Cross Compile Android (Mako) Kernel with Linaro Toolchain

问题

i successfully compiled and boot my own kernel with this tips:

http://astro.temple.edu/~tue68607/project/articles/customized-android-aospsystem-nexus4.html

so now I wanted to use Linaro toolchain.

I tested setting path with the Google's method but can't work. I got this error

Is your PATH set correctly?
make[2]: *** [scripts/mod/empty.o] Error 2

I already set the path correct to point here:

/home/najmi/android/toolchain/linaro-git/android-toolchain-eabi/arm-linux-androideabi/bin

Obviously, as the error said

arm-linux-androideabi-gcc: No such file or directory

This means that the current version of NDK that your are using dose not conatin gcc. So,try an older version of android NDK(I suggest version 15c which contains gcc). https://developer.android.com/ndk/downloads/older_releases.html

Then, try the following in the same order :

$ export ARCH=arm
$ export CROSS_COMPILE=<your path >/android-ndk-r15c/toolchains/arm-linux-androideabi-4.9/prebuilt/linux-x86_64/bin/arm-linux-androideabi-
$ make mako_defconfig
$ make -j4

make sure to run the following code to clean any previous compilation before running compile anything. if you didn't compile anything. then no need to run this code

$ make clean && make mrproper

I've tested before and its work.
