编译toolchain arm-linux-gcc 3.3.2脚本解释

khyang

这里给出建立toolchain.3.3.2的脚本(注意，必须先设置内核头文件,如上所述)：
gcc-3.3.2.tar.bz2
glibc-2.3.2.tar.bz2,
binutils-head.tar.bz2,
glibc-linuxthreads-2.3.2.tar.bz2
这里是host:i386,target:arm

#!/bin/sh -e

set -v

build_binutils=yes
build_bootstrap=yes
build_glibc=yes

#  With thanks to erik mouw, jeff sutherland, and many others
