Linking error during project building in CCS

Hi All,

Can any one suggest about below error?

<Linking>

fatal error: file "C:/Program Files/Texas Instruments/C5500 Code Generation

   Tools 4.3.7/lib/rts55h.lib<exit.obj>" has a Tag_Memory_Model attribute value

   of "3" that is different than one previously seen ("1"); combining   incompatible files

Thanks in advance,

Ashwin Panchal
