1、下载依赖包

编译安装 GCC 需要依赖 mpc，mpfr，gmp包。好在 GCC 源码里自带脚本可以轻松下载依赖包。

./contrib/download_prerequisites

2、编译安装

mkdir build;cd build

../configure --prefix=/home/mrc/.software/gcc/gcc-installpath-6.4.0/

第一次出现了如下错误：

configure: error: I suspect your system does not have 32-bit development libraries (libc and headers). If you have them, rerun configure with --enable-multilib. If you do not have them, and want to build a 64-bit-only compiler, rerun configure with --disable-multilib.

于是

../configure --prefix=/home/mrc/.software/gcc/gcc-installpath-6.4.0/ --disable-multilib

成功执行configure

make -j 8    #编译过程 巨长

make install
