Hi list,
I would like to get some information about how to support ECW as a 
GDAL's plugin.
Andrea Aime, back from the FOSS4G, have proposed to improve the support 
to ECW format offered by our ImageIO-Ext project,

by leveraging on GDAL plugin mechanism.
Which steps are involved to support ECW Driver as a plugin? (on both 
Windows/Linux).

Should I also tweak the java bindings generation step to handle this?

Any information/suggestion/link would be greatly appreciated. (I have 
already taken a look at ticket 2385)


Daniele,

In addition to the notes already provided by someone else,
you might also want to review (and possibly improve) the wiki
topic:

  http://trac.osgeo.org/gdal/wiki/ECW

I would note that no change is required for the java binding
generation when adding new formats or plugins.

Best regards,

I have vague memories of a flag in the makefile that allowed
the ecw support to be built separately. The drill was something like
1) build gdal without ecw support (so that it's not statically linked)
2) go into the ecw format directory and build there independently,
   after tweaking the makefile or somethign like that
3) place the resulting library in a special directory

Cheers
Andrea
