Ways to Get Support

NetCDF Mailing Lists

Mailing Lists NetCDF-related mailing lists of general interest for discussing installation issues and troubleshooting, as well as general software announcments and bug fixes, etc.

List Name List Description
netcdfgroup
@unidata.ucar.edu
High list traffic 		netcdfgroup is an unmoderated mailing list for announcements, discussions, bug reports, and questions about netCDF software. Typical postings include announcements of new versions, patches, and bug fixes; questions about representing specific data relationships using the netCDF model; general discussions about scientific data access, including the use of other interfaces; and discussion of issues and priorities affecting the further development of the netCDF interfaces and software. Questions and discussion about porting the software to new platforms should be in the netcdf-porting mailing list.

netcdf-porting
@unidata.ucar.edu
Low list traffic 		netcdf-porting is an unmoderated mailing list for questions and discussion of porting netCDF to new platforms. Although we try to support most platforms, it is not possible for Unidata to support all platforms. Currently supported netCDF platforms can be found on the daily testing web pages for netCDF-3 and netCDF-4. All other platforms are unsupported. Since netCDF has already been ported to many platforms, getting it to build and test on a new platform is usually not difficult. Bug reports (including build problems on currently supported platforms) should be sent to support-netcdf@unidata.ucar.edu. General purpose discussion of netCDF should take place in the netcdfgoup mailing list.
