The MPAS 7.0 compilation fails during the pio check. I've edited the Makefile so the output is sent to standard output rather than /dev/null. Result is below along with additional info. Looks like a pathname problem related to a mystery MPAS include file (maybe?), but I've been unable to hunt it down. Thanks in advance for any help.

I'm on CentOS7 using gfortran 5.5.0_4 with mpich 3.3.1, NetCDF 4.6.3_1, PNetCDF 1.7.0_2, and pio 1.7.2.

-bash-4.2$ echo $CORE $NETCDF $PNETCDF $PIO

I've managed to pass the pio check by adding "use pnetcdf" to the pio code generation line:

@echo "program pio1; use pio; use pnetcdf; use pionfatt_mod; integer, parameter :: MPAS_IO_OFFSET_KIND = PIO_OFFSET; integer, parameter :: MPAS_INT_FILLVAL = NF_FILL_INT; end program" > pio1.f90

@echo "program pio2; use pio; use pnetcdf; integer, parameter :: MPAS_IO_OFFSET_KIND = PIO_OFFSET_KIND; integer, parameter :: MPAS_INT_FILLVAL = PIO_FILL_INT; end program" > pio2.f90

However, the compile for MPAS now fails in mpas_io.F, no doubt for the same reason. Does 'use pnetcdf' now need to be included in various source files and modules?

After a bit of testing, I think the issue is that your PIO library was not compiled with support for the parallel-netCDF library. The simplest workaround may be to install the PIO 1.7.2 library from source rather than using Homebrew. You can do this by downloading the PIO 1.7.2 source code from here: https://github.com/NCAR/ParallelIO/releases/tag/pio1_7_2 . After unpacking the PIO 1.7.2 tar file, you'll need to clone the genf90 repository in the top-level directory with:
Code: 
git clone https://github.com/PARALLELIO/genf90.git bin
Then, after setting the FC, CC, NETCDF_PATH, and PNETCDF_PATH environment variables, you can run
Code: 
./configure --prefix=/where/to/install/pio
make
make install
from the pio/ subdirectory. Setting the PIO environment variable to the installation prefix specified in the configure command should be all that's needed before building MPAS.
 
Thanks. I think I've come to the same conclusion. I'm now downloading the latest PIO (v 2.x) as well as the latest pnetcdf. Then I'll have the most current everything, and I will try a clean install. I appreciate the compile tips. I'll keep hacking away and see if I can get some incarnation of some version to work.
 
The "iolib_installation.sh" script at http://www2.mmm.ucar.edu/people/duda/files/mpas/sources/ may be helpful in installing the software stack needed by MPAS.
