python3 comes with python3Packages, so please drop python3 here.

Thanks for the PR. Apologies for reviewing it this late.
Could you put unittest-cpp in a separate commit and name the commits according to the contributing guidelines.

[FRidh]

oh and cc me when that's done. It looks like it is to be ready to merged then.

Hi Frederik,

python3 comes with python3Packages, so please drop python3 here.

fixed

${python3}/bin/python3 -> ${python.interpreter}

fixed

you can use here stdenv.lib.makeLibraryPath

I tried and did not figure it out. Also I haven't found any example of doing this with PYTHONPATH, it is always without makeLibraryPath.

I implemented your suggestions, built and tested openshot-qt and it worked fine. Then I rebased on top of master and after that I get the following error:

…

I have no idea what to do about this and I think this is out of scope for the openshot-qt nix package.

You're correct. I thought it could be used also for this case but apparently it can't.

Testing now.

Indeed, there is a issue with PyQt5. See #17045

Merged #16098.

Thanks a lot!
