non trivial (at least not to me) Hybrid program compiling

Hello, i'm trying to make a OCaml binding to C library PCSCLite, and i'm not
being able to compile it, because for instance, when i try to compile the
pcsc_demo.c provided by MUSCLE i do the folowing steps:

cc `pkg-config libpcsclite --cflags` -c pcsc_demo.c
cc `pkg-config libpcsclite --libs` -o pcsc_demo pcsc_demo.o

then when i try to compile my own program i can make the 1st step as above,
only ading the OCaml lib path:

cc `pkg-config libpcsclite --cflags` -I/usr/lib/ocaml -c testC.c

but the problem comes when i have use the OCaml compiler to link to my OCaml
and C parts, i tried (with variations):

ocamlopt `pkg-config libpcsclite --libs` -o test testC.o testML.ml

but i get an option usage error...

The error is preaty explicit so i'm not obeying the compiling rules, but i'm
not geting how i'm gonna add the `pkg-config libpcsclite --libs` part,
because if i dont the C API wont be recognized by the OCaml linker...

Thank You
Manuel

You want to use the --ccopt and --cclib flags to pass the options to
the C compiler; e.g:

ocamlopt -cclib `pkg-config libpcsclite --libs` -o test testC.o testML.ml

or

ocamlopt -ccopt `pkg-config libpcsclite --cflags` -o test testC.c testML.ml

HTH.
