You have som other MPI include file hanging around that is getting intercepted before the MPI Uni one. Barry On Nov 22, 2011, at 12:00 PM, Mark F. Adams wrote:

Something is strange.

I'll suggeset

rm -rf externalpackages arch-macosx-gnu-seq

and then doing a fresh build.

And then verifying the build with 'make test'

If 'make test' works - and the application build is not working- I'd like to see the complete compile log thats producing this error.

wrt libmpiuni.a - all the relavent stuff is added to libpetsc.a and a separate libmpiuni.a is not created.

I'm trying to build a non MPI code and get this error:

Undefined symbols: "_ompi_mpi_comm_self", referenced from: _ompi_mpi_comm_self$non_lazy_ptr in libamrelliptic2d.Darwin.g++-4.gfortran.DEBUG.OPT.PETSC.a(PetscLinearSolver.o) (maybe you meant: _ompi_mpi_comm_self$non_lazy_ptr)

In the past I have linked libmpiuni.a but that did not seem to get created. Did libmpiuni.a go away or did my make fail ...
