I added Ubuntugis unstable repo and installed Qgis, libgdal-ecw-src, libecwj2-3.3 but still do not work.
When I attempt to open an ecw file with Qgis it crash and tells me that there are problems with this libraries:
I am using ubuntu 12.10 and when I do:
gdalinfo --formats|grep -i ecw
it seems to work.
ECW (rw): ERDAS Compressed Wavelets (SDK 3.x) JP2ECW (rw+v): ERDAS JPEG2000 (SDK 3.x)
What is the problem?
