MPICH2 and .NET issues

["T. Farago" <farago1@…>]

My project is built with the "multi-threaded DLL" runtime library
using MSVC 2008.

For MPI I include <mpi.h> and its two library files cxx.lib and
mpi.lib. Simply compiling and linking the project results in the
following error(s):

Linking...
LIBCMT.lib(hooks.obj) : error LNK2005: "void __cdecl terminate(void)"
(?terminate@@YAXXZ) already defined in MSVCRT.lib(MSVCR90.dll)

So I ignore "libcmt.lib" and get the following warning(s):

'ADIOI_FileD'; image may not run
cxx.lib(initcxx1.obj) : warning LNK4099: PDB 'vc80.pdb' was not found
with 'C:\MPICH2\lib\cxx.lib' or at 'i:\trunk\bin\Release\vc80.pdb';
linking object as if no debug info

The program crashes at startup during initialisation saying something
about "unhandled exception of type System.TypeInitializationException
in Unknown Module"

How can this be solved?
Best regards,

 Hi,
  Can you try compiling your code with the multithreaded static runtime
lib (/MT)? Also if you don't need the C++ MPI interfaces you can remove
cxx.lib from the list of dependencies.

Regards,
Jayesh

Hi,
 Can you send us a sample code that does not work for you ?

Hi,
 I wanted to have a sample code that you could not compile with "static
multithreaded runtime lib (/MT)" .

Hi Jayesh,

See my previous mail. But I've attached the source code. Use visual studio
and compile with /clr (.NET runtime) and /MD (dynamic runtime libraries).

Best regards, Tamas

Hi,

As I said before: "Unfortunately .NET (/clr) and multithreaded static lib
(/MT) are incompatible, you cannot even compile the project."

Visual Studio says: "Command line error D8016: '/MT' and '/clr' command-line
options are incompatible". So the only way to compile a .NET project is to
use the _dynamic_ runtime libraries. MPI works just fine with the static
runtime libraries, but my issues were with MPI in combination with .NET.

Best regards, Tamas

Hi,

Sorry for the delayed response. Since MPICH2 is compiled with VS static runtime lib you will have conflicts when compiling your .NET code. I would suggest you taking a look at MPI.NET by Indiana university folks (http://www.osl.iu.edu/research/mpi.net/). You will need MSMPI (Microsoft's MPI) to compile your code though (We haven't tested whether the lib works with MPICH2). Hope it helps.
