[gdal-dev] libecwj2 ?

[Oyvind Idland]

Thanks !

I did allmost exactly the same as you, but didn't include -DNO_COMPRESS.

It compiles fine now. However, seems like it can't load gdal_ECW_JP2ECW.dll
anymore.

I now compile GDAL as a static lib, with ECW as a plugin. Could this result
in GDAL not loading dynamic plugins ?
