Hi, Hikey 960 experts,
I’m following this guide (Using Reference Boards | Android Open Source Project) to build kernel 4.14 for Hikey960. Everything goes fine and the new kernel can successfully run.
However, when compiling the kernel, it constantly warns me that Android GCC has been deprecated in favor of Clang, and will be removed from Android in 2020-01.
I wonder if hikey-linaro is able to be build by Clang. If so, do you have a guide? Thanks!
The build instructions still use gcc. I think that the snapshot builds are using clang.
This is what I use;
#!/bin/bash
AOSP_ROOT={set this as appropriate}
mPATH=$AOSP_ROOT/prebuilts/clang/host/linux-x86/clang-r353983c/bin:$AOSP_ROOT/prebuilts/gcc/linux-x86/aarch64/aarch64-linux-android-4.9/bin
PATH=$mPATH:$PATH make ARCH=arm64 hikey960_defconfig
PATH=$mPATH:$PATH make ARCH=arm64 CC=clang CLANG_TRIPLE=aarch64-linux-gnu- CROSS_COMPILE=aarch64-linux-android- -j$(nproc)
Thank you! This works for me
Thank you! This works for me. i think the resolution should tell all the people who build the hikey960 kernel.
also resolve the problem" aarch64-linux-android-gcc: Command not found"
and “Android GCC has been deprecated in favor of Clang, and will be removed from
Android in 2020-01 as per the deprecation plan in:
Android GCC 4.9 Deprecation Schedule”
Hi,
I inquired internally and my colleague gave me the suggestion for the Clang version is updated to clang-r377782b [1].
So following @doitright script (excellent!), below is the updated one:
#!/bin/bash
AOSP_ROOT={set this as appropriate}
CLANG_VERSION=r377782b
mPATH=$AOSP_ROOT/prebuilts/clang/host/linux-x86/clang-$CLANG_VERSION/bin:$AOSP_ROOT/prebuilts/gcc/linux-x86/aarch64/aarch64-linux-android-4.9/bin
PATH=$mPATH:$PATH make ARCH=arm64 hikey960_defconfig
PATH=$mPATH:$PATH make ARCH=arm64 CC=clang CLANG_TRIPLE=aarch64-linux-gnu- CROSS_COMPILE=aarch64-linux-android- -j$(nproc) Image.gz dtbs
I’d like sync internally and check if can update the Android device page for the building steps [2].
Thanks!
