. 先下载gcc11源码包并解压:
wget https://gcc.gnu.org/pub/gcc/releases/gcc-11.2.0/gcc-11.2.0.tar.gz
tar -zxf gcc-11.2.0.tar.gz
. 准备依赖.
cd gcc-11.2.0
./contrib/download_prerequisites
. 配置
./configure --prefix=/usr/local/gcc11 --enable-bootstrap --enable-languages=c,c++ --enable-threads=posix --enable-checking=release --enable-multilib --with-system-zlib
. 编译 根据自己cpu核心调整 - j参数
make -j24
. 安装
make install
