最近我尝试为我的xiaomi mi4c交叉编译android内核。 要做到这一点，我已经下载并这样配置的工具链：从这里编译android 3.10内核源码时出错

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-

，并做到这一点：

make clean && make mrproper

make ARCH=arm64 resurrection_libra_defconfig

make ARCH=arm64 CROSS_COMPILE=$CROSS_COMPILE -j3

然后，我有一个错误：

所以，问题是，我在做什么错误？也许我需要另一个用于交叉编译的工具链？ Sombody可以提供一个吗？我不认为在内核代码中有错误。那么会出现什么问题呢？

它可能不会有所作为，但你的shell输入是标新立异。 (1)由于您导出了ARCH和CROSS_COMPILE env变量，因此您不必在** make **命令中再次指定它们。 (2)CROSS_COMPILE仅仅是命令前缀，而不是整个路径。修改env变量PATH以包含您的工具链。 (3)'make mrproper'使前面的'make clean'成为多余的。 (4)尝试没有'-j3'选项的构建。 IIRC偶尔出现并行工作问题。 –

这看起来像是同样的问题：https：//github.com/MiCode/Xiaomi_Kernel_OpenSource/issues/14 –
