先按INSTALL.md安装好需要的库
我用的kali 2021，自带有llvm 9 11 12，所以就没再安装了，不过建议还是准备个新环境，按文档全部装上
然后测试的过程发现出现了[-] Oops, can't find gcc header files. Be sure to install 'gcc-X-plugin-dev'.也就是要安装gcc对应版本的plugin-dev，这个在文档也有体现，就是下面的命令安装的，可以自己识别出来对应的版本。当然这里也安装了libstdc++-X-dev
sudo apt update
sudo apt install -y gcc-$(gcc --version|head -n1|sed 's/\..*//'|sed 's/.* //')-plugin-dev libstdc++-$(gcc --version|head -n1|sed 's/\..*//'|sed 's/.* //')-dev然后设置好LLVM_CONFIG环境变量，因为后面会用到。似乎12更好些，不过稳妥起见，这里设置成11的
export LLVM_CONFIG="llvm-config-11"然后就可以开始编译了，安装的时候需要用sudo，然后会用到LLVM_CONFIG，于是使用-E来保持环境变量
make
sudo -E make install不出意外就是下面这样了，算是完成了编译
