#69131: mpich-gcc12 @4.1.2_0+fortran: cmake no longer locates MPI_C and MPI_CXX
(but still finds MPI_Fortran OK)

 Reporter:  floquet-cxx  |      Owner:  (none)

 Priority:  Normal       |  Milestone:

-------------------------+--------------------
 The application I'm compiling/developing uses C++, C, F77 and MPI.  It has
 compiled and run fine for many years, though it's still in development.
 I was recently forced to "upgrade" from Ventura to Sonoma (14.2.1) and
 Xcode15 and now MPI_C and MPI_CXX can't be found by cmake (worked fine
 before the "upgrade").  Problem now happens on both ARM M2 macs I have.  I
 did  a clean reinstall if macports and all the ports I use.

 I'm not completely sure the issue is with mpich, but it doesn't occur with
 openmpi, so I am  assuming it's an mpich port issue as opposed to a cmake
 port issue.  Though I'm using gcc12, the same problem occurs with gcc13.

 Here are the commands I use to install gcc12 and mpich (on both Ventura
 and Sonoma)

 {{{

   sudo port -N install cmake
   sudo port -N install gcc12
   sudo port -N install mpich-gcc12
   sudo port select --set mpi mpich-gcc12-fortran

 }}}

 I require the MPI package with cmake for this application.  I believe this
 means that MPI_C, MPI_CXX and MPI_Fortran will be required as linkers -
 even though the top-level code is C++, some lower-level libraries in my
 application use C and F77.  So here are the errors I now get when cmake is
 run:

 Perhaps related: you can see that Apple's C and C++ compilers are
 selected, but GNU's Fortran compiler gets selected.  However, this
 combination has worked in  the past.

 I looks like the cmake MPI package resolver has a conflict with the
 version numbers of libmpicxx and libmpi although they are apparently
 consistent with libmpifort (all 4.0).

 Here is a listing of what is in /opt/local/lib/mpich-gcc12:

 {{{
