[Trilinos-Users] Pytrilinos Error

Ajay,

I would have to know more about your set up to understand why this might be happening.  As Bill said, there is no need to link in PyTrilinos for this example, so I wouldn't worry about taking it out.

Ajay,

You are running a pure C++, pure Epetra example, so you should not be linking to the pytrilinos library.  Jim, any idea why this might be happening?

As for not being able to import PyTrilinos in python, it is probably the same error you are seeing here: undefined references (although I would like to see the python exception that you get).  The errors you sent indicate that the python header or library is not found, so it would help if you would send the results of running cmake.
