Error Linking TI Fee Driver with Hercules RM46

Other Parts Discussed in Thread: HALCOGEN

Hi,

I am trying to utilize the TI Fee driver for the Hercules RM46. I have enabled the driver in HalCoGen and added the Flash API library and include directory into my compiler and linker include sections for my CCS project. When I attempted to build the project I get a linker error saying:

 undefined                       first referenced     
  symbol                             in file          
 ---------                       ----------------     
 TI_Fee_Init()                   ./source/sys_main.obj
 TI_Fee_GetStatus(unsigned char) ./source/sys_main.obj

 TI_Fee_MainFunction()           ./source/sys_main.obj
>> Compilation failure

error #10234-D: unresolved symbols remain
error #10010: errors encountered during linking; "PC Interface.out" not built
gmake: *** [PC Interface.out] Error 1
gmake: Target `all' not remade because of errors.

Any ideas what could cause this? I have attached my CCS and HalCoGen Projects for review.

Thanks,

Got it. I needed to do:

extern "C"
{
    #include "ti_fee.h"
}

Since I was using the C++ compiler.

Thanks for the link. That's actually what gave me the idea. Just to make sure I understand what happened here, because the FEE driver uses the prebuilt F021 library, which is compiled in C, the C++ compiler mangles the functions declared in the headers and the cannot find the symbols for them. Correct?
