I've included STM32_USB-FS-Device_Driver in my project. When I compile (in IAR) I get a bunch of errors

Error[Li006]: duplicate definitions for 'Receive_Buffer'; in 'F:\MotorControlSolution\MultiAxisMotorControl\AxisManager\Firmware\STM32F303VC\Debug\Obj\usb_core.o', and 'F:\

What is wrong?

True, but exactly the same applies whether the 'object' is code or data : there must be exactly one definition - no more, no less.

Hence there is no 'perhaps'  about the fact that the symbol (whether it refers to code or data) is being defined in 2 places.

And both of the 2 places are clearly identified.
