Any version of the netCDF C library > version 4.1.3 is compatible with netcdf-fortran-4.2. The most recent version of the netCDF C library is netcdf-4.3.0, so that would currently have the most bug fixes for anything that works with netcdf-fortran-4.2. But I suspect the problem you are seeing is simpler than any recent bug fixed in the netCDF C library, so netcdf-4.2.0 is probably OK. If you have not built the netCDF Fortran as a shared library (for example by configuring with --disable-shared), then you need to link your Fortran programs using both the Fortran and C libraries, for example gfortran myprog.f90 -o myprog -I/usr/local/include -L/usr/local/lib -lnetcdff -lnetcdf and possibly other libraries as well. You can see what's needed by running the nf-config utility, which is installed when you build and install netcdf-fortran, like so nf-config --flibs You can even use this on your compile line, for example: gfortran myprog.f90 -o myprog `nf-config --fflags --flibs` If your system has the pkg-config program, you can use it instead, as follows: gfortran myprog.f90 -o myprog `pkg-config --cflags --libs netcdf-fortran` (For pkg-config, "cflags" means "compiler flags", so that's not a typo.) --Russ Russ Rew UCAR Unidata Program address@hidden http://www.unidata.ucar.edu Ticket Details =================== Ticket ID: ILQ-730613 Department: Support netCDF Priority: Normal Status: Closed
