I have never successfully managed it for long. I don't know the answer to your specific question. Certainly, if I were to want to try such a thing again, I would do so with the latest and greatest netCDF code, which can be obtained here: ftp://www.unidata.ucar.edu/pub/netcdf/snapshot/netcdf-4-daily.tar.gz Although the build has become much more complex with the addition of opendap and netCDF-4/HDF5, these features can be turned off in the configure (--disable-netcdf-4 --disable-opendap) and that will hide most of the new stuff. But my first line of defense is the visual studio build for netCDF. If you want to do a visual studio build, use the solution file in the win32/NET directory of the distribution. If you do get this working, a patch would help other netCDF users... Thanks, Ed Ticket Details =================== Ticket ID: NDT-203834 Department: Support netCDF Priority: Normal Status: Closed
