Note2 Kernel building tutorial [Dump] [Draft-Alpha 0.0.1]

November 14, 2012 by ·

First get the defconfig:

ls -l ./arch/arm/configs[/code] 


-t0_04_defconfig


So,


cp arch/arm/configs/t0_04_defconfig ./.config[/code] 


Once that's done, execute:


make oldconfig


Now a new .config file is written to kernel root


Now you can execute a make, only to find that it errors out soon. The reason is of course a "-Werror" parameter in the main Makefile, which you can see if you do a:


grep -i -n '-Werror' Makefile[/code] 


So, edit the file in emacs, and remove the -Werror


It didnt still build and gave an error of the compiler not supporting arm


So downloaded the latest NDK android-ndk-r8c


 wget http://dl.google.com/android/ndk/android-ndk-r8c-linux-x86.tar.bz2


Added the toolchain to $PATH, chose the toolchain, and hey presto! The kernel compiled without any errors! 😀 😀
