Hi Jeff,
They are definitions for enabling dllexport/import declarations on Windows, and
they existed since the initial version for Cygwin. Normally these definitions
are hidden via mpicc command wrapper, but on Windows, when user tries to
compile a project in Visual Studio, they have to be added manually.
I think there might be some workaround to get rid of them. Need some time to
test.
Regards,
Shiqing

What are these defines? Shouldn't they be invisible when compiling MPI
applications?

Hi Greg,
Glad to hear that it works for you.
And yes, these definitions are necessary for compiling any MPI application on
Windows.

Definitions and set OMPI_IMPORTS OPAL_IMPORTS and ORTE_IMPORTS)
