ECW works on one machine, not on other

[Jacob Delfos]

Hi List,

I'm moving a mapserver site from one machine to another, and even though I'm using the same mapserver and gdal files, and a similar setup, I get fatal crashes as soon as there is an ECW in the view. Without ECW it's fine. This occurs in php_mapscript, but also in shp2img. It happens in version 4.4.2 and 4.6.1 (from mapserver homepage), which seem to use the same GDAL. I don't have multiple conflicting versions of DLL's in my system path.

The pc on which it all works fine is Windows XP SP2. The ones on which it crashes are Windows XP SP1 and Windows 2000 SP4. There must be dependencies for ECW support which differ between different OS. What could those be? I have tried copying msvcrt.dll and gdi.dll, but to no avail. Strangely enough, when viewed with explorer, the map image (with ECW) does show up after the PHP fatal crash.

The dependency walker doesn't report errors. Could this have to do with the other ECW issues mentioned on the GDAL list?

Regards,

Jacob
