  • Installation paths

    From Alec Leamas@21:1/5 to All on Fri Jun 3 13:10:01 2022
    Dear list,

    This issue was started on debian-devel. However, this list is perhaps a
    better choice (?)

    I try handle a package which installs a partly compiled,
    architecture-dependent python module. That is, besides some normal
    python files it also contains a compiled, architecture-dependent so-file
    which is imported by the python files.

    Until now this has been installed in /usr/lib/triplet/python3.10/site-packages. This scheme has basically
    worked fine.

    However, here is an Ubuntu bug [1] where a user runs into problems
    because this installation path is not in sys.path by default.

    I have been trying to look in the python policy docs, but cannot find
    the exact way to install code like this.

    Any thoughts out there?

    Cheers!

    PS: I messed up the subscription, this is message is possibly
    duplicated. Sorry in that case. DS

    The correct installation location depends on whether it's a private or public module.

    If it's a private module of your application (not intended to be used by
    other apps), then you should use a private path like described in our Python Policy:

    https://www.debian.org/doc/packaging-manuals/python-policy/#programs-shipping-private-modules

    Something like /usr/lib/lirc or /usr/lib/<triplet>/lirc should work. But
    then you should also modify the application itself to add that location to sys.path.

    If it's a public module that may be used by other applications, then you
    should install to /usr/lib/python3/dist-packages (without the <triplet> part).

    You can install to /usr/lib/python3.10/dist-packages if you want, then dh_python3 will move from python3.10 to python3.
