Hello Jan, thanks for the pointer. I am setting
"-DMPI_{C,CXX,Fortran_{LIBRARIES,INCLUDE_PATH}" and I don't get MPI
warnings anymore, but instead I see a bulk of warnings right before
"make install" like this:
WARNING: target "demo_waveguide" requests linking to directory
"/home/juanlu/miniconda/envs/_build/lib". Targets may link only to
libraries. CMake is dropping the item.
The path that appears is the one I used for
-DMPI_{C,CXX,Fortran}_LIBRARIES. Is there any other way?

DOLFIN build system is not convinced MPI is available, so that
MPI_COMM_FOO are redefined by ifdefs in dolfin/common/MPI.h which
conflicts with MPI_COMMs from mpi.h. Check the CMake warnings about
missing MPI components and try helping to CMake by setting some
variables (see <build_dir>/CMakeCache.txt and
cmake/modules/FindMPI.cmake to figure out how could you help to CMake).

Hello all,
I'm trying to rebuild DOLFIN 1.6.0 using my conda recipes, and all of
a sudden I am getting a lot of MPI warnings and a final error at 96 %:

I attached the complete compilation log at[1]. When googling this
error I stumbled upon a fenics-support thread recommending to update
petsc[2], but I get the same errors with the latest version. The
errors are gone if I compile without PETSc support.
Any hint on what am I doing wrong?
Best,
Juan Luis Cano
