Building Libtool-made shared libraries is quite simple.  Suppose you
want to create `libmy-guile-ext.so' (or `libmy-guile-ext.sl' on HP-UX,
etc.).  All you need to do is put the following in your `Makefile.am':

  # `.la' is the extension for Libtool's ``pseudo-libraries''
  lib_LTLIBRARIES = libmy-guile-ext.la
  
  libmy_guile_ext_la_SOURCES = chbouib.c foo.c bar.c
  libmy_guile_ext_la_LDADD = -lsmurf -lm

And that's it.  See [0,1] for details.

Then you need to create some `my-guile-ext.scm' module that will load
the extension library using `dynamic-link' and `dynamic-call' (both of
which are described in Guile's manual I think).

Thanks,
Ludovic.
