build on windows #11

Closed looooo closed 5 years ago

What is missing to enable windows builds?

openmpi ? would it be possible to build without mpi?
openblas: https://anaconda.org/conda-forge/openblas/files

Trilinos is designed to be optionally built without MPI. In the context of an Anaconda package, we would probably want an independent package such as trilinos-serial.

@ocefpaf I have been wondering about a serial version of trilinos. Trilinos con be configured with MPI turned off. How would we do this? Could none be one of the mpi variants? Seems unlikely to work, even if none is a valid option. Would we need a completely different trilinos-serial package? How could we make it exclusive to the trilinos package? Thx

I don't know how to do that b/c I'm not a trilinos user, sorry.

It should be an option if that is not possible already. Pinging @minrk who may have already thought about this.

actually-none null seems to be scrubbed from the matrix by conda-build, so I've been using the string "nompi" e.g. in hdf5. If you want to have a 'default' install, then the gist is to have a track_features for trilinos_mpich or trilinos_nompi for only the non-preferred variants.
