That was my first thought however that is not the case as far as I can see:


xfce4_my_example_plugin_SOURCES = 
example_dat.h                                                    \
example_func.h                                                   \
example_images.h                                                 \
example_applet.c                                                 \
example.c                                                        \
example_processdata.c                                            \

 From example_applet.c which is the first source file entered. 
Originally I only had "xfce4_my_example_plugin_SOURCES = 
example_applet.c" since the rest would be found through that file. Gave 
the same error.

#include <gtk/gtk.h>
#include <glib-object.h>
#include <string.h>
#include <libxfce4util/libxfce4util.h>
#include <libxfce4panel/xfce-panel-plugin.h>
#include <libxfce4panel/xfce-hvbox.h>

#include "example_dat.h" /* contains all structures */
#include "example_func.h" /* contains all function prototypes used in 
this program */
#include "example_images.h"
#include "example.c"
#include "example_processdata.c"
#include "example_menu.c"

/* register the xfce plugin */

Google definitely is not my friend but thank you. Yes I know of both 
these sites, that is and Though I prefer 
to use myself as a search engine. :-)

Nothing beats a good old mailinglist though, especially if the 
information you need is not readily documented.

The reason I am asking here is that the source compiles fine. It's only 
after changing the makefiles and configure files to accomodate xfce4 
that the problems started. Which makes me believe I did something wrong 
with regards to xfce4 specific build process. I need more insight into 
that, more than I can gather from (which did help a 
lot by the way).
