CCS/TMS320F28374D: Symbol redefined: first defined in

Tool/software: Code Composer Studio

Hi there,

I'm working with CCS8.3 and I incldued into my project some header and source file provided by HMS for an SPI Communication Module.

When I compile the project I get this error:

"Description    Resource    Path    Location    Type
symbol "_RunShutdownSocketInterfaceSM" redefined: first defined in "./appl_abcc_socket_shutdown.obj";
redefined in "./driverlib/abcc/appl_abcc_socket_shutdown.obj" null: symbol "_RunShutdownSocketInterfaceSM" redefined: first defined in "./appl_abcc_socket_shutdown.obj";
redefined in "./driverlib/abcc/appl_abcc_socket_shutdown.obj"    cpu01             C/C++ Problem"

The symbol "RunShutdownSocketInterfaceSM" is defined into an header file as:

EXTFUNC void RunShutdownSocketInterfaceSM ( int *status );

And defined in another C file file as

EXTFUNC void RunShutdownSocketInterfaceSM ( int *status );

and into the same file the function is implemented

void RunShutdownSocketInterfaceSM( int *ShutdownStatus )
{
  ...
}

This is how EXTFUN is defined

#ifdef __cplusplus
   #define CPLUSPLUS
#endif

#ifdef CPLUSPLUS
   #define EXTFUNC extern "C"
#else
   #define EXTFUNC extern
#endif

The source and header file are placed inside a project folder and they are linked into the project.

I'm struggling with this error.

Can anybody help me?

Thanks in advance for your time.

Best regards,

Federico
