Could that generate any problems? I think you would get a different error in that case, plus I believe that "make install" takes the trouble to correct set file permissions... Try this: go to the nf_test directory of your netCDF install, and do a "make clean check" This will rebuild and retest the fortran 90 API, and show us how it is done. Look for the output related to tst_f90.f90. Thanks, Ed Ticket Details =================== Ticket ID: SWV-560841 Department: Support netCDF Priority: Normal Status: Open
