sure there's some binary blobs in your future,
Hack On Folks! :good:
Hi,
I synced the CM10.1 source last weekend. I mucked about with the kernel. I pointed it to Christopher83's custom toolchain. I built it. It works. I'm content.
However my plan was to revive 4.2.2 and actually ADD to it, otherwise you could just go and download the zip which the Andromadus team uploaded. Unfortunately I've discovered that I'm completely incompetent when it comes to firstly finding things to add, secondly finding the commit, and then thirdly trying to cherry pick and apply the commit so it works. I haven't really got to stage 3 yet.
So here's my suggestion: could someone please work with me or if syncing sources etc. is not possible, at least help me by being knowledgeable enough to know some good features, point me to the commits, and help me fix conflicts so that I can apply them successfully. Therefore I either want a team, the 4.2.2 revival team as it were, or someone or some people to help me if they can't directly interact with the sources. Don't worry if you can't build for whatever reason: if you can sync specific repos, e.g. settings, frameworks base, and modify them, and push them, so that I can build the ROM, that's fine. Anyone who helps at all will be deemed equally if not more important than myself, as I expect I'll ultimately just end up being the builder.
Thanks very much for your support.
I can help you with that. Tell me when you start your project and what errors did you get
Best Regards,
MarcoMarinho

Thanks firstly I thought a simple thing to do would be to add the recent app screen ram bar from SlimBean, but I can't find the commit anywhere in the SlimRoms github. Perhaps you know where it is or can find it for me, then I could cherrypick it and we could fix the conflicts together and we'd have our first unofficial CM10.1 ROM with additional features!

Yep, as you know I synced the CM10.1 source a while ago so I used repo init --reference to sync the PA jellybean-legacy sources. Thanks for helping
paste this in a folder and title it
local_manifests
then add it to your .repo folder in ROM directory
I commented out a few things you may need to add, and there is possibly more but i dont have time to look into it all right now. just start with this, repo sync, and then build and check for errors
best of luck!
damn.... giving me uknown file, had to zip it first, so unzip the contents!

but I can look into this vision.adds business, I don't think it will be necessary as this will place need files in the proper directories in your source code for you, I assume that's what the vision.adds would do?

Here's the bit from their guide: http://forum.xda-developers.com/showpost.php?p=30958881&postcount=2 I'm not sure what it does though. I'm completely clueless about that whole post actually. I think it just syncs stuff after a sync.. or something. I don't know why though, isn't that what a local manifests file is for?
hmm... it looks like there will be a bit more to make than just the local_manifests
but i would attempt this first and if it doesnt work than follow the direction in that post as there me be a special way needed to build for pa, which i never have tried to build
most of what they are after will get pulled from local_manifests folder and placed appropriately. but at the same time... never used ./rom-build.sh before so this may be specific to pa, as in you need to follow their steps....
eh, just give it a try, if it doesnt work ill help you create those json files and build it the way laid out in their guide!

Isn't easy, you need to add more repos to configure it for our phone.
This is very diferent:
http://forum.xda-developers.com/showpost.php?p=45827346&postcount=3467
As I said before, you need extra repos than CM needs. You can talk to the dev that made the SlimBean for our phone, as it's based on AOSP he needed to configure it as well.
Hi guys, long time no post. I have updated this guide on how to build kernels for Falcon so that anyone can learn! It's pretty simple once you get the hang of it. So yeah, here we go!
Prerequisites:
- You must have a Linux firmware running on your computer (I suggest Builduntu because you can skip the next one [build environment setup])
- Build environment setup (Put the this in terminal and follow instructions)
- Patience and a heart willing to learn
- You need to know the languages C, C++, Java, Ruby, Python... NOT! You don't need to know ANY coding languages.
[MOTIVATIONAL SPEECH]
Truth be told, when I first started out developing, I knew NO coding languages except for HTML and a little bit of Java. Both have nothing to do with kernels! I actually learned how to do this when I suffered from a concussion. So if you really want to learn how to kernel dev and you give up halfway, just know that a 14/15 year old kid could do it..

Your Personal Handbook to the Following:
- Anything inside "CODE" boxes, type it into your terminal. If you can't find terminal, then press CTRL, ALT, t.
- If I were you, I would write these by hand instead of copying and pasting it because after a certain amount of times, you will remember the linux commands and it will be easier for you to compile more kernels for different devices
- Use this thread as a "Help Me" button. Ask for help!

A New Beginning:
Let's start out with something simple, getting the actual code:
Code:
git clone https://github.com/cyanogenmod/android_kernel_motorola_msm8226
This could range from 3 minutes to 2 hours!
Once that's done, open up your file manager and rename the folder (should be android_kernel_motorola_msm8226) to whatever you want. I will refer it as "mykernel".

Pokemon!
For this tutorial, we will be using a Sabermod 4.7 toolchain to compile. I WOULD teach you how to compile with 4.8+, but it creates errors that will take even longer for me to write about sooooooooo :fingers-crossed:. Now to get the toolchain:
Code:
git clone https://github.com/SaberMod/android_prebuilts_gcc_linux-x86_arm_sabermod-arm-eabi-4.7
Rename this to whatever you like, but I will be referring this as "toolchain"
Now go into you folder where the kernel source is stored...
Code:
cd mykernel
Click to expand...
Click to collapse
You're Almost There!:
Time to set-up the compiler!
Code:
export CROSS_COMPILE=/home/(insert linux home name here)/toolchain/bin/arm-eabi-
This tells the toolchain that "OK, we want to make ALL this code here into a kernel".
This next line tells it that your defconfig (the toolchain's manual for compiling the kernel) that it's in the arch/arm/configs folder.
Code:
export ARCH=arm
Now to tell the it what the defconfig is!
Code:
make falcon_defconfig
Hehe, now to the hardest part of all...
MuHAHHAHAHa

THE HARD (coding) PART
You ready for this? HERE IT IS! TIME TO BUILD THE KERNEL!
Code:
make -j4
Now sit back, relax, and watch the code! Or you could read a book, watch ****, count your fingers, play with your toes...
If you have an error during the waterfall of code, find the part where it actually says *error* (you'll probably have to scroll upwards) and search it on Google or post it here.

