1. 下载 gcc-6.2.0 源码包，可以直接从 GCC 的FTP 上下载，随后解压

并从 contrib/download_prerequisites 文件内查看需要的依赖包

[root@node1 software]# tar -zvxf gcc-6.2.0.tar.gz

[root@node1 software]# cd gcc-6.2.0/

[root@node1 contrib]# vim contrib/download_prerequisites

下载依赖包

[root@node1 software]# wget ftp://gcc.gnu.org/pub/gcc/infrastructure/mpfr-2.4.2.tar.bz2

[root@node1 software]# wget ftp://gcc.gnu.org/pub/gcc/infrastructure/gmp-4.3.2.tar.bz2

[root@node1 software]# wget ftp://gcc.gnu.org/pub/gcc/infrastructure/mpc-0.8.1.tar.gz

2. 安装 gmp

[root@node1 software]# bzip2 -d gmp-4.3.2.tar.bz2

[root@node1 software]# tar xvf gmp-4.3.2.tar

[root@node1 software]# cd gmp-4.3.2/

[root@node1 gmp-4.3.2]# ./configure --prefix=/opt/gcc-6.2.0

[root@node1 gmp-4.3.2]# make -j  //没问题

[root@node1 gmp-4.3.2]# make check //出错 参考http://www.linuxdiyf.com/linux/26770.html

3. 安装 mpfr

[root@node1 gmp-4.3.2]# cd ..

[root@node1 software]# bzip2 -d mpfr-2.4.2.tar.bz2

[root@node1 software]# tar xvf mpfr-2.4.2.tar

[root@node1 software]# cd mpfr-2.4.2/

[root@node1 mpfr-2.4.2]# ./configure --prefix=/opt/gcc-6.2.0

[root@node1 mpfr-2.4.2]# ./configure --prefix=/opt/gcc-6.2.0 --with-gmp=/opt/gcc-6.2.0
