It's not that bad. It's just shiboken2 and PySide2 for your package plus shiboken2_generator for generating the bindings. I wouldn't call this a nightmare. > Are there any shared build jobs for pyside2?

I guess you already found the docker containers provided here https://github.com/pypa/manylinux for generating binary python packages for linux. Other than that I am not aware of more resources, I think you'd have to integrate your library into a CI environment for your own. > > сб, 2 мая 2020 г. в 15:18, <ic...@gmx.net <mailto:ic...@gmx.net>>: > > Hi, > > you have to use shiboken2 for creating the bindings.
