[L2Ork-dev] Linux dependencies in README.md build guide

Fri Oct 9 00:15:24 EDT 2020

Thanks, Ico.

Yes, it seems that cwiid is the one which needs it. Looking at the source
code in externals/disis/cwiid, there's a configure script there which
checks for Python, and a septup.py script that gets run during the build.
There's no actual Python C API code being linked there, as far as I can
tell. But from unsuccessful OBS builds I know that it will fail with an
error when running configure and Python is not installed, and I also seem
to recall that Python3 didn't work either, it really needs Python2 for some
reason. Unfortunately, the OBS doesn't keep logs of older builds, so all
this is from the top of my head, but that's how I remember it.

Talking about this external, can anyone running a *current* Linux system
(Arch or Ubuntu 20.04+) with a recent Bluez 5 version confirm that
disis_wiimote still works there? I'm asking because I could never make it
work, it just doesn't find my Wiimote (which works fine with the xwiimote
kernel driver). If I'm not mistaken, disis_wiimote still employs some user
space drivers and utilities which aren't supported in Bluez 5 any more. But
if anyone has it actually working on Bluez 5 then I'd really like to hear
about it!

Thanks,
Albert
