Thanks Danielle. Almost there :) I forgot to specify the exact link <a href="http://cgit.freedesktop.org/telepathy/telepathy-doc/tree/docs/examples/glib_mc5_presence_app">http://cgit.freedesktop.org/telepathy/telepathy-doc/tree/docs/examples/glib_mc5_presence_app</a> Compiling "example.c" requires object for "connections-monitor.c" first. So, using your technique on "connections-monitor.c", I get the following dump :: ##################################################################################################### [ajay@localhost telepathy]$ gcc -o connections-monitor `pkg-config --cflags --libs telepathy-glib` connections-monitor.c connections-monitor.c:4:25: fatal error: marshallers.h: No such file or directory compilation terminated. ##################################################################################################### However, there isn't any "marshallers.h" at the link, nor is it immediately apparent as to what (package) may contain this. Any quick help in this regard ;-) ?
