build failing after pull

[evainga]

@mle-enso, I merged your pull request after I added my showSpecificEvent changes and didn't realize thet the master was red after that... I am trying to fix it and might not be too far away from the solution but I cant totally figure it out... Maybe we can have a look at it together tomorrow...

Did you compile your code before committing? I would suggest the patch below.
