build common kernel fal

[赵志龙]

I want to build kernel for x86_64, and do as the link https://source.android.com/setup/build/building-kernels tell:

repo init -u https://android.googlesource.com/kernel/manifest -b  common-android11-5.4

repo sync.

BUILD_CONFIG=common/build.config.x86_64 build/build.sh

Then I met this error:

make[1]: Entering directory '/home/....../out/common'

/home/....../common/Makefile:629: include/config/auto.conf: No such file or directory

/home/....../common/Makefile:685: include/config/auto.conf.cmd: No such file or directory

make[1]: x86_64-linux-androidkernel-gcc: Command not found

***

*** Configuration file ".config" not found!

***

*** Please run some configurator (e.g. "make oldconfig" or

*** "make menuconfig" or "make xconfig").

***

/home/....../Makefile:688: recipe for target '.config' failed

make[1]: *** [.config] Error 1

make[1]: Leaving directory '/home/zzl/03_kernel/03_goldfish_kernel-5.4/out/common'

Makefile:179: recipe for target 'sub-make' failed

make: *** [sub-make] Error 2

Does anyone knows what's the reason?

Thanks

Because GCC tool chain as below have removed from android11.

prebuilts/gcc/linux-x86/x86/x86_64-linux-android-4.9/bin/x86_64-linux-androidkernel-gcc

prebuilts/gcc/linux-x86/aarch64/aarch64-linux-android-4.9/bin/aarch64-linux-androidkernel-gcc

you can select one of below ways to fix this issue.

1.  use clang compiler as below which integrated in android11 

prebuilts/clang/host/linux-x86/clang-r383902b/bin

2. use external gcc compiler.

Hi,

The build.config file you selected (common/build.config.x86_64) does not specify any defconfig file.

Unless you have other specific requirements for your target, you should follow the GKI instructions: https://source.android.com/setup/build/building-kernels#building-gki-modules

Cheers,

Alessio
