编译Android内核时执行格式错误

Question

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

    make[1]: `include/generated/mach-types.h' is up to date.

Answer 1

People used to get this error when building on 32bit systems. Ensure you are building on 64bit linux.
