The license analysis done by Debian is linked from this thread:
http://lists.alioth.debian.org/pipermail/pkg-grass-general/2005-August/001083.html
In that thread we discuss builing ecw support as a separate loadable
module to go in Debian contrib, although we haven't yet done so.
I think it is important to note that ER Mapper describes this license as
GPL-like, but it is not the GPL. Josh Triplet also says, "Furthermore,
it should be noted that while their license seems to grant permission to
build GPLed software based on their system, the GPL itself does *not*
grant that permission (since this license is non-free), so any such
GPLed software would need an exception clause to be distributable."
It is also possible that the license has changed since these
discussions. They may have removed the "don't use it with a server
system" requirement, I forget. The restriction on changing the ECW file
format is the main sticking point when it comes to Freeness, though.

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.

I have heard pepole at Debian has analyzed the licence, and they found
it almost compatible with free redistribution.
Canop somebody clarify this?
I think this is a good candidate for a FAQ

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.

[Qgis-user] ECW Licence
Hi,
I send an email in this list to know why qgis 0.8 can't read ecw file. Tim
Sutton reply me that he was "still unclear if the
licensing of ECW is compatible with GPL applications".
I just read the SDK pages about the librairy :
"You can **select one of the three simple** license agreements for use of this
library (full license agreement text is available here and in the SDK
itself).
Licensing:
* Free use license: A free license, providing unlimited
read/500MB-per-image compression for ECW and JPEG 2000 in any application
including commercial applications.
* GPL-style license: A free license, providing unlimited read/unlimited
compression for ECW and JPEG 2000 in any GPL style application.
* Commercial license: Once off fee license with no royalties for
commercial applications needing unlimited compression for ECW and JPEG
2000."
So it seems possible to use a GPL-like licence for the librairy. In the
licence.txt we can read :
"Use of the ECW JPEG 2000 SDK with Unlimited Decompressing and Unlimited
Compression for applications licensed under a GNU General Public style
license ("GPL") is governed by the "ECW JPEG 2000 SDK PUBLIC USE LICENSE
AGREEMENT"."
and :
"The intent of this license is to establish **freedom to share** and change
the software regulated by this license under the open source model and is
applicable to the use of the ECW JPEG 2000 SDK with Unlimited Decompressing
and Unlimited Compression for applications licensed under a GNU General
Public style license ("GPL") as set out below.
**This license applies to any use of the Software Product solely intended to
develop or be distributed with products that are licensed under a license
similar to a General Public License ("GPL") and at no charge to the public**.
This license covers modification and distribution of the Software, use of
third-party application programs based on the Software, and development of
free software that uses the Software."
I am not a guru about law and licence, but do you think this quote allow qgis
team to distribute qgis with ecw librairy ?
Sorry if I missed something !
Regards,
Y.
