Source code for these libraries can be found at their respective hosting sites as well as at ftp://gcc.gnu.org/pub/gcc/infrastructure/. See also http://gcc.gnu.org/install/prerequisites.html for additional info. If you obtained GMP, MPFR and/or MPC from a vendor distribution package, make sure that you have installed both the libraries and the header files.

2、安装依赖包
cd /usr/local/src/gcc-9.5.0
vi ./contrib/download_prerequisites
下面红框是需要手动下载的依赖包
wget https://gcc.gnu.org/pub/gcc/infrastructure/isl-0.18.tar.bz2 --no-check-certificate
tar -xjvf isl-0.18.tar.bz2
ln -s isl-0.18 isl
在https://mirrors.sjtug.sjtu.edu.cn/gnu/下载 mpc-1.0.3.tar.gz
mpfr-3.1.4.tar.bz2 gmp-6.1.0.tar.bz2
tar -xvfz mpc-1.0.3.tar.gz
ln -s mpc-1.0.3 mpc
tar -xvfj gmp-6.1.0.tar.bz2
ln -s gmp-6.1.0 gmp
tar -xvfj mpfr-3.1.4.tar.bz2
ln -s mpfr-3.1.4 mpfr
3、再次配置安装目录

4、配置支持语言 C C++
./configure --prefix=/usr/local/gcc-build-9.5.0/ --disable-multilib --enable-checking=release --enable-languages=c,c++
这步会生成makefile文件，供make命令使用。

5、编译源码
需要提前安装依赖包，否则会编译失败
apt-get install build-essential
apt-get install g++
cd /usr/local/src/gcc-9.5.0
make
注：编译时间很长
Makefile文件巨长 1.1M 29377行
花费了3个小时编译完成，机器配置：内存8G CPU 1核
6、安装程序
6.1、make install
安装好成功后有如下提示。
6.2、查看gcc版本
