CCS/TMS320F28054F: eCAN structs are unresolved symbols in Instaspin project

Tool/software: Code Composer Studio

I'm working on integrating eCAN into a modified version of lab 5b of the Instaspin FOC labs. I added a file can.c in the same location as the can.h header file (sw/drivers/can/...../src). In order to test it in the simplest form, can.c ONLY includes this:

//
// Included Files
//
#include "sw/drivers/can/src/32b/f28x/f2805x/can.h"

// Prototype statements for functions found within this file.

void CAN_init(void)
{
    ECanaRegs.CANAA.all = 0;
    return;
}

I've simplified my main method as well temporarily to only include a call to CAN_init(). ECanaRegs is defined in can.h and I can right click -> open declaration to be taken there. The error I'm getting tells me that ECanaRegs is an unresolved symbol (same for ECanaMboxes or the shadow register when I call them). When I comment out that definition, I get a different error (ECanaRegs undefined), so I know that it can see the can.h file.

Before I had another file from c2000 (f2805x_eCAN.h) which included the same definitions, but I have removed that completely from the project. I get the same "unresolved symbol" error when I call these structs from the main method? What's wrong?

Thanks
