Visual Studio C++ and OpenMPI in windows: missing files.h

Question

I've just correctly installed Visual Studio Express C++ and OpenMPI. I've added the path to PATH variable:

C:\Program Files\OpenMPI_v1.5.5-win32\bin;
C:\Program Files\Microsoft Visual Studio 10.0\VC\bin;
C:\Program Files\Microsoft Visual Studio 10.0\Common7\IDE;
C:\Program Files\Microsoft Visual Studio 10.0\VC\include

and I've written a simple program in MPI on visual c++ express. The problem is that when I try to compile from prompt dos

mpicxx -o mpi mpi01.cpp

it tells me that there are a lot of missing files.h (no such file od directory) which are all inside C:\Program Files\Microsoft Visual Studio 10.0\VC\include But, as I've just said, I've included this in PATH. Why does it miss them all?

Answer 1

Your "prompt dos" should be the one you get when you launch the Visual Studio "Developper Command prompt". Shortcut located in your Start Menu -> Programs -> Microsoft Visual Studio -> Visual Studio Tools
