[gdal-dev] Why not netCDF output?

[Joaquim Luis]

Hi

While running this command

gdalwarp -s_srs +proj=latlong -t_srs "+proj=ortho +lon_0=-42 +lat_0=40 
+ellps=WGS84" -of netCDF lixo.grd proj.grd

I get

Output driver `netCDF' not recognised or does not support direct output 
file creation.  The following format drivers are configured
(a format list where netCDF is not listed)

but if I ask gdalwarp the list of formats, netCDF is listed there as 
(rw). Furthermore

gdalwarp --format netCDF
Format Details:
   Short Name: netCDF
   Long Name: Network Common Data Format
   Extension: nc
   Help Topic: frmt_netcdf.html
   Supports: CreateCopy() - Create dataset by copying another.
