Hey, so I went to open up my competition code and for some reason the compiler said that:
File “.\Includes\Vex_Competition_Includes.c” compiled on Nov 10 2016 16:03:39
Error:No body defined for procedure prototype ‘usercontrol’
Warning:Unreferenced function ‘pre_auton’
Warning:Unreferenced function ‘UserControlCodePlaceholderForTesting’
Warning:Unreferenced function ‘AutonomousCodePlaceholderForTesting’
and I don’t know how to fix it. Can someone please help me?

That code above is a mixture of the Vex_Competition_Includes.c file (which is a system file and you should not edit) and a competition template. The competition template is opened from the file->new menu and looks like this.

See if you can open the template and compile it.

If the robotc Vex_Competition_Includes.c file has been edited for some reason you will need to replace it with the original file that we provide as part of the installation, the easiest way would probably be to uninstall and then reinstall robotc.
