Hi,
It seems Microsoft C++ compiler could recognize what the code wants to
do, while Intel C++ compiler couldn't. I know a solution for this kind
of problem, but it involves some code base changes, I need some time to
test it. At moment, if you want to use Intel C++ compiler, the dirty
solution is just changing "OMPI_DECLSPEC" in ompi/mpi/cxx/functions.h to
"__declspec(dllexport)". Or you could switch to use Microsoft compiler
only for this libmpi_cxx project.
Thanks,
Shiqing

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
