Huh? I used Qucs many moons ago and it definitely was complete with GUI.

Unfortunately Qucs is unmaintained, probably doesn't compile anymore on newer distributions and its binaries were therefore removed from many repositories. Another problem: Qucs was released as GPL while QucsStudio, which uses its sources, has been kept closed by the authors; I smell a GPL violation here.

Unless they have been specifically granted a licence other than the GPL, which the original maintainer(s) would have the right to do (assuming other contributors, if any, agreed or signed over the relevant rights when contributing). Edit: in fact both qucs and qucstudio are listed as authored by Michael Margraf which might make that relicensing/cross-licensing process simpler.
- robertlagrant 3y agoMight depend on whether or not Qucs was compiled in statically. E.g. they could release an OSS wrapper around it that exposes it over ZeroMQ and then talking to it over that protocol, maybe?
- rahen 3y agoNot only that, but Qucs also has a SPICE version which sees a lot of activity, and unlike QucsStudio, is free software: https://ra3xdh.github.io https://ra3xdh.github.io It's only missing a solid components library like LTSpice has. Hopefully its library will see more contributions as it becomes more popular.
