編譯android 3.10內核源碼時出錯

最近我嘗試爲我的xiaomi mi4c交叉編譯android內核。要做到這一點，我已經下載並這樣配置的工具鏈：從這裏編譯android 3.10內核源碼時出錯

git clone https://android.googlesource.com/platform/prebuilts/gcc/linux-x86/aarch64/aarch64-linux-android-4.9 -b marshmallow-release toolchain64 
export ARCH=arm64 
export SUBARCH=arm64 
export CROSS_COMPILE=`pwd`/toolchain64/bin/aarch64-linux-android-

然後我克隆內核源代碼：https://github.com/AndropaX/android_kernel_xiaomi_msm8992

，並做到這一點：

make clean && make mrproper 
make ARCH=arm64 resurrection_libra_defconfig 
make ARCH=arm64 CROSS_COMPILE=$CROSS_COMPILE -j3

然後，我有一個錯誤：

所以，問題是，我在做什麼錯誤？也許我需要另一個用於交叉編譯的工具鏈？ Sombody可以提供一個嗎？我不認爲在內核代碼中有錯誤。那麼會出現什麼問題呢？

它可能不會有所作爲，但你的shell輸入是標新立異。（1）由於您導出了ARCH和CROSS_COMPILE env變量，因此您不必在** make **命令中再次指定它們。（2）CROSS_COMPILE僅僅是命令前綴，而不是整個路徑。修改env變量PATH以包含您的工具鏈。（3）'make mrproper'使前面的'make clean'成爲多餘的。（4）嘗試沒有'-j3'選項的構建。 IIRC偶爾出現並行工作問題。 – sawdust

這看起來像是同樣的問題：https：//github.com/MiCode/Xiaomi_Kernel_OpenSource/issues/14 – sawdust

因此，幾天後我找到了答案。感謝4pda的kay2777。

查找在主Makefile中KBUILD_CFLAGS，並添加以下壓制警告視爲錯誤：

KBUILD_CFLAGS += -w 
// if all errors are to be suppressed 

KBUILD_CFLAGS += -Wno-error=unused-but-set-variable 
// if that specific error is to be suppressed.
