Low Level Skeleton Library for Communication on GNU/Linux platforms
This page contains a few debugging tip. When filing an issue please go through this list as it's the first thing we'll ask you to do.
Getting the exact version of libmraa you're running is really important to us. The best way to get this is to call mraa_get_version() or mraa.getVersion(). If mraa returns x.x.x-dirty then your version was not built from a git tree or you built out of tree (see our building doc) - or you don't have git installed.
mraa logs pretty much everything that goes wrong to syslog. These days it'll go to the systemd journal so check with
sudo journalctl -f whilst running your app or check all libmraa messages with
journalctl -t libmraa. Grab all the messages from the initialisation message right up to your last one. Using a pastebin is always a good idea, I like dpaste.com. If your system does not have systemd likely your log is in /var/log/messages or a similar location.
