I think you can fix the problem with

In my configuration I use both gcc and gfortran from HPC, and the
configuration goes fine. I do get errors on linking stratimikos, but
at least at this stage, it works.

And Trilinos 9.0.3 works fine with my setting. I had problems in the
past like the one you describe, but it was always because of mixing
different gcc, g++ and gfortran versions.

with the link below,


and specifying the compilers in cmake as /usr/local/bin/g*, I have no
issues like the one you describe here.
