Hi Gilbert, re: I upgrade to FC6 > Cool! I assume LDM works without a hitch. But... I've built LDM-6.4.6 on my machie, but havn't ingesting data yet. From what I see the FC6 environment is not much, if any, different than FC5, so I am not expecting any problems. But you never know... re: gfortran is NOT ready for primetime yet > Ouch. Do you know why? I think that work is needed in how it parces source code. > What is its progress? I am not exactly sure what you mean. A LOT of McIDAS works with no problems. A simple GRDLIST listing failed with a runtime error citing the line of a format statment in grdlist.pgm. Since there is nothing weird with the line in question, I am assuming that the problem lies in gfortran. > Will McIDAS still work fine using the f77 compilers? Yup, I did a yum installations of the gcc compatibility code (forget the exact yum command line at the moment), and it installed g77. I rebuilt McIDAS using gcc/g77 and everything so far is working without problem. > Are there bug reports for these? I don't know. Since I have been preparing for my McIDAS workshop (starts Monday morning), I have not had any time to find out if what I saw is a known deficiency.
