Hey, I was following this tutorial:

got to the bit where you first compile and it comes up with this:

Setting up Mono  
Building FPSShooter…  
Compiling with Mac SDK 10.10  
ERROR: Source file “/Volumes/1TB/Game work/Freelance Work/MythRealm Games/FPSShooter/Source/FPSShooter/.\_FPSGameMode.cpp” is not including any headers. We expect all modules to include a header file for precompiled header generation. Please add an #include statement.  
Command /Users/Shared/UnrealEngine/4.6/Engine/Build/BatchFiles/Mac/RocketBuild.sh failed with exit code 2

It happens when i try to use the templates as well.

I dont have a clue. haha

Edit: it also says that the generated header file does not exist
