Howdy! NetCDF is having a problem getting some answers related to fortran types. Note the following from your output: checking for Fortran "byte"... yes checking for Fortran "integer*2"... yes checking if Fortran "byte" is C "signed char"... yes checking if Fortran "byte" is C "short"... yes checking if Fortran "byte" is C "int"... yes checking if Fortran "byte" is C "long"... yes checking if Fortran "integer*2" is C "short"... yes checking if Fortran "integer*2" is C "int"... yes checking if Fortran "integer*2" is C "long"... yes checking if Fortran "integer" is C "int"... yes This is not right! These should not all be "yes." Can you send me your config.log? Ed Ticket Details =================== Ticket ID: SET-499655 Department: Support netCDF Priority: Normal Status: Open
