In your Wiki here: http://docs.omnirom.org/Setting_Up_A_Compile_Environment you're talking about 32bit systems. AFAIK compiling on 32bit is not possible anymore. Despite that you'll get a 64bit linux-androideabi-4.7 if you sync sources. Is compiling on 32bit possible again ? If not, you should perhaps update your Wiki...

Google have not supported compiling Android on 32-bit x86 machines for well over a year, but it was possible to build cm-10 (the last time I tried it) providing you had the correct toolchain - see for example
Code:
https://github.com/yath/android_prebuilts_gcc_linux-x86-32_arm_arm-linux-androideabi-4.6
Despite this, I think you are right about the Wiki needing corecting.

Hey all. This is my first post here on XDA.
I've been thinking of compiling my own kernel image for my HTC Legend. I've spent hours googling and reading different forums and blog's. But without greater success, most of the guidelines are not spot on and some things are not cristal. So I have a few questions regarding this.
I have read that a specific radio image is just "comptabile" for compilation with a specific kernel version. So let's say I have HTC_LEGEND_RADIO_7_083521_sign.zip, how do I know what kernel version this is made for? In my ears this sounds pretty strange . I would not be able to build a kernel from that radio image and the 2.6.35.5 Linux kernel?
I've also tried to figure out what exactly the radio image is from various boguos posts on different forums, and what I belive it is from the tiny bits of information I've found is that It's modules for the phones hardware?
Oh, and what is the latest radio image version available for the HTC Legend?
Hope someone can help me clear some of my questions
I can only answer the very last question lol, it's 7.08.35.21
Latest RUU:
RUU_Legend_Vodafone_AU_2.10.178.1_Radio_47.39.35.09_7.08.35.21_release_138238_signed.exe

Hi tonper,
First... where did you get that radio has something to do with kernel??? Radio image is basically a firmware (operating system of its own that interacts with radio hw) and has nothing to do with Android kernel which is in fact patched Linux kernel. One can access all functions of radio through userspace Android apps that communicate with radio via native libraries. That's all that it is to say about radio in conjunction with kernel.
To be able to build a kernel one should first master basics of Unix/Linux system principles and first try to build own kernel for some Linux distro. One need to know also how to boot this kernel and use it with the rest of the operating system. Last thing to master is cross-compiling as you will be building kernel for ARM architecture most possibly on your x86 PC. In short the topics to search for would be:
* knowing Linux (principles)
* booting Linux (process)
* compiling Linux kernel
* cross-compiling
Android powah!
Thanks for your answer BlaY0!
Will check into it some more this weekend with this new information.

Been running Linux for 10 years and Debian for 7 years. So got the basic knowledge I just can't find any good documentation on this topic
Cyanogenmod wiki have some guides

How could I have missed that page? Have been googling like a maniac. That was pretty much exactly what I was looking for. Thanks alot snake

OK, then you're set m8 you just need to grab some ARM cross-compiling toolchain for x86. Your first bet would be Android NDK. You can also use CodeSourcery or even build your own toolchain with Buildroot... but for compiling kernel really doesn't matter which one U use.
Happy compiling
Here is an update to 'agcc' wrapper originally written by Andrew Ross. You can find his original version here.
Modded/Updated agcc
Helps you to quickly compile native C code for ARM, MIPS or x86 targets. I updated 'agcc' to try out a few existing exploits on Android, in hope of finding a few more to open up root for my new phone.
I thought some of you may find this updated script useful for compiling native code. I have tested these changes only on a Windows machine using Android NDK r8b.

I just searched ebay for RK3066 Development Board, and found one there, I have played the Beagle board.
this one seem good for play with RK3066 firmware and debug rom.

Not used that one, but I'd caution you away from the RK3066 in general, as I have used a device with RK3066 chipset...
Rockchip don't respect or follow the GPL and give sources with binaries included. This means you cannot compile entirely from source, and can be problematic. Some core drivers like the clock driver are blobbed.
There may be better development boards out there, the ODroid X2 is one I've heard good things about.
I have checked the Latest Linux Kernel source from Kernel.org, all their source code included, using new ARM DTS system (device tree source), so you can compile all your kernel directly from mainstream kernel, except some board level chip driver, which you need to customize from Driver fold, /linux/arch/arm/boot/dts/rk3066a.dtsi, rk3066a-clocks.dtsi

Have you got NAND drivers for the rk3066 nand? clock drivers, ddr drivers?
(see files with a .uu extension, it's a uuencoded .o binary)
https://github.com/AndrewDB/rk3066-kernel/tree/master/arch/arm/mach-rk30 (ddr.uu, ddr_freq.uu, clock_data.uu)
https://github.com/AndrewDB/rk3066-kernel/tree/master/drivers/video (fb.uu)
I believe there's also some missing drivers for the nand (https://github.com/AndrewDB/rk3066-kernel/tree/master/drivers/mtd/rknand)
I just got the development broad from ebay and checked the source code, it do missing these source file and although you can build the kernel without issue for 3.0.8.
I believe the latest 3.10.x kernel from kernel org, which included the RK3066 DTS files, can be used to build the generic kernel that can run on RK3066 board and should have no other source code needed.
I'm trying to build this kernel based on 3.10.x, anyone know detail steps that build the generic kernel based on RK3066 DTS?
Thank advance.
Source code here:
https://code.google.com/p/jscripts/source/browse/#svn/trunk/MortScript
MortScript currently only exists as a 32-bit version, it's development has been stopped years ago. Most today's computers are 64-bit, so it would be great to have a 64-bit version of MortScript, too.
Hello,
For those interested in the original kernel source code for the SM-T813 :
As I am learning how to make ports for Android, I am trying to train on the original sources of the Linux kernel for the SM-T813.
After several weeks of research, I couldn't find the origin of the different kernel repositories.
Also on https://opensource.samsung.com, it was impossible to find the sources. So I contact them at the end of January to have an access to this sources...
... And they are now available !
You can download them on https://opensource.samsung.com (search SM-T813 at mobile phone on release center) or on my repository at https://github.com/Akipe/android_kernel_samsung_gts210vewifi_original_samsung
It is based on the T813XXS2BTK3 firmware with Android 7 Nougat.
I will see to ask for sources of similar tablets.
Will this help with porting new Adnoid version to these tablets?

I don't think so,
Kernel sources for this tablet already exist, and are ported to newer versions.
It is more useful for those who want start from scratch, and want to inspect the unmodified source code.
But my goal would be to successfully create from scratch for the SM-T813 LineageOS 14.1 (Android 7); and then try to move to the latest versions.
Since I am a beginner, I still have a lot to learn, and I don't have much time, so we will see
