gnudatalanguage @0.9.6 build error

[majoc-at-astro (majoc-at-astro)]

Port hdf5 @1.10.0_1+cxx+fortran+gcc5+hl+openmpi present and active, but build fails with:

/opt/local/include/H5public.h:61:13: fatal error: 'mpi.h' file not found

Please see enclosed build log for 10.11 (10.10 has an exactly similar build error).

This appears to be a different problem from Trac #51865, for which thanks. I've seen failures of the above form with other ports in our build set, for which the usual fix is to add +openmpi, or in one instance +openmp; but attempting to install gnudatalanguage with +openmp yields conflicts between other packages and gcc44.

Thanks in advance. Do please let me know if you require more information. Apologies for terseness and typos: shredded-fingers error.

openmpi is disabled because it is not supported. I tried but I still have build errors. You should be able to install gdl without MPI or with MPICH.

Replying to takeshi@…:

openmpi is disabled because it is not supported. I tried but I still have build errors. You should be able to install gdl without MPI or with MPICH.

I tried and failed with MPICH: there's some incompatibility with our OpenMPI-oriented build set which I frankly didn't understand. We found a workaround which keeps faith with the remainder of our setup:

port select --set mpi openmpi-gcc5-fortran

.... (immediately after port install openmpi-gcc5 +fortran in the build sequence) causes the correct mpi.h to be found by the GDL build, which then succeeds.

Hope this helps. Apologies for not replying earlier.

Your workaround probably does not enable the compiliation of gdl-0.9.6/src/mpi.cpp although it resolve the the problem with mpi.h. Motivated by your feedback, I investigated the build process and source. MPI_C_COMPILER and MPI_CXX_COMPILER rather than MPI_COMPILER have to be set. With a little patch, I was able to compile gdl-0.9.6/src/mpi.cpp with OpenMPI. Done in r150944.
