Hi Benjamin,
To use *ECW* in *server*-based products requires additional licensing
permissions.
If you have the licence agreement, you can build GDAL with ECW, but you
also need to build QGIS Server with ECW support.

Hello,
I'm currently a student at the University of Lille, I recently gained
access to some mapfiles so I'm not accustomed to qgis yet. I would
like to use a map server to share these files inside of my local network.
I want my server to be as complete as possible so I did some research
and I found some libraries such as kea, Mr.Sid or ecw which can be
built with gdal in order to read different files' types.
I built gdal with kea and Mr.Sid which work on my server, however,
when I used ecw with the free version of SDK and I completed the
installation, I got a warning saying that ecw had been skipped in the
server and when I added an ecw file to a qgis project, my project
wasn't working anymore (request timed-out).
I made a mistake during the installation, ecw has a server supported
version while I used the free desktop version. Does the skipping issue
come from the difference between licenses?
Is it possible to build gdal with ecw and use it in qgis-server
legally for free?
If it's not possible and in the hypothesis that I managed to get a
license, will it be working properly once gdal is built with the
correct version of ecw?
Thanks a lot for your time
Benjamin Deregnaucourt
