Trying to compile a panel plugin

[Jeroen van Aart]

Hello (first post),

I am converting a gnome panel applet to xfce panel plugin. I have so far 
removed the few gnome specific parts in the source and replaced them 
with xfce specific source as appropriate.

I created makefile.am and configure.ac files using templates such as the 
weather plugin and the example plugin. However I am unsuccessful in 
getting it compiled properly. I am probably missing something obvious, 
but I double checked the examples with my own files and find no obvious 
problems.

I have attached the appropriate files as well as output of the errors in 
the hope someone has an idea. I don't think the problem is in the actual 
source, but I can add some of that later if necessary.


Errors while compiling:

SIGFILE is one of the defines in my header files. Then it goes on as if 
it never read my header files with all the declarations.

Last bit:

my_example.c:248:17: error: unknown type name ‘XfcePanelPlugin’
my_example.c:248:42: error: unknown type name ‘GtkWidget’
my_example.c:248:60: error: unknown type name ‘GtkWidget’

make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/source/my_example_xfce'
make: *** [all] Error 2

See attachment for Makefile.am, configure.ac and 
panel-plugin/Makefile.am. I generate the makefiles and configure files 
using xdt-autogen.


Thank you,
Jeroen
