[cfe-users] Getting LLVM 6.0.0 lld-link to work with Code::Blocks

[Madison Link via cfe-users]

I'm trying to get LLVM/CLang 6.0.0-win64.exe to work on Code::Blocks 
17.2
The project I'm workign with is called Spectrum_Tester, and is a basic 
Windows project with a WinMain (and no wxWidgets).

I've got clang/clang++ compiling into .obj files, but lld-link.exe spits 
out a bunch of errors as follows:

Clang Compiler--Win)---------------

Process terminated with status 1 (0 minute(s), 0 second(s))
50 error(s), 1 warning(s) (0 minute(s), 0 second(s))

How do I resolve these?  I've tried using /SUBSYSTEM:Windows (with and 
without the /ENTRY:), but still get the error on _WinMainCRTStartup.
The others look like I might need to explicitely link to additional 
libs, but I'm listing every .lib that I used under GCC.

Thanks for any help
