[LLVMdev] VS2005 compatibility

[Don Williamson]

OK, it's not that bad - it's even better than before :)

The main issue is RWMutex.inc and the use of PSRWLOCK. This requires _WIN32_WINNT to be >= 0x0600, which is not true for VS2005 SP1.

Rather than #define _WIN32_WINNT 0x0600 (the file notes that this should build on all Win32 variants), extending the copy/paste of winbase.h to this works fine:

#if defined(__MINGW32__) || _WIN32_WINNT < 0x0600

I'm still getting random crashes running llvm-tblgen.exe which I think is a known issue (I only need clang libs to build successfully so this isn't fatal for me).

Cheers,
- Don

Subject: [LLVMdev] VS2005 compatibility

Hi,

what are the goals of VS2005 support for building LLVM? I'm syncing to the v3 branch and while the branch compiles perfectly with VS2008, there are a significant amount of compile errors and warnings with VS2005 SP1 (8.0.50727.867 with KB926601 SP1, to be precise). I also have the latest WSDK installed.

A few months back there were only a few minor issues that I managed to clear up. I'm going to try and fix up my local copy but is it worth my time - should I just move to VS2008 and accept that VS2005 support is being slowly deprecated?

Thanks,
- Don
