You can download the current distribution- with many of the year 100 of the 20th century features from our ftp site: host: ftp.unidata.ucar.edu login: gbuddy passwd: XXXXXX once you are connected, cd to the nawips-5.4 directory and download the gempak54upc_pl15.tar.gz Since this is the complete distribution, you should place it in a clean directory and not in your current $NAWIPS directory- otherwise building will be a problem. The easiest way to build the new distribution is to mv your current distribution to a backup directory name, then create a new directory and unpack the tarfile contents there. For example, if you currently have $NAWIPS defined as /home/nawips, then mv /home/nawips /home/nawips.bak mkdir /home/nawips cd /home/nawips <ftp the distribution> gunzip -c gempak54upc_pl15.tar.gz | tar xvf - Once you have unpacked the distribution, edit the Gemenviron file and define the NAWIPS location to your installation directory (you can refer to your old Gemenviron file for data directory locations etc, but probably should just use it as a guide with the new distribution in case your old version Gemenviron is missing some of the things that the current distribution defines). You need to define NAWIPS in Gemenviron to build. After you have the distribution built, you can worry about defining the other datafile locations. After editing Gemenviron, "source Gemenviron" in your csh to define your directory locataions. Verify that $NAWIPS is correctly set with: echo $NAWIPS The build Gempak with: cd $NAWIPS make all when that completes, install the executables and clean the build tree with make install make clean Our current OS that we test our software for SGI is IRIX 6.5.6. After building and installing, you should setup the Gemenviron data locations for GEMDATA, HDS, SAT, and TEXT_DATA. If you are running Gempak decoders from your LDM, make sure the new decoder binaries from $GEMEXE are being used, and the $GEMTBL station and packing tables are being used. If you moved your old distribution out of the way and installed the new distribution in the same location as the old, then you won't have to change much. Your users should already be sourcing the Gemenviron file from that location. The last step will be to edit the $GARPHOME/config/Garp_defaults file if you use garp to define the model_keys and proj and garea names associated with how you store model data in your $HDS directory. The keys are unique identifiers that match the file names in the HDS directory. These are also used to define subdirectories under $GARPHOME/fdf/scalar and vector so that you have appropriate model fields for each different model. Steve Chiswell
