如题, CentOS编译装置时可能提醒以下谬误, 须要降级GCC版本
configure: error: Your compiler does not have the necessary C++17 support! Cannot proceed.
执行命令:
yum install -y centos-release-sclyum install devtoolset-8-gcc*
实现后执行:
切换以后会话中gcc版本为8
scl enable devtoolset-8 bash
或者:
间接替换旧的gcc
mv /usr/bin/gcc /usr/bin/gcc-4.8.5ln -s /opt/rh/devtoolset-8/root/bin/gcc /usr/bin/gccmv /usr/bin/g++ /usr/bin/g++-4.8.5ln -s /opt/rh/devtoolset-8/root/bin/g++ /usr/bin/g++
执行命令查看版本:
gcc -v
