yum install scl-utils
# 查询软件集合
yum list all --enablerepocentos-sclo-rh | grep devtoolset
# 安装gcc 7 版本
yum install devtoolset-7-toolchain
# 列出所有软件
scl --list
# 切换软件环境
scl enable devtoolset-7 bash yum install gcc-toolset-11
切换GCC版本
scl enable gcc-toolset-11 bash 仅将.repo中源替换为阿里云或国内其它的源不能解决问题。于是使用了vault源
以下以centos7.4为例其它的7.3 7.6等则需要将7.4.1708改为相应的。
