如何在 centos 7.1 上安裝 gcc 5.2?
如何在 centos 7.1 上安裝 gcc 5.2?用 g++,cpp 嗎?
我編譯過一次,但它需要更新的 glibc 不能在系統中切換
你可以從 fedora 創建 repo 並安裝 gcc 5.1.1,它會比編譯它更好。
cat << EOF > /etc/yum.repos.d/Fedora-Core23.repo [warning:fedora] name=fedora mirrorlist=http://mirrors.fedoraproject.org/mirrorlist?repo=fedora-23&arch=$basearch enabled=1 gpgcheck=0 EOF
然後安裝 gcc
yum install gcc --enablerepo=warning:fedora
輸出:
