Chief Delphi - FRC_userClassFactory

Hi,
What is the FRC_userClassFactory? When I loaded code onto the robot, it complained about this error:

Code:

* Loading StartupDLLs: FRC_UserProgram

Warning: module 0xe7bb90 (FRC_UserProgram.out) holds references to undefined symbol _GLOBAL__D__Z20FRC_userClassFactoryv.

Warning: module 0xe7bb90 (FRC_UserProgram.out) holds references to undefined symbol _GLOBAL__D__Z20FRC_userClassFactoryv.

(unloading partially loaded module FRC_UserProgram.out)

...FRC_UserProgram.out failed to load.

Is this part of WPILib?

Thanks!
