Compilation error

I have upgraded my Mac to Mojave, which forced me to wipe the hard disc. Thus I am recompiling MPAS again from scratch.
I compiled with --disable netcdf4 and followed the ppt from the summer Boulder course.

I have a compile error (for init_atmosphere and atmosphere). It looks like I am missing a library, or a path incorrectly set.
Could anyone point me in the right direction. Details of the error are below.

Thanks

Alan...

Older versions of NETCDF contain interfaces for Fortran and C. Newer versions contain
only the C interface. I suspect you are using one of these. You need NETCDFF which is
the Fortran version. You will still need the standard version. The Fortran version will make
C calls.

Kevin,
Thanks. I thought I was using an older netcdf. I will check again. Do you have any suggestion for which versions are recommended?
Thanks
Alan

Alan...

I use NETCDF 3.6.2 on BRIDGES/PSC with no problems.

For what it's worth, I've been using the following library versions with generally good results:

• zlib 1.2.11
• HDF5 1.8.20
• parallel-netCDF 1.9.0
• netCDF C 4.6.1
• netCDF Fortran 4.4.4
• PIO2 master

Attached is a script that I follow (with some variation depending on compiler) to build these libraries assuming a working MPI installation.
With the current (v6.x) MPAS build system it will also be necessary to set the environment variables MPAS_EXTERNAL_LIBS and MPAS_EXTERNAL_INCLUDES as mentioned at the bottom of the script.

Hopefully this helps!

Thanks to all.
I will retry when I get back from London .. I need to restart from scratch (again)
Best wishes
Alan

Thanks for your comments
I think the script has worked now. Can't be sure, but the libraries seem to have compiled. I have put everything in the bin and lib.
I now get an error when I try to compile on the Mac. I used the old command

make gfortran CORE=init_atmosphere

I need to sort out my variables and paths, but a quick question .. (a) are there any other env variables other than

export PIO=$LIBBASE
########################################
# Other environment vars needed by MPAS
########################################
export MPAS_EXTERNAL_LIBS="-L${LIBBASE}/lib -lhdf5_hl -lhdf5 -ldl -lz"
export MPAS_EXTERNAL_INCLUDES="-I${LIBBASE}/include"

or (b)

any options needed to compile on MAC Mojave (i.e.where I can find info)

Thanks again
Alan

p.s. error is (which implies can't find pio)

`pio.mod` need you use `--enable-fortran` when you use `autoreconf` to build it. Or try using cmake.

Good luck.
