Try it out, and let us know if something doesn't work. I wrote the original Driver code based on a personal GCC build (with default options) and the Arch MinGW-w64 cross toolchain. So your mileage may vary.<br>

To make clang++ work (easily) with the latest mingw-w64 builds by the Mingw-build project, I added more paths to the search for default include directories, and it works splendid. See the attached patch.<br>
In short, the issue is that clang is searching for versioned paths, but (at least for the package with gcc4.9.0) the C++ include paths aren't versioned. For example, right now, clang is searching for<br>
[...]/include/c++/4.8.0<br>
while really this folder is<br>
[...]/x86_64-w64-mingw32/<u></u>include/c++<br>
<br>
Are you happy to add the following paths to the default list?<br>
<sysroot>/x86_64-w64-mingw32/<u></u>include/c++/<br>
<sysroot>/x86_64-w64-mingw32/<u></u>include/c++/x86_64-w64-mingw32<br>
<sysroot>/x86_64-w64-mingw32/<u></u>include/c++/backward<br>
<sysroot>/i686-w64-mingw32/<u></u>include/c++/<br>
<sysroot>/i686-w64-mingw32/<u></u>include/c++/i686-w64-mingw32<br>
<sysroot>/i686-w64-mingw32/<u></u>include/c++/backward<br>
(the final 3 are a guess, judging from the symmetry in the pathnames that clang already searches for)<br>
This assumes gcc and clang are in <sysroot>/bin.<br>
I believe it will make life much easier for Windows developers who want to give clang a spin.<br>
<br>
If so, I will clean up the modifications and submit it for review.<br>
<br>
Thanks,<br>
Johan<br>
