As I thought, this is getting quite complicated.

Ideally, I would like to distribute just plugins, but have seen way too many discussions on the list how to do it right and robust, so am considering just a whole build for simplicity.

Question is: do I need a commercial QT license. But I seem to get the answer: no, as long as I do not use it myself and only rely on PV whose source I reference.

Thanks,
Dominik

If Dominik is ditributing a standard version of paraview, and his plugins are only vtk/cxx/etc with no Qt custom panels, then it is safe to distribute freely and all is well. the distribution should refer to the source location of standard paraview, and the custom plugins can be closed source.

If there are custom panels using Qt code, then the Qt license becomes necessary if it is not GPL.

Better?

The terms of the Qt license allow, GPL compatible, or commerical. So if Dominik is making the source code available to his users, he can distribute freely as GPL, if the source is not available, then he requires a Qt License.

I no doubt have oversimplified it and await correction from others.

I am not an expert on this issue, but it seems like you'd have to buy
the commercial license to the qt gui libraries.
