Re: [Qgis-user] ECW Licence
Hi In my mind (from the discussions we have had on this list) the issue is still not resolved. I think there is nothing to stop someone creating an unofficial / independent gdal + ecw installer if they are not so scrupulous / concerned about the licensing and make it so it overwrites the gdal in the official qgis installer. Maybe even this is considered bad Im not sure, but at the very least QGIS project wont be involved in any wrongdoing if the legality is questionable. But I think until its 100% confirmed that ECW license is compatibe with QGIS GDAL we should err on the side of caution when it comes to shipping ecw out of the box with QGIS.

It doesn't seems very simple… The ability of QGis (windows binaries) to read ECW is also a fundamental point for us if we want to adopt QGIS. Several opensource project (gvSIG, Mapserver, FWTools, …) based of course upon GDAL raster access, are already able to read ECW, but not QGIS.

Commercial license: Once off fee license with no royalties for commercial applications needing unlimited compression for ECW and JPEG 2000. Unless you need to support compression of images larger than 500MB in commercial applications, one of the two free licenses should address your needs. Release Date: Wednesday, September 06, 2006 ** Does it means we can expect a windows compiled distribution of QGIS that will read ECW ? Or is there still a problem ? Many Thanks !

Re: [Qgis-user] ECW Licence
Hi! I encountered the same question while building a Livecd with QGIS and others software. The matter is that you can't pre-build gdal with ecw enabled inside..or at least is what I heard around. I asked also for official answer from Earth Resource Mapping but got no answer.

I don't see any problem except that GDAL with built in GPL part cannot be distributed as MIT licensed library. It is possible to relicense MIT SW to GPL but it is not vice versa. IMO everything is OK if we add a note somewhere that a part of GDAL binary build is GPL and it restricts the use of GDAL to GPL. In any case we cannot violate ECW's GPL because everything we distribute is GPL or MIT, we dont use any piece code which is not GPL compatible.
