but it won't work. (gdal not supported ecw in my grass 6.0 version)

What will the easiest way to do this?
Must I compile gdal with ecw support ot is there another way?

H:

yes.

I should mention that there is a possibility you can only get the ECW SDK
to work with gdal in MS Windows (??). In that case either a) try to run
GRASS with a ecw-enabled gdal in Windows, or b) use gdal_translate in
Windows to make a GeoTiff from the ECW data, and then transport the
GeoTiff back to Linux/Mac/whatever..

check for ECW support with "gdalinfo --formats"

It is possible to get the ECW SDK to work in linux as well. I use it for coding jp2 files all the time as jasper is a resource pig.

Regarding ECW and GDAL on windows, a thread on that recently occurred on the FWTools list: http://lists.maptools.org/pipermail/fwtools/2008-April/001213.html
