using gtk+ and pixbuf

[alternative451]

hi

//my included files
#include<gdk/gdk.h>
#include<gdk/gdkx.h>
#include <gtk/gtk.h>
#include <stdlib.h>
#include <gdk/gdkx.h>
#include<stdio.h>
a_fuction(){
GdkPixbuf *buf_pixel; // where i create a pixbuf object
}
main(){
}

//my gcc compilation line
gcc -lgdk_pixbuf-2.0 -lm main.c -o main `pkg-config --cflags --libs gtk
+`
// error
main.c:24: erreur: «GdkPixbuf» undeclared (first use in this function)
main.c:24: erreur: (Each undeclared identifier is reported only once
main.c:24: erreur: for each function it appears in.)
main.c:24: erreur: «buf_pixel» undeclared (first use in this function)


the gnome pixbuf section :
http://library.gnome.org/devel/gdk-pixbuf/stable/gdk-pixbuf-gdk-pixbuf.html
but if i include <gdk-pixbuf/gdk-pixbuf.h> gcc return no file found

I look for using a pixbuf object but i havent found how.
i don't know if it's a gcc option or in my code.

prompt -> alternative451@sylvie-desktop:~/c$ pkg-config --print-errors
--cflags --libs gtk+

return -> -I/usr/include/gtk-1.2 -I/usr/include/glib-1.2 -I/usr/lib/
glib/include -lgtk -lgdk -lXi -lXext -lX11 -lm -lglib
haaaaaaaaaaaaa
ok i think i need -lgdk_pixbuf
but how add ?

tank you

Do you have gdk-pixbuf-config in your PATH? Try checking in /usr/X11R6/bin,

/usr/X11../bin checked -> there is a gdk-pixbuf-config

my path :
prompt -> alternative451@sylvie-desktop:~/c$ echo $PATH
return ->/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/
usr/games

    `gdk-pixbuf-config --libs --cflags`

i added this line
prompt -> alternative451@sylvie-desktop:~/c$ gcc main.c -o main `pkg-
config --cflags --libs gtk+` `gdk-pixbuf-config --libs --cflags`

return some error
-> main.c:26: erreur: «GdkPixbuf» undeclared (first use in this
function)

This is entirely off-topic on c.l.c. The only standard includes in
the above list are stdlib.h and stdio.h.

Does this mean posting code that contains any function that is not
defined in the standard is also off topic?

Yes. But note that this assertion can be simplified to the following
simple statement (which I have proven to be true many times in the
past):

Nothing is on-topic in CLC. (*)

trolling.
