Hi all,

In NAWIPS 7.5.1, NCEP added support to display netCDF 4 GOES-16/17
satellite imagery, and so the library will be compiled with netcdf4 enabled
from that release forward.  In August I began to merge the NCEP 7.5.1
changes into Unidata GEMPAK, and removed the "âdisable-netcdf4" flag from
the extlibs build, but have held back on releasing the 7.5.1 due to some
compilation issues with the new im_rcdf4 and gossae4 subroutines (which is
why Unidata GEMPAK is at release 7.4.5 right now).

The RPMs and Debian binaries are containerized builds where on each OS
GEMPAK is built from source, so I know for certain that the CentOS builds
are complete *in those container environments* and within the installed
RPMs. However, it appears that the Debian build is broken because of this,
as mentioned here, and needs some attention from me to account for hdf5 and
netcdf4.
