So mpicc builds it completely? The only thing I can think of is look
closely at both the compile and link command lines and see what's
different. It might be going sideways at the compile from something in
an include with a preprocessor def.

Hi Damien,
I've checked and double-checked, and I can't see anything not 32-bit.
In fact my VS2005 only knows about 32-bit.
I just tested copying the source code with appropriate include
directories to another directory and built the executable successfully
with mpicc. But I can't see that there is anything in the mpicc link
(with --showme:link) that is not in VS. The command line in VS has a
lot more stuff in it, to be sure.

Gib,
If you have OMPI_IMPORTS set that usually removes those symbol
errors. Are you absolutely sure you have everything set to 32-bit in
Visual Studio?

I am building the Sundials examples, with MS Visual Studio 2005
version 8 (i.e. 32-bit) on Windows 7 64-bit. The OpenMPI version is
OpenMPI_1.6.2-win32.
All the parallel examples fail with the same linker errors. I have
added the preprocessor definitions OMPI_IMPORTS, OPAL_IMPORTS and
ORTE_IMPORTS. The libraries that are being linked are: libmpi.lib,
libmpi_cxx.lib, libopen-pal.lib, libopen-rte.lib.
Here are the errors:

What am I missing?
