Yes, I don't understand why people keep saying they can't be redistributed. But look at that license more closely: - you can distribute the libs with a "desktop" application, not a "server" application or a "library". The way I understood this was that you generally couldn't distribute them with GDAL, but you might be able to argue that it is within the "spirit" of the license to distribute them with QGIS binary packages, because in that case you are providing gdal as part of QGIS, a "desktop" program, rather than as a library for a developer. (Maybe some people would even take the view that the GDAL utilities in a binary GDAL package are also "desktop" programs.) - Isn't there another clause stating that your program must display a particular statement about the user of their copyright software, and you need to make sure your users agree to a license (i.e. make them click through a license screen like in the installers for most Windows software, and if they don't agree with it then it won't be installed)? - And isn't there a clause stating that you must register the users (collect information about them)? This is the real hassle, and I think most of the other people bundling ecw support with free GIS packages are violating it. I was wanting to provide a package of one of the ECW example programs (for editing ECW headers), but I really don't have the energy to organise this nonsense. It might be easier to distribute with QGIS the old version that is used on Linux. Alister
