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 you built from git then please tell us which commit hash you used. Mraa no longer tags itself as 'dirty' if built as a non tagged version but simply uses the latest version number listed in the top level CMakeLists.txt file. Note that you may have to wipe the build/ dir for git sha version to be absolutely correct.
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.
