Yes, that was my second example. That's not exactly what I want.

Thank you!
For the above example it's:

  $ ocamlc -for-pack Kernel.Parser -c Kernel/Parser/pdf.ml
  $ ocamlc -pack -o Parser.cmo -for-pack Kernel Kernel/Parser/pdf.cmo
  $ ocamlc -pack -o Kernel.cmo Parser.cmo
  $ ocamlc Kernel.cmo main.ml -o ap

Now the last thing is how to convince my OMakefile to do it
automatically.

Jozef
