CCS/TMS320F28027F: error with CRC function in code composer studio

Tool/software: Code Composer Studio

i am using C2000 PICCOLO Launchpad for serial communication.I am using CRC function as a part of my program.when i try to run it in C compiler,its working fine.But in CCS environment,its showing 6 errors.

1.errors encountered during linking; "Example_F2802xScia_FFDLB.out" not errors encountered during linking; "Example_F2802xScia_FFDLB.out" not    redesigned             C/C++ Problem
2.gmake: *** [Example_F2802xScia_FFDLB.out] Error 1    redesigned             C/C++ Problem
3.gmake: Target 'all' not remade because of errors.    redesigned             C/C++ Problem
For the remaining three errors its showing null there but when we click the error its directing at memory section  such as

   ramfuncs         : >> RAMM0 | RAML0,      PAGE = 0

    .text            : >> RAMM0 | RAML0,      PAGE = 0
   .cinit           : >  RAMM0 | RAML0,      PAGE = 0

i am new to this controller and ccs environment also . so please provide some references to solve these issues.
