The problem was that I didn't know enough about automake. You need to be very careful in modifying Makefile.am. Some extra examples would have been very helpful. To that end I have attached the Makefile.am that I use to compile two plugins sample and classify. My initial procedure was :- git cd gst-template/gst-plugin/src ../tools/make_element classify ../tools/make_element sample gedit Makefile.am cd .. ./autogen.sh make I have been unable to generate any plugins from the gsttransform template. If I do ../tools/make_element classify gsttransform then make produces lots of errors If I change the #include "gsttransform.h" in gstclassify.c to #include "gstclassify.h" the make compiles ok but when I try to use the plugin, it fails saying "gst_object_sync_values is undefined". Any ideas what I'm doing wrong? JC </div></div> </body></html>
