Stop Clang from including problem headers from visual studio 11

Kim · May 8, 2013, 9:19pm

Hi guys,

I'm having an issue with some headers from VS11 that clang is automatically including. This is a problem that I haven't been able to find info on but I'm happy to just use the VS 10 headers unless someone knows how to fix the problem with VS11. So my question: how do I stop the clang driver from automatically adding VS 11 to the isystem includes?

The only reference I found to my problem online was this:
http://lists.cs.uiuc.edu/pipermail/llvmbugs/2013-January/026857.html

Here's the errors that come up with VS 11

You most likely need to remove INCLUDE from your environment. The
clang driver forwards that var to the -cc1 command line, which I think
is what's happening here.

Joao_Matos · May 8, 2013, 9:57pm

We have been discussing that problem, see: http://lists.cs.uiuc.edu/pipermail/cfe-dev/2013-May/029398.html

Whoops, looks like even if you unset %INCLUDE% clang still falls back
to heuristics to find MSVC's headers.

Looking at the code in clang/lib/Driver/WindowsToolChain.cpp shows you
can pass -nostdinc to turn this all off.

I've set VCINSTALLDIR to point to my VC10 toolset in my shell's
environment, but it looks like overriding any of the VS*COMNTOOLS env
vars would work too.

E.g.

$ SET VCINSTALLDIR=C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\
$ clang++ ...

Like Reid, I started from here to find my way:
