a2j_control fails because dbus is not in the python path

[svenkeidel]

a2j_control is an executable of the a2jmidid project. The exact error message is

Traceback (most recent call last):
  File "/home/sven/.nix-profile/bin/a2j_control", line 11, in <module>
    import dbus
ImportError: No module named dbus

I suggest changing stdenv.mkDerivation to buildPythonPackage and add pythonDBus to the pythonPath. @cillianderoiste can you please comment on my suggestion?

Best,

@svenkeidel I don't think you can use buildPythonPackage for this one since it actually uses waf for building and installing (rather than the setup.py). How about just wrapping a2j_control with the relevant python modules?

[svenkeidel]

Whatever works.

Have a look at the nix package for jack, they use wrapProgram:

wrapProgram $out/bin/jack_control --set PYTHONPATH $PYTHONPATH

[cillianderoiste]

Exactly, can you test that out and open a PR?

Thanks for the discussion, the PR is #6931,
