Hi Michael, The netcdf-4.0-alpha17 version is alpha test code that is still under active development and porting, and the primary developer is on vacation for a couple of weeks. Sorry, but I'm afraid you will have to wait until he returns for an answer. If you want to keep helping debug the alpha release, you might get further by using the "--disable-extreme-numbers" option to configure, although I'm not sure this will get past the errors you are seeing. The latest supported release is netCDF-3.6.2. Thanks for your help in testing! --Russ Russ Rew UCAR Unidata Program address@hidden http://www.unidata.ucar.edu Ticket Details =================== Ticket ID: ZBH-836160 Department: Support netCDF Priority: High Status: Closed
