Hi Mark, I see you have g95 as a Fortran compiler, but I don't think that comes with the MacOS X Developer tools, which come with a special version of gcc tailored for MacOS X. Did you get the latest g95 from fink? I think setting the environment variable export LIBS='-lSystemStubs' may be needed. Here is a note on how Tim Hume got netCDF to build correctly with g95 on MacOS X using the LIBS environment variable: http://www.unidata.ucar.edu/software/netcdf/docs/other-builds.html#osx-g95 --Russ Russ Rew UCAR Unidata Program address@hidden http://www.unidata.ucar.edu Ticket Details =================== Ticket ID: IPE-411197 Department: Support netCDF Priority: Normal Status: Closed
