Trilinos' no-MPI ("SERIAL") build fails with the following build error:
/scratch/trilinos/workspace/trilinos-folder/Trilinos_generic_nightly@2/SERIAL_Release_gcc_4.9.3__DEV/Trilinos/packages/piro/test/MockModelEval_A_Tpetra.hpp:86:32: error: ‘MPI_Comm’ does not name a type
MockModelEval_A_Tpetra(const MPI_Comm appComm);It's not legal to use MPI_* types if MPI is not enabled.
Possible Solution
- Protect use of
MPI_*types with the appropriate macro, or - use a wrapper like
Teuchos::Comm.
