Error: unable to open executable

When I’m trying to compile my game, I get following error message:

I’m using a iMac (27-inch, Late 2013) with 3,2 GHz Intel Core i5 and NVIDIA GeForce GT 755M 1024 MB and my operating system is OSX 10.10.5 (14F27)

Don’t worry! 99% chance it’s just a bug in your code! Try disabling different parts of your code to try to narrow down the possibilities of where the bug could be.

Hopefully you’ve already figured this out… This should be useful for anyone who come across this via google…
