Tru,
Thanks for the info. Best I can tell by looking at the various makefiles, and where I've changed them, the linking is looking at the 64-bit libs. I'm no programmer by any means, but I've built a few things in years past. Anyhow, one package, ncar graphics still gives the same messages about the incompatible libs, even with it pointing to the 64-bit lib directory. In building the mm5 products, the actual mm5 exe will build without hitch using the portland group compiler, but when using ifort of the intel 9.0 compiler, it too fails with the lib errors. I'm just not educated enough to know why there is an incompatibility. I'll ask around on some of the other discussion boards directly related to ncarg and mm5 and see what I can dig up there.
