[LLVMdev] Build Clang and LLVM on Win 8

[Kai Nacke]

Hi Giorgio,

here is another description how to compile LLVM on Windows:
http://wiki.dlang.org/Building_and_hacking_LDC_on_Windows_using_MSVC

Maybe this is helpful. I created this for Windows 7 but I also repeated 
it successfully on Windows 8.

Regards
Kai
