总体安装步骤大同小异，详细步骤请参考下述链接：

OLLVM环境搭建-编译x86指令集可执行程序-Ubuntu 20.04跟着铁头干混淆2 ubuntu20.04编译ollvm cmake报错

obfuscator/cmake/config.guess: 71: Syntax error: word unexpected (expecting "in")

经过查阅相关类似问题的解决方案，如cmake增加-DLLVM_INCLUDE_TESTS=OFF选项等，均不奏效。最终在StackOverFlow上面一位网友提供的解决方案成功的解决了此问题，主要的原因是在config.guess文件中存在一些DOS行结尾(DOS line endings)，需要将其转换为Unix行结尾。

sudo apt-get install dos2unix
dos2unix path/to/config.guess

从头再来即可成功编译OLLVM
