papszWarpOptions = CSLSetNameValue(papszWarpOptions, "INIT_DEST", "nan" );
than I get zeros again in place of the nodata.
Works for me. You'll have to use your debugger I'm afraid
For the rec, VS2010 and a quite recent trunk version.
papszWarpOptions = CSLSetNameValue(papszWarpOptions, "INIT_DEST", "NO_DATA"
); ...
psWO->padfSrcNoDataReal = (double *)
CPLMalloc(psWO->nBandCount*sizeof(double)); psWO->padfSrcNoDataImag =
(double *) CPLMalloc(psWO->nBandCount*sizeof(double)); for (i = 0; i<
nBands; i++) {
psWO->padfSrcNoDataReal[i] = 500.;
psWO->padfSrcNoDataImag[i] = 0.0;
GDALSetRasterNoDataValue( GDALGetRasterBand(hDstDS, i+1),
pdfDstNodata[0]); }
Hum, do you realize that you set padfSrcNoDataReal ? INIT_DEST=NO_DATA will
fetch from padfDstNoDataReal as stated in the above doc...
Ghrrrrrrrrrr, blind copy-paste is-what-it-was
THANKS
psWO->padfDstNoDataReal[i] = mxGetNaN(); // ( mxGetNaN() --> a
Matlab API function)
Works fine now.

Read the error message again ;-) "does not support direct output file
creation"--> netCDF driver indeed only supports CreateCopy(), not Create()
(--> random access) which is required by gdalwarp.
The drivers that are supported as output driver for gdalwarp will have a '+'
in the output of gdalinfo --formats. Look at the difference betwenn GeoTIFF
and netCDF:
GTiff (rw+v): GeoTIFF
netCDF (rw): Network Common Data Format
