You guessed wrong ! The *_p.a libraries are used for profiling.
Try using the normal libraries: -lgr  or  -lgrx
Make sure to have 'extern "C"' statements around your include files
inside your sources to avoid C++ name mangling, just in case...
(Most include files have these already, I assume)

  #ifdef __cplusplus
  extern "C" {
  #endif

  #include <graphics.h> (or #include <grx.h>)

  #ifdef __cplusplus
  }
  #endif

Try: -lpc
