安装clang
For convenience there is an automatic installation script available that installs LLVM for you. To install the latest stable version: bash -c "$(wget -O - https://apt.llvm.org/llvm.sh)" To install a specific version of LLVM: wget https://apt.llvm.org/llvm.sh chmod +x llvm.sh sudo ./llvm.sh <version number> To install all apt.llvm.org packages at once: wget https://apt.llvm.org/llvm.sh chmod +x llvm.sh sudo ./llvm.sh <version number> all # or sudo ./llvm.sh all
比如安装14：
sudo ./llvm.sh 14 all
安装完毕后，可以使用update-alternatives配置一下：
sudo update-alternatives --install /usr/bin/clang clang /usr/bin/clang-10 50 --slave /usr/bin/clang++ clang++ /usr/bin/clang++-10 --slave /usr/bin/clang-cpp clang-cpp /usr/bin/clang-cpp-10 sudo update-alternatives --install /usr/bin/clang clang /usr/bin/clang-14 100 --slave /usr/bin/clang++ clang++ /usr/bin/clang++-14 --slave /usr/bin/clang-cpp clang-cpp /usr/bin/clang-cpp-14 sudo update-alternatives --install /usr/bin/clang clang /usr/bin/clang-17 200 --slave /usr/bin/clang++ clang++ /usr/bin/clang++-17 --slave /usr/bin/clang-cpp clang-cpp /usr/bin/clang-cpp-17
编译内核
比如按照前面的步骤按照了clang，版本是17，那么可以使用下面的命令编译：
make LLVM=-17
