g_printf

[Russell Shaw <rjshaw netspace net au>]

Hi,
When i compile a simple gtk 2.4.3 program, i get an error:

  main.c: In function `on_destroy':
  main.c:14: warning: implicit declaration of function `g_printf'
  gcc -ggdb -Wall -O0 `pkg-config --libs gtk+-2.0 glib-2.0` main.o gtkled.o -lm 
-o panel
  (4 of 5): warning: implicit declaration of function `g_printf'

In main.c, i have:

  #include<glib.h>
  #include<gtk/gtk.h>
  #include<gtk/gtksignal.h>


cat /usr/include/glib-2.0/glib.h shows there's no gprintf.h:

The only thing i'm doing different now is that i'm using a non autoconf
makefile:

-----------------------------------------------------------------------
PROJ=panel

CC= gcc

CFLAGS= -c -ggdb -Wall -g -O `pkg-config --cflags gtk+-2.0 glib-2.0`
LINKFLAGS= -ggdb -Wall       `pkg-config --libs   gtk+-2.0 glib-2.0`
LIBS= -lm

sources= main.c gtkled.c

$(PROJ): $(sources:.c=.o)
        $(CC) $(LINKFLAGS) $^ $(LIBS) -o $@
        
%.d: %.c
        @echo "Updating autodepend"
	@set -e; $(CC) -M $(CFLAGS) $< | sed 's/\($*\)\.o[ :]*/\1.o $@ : /g' > $@; [ -s 
$@ ] || rm -f $@

%.o: %.c
        $(CC) $(CFLAGS) $< -o $@

clean:
        rm -f $(PROJ) *.o

include $(sources:.c=.d)

.PHONY : clean
