非root权限配置gcc

gcc下载网址：

Index of /gnu/gcc/ | 清华大学开源软件镜像站 | Tsinghua Open Source Mirror

tar解压，然后打开./contrib/download_prerequisites

可以看到三个依赖gmp,mpfr,mpc的要求版本。

依赖下载网站：

Index of /pub/gcc/infrastructure (gnu.org)

三个依赖的安装顺序：

gmp->mpfr->mpc

分别解压，然后依次：

gmp:
./configure --prefix=/home/zjw/environment/gmp
mpfr
./configure --prefix=/home/zjw/environment/mpfr --with-gmp=/home/zjw/environment/gmp/
mpc
./configure --prefix=/home/zjw/environment/mpc --with-gmp=/home/zjw/environment/gmp/ --with-mpfr=/home/zjw/environment/mpfr/

然后加入到环境变量中

安装gcc:
./configure --prefix=/home/zjw/environment/gcc --enable-threads=posix --disable-checking --enable-language=c,c++ --disable-multilib --with-gmp=/home/zjw/environment/gmp/ --with-mpfr=/home/zjw/environment/mpfr/ --with-mpc=/home/zjw/environment/mpc/

gcc的环境变量如下：

export PATH=/home/zjw/environment/gcc/bin:/home/zjw/environment/gcc/lib64:$PATH
export LD_LIBRARY_PATH=/home/zjw/environment/gcc/lib/:$LD_LIBRARY_PATH
export LD_LIBRARY_PATH=/home/zjw/environment/gcc/lib64/:$LD_LIBRARY_PATH
