Dear sir/ Madam, For one of our research papers, we have decided to use *CIL* as the instrumentation tool. For that *Ocaml* is required. Unfortunately, I am not being able to build Ocaml in Fedora 12. The respective gcc is : gcc-4.4.2. Can you please let me know what mistakes I am doing ? I did not find the help regarding fedora 12 and gcc-4.4.2 in any of the discussion forums. Here is the log of "make": ../../ocamlcomp.sh -c -warn-error A -g nat.mli ../../ocamlcomp.sh -c -warn-error A -g nat.ml ../../ocamlcomp.sh -c -warn-error A -g big_int.mli ../../ocamlcomp.sh -c -warn-error A -g big_int.ml ../../ocamlcomp.sh -c -warn-error A -g arith_flags.ml ../../ocamlcomp.sh -c -warn-error A -g ratio.mli ../../ocamlcomp.sh -c -warn-error A -g ratio.ml ../../ocamlcomp.sh -c -warn-error A -g num.mli ../../ocamlcomp.sh -c -warn-error A -g num.ml ../../ocamlcomp.sh -c -warn-error A -g arith_status.mli ../../ocamlcomp.sh -c -warn-error A -g arith_status.ml make[2]: warning: Clock skew detected.
