Compiling PJSIP sample Gui application

[Paul Klose]

In hopes that this group is somewhat still alive I'll ask here for input. I compiled pjsip and am now trying to use the sample gui application

however I get following output that I don't understand. It also seems that no one has posted a similar issue around the web, so I came here since this seems to be the only kind of technical forum in existence. 

Can someone give me any pointers?
