A bit more detail. mpi4py's setup.py attempts to determine what compilers to use to compile and link MPI programs.
It looks like it failed to do so for you somehow:
copying src/mpi4py/include/mpi4py/mpi4py.i ->
build/lib.macosx-10.5-x86_64-3.6/mpi4py/include/mpi4py
copying src/mpi4py/include/mpi4py/mpi.pxi ->
build/lib.macosx-10.5-x86_64-3.6/mpi4py/include/mpi4py
running build_clib MPI configuration: [mpi] from 'mpi.cfg' checking for library 'lmpe' ...
If I run "pip install -vvv mpi4py" I see:
running build_clib MPI configuration: [mpi] from 'mpi.cfg' MPI C compiler: /usr/local/bin/mpicc MPI C++ compiler: /usr/local/bin/mpicxx MPI F compiler: /usr/local/bin/mpifort MPI F90 compiler: /usr/local/bin/mpif90 MPI F77 compiler: /usr/local/bin/mpif77 checking for library 'lmpe' ...
I notice that your environment sets "mpiexec" to something in $PETSC_DIR/$PETSC_ARCH/bin
But that directory is not in your PATH. Is that also where mpicc etc.. live?
You can say:
MPICC=...; MPICXX=...; pip install -vvv mpi4py to see if that works.
In theory you can say "firedrake-install --mpicc=/path/to/mpicc --mpicxx=... --mpif90=..." but I am not 100% confident that that sets things up correctly for the mpi4py installation (only the PETSc build).
Since (unfortunately) recovering from a part-failed install is a "remove and try again" process, to speed up pinning down the issue can we try:
$ python3 -m venv foo $ . foo/bin/activate $ pip install -vvv --no-binary mpi4py mpi4py
And see what happens?
The env variables worked. I like that trick for building just one section. Restarting the full build... Thanks, Matt
Cheers,
Lawrence
