CCE and Redefine Error during Code Port

Other Parts Discussed in Thread: MSP430F249

I am working on porting code from an NEC chip to the MSP430F249. I am using CCE 3.2.2.1.8. During the "Linking" of the project, I receive several of the following errors for numerous functions that are declared. I imagine it has something to do with the fact that las.obj has the "comm_xmt_str" function already linked into it through a header file, but why is it choking when system.obj is linked. I know "xxx.h" files are included throughout the various files, but why is this causing an error? Is there any way to ignore this through the Linker setup.

error: symbol "comm_xmit_str" redefined: first defined in "./LAS.obj"; redefined in "./SYSTEM.obj"

    This error is typically generated when the symbol has been defined in multiple source files. Where is "comm_xmit_str" defined, in a source file or a header file? Could you send code snippets of these 2 source files and what the build command looks like in the CCE build window?

    I think you might have triggered a thought. It looks like all the functions this error is occurring on are ones that I have implemented a return call within the header file so I can slowly migrate each of the corresponding C files over. So for the comm_xmt_str function I have placed the following line in the comm.h header file to at least implement the function but not allow any erros.

    int

    comm_xmit_str (enum CommPort Port, char *buff){return(1);}
