Hi Greg,

The easiest solution I can offer is to use the _gf version of the program 
you're using, which will link the driver directory to the program and thus 
doesn't require both gplt and the device driver. For example, gdcntr_gf links 
the gif driver with gdcntr. You can build these programs by running the "make 
programs_gf" command in $NAWIPS.

As for the issue of shared memory, you may decide that you want to manually 
allocate more shared memory on your system, and there is a McIDAS man page 
which details this at
