Tom: I finally got McIDAS to install on a different system, namely ATM12, an SGI Origin 200 (4 CPU) server which we use mostly for running big models. I hope the LDM and decoders can coexist with the modelers until we find a different platform. There was just one glitch in the make all process. A routine called servutil.c needed the addition of #include <arpa/inet.h> to compile sucessfully. I deduced this because the only other routine that had a reference to inet_ntoa (the cause of the compile error), namely m0addec.c had such a statement in a compiler directive control structure. Since the decision seemed to hinge on whether or not one was using gcc I just used the ELSE part above and the rest of the make went without a hitch and McIDAS passed all its tests. I now have the LDM running on ATM12 and am trying to get the McIDAS decoders configured to actually get some data. Hope your trip is-going/went well. Erick Lorenz, LAWR, UCDavis
