Subject: [Caml-list] shared libraries [pcre-ocaml]
Hello I've some problems with ocaml and shared libraries. I'm running
a recent FreeBSD-4-STABLE and have ocaml 3.04 installed from ports.

pcre-ocaml is built with shared libraries and is installed in

ocaml's ld.conf contains the following lines:


If I use ocamlopt to compile everything is fine but when I use ocamlc
the following error occurs.

# ocamlc -o myprog -I +site-lib/netstring -I +site-lib/pcre \
         unix.cma pcre.cma netstring.cma

Error on dynamically loaded library: Shared object "" not found

I ran truss to see the syscalls made by ocamlc (relevant bit below) and
to me it seems as if it finds but not on which depends. However if I run ldconfig to include pcre-ocaml's
installation directory everything works just fine.

So, should I have to use ldconfig or is there something wrong?
