Hello Sourish, You are correct that the netcdf fortran and C interfaces have been separated out; however, the former still has a dependency upon the latter. The C library (libnetcdf) is the `core` library, and the various interfaces (Fortran, C++, Python, etc) require the core C library. Installing the C library should resolve the issue for you! I hope this helps, please let me know if there are still issues! Have a great day, -Ward > Hello, > > I'm trying to build a fortran application using the netcdf fortran > library 4.4.2, but I am running up against several errors.
