Remember to upgrade gcc to 9.3.0 under CentOS7

background

Recently I have to compile and install graph-tool, so I have to upgrade gcc from 4.8 to 9.3, because gcc9.1 and later support C++2017

method

1. Download the source code package https://mirrors.aliyun.com/gnu/gcc/gcc-9.3.0/

2. Unzip and cut into the directory

[root@scentos DynamicGraph]# tar -zxvf gcc-9.3.0.tar.gz

[root@scentos DynamicGraph]# cd  gcc-9.3.0/

3. Download required dependencies

[root@scentos gcc-9.3.0]# ./contrib/download_prerequisites

[root@scentos gcc-9.3.0]#  yum install glibc-devel.i686 libstdc++-devel.i686

4. Compile and install

[root@scentos gcc-9.3.0]# ./configure --prefix=/usr --enable-multilib

[root@scentos gcc-9.3.0]# make

[root@scentos gcc-9.3.0]# make install

5. Verification

[root@scentos gcc-9.3.0]# gcc --version

Conclusion

If downloading from the official website is slow, you can download it from my network disk:
