[cfe-users] CMake fails to build Clang for Visual C++ / Windows 7 - 32-bit

[Mailing List Email]

Clang can't parse VC11 headers, so you are much better off compiling it
with mingw (using VC11 to compile clang and using stdlibc++ headers
afterwards is a PITA).
Grab a mingw build from here:
http://sourceforge.net/projects/mingw-w64/files/Toolchains%20targetting%20Win32/Personal%20Builds/rubenvb/(tested
with gcc-4-6-dw2).
Then configure cmake with cmake -G "MinGW Makefiles"
-DCMAKE_BUILD_TYPE=Release <path_to_llvm>.
Then use mingw32-make to compile and off you go.
Clang works fine with stdlibc++ with gcc up to 4.8, but will only link with
with 4.6.3 according to my own experience.
