gcc-4.8.2.tar.gz，解压到gcc-4.8.2目录。

snippet.bash

./contrib/download_prerequisites

下载依赖包。

如果不能联网，在实现将以下文件放入gcc-4.8.2目录下：

• mpfr-2.4.2.tar.bz2
• gmp-4.3.2.tar.bz2
• mpc-0.8.1.tar.gz

snippet.bash

vi ./contrib/download_prerequisites

snippet.bash

sudo yum install glibc-devel.i686 libstdc++-devel.i686

否则编译阶段会报以下error：

usr/include/gnu/stubs.h:7:27: fatal error: gnu/stubs-32.h: No such file or directory

snippet.bash

./configure
make -j8
sudo make install
