Help with zImage kernel compilation - Android Q&A, Help & Troubleshooting

This is my first time trying to compile my own kernel, i am dealing some problems and need help
i get these messages when executing the commang "make"
CHK include/linux/version.h
SYMLINK include/asm -> include/asm-arm
make[1]: `include/asm-arm/mach-types.h' is up to date.
CHK include/linux/utsrelease.h

http://hertaville.com/2012/09/28/development-environment-raspberry-pi-cross-compiler/
i am running ubuntu 14.04 lts 64 bit. i am trying to compile kernel 2.6.32 for s3c6410. old chipset but even if brick it i do not care much
any help ?

Which toolchain and version of the toolchain are you using? I would recommend checking out this information on someone who ran into the same problem as you and how they fixed it. Let me know if you still have questions.

i am using toolchain arm-eabi 4.6
i red the documentation
i have nothing like <<cc1>> under usr/bin
I don't have a /usr/local/libexec directory
i installed anything about cc1 from package manager and still nothing changed.
i did something wrong with <<make menuconfig>> or else ?
i also follow this guide https://github.com/argentinos/o2droid/tree/i8000/kern_2.6.32
i use the wrong toolchain ?

If you follow the guide in the repository that is meant for a pure Linux kernel, what def config under arch/arm/configs did you use?
Try using a procedure similar to the following:
Code:
export TOP= [where you installed the toolchain or top of android AOSP code base]
export PATH=$TOP/prebuilts/gcc/linux-x86/arm/arm-eabi-4.6/bin:$PATH (use corresponding arm-eabi bin path)
export ARCH=arm
export SUBARCH=arm
export CROSS_COMPILE=arm-eabi-
make NAMEOFDEVICE_defconfig
make -jx (Where x is the number of jobs you want -j4 is a safe option)

i followed your commands and no result yet. same problems

upd... i am searching and testing possible solutions, but nothing is working. i stuck on this mistake. cc1 exists on my pc and is executable. i also tried another toolchain 4.4.3 which is considered more compatible, but stuck on the same error again. really driving me crazy. i have too much job to do on the kernel improvement, but if i will never be able to compile it it doasn't worth trying. i appreciate your help. any ideas ?

After looking more into it I noticed there is a script included in the files for building the kernel called make_kernel, you should be able to build the kernel running the script, "./make_kernel -k" with the -k option being defined by the script to make the kernel. You may have to tweak the script to suite your build environment.

thanks a lot. i did run the script many times, with many ways. i see some compilation being done, but i always after a few minutes i end with the message "Error ... kernel not compiled!"
i guess some code errors cause it, but how to locate them and fix them under millions of programming lines ?
i red that before being able to compile a kernel and before this kernle is funtional you must fix many errors and deal many problems, but i am not sure how difficult this is going to be in my case.
i always get messages of this type " warning: variable ‘*’ set but not used [-Wunused-but-set-variable]
"
you follow any specific procedure to deal with these errors ?

In the error messages you will see what file the error is in and which line the error occurs going to that file and line(s) the error occurred at is the best place to start. Instead of using the script take the commands in the script and do them manually in the order the script would execute them in, until you get an error you can troubleshoot or it compiles successfully.
