I think you need a convert.m4 file, which includes the others, here:

For instance:

If this fixes it, please submit a patch for the gmmproc appendix in the
book, or file a bug about it.

This works. Thanks! I'll submit a patch for the gmmproc docs.

Now there is another problem. I end up with literal _CONVERT macros inside the code which to my understanding should be post-processed again (it seems like it's a 2-stage thing where it picks up code, creates _CONVERT macros, which are then processed again).

But, the code still contains stuff like (i've prepended the namespace here, since it's Gst::Object, not Glib::Object, just making sure..):

<code>
bool Gst::Object::set_name(const Glib::ustring& name)
{
  return _CONVERT(gboolean,bool,gst_object_set_name`'(ifelse(`',1,const_cast<__CNAME__*>(gobj()),gobj())`'ifelse(`_CONVERT(const Glib::ustring&,gchar*,name,0)',,,`, ')_CONVERT(const Glib::ustring&,gchar*,name,0)));
}
</code>

The wrapper inside gstobject.hg looks like this:
<code>
  _WRAP_METHOD(bool set_name (const Glib::ustring& name), gst_object_set_name)
</code>

I have this here in gst_method.defs:
<code>
(define-method set_name
  (of-object "GstObject")
  (c-name "gst_object_set_name")
  (return-type "gboolean")
  (parameters
    '("gchar*" "name")
  )
)
</code>

And also basic conversion definitions for the basic pointer conversions inside convert_gst.m4 (which now works thanks to the previous hint, thanks again!)

_CONVERSION(`GstObject*',`Glib::RefPtr<Gst::Object>',`Glib::wrap($3)')
_CONVERSION(`Glib::RefPtr<Gst::Object>',`GstObject*',__CONVERT_REFPTR_TO_P)
_CONVERSION(`Glib::RefPtr<Gst::Object>&',`GstObject*',__CONVERT_REFPTR_TO_P)

What could be wrong?
