In file included from gui/gui.c:1:
gui/gui.h:3:21: etk/Etk.h: No such file or directory
gui/gui.h:4:19: Ecore.h: No such file or directory
Daraus folgen dann natürlich Fehler...

Aber wenn ich's per Hand mach: 
  gcc -o bla gui.c splash.c ../main.c `etk-config --libs --cflags`
Läuft es durch?!


gui.h
#include <stdio.h>
#include <stdlib.h>
#include <etk/Etk.h>
#include <Ecore.h>

void gui(void);
void _quit_app(void *);
void show_status(char *);
int  pbar_update(void *);
void splash_window_show(Etk_Widget *, char *);

static Etk_Widget *_notebook_page_themes();
static Etk_Widget *_notebook_page_static_bg();
static Etk_Widget *_notebook_page_anim_bg();
Etk_Widget *status_label;
Etk_Widget *main_window;


Das Ganze hat so funktioniert, bis ich die Funktionen in 2 Files aufgeteilt habe...
