CentOS upgrade GCC

使用 SCL 安裝方式,它不會取代原本系統的 gcc ,是透過 sch enable 進行切換,相對比較安全

以 gcc 9 為例:
yum -y install centos-release-scl-rh
yum -y install devtoolset-9-toolchain.x86_64

# which gcc
/usr/bin/gcc
# gcc --version
gcc (GCC) 4.8.5 20150623 (Red Hat 4.8.5-44)

切換到 gcc 9 的環境

# scl enable devtoolset-9 bash
# which gcc
/opt/rh/devtoolset-9/root/usr/bin/gcc
# gcc --version
gcc (GCC) 9.3.1 20200408 (Red Hat 9.3.1-2)
