目前，我尝试使用Cross Linux from Scratch 中的说明从头开始构建嵌入式 Linux 。
一切正常，直到我尝试编译 GCC 交叉编译器。我想为 Beagleboard-xM 构建 Linux...所以我选择了以下设置：
export CLFS_ABI="aapcs-linux"
export CLFS_HOST="x86_64-cross-linux-gnu"
export CLFS_TARGET="armv7a-unknown-linux-uclibceabi"
export CLFS_ARCH="arm"
export CLFS_ENDIAN="little"
export CLFS_ARM_ARCH="armv7"
export CLFS_ARM_MODE="arm"
export CLFS_FLOAT="hard"
export CLFS_FPU="neon"
不，只要我尝试运行此页面上的说明，命令就会make all-gcc all-target-libgcc出错。
