我试图在win10x64上为mingw_32生成llvm makefile，但是捕获了一些错误。

日志说我在tools / llvm-ar / CMakeLists.txt中调用的问题
add_llvm_tool_symlink(llvm-ranlib llvm-ar)
add_llvm_tool_symlink(llvm-lib llvm-ar)
add_llvm_tool_symlink(llvm-dlltool llvm-ar)
以及在tools / llvm-objcopy / CMakeLists.txt
中add_llvm_tool_symlink(llvm-strip llvm-objcopy)
和在tools / llvm-readobj / CMakeLists.txt
中add_llvm_tool_symlink(llvm-readelf llvm-readobj)
所有这些都指向cmake / modules / AddLLVM.cmake
string(SUBSTRING "${ARG_OUTPUT_DIR}" ${type_start} -1 path_suffix)
string(REPLACE "/${first_type}/" "/${CMAKE_CFG_INTDIR}/"
所以问题是如何解决此问题并生成makefile？谢谢
答案 0 :(得分：0)
生成器“ MinGW Makefiles”不是多配置生成器。因此，应不为其设置变量CMAKE_CONFIGURATION_TYPES。
通过在命令行中设置变量，您会混淆项目的CMakeLists.txt来假设您的生成器是多配置的，从而导致奇怪的错误。
