[gdal-dev] gdaltransform results differs from qgis

[Antonio Parrotta]

I'm trying proj4 too, but after downloaded binary and

set PROJ_LIB=<nad_intallation_dir>
set set PATH=%PATH%;<bin_intallation_path>

>cs2cs -v  +proj=latlong +datum=WGS84 +to +init=epsg:3003
+towgs84=-104.1,-49.1,-9.9,0.971,-2.917,0.714,-11.68

I obtain :
Using to definition: init=epsg:3003
towgs84=-104.1,-49.1,-9.9,0.971,-2.917,0.714,-11.68
Rel. 4.4.6, 3 March 2003
<cs2cs>:
projection initialization failure
cause: no options found in 'init' file
program abnormally terminated

maybe I'm missing some file,  is it?

thanks
Antonio
