Hello again:
I 'am trying to compile the GTK samples of the site but the following occurs:

linx:~/gtk-examples/gtk-window # make
fasm window.asm window.o
flat assembler version 1.67.14 (16384 kilobytes memory)
2 passes, 609 bytes.
gcc -Wall -s -O3 window.o -o window `gtk-config --cflags` `gtk-config --libs`
/bin/sh: gtk-config: command not found
/bin/sh: gtk-config: command not found
window.o: In function `main':
: undefined reference to `gtk_init'
window.o: In function `main':
: undefined reference to `gtk_window_new'
window.o: In function `main':
: undefined reference to `gtk_widget_show'
window.o: In function `main':
: undefined reference to `gtk_main'
collect2: ld returned 1 exit status
make: *** [window] Error 1

I do not understand because I have Instaled Anjuta and Glade and works perfectly. Can somebody tell me what happens?. Thanks from now
Luis Enrique

you need to install gtk development library

more from functions you will find into usr/lib/libgtk-x11-2.0.so.0 (in ubuntu 6+)
compile with: cc window.o /usr/lib/libgtk-x11-2.0.so.0 -o window -Xlinker "-s"
