Thanks for the help.  Does that mean once OCaml support dynamically 
linking for native code, lablgtk will  have a new version to support 
dynamic library for native code also?

Ocaml does not currently support dynamic linking of Ocaml code
but I understand this is coming in version 3.11.

The ".a" libraries you see for liblgtk2 are the Ocaml parts of
the bindings to libgtk2 etc. The C parts of the underlying libraries
can still be dynamically linked.

For instance, ldd for an application I've written looks like this:

        linux-gate.so.1 =&gt;  (0xb7f58000)
        libgtk-x11-2.0.so.0 =&gt; /usr/lib/libgtk-x11-2.0.so.0 (0xb7bc4000)

        libXdmcp.so.6 =&gt; /usr/lib/libXdmcp.so.6 (0xb741c000)

As you can see, dynamic linking is being used for the C libraries.

HTH,
Erik
