In order to run Crazyfly python client (CFClient) some prerequisite have to be installed.
# pacman -S python2 python2-pygame python2-pyqt4
Install libusb from AUR
# yaourt -S python2-pyusb
Also, if you want to get the sources directly from the repository, buy mercurial.
# pacman -S mercurial $ hg clone https://bitbucket.org/bitcraze/crazyflie-pc-client $ cd crazyflie-pc-client $ python2 bin/cfclient
When using Arch Linux, its sometimes required to run something in a older/stable releaes of a Linux distribution. For this purpose I have a Ubuntu 12.04 LTS installation in a schroot environment. However, using Bitbake (a heavily multithreded and Python based build utility) The build aborted with the error:
File "/usr/lib/python2.7/multiprocessing/queues.py", line 63, in __init__
self._rlock = Lock()
File "/usr/lib/python2.7/multiprocessing/synchronize.py", line 147, in __init__
SemLock.__init__(self, SEMAPHORE, 1, 1)
OSError: [Errno 13] Permission denied
Gnome 3.10 on Wayland
Gnome 3.10 has initial Wayland support and hit the Arch Linux repositories lately, time to give it a try! The gnome packages are available with Wayland support, namely gnome-shell (which includes the gnome-shell-wayland binary) and mutter-wayland.
But I soon realized, that running Gnome on Wayland using Arch is not possible without some work: Firing up mutter-launch with the gnome-shell-wayland, lead to this error:
$ CLUTTER_BACKEND=wayland mutter-launch --verbose -- gnome-shell-wayland --wayland ... (gnome-shell-wayland:18781): mutter-ERROR **: Spurious exit of X Wayland server
Gnome (or more specific, mutter, the Gnome window manager/compositor) needs a working XWayland version. XWayland is a X-Server running as a Wayland client. Its only used for non Wayland compatible clients, but is a mandatory requirement for mutter right now. The X-Server in the Arch repositories does not support this mode, hence another package is necessary. Read more »
