Subject: [OMPI users] import/export issues on Windows

Hello,

 

When I use 1.4.2rc1 I am able build in Visual Studio 2005 (CMake 2.6.4
default settings VS2005 x64)but I get the following warning (among
others):

 

11>..\..\..\..\..\ompi\mpi\cxx\intercepts.cc(81) : warning C4273:
'MPI::InitializeIntercepts' : inconsistent dll linkage

11> E:\source\openmpi-1.4.1\ompi/mpi/cxx/functions.h(64) : see
previous definition of 'InitializeIntercepts'

 

When I convert the Visual Studio projects to use the Intel 10.1 compiler
(required for our production environment) this warning becomes an error:

 

11>E:\source\openmpi-1.4.2rc1\ompi\mpi\cxx\intercepts.cc(80): error: a
function declared "dllimport" may not be defined

11> MPI::InitializeIntercepts()

 

This issue seems related to
http://www.open-mpi.org/community/lists/users/2010/03/12392.php.

 

It appears to me that you are trying to use a single symbol to import
from the c module and export from cxx module at the same time.

 

Any help would be appreciated,

 

Ben
