Because I need to link to some libraries that have been compiled with gcc I need to compile my programs under gcc 2.8.1. I am currently able to compile the programs but when I try to run them I get an "Exec format error". Does anybody know what the proper compiler flags to gcc are for linking to the Sun MPI library and running in the multiprocessor environment ? Thanks in advance for any tips (I'll try to summarize responses), -- KY Karl Young UCSF,VA Medical Center MRS Unit (114M) 4150 Clement Street San Francisco, CA 94121 Email: kyoung@itsa.ucsf.edu Phone: (415) 750-2158 lab (415) 750-9463 home FAX: (415) 668-2864
