ARM交叉编译环境

1. 建立一个linux编译环境，我选的是Fedora 14。

本文所有操作都在root用户执行。

2. 交叉编译环境建立：

拷贝arm-2010.09-51-arm-none-eabi-i686-pc-linux-gnu.tar.bz2到Fedora14的/root/目录：

# cd /root/

# mkdir maxshu

# tar -jxvf arm-2010.09-51-arm-none-eabi-i686-pc-linux-gnu.tar.bz2 -C maxshu/

# vi .bash_profile

     PATH=/root/maxshu/arm-2010.09/bin/:$PATH:$HOME/bin

# . .bash_profile

# arm-none-eabi-gcc -v

Using built-in specs.

COLLECT_GCC=arm-none-eabi-gcc

COLLECT_LTO_WRAPPER=/root/maxshu/arm-2010.09/bin/../libexec/gcc/arm-none-eabi/4.5.1/lto-wrapper
