[9270...@qq.com]

i put below: 

export ARCH=arm64 

export CROSS_COMPILE_ARM32=aarch64-linux-android- 

PATH=/home/shallin/android9_r22/prebuilts/gcc/linux-x86/aarch64/aarch64-linux-android-4.9/bin:$PATH make wahoo_defconfig and then i put "make" ,show like this 

how can i do

Hi,

That is not the right procedure to build Wahoo kernels: as the documentation says, that is an example for HiKey development boards.

Please have a look at our recently updated Building Kernels documentation, which shows a much simpler out-of-the-box procedure to build custom kernels: https://source.android.com/setup/build/building-kernels.

Regards,

Alessio

Check your build.config file in kernel. So it has what needed config directories and files.

LZ4_PREBUILTS_BIN=prebuilts-master/misc/linux-x86/lz4

DTC_PREBUILTS_BIN=prebuilts-master/misc/linux-x86/dtc

LIBUFDT_PREBUILTS_BIN=prebuilts-master/misc/linux-x86/libufdt

Download this lz4(Compression algorithm),dtc(Device Tree compiler),libufdt(Used for optimization of dtos)

and give proper path and config and use CC=clang. Coz pixel 2 user level programms are compiled using clang. So some of the files will be compile using Clang.

export ARCH=arm64

export CROSS_COMPILE_ARM32=~/PATH_TO_directory(arm eabi 4.7 or 4.8)/arm-eabi-

export CROSS_COMPILE=~/PATH_TO_DIR(aarch64)/....

LZ4_PREBUILTS_BIN=prebuilts-master/misc/linux-x86/lz4

DTC_PREBUILTS_BIN=~/pATH TO/linux-x86/dtc

LIBUFDT_PREBUILTS_BIN=`/pATH_TO_DIR/linux-x86/libufdt
