[cfe-dev] Problems Building clang / llvm "examples" in Windows7 / VS2010,

Hi All,
I've been experimenting with a recent build of clang / llvm.
I downloaded a new trunk following the directions from:
http://clang.llvm.org/get_started.html
http://wiki.llvm.org/How_do_I_compile_on_Visual_C%2B%2B%3F
Below is my configuration:
Clang / LLVM Build: 111612
OS: Windows7 - 32bit
Dev. Environment: Visual Studio 2010
CMake Version: 2.8.0
I can build fine without errors if I use the default configuration from the
CMake GUI.
Nevertheless, I am getting a large number of warnings (173).
Additionally, when I use the CMake GUI, and when I check the flags for:
. Clang->Examples
. llvm->Examples
I'm getting LNK2019 error (Unresolved external symbol).
It's essentially not building:
. PrintFunctionNames.dll
. clang-interpreter.exe
Is it possible that my CMake configuration is not setup properly or perhaps
an environment variable is not setup properly?
I've spent a ton of time trying to track this down, but have had no luck so
far..
I've also read all the posts on problems with Visual Studio 2010 due to
Clangs lack of support for C++ 0x, but this doesn't look like the cause
here, but perhaps I'm wrong...
Any suggestions would be appreciated.
Thanks,
Yahya
Below is the Visual Studio 2010 output:
