Which I/O API version? Which netCDF version?
See https://www.cmascenter.org/ioapi/documentation/all_versions/html/AVAIL.html#ncf4:
Evidently, starting with netCDF-Fortran 4.4.2, UCAR in their wisdom decided to silently eliminate the CALL NC*() Fortran interfaces in terms of which the I/O API was originally implemented. [If you can find any documentation indicating this intent on the web, I would enjoy seeing it; I can’t find it.]
I/O API Version 3.2 was tediously re-coded to replace all 943 of these calls by the newer IERR=NF_*() Fortran interfaces that are still supported. Prior editions of the I/O API will have link errors with netCDF-Fortran 4.4.2 or later, because routines such as NCCLOS() are no longer in that library.
…which is exactly what you’re seeing,
