ECW works on one machine, not on other

[Olivier Gayte]

We had a similar problem yesterday, not with ECW but with OVF (handle by
gdal in both case).

We just replace the gdal12.dll file from the "good" machine to the "bad"
machine and now all work fine.

The 2 dll have the same version number and size but the date is different
and they come from a different distribution.

Regards

Olivier

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.

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.