THE BEST PART
If you manage to get something that says "the kernel zImage is ready" or something like that, that means you've made it!
You have officially compiled your own kernel from source! Now you need to put it in a flashable zip.
Download this file and open it up, but DON'T EXTRACT IT.
Now go to your kernel source then "CTRL + F" and search for "zimage-dtb".
Find it and put it in the "kernel" folder of "FalconKernel - Signed.zip". Then "CTRL + F" and search ".ko".
Copy radio-iris-transport.ko and put it in the system/lib/modules (not pronto) of the zip.
Then find wlan.ko and rename it to pronto_wlan.ko. Copy and paste it in system/lib/modules/pronto of the zip.

Now you can put it on your phone and flash it!
I will update this in a bit. What feature would you guys want in your kernel? The most votes in the POLL above will be the one I teach you here!
Here I will walk you through on how to add the intelliplug feature made by @faux123
First, fetch my Green Machine kernel source (go into your kernel folder in terminal):
Code:
git fetch https://github.com/YoshiShaPow/green_machine_falcon
Then you could cherry-pick (basically copy) all my cherry picks for intelliplug from my source.
If you do check my source out, you can see there's a little link to a history of commits near the middle of the screen, right above the files/folders. You can see at this page of my features history, you'll see a bunch of commits for intelliplug. I will use those commits and copy it to your own kernel.
This copies the initial coding/first commit of intelliplug!
Code:
git cherry-pick 01a850f
This cherry-picks the remaining commits so that your newly added intelliplug is updated.
Code:
git cherry-pick 6623f2f^..4e1ece7
One more thing though, you need to add the line to compile intelliplug!
Almost all things compiled along with the zImage are in a file called defconfig. What a defconfig does, is tell your machine to build certain modules, kernel objects, drivers, governors, etc.etc.etc.. Now, all of them are found in the folder
arch/arm/configs
Click to expand...
Click to collapse
As stated in the OP, you have to modify the defconfig you use. (CM11 Kernel is falcon_defconfig, Gummy Kernel is msm8226_mmi_defconfig). Open up the corresponding defconfig and add this to ANY line anywhere.
Code:
CONFIG_INTELLI_PLUG=m
Now, for those who are familiar with "y=yes/n=no/m=maybe", you'll see that I specifically told you to put the "m=maybe" one. That's because when you compile the kernel again, right after you're about to start your build. Since you put that "m", the terminal will prompt you with a "y=yes/n=no" question on whether or not you would like to add the following feature. Since you would like to add the feature, put in "y". Later on when you feel more comfortable with adding features to your kernel, you can go back into the defconfig and put it as
Code:
CONFIG_INTELLI_PLUG=y
So that it will compile it without asking, since you have given it an answer.
Now you have officially compiled a "Custom Kernel" and with the knowledge you know, you could create a feature packed one by just kanging (copying one's work/features).
Always remember to
Code:
make clean && make mrproper
after every build to prevent errors and such!

Any guide on adding governors or hotplug driver??
Sent from my Moto G using XDA Free mobile app
Best guide but how to add features likes s2w,dt2w etc

DT2W and S2W are more complex. They require a few other things (ex. Powersuspend). I'll wait a bit and see what feedback I get before moving forward to something a bit more complex like DT2W, or GPU Overclock.
Can i use make menuconfig?

Yes you can. Normally when using "make menuconfig", you use the command after making the kernel's defconfig (falcon_defconfig).
Build using Docker
If you're on Linux, take a look at this approach which uses Docker for building CyanogenMod 12.0:

When you downloaded the anykernel zip, you aren't supposed to extract it. The best way to put the kernel in the zip is to just drag and drop it while IN LINUX. It will not work for windows! Or you could try signing the zip in TWRP (I think there's an option for that somewhere).

That has nothing to do with this thread :silly:. You probably have to sign the zip again.
@YoshiShaPow.... i need some help
i compile a kernel for my device and it booted fine but no display....
can you help me in this....
sorry for posting here..my device is Redmi 1s

No problem, I welcome anyone with kernel development questions here! When booted, what do you mean? And if there's no display, how do you know it booted? Also, did you use my anykernel zip? I may be wrong but I don't think it is compatible with all phones.

yeah it booted bro....i can hear lock unlock sound and even i can hear incoming call ring
i was trying to fix this from a week and found out it not kernel it rom problem ...
my device is build using prebuilt kernel so any compile kernel wont work...but now they are build with this kernel source so compile kernel work
thanks bro...
and one thing bro... i m new to kernel development so how can i optimize kernel
i know about and can add governors and use custom toolchain but i don't know about o2 or o3 optimization etc and all
sorry if i m being too much
great I start today

Those changes are a bit more advanced because it will bring build errors. The kernel is already preoptimized with o2 changes. The errors are fixable though. I don't think I'll be able to add an explanation for those in this thread, maybe through pm?
