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 http://www.unidata.ucar.edu/software/mcidas/current/users_guide/workstation.html Michael James Unidata User Support > I'm having trouble with multiple > GEMPAK scripts running me out of shared memory ( a project we are > supporting is asking for gifs of 80 NIDS products in real-time every 5 > minutes and I'm having problems keeping up.)
