Hi all,

I've already installed 1.7.2 (2010/04/23) GDAL release from OSGeo4W
and the ECW JPEG2000 SDK from ERDAS.

After that I copy the dll's of C:\OSGeo4W\bin\ directory
(lti_dsdk_cdll lti_dsdk_dll.dll) and the dll's contain in "C:\Program
Files (x86)\ERDAS\ERDAS ECW JPEG2000 Read SDK\bin\vc90\win32\"
 in the "C:\WINDOWS\SysWOW64\" directory

I would like to mosaic several ecw file with the "gdal_merge.py"
utilies but I have got these risults:

C:\OSGeo4W\apps\gdal-17\bin>python gdal_merge.py -init 255 -of ECW -co
LARGE_OK=YES -o E:\temp\test_mosaic\testMosaic.ecw --optfile
Format driver ECW not found, pick a supported driver.

am I forgot to do something or am I using the tool in a wrong way??

OS: windows XP professional 64 bit SP2

thanks in advance
