编辑一个批处理文件如下： set MINGW_HOME=D:\CodeBlocks20161122\LLVM set MINGW_VERSION=4.9.1 set "PATH=%MINGW_HOME%\bin;%PATH%" set SS=i686-w64-mingw32 set "C_INCLUDE_PATH=%MINGW_HOME%\include;%MINGW_HOME%\%SS%\include" set "CPLUS_INCLUDE_PATH=%C_INCLUDE_PATH%;%MINGW_HOME%\%SS%\include;%MINGW_HOME%\%SS%\include\c++;%MINGW_HOME%\%SS%\include\c++\%SS%;%MINGW_HOME%\%SS%\include\c++\backward" set LLVM_HOME=D:\CodeBlocks20161122\LLVM set "PATH=%LLVM_HOME%\bin;%PATH%" 执行之后，就可以既用g++编译，又用clang++编译了。 D:\>g++ --version

我觉得已经接近真相了，问题出在3.8以上版本的llvm的官方编译目标是 i686-pc-windows-msvc, D:\>clang++ --version clang version 4.0.0 (trunk) Target: i686-pc-windows-msvc Thread model: posix InstalledDir: D:\LLVM\bin D:\>cd \llvm391 D:\LLVM391>bin\clang++ --version clang version 3.9.1 (branches/release_39) Target: i686-pc-windows-msvc Thread model: posix InstalledDir: D:\LLVM391\bin D:\LLVM391>cd \LLVM381 D:\LLVM381>bin\clang++ --version clang version 3.8.1 (branches/release_38) Target: i686-pc-windows-msvc Thread model: posix InstalledDir: D:\LLVM381\bin D:\LLVM381>cd \llvm371 D:\LLVM371>bin\clang++ --version clang version 3.7.1 (tags/RELEASE_371/final) Target: i686-pc-windows-gnu Thread model: posix ---- set MINGW_HOME=D:\win32sj\mingw32 set MINGW_VERSION=6.3.0 set "PATH=%MINGW_HOME%\bin;%PATH%" set SS=i686-w64-mingw32 set "C_INCLUDE_PATH=%MINGW_HOME%\include;%MINGW_HOME%\%SS%\include" set "CPLUS_INCLUDE_PATH=%C_INCLUDE_PATH%;%MINGW_HOME%\%SS%\include;%MINGW_HOME%\%SS%\include\c++;%MINGW_HOME%\%SS%\include\c++\%SS%;%MINGW_HOME%\%SS%\include\c++\backward" set GCC_INCPATH=%MINGW_HOME%\lib\gcc\%SS%\%MINGW_VERSION%\include set "CPLUS_INCLUDE_PATH=%CPLUS_INCLUDE_PATH%;%GCC_INCPATH%;%GCC_INCPATH%\c++;%GCC_INCPATH%\c++\%SS%;%GCC_INCPATH%\c++\backward" set LLVM_HOME=D:\LLVM371 set "PATH=%LLVM_HOME%\bin;%PATH%" D:\>g++ --version g++ (i686-win32-sjlj-rev1, Built by MinGW-W64 project) 6.3.0 Copyright (C) 2016 Free Software Foundation, Inc.
