Hi Dr. Duran, Here's some information from Intel on how they recommend building netCDF using their ifort compiler: http://www.intel.com/support/performancetools/sb/CS-027812.htm If that doesn't work, here is a recommendation from a user: http://www.unidata.ucar.edu/software/netcdf/docs/other-builds.html#ifort_mac_64 Finally, we've made some portability improvements in the latest netCDF beta release, so if neither of the above works for you, you could try building with ftp://ftp.unidata.ucar.edu/pub/netcdf/netcdf-beta.tar.gz I hope this helps ... --Russ Russ Rew UCAR Unidata Program address@hidden http://www.unidata.ucar.edu Ticket Details =================== Ticket ID: UUI-966940 Department: Support netCDF Priority: Normal Status: Closed
