The latest released version of the netCDF C library is 18.104.22.168, but we think we're close to a release of version 4.3.0, with the netCDF header fix for files written from pnetcdf and other bug fixes. (Note that netCDF can read such files OK, the bug was the case of writing a netCDF file from pnetcdf, then trying to modify the metadata in the file header with netCDF.) The latest release candidate for netCDF-C is 4.3.0-rc3. If we don't encounter any unanticipated problems with 4.3.0-rc3, we plan to make a 4.3.0 release out of it, possibly by the end of next week. The 4.4-beta release you noticed is only for netCDF Fortran, which is a separate layer over the C library that is now in a separate software distribution. The latest official release of netCDF Fortran is version 4.2, which can be built and installed only after the netCDF C library on which it depends is installed. If you build the netCDF Fortran 4.2 release (or "4.4-beta1" release) after installing the netCDF C library 4.3.0, it will have the pnetcdf fix, because that's in the C layer. The "4.4-beta" name was somewhat of a misnomer indicating experimental support for Fortran 2003 C interoperability features. We plan to instead release a netCDF Fortran 4.3 version that will incorporate updated versions of the Fortran 2003 features curently in 4.4-beta1 as well as support for the current version 4.2 mechanisms for calling C functions from Fortran. The contributor of the Fortran-2003 features, Richard Weed, is currently working on those updates. The netCDF Fortran 4.3 release may be several months away, so it's good that the 4.2 and 4.4-beta releases will work OK with the upcoming 4.3.0 netCDF C release. One of our reasons for separating the C and Fortran libraries was to permit them to evolve independently, which means the version numbers don't have to match ... --Russ Russ Rew UCAR Unidata Program address@hidden http://www.unidata.ucar.edu Ticket Details =================== Ticket ID: GCG-755149 Department: Support netCDF Priority: Normal Status: Closed
