I am trying to build a kernel for Xperia SP.
First I have git-cloned the kernel source from here:
https://github.com/Tomoms/android_kernel_sony_msm8x60
then git-cloned this toolchain:
https://android.googlesource.com/platform/prebuilts/gcc/linux-x86/arm/arm-eabi-4.7
then I went to:
KERNEL_FOLDER/arch/arm/configs
and copied msm8960_defconfig (as i think Xperia SP has msm8960) to root of KERNEL_FOLDER and renamed it to .config
then I opened the terminal in the KERNEL_FOLDER directory and typed
make ARCH=arm CROSS_COMPILE=~/toolchains/arm-eabi-4.7/bin/arm-eabi-
and got this
CHK include/linux/version.h
CHK include/generated/utsrelease.h
HOSTCC scripts/basic/fixdep
make[1]: `include/generated/mach-types.h' is up to date.
CC kernel/bounds.s
