Dear Madhavapeddy:
 
I used FrontC because I hope the parsing result w.r.t a C source code is represented in OCaml code.
 
I installed CIT and linked my main program with the library released in CIL.
 
My main program (main.ml) now is:
 
  open Frontc
  (* -------------------------------------- Test case for sample1.wh --------------------------------------*)
  let parse_result = Frontc.parse "/home/sand/zhuping/sample1.c";
 
The main program is successfully compiled without linking by executing: ocamlc -c -I /home/sand/cil/obj/x86_LINUX  main.ml
 
But an error occurs when I linked the related object codes together: 
 
ocamlc -o main -I /home/sand/cil/obj/x86_LINUX/ pretty.cmo trace.cmo errormsg.cmo cabs.cmo cabsvisit.cmo escape.cmo cprint.cmo patch.cmo frontc.cmo main.cmo
 
"Error while linking /home/sand/cil/obj/x86_LINUX/patch.cmo: Reference to undefined global 'Unix' "
 
I looked into the patch.ml code and found this piece of code where 'Unix' is referenced:
let gettime () : float = (Unix.times ()).Unix.tms_utime
 
 
Can anybody help me to solve this problem?
 
Thank you very much for your help:)
