GCC - 14.2.0 安装使用（WSL）

前几天想着换 GCC 版本，编译完发现没法用（缺少 GLIBCXX-3.4.32）研究了一下

编译安装

下载源码 gcc-14.2.0.tar.gz

解压

1
tar -xvf ./gcc-14.2.0.tar.gz

你可能需要先安装 build-essentials 等编译环境

1
2
sudo apt install build-essential -y
sudo apt install libmpfr-dev libgmp3-dev libmpc-dev -y

随后进入目录，进行编译

cd ./gcc-14.2.0
./configure -v --build=x86_64-linux-gnu --host=x86_64-linux-gnu --target=x86_64-linux-gnu --prefix=/usr/local/gcc-14.2.0 --enable-checking=release --enable-languages=c,c++ --disable-multilib --program-suffix=-14.2.0
make -j
sudo make install

切换 GCC 版本

推荐使用 config

1
2
sudo update-alternatives --config gcc
sudo update-alternatives --config g++

解决缺少 GLIBCXX-3.4.32 的问题

sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt update
sudo apt install libstdc++6
