Given a file foo.c, with several functions defined in it, how to

Thanks.
Note that MacOS X differentiates between shared libraries (.dylib) and
loadable modules ("bundles" with any extension). You link against a
.dylib, but you cannot use dlopen() with a dynamic library. If you're
using dlopen(), then you need to use "-bundle" when creating the
shared object. The most succinct description is probably the one
provided by fink:
<http://fink.sourceforge.net/doc/porting/shared.php>
Once you modify your build tools to use the proper compiler flags,
then you'll be able to load the modules pretty easily. Panther
includes dlopen() automatically. On earlier systems you'll need to
install libdlcompat.
Hope this helps,
Chris
