1.安装GCC6

先安装gmp,mpfr,mpc三个包

安装gmp包：

wget https://gmplib.org/download/gmp/gmp-6.1.2.tar.xz
tar xvf gmp-6.1.2.tar.xz
cd gmp-6.1.2
./configure –prefix=/usr/local/gmp
make && make install

安装mpfr包：

wget https://www.mpfr.org/mpfr-current/mpfr-4.1.0.tar.gz
tar xvf mpfr-4.0.1.tar.gz
cd mpfr-4.0.1
./configure –prefix=/usr/local/mpfr –with-gmp=/usr/local/gmp
make && make install

安装mpc包：

wget ftp://ftp.gnu.org/gnu/mpc/mpc-1.0.3.tar.gz
tar xvf mpc-1.0.3.tar.gz
cd mpc-1.0.3
./configure –prefix=/usr/local/mpc –with-gmp=/usr/local/gmp -with-mpfr=/usr/local/mpfr
make && make install

将库文件加入如下文件：

vi /etc/ld.so.conf
增加以下三行
/usr/local/gmp/lib
/usr/local/mpfr/lib
/usr/local/mpc/lib
#
加完后使用如下命令更新
ldconfig -v

源码安装gcc包：

wget ftp://ftp.gnu.org/gnu/gcc/gcc-6.4.0/gcc-6.4.0.tar.gz
tar xvf gcc-6.4.0.tar.gz
./configure –enable-checking=release –enable-languages=c,c++ –disable-multilib –with-gmp=/usr/local/gmp –with-mpfr=/usr/local/mpfr –with-mpc=/usr/local/mpc
make -j2
make install

查看GCC

2.安装glibc2.9

cd /usr/local/
wget http://ftp.gnu.org/gnu/glibc/glibc-2.29.tar.gz
tar -zxvf glibc-2.29.tar.gz

编译出现错误

 设置环境变量

 继续安装

mkdir build
cd build/
../configure --prefix=/usr
make -j2
make install
