Hi Ben,
Sorry for response late.
The preprocessor problem is solved now, I don't know why Intel compiler
doesn't accept such kind of definitions. But if you use the latest
trunk, it should work.
I'm working on the import/export problem, and trying to fix it with a
better mechanism. I'll let you know when it's ready.
Thanks,
Shiqing

Shiqing,
I am having more import/export issues once I start using the openmpi
binaries that I built with the Microsoft compiler. I get unresolved
symbol errors for MPI::Comm::Comm and for MPI::Datatype::Free when I
link our own program. The C functions MPI_Comm_create and
MPI_Type_free are exported but the C++ equivalents apparently are not.
Our source code builds and runs without issues with the Linux version
of openmpi.
Do you have any suggestions?

Hi Ben,
I believe changing OMPI_DECLSPEC to __declspec(dllexport) inside
functions.h will allow the cxx module to build (and export the
function) but will break any client using (and thus trying to import)
it. OMPI_DECLSPEC should only be defined as __declspec(dllexport)
while compiling the cxx module (say when libmpi_cxx_EXPORTS is defined).
Yes, as long as there are more functions to export, they have to be
defined in that way. I don't see any option for Intel Compiler to
manage this automatically.
BTW, I also noticed that the Intel compiler has issues with the
preprocessor definitions for ompi_info "OMPI_CONFIGURE_DATE=\"03:18 PM
Wed 04/14/2010 \"" and
"OMPI_BUILD_DATE=\"03:18 PM Wed 04/14/2010 \"". The quotes around the
definitions throw it off completely. Is that something that CMake does
or do you instruct CMake to do this? Both the Intel and Microsoft
compiler work correctly without them.
In which project did you see those preprocessor definitions? Because
for me, I don't see them. Actually, they are not used as preprocessors
in the whole solution, but they are only some cached variables in
CMake. Could you please try to do a clean configuration with CMake,
and see if they still exists?
Thanks,
Shiqing
Thanks,
Ben
