rdynamic flag

[Fabricio Rocha <rocha_fabricio yahoo com br>]

	Bloody hell!! I went to Anjuta 1.2.4a and started a new libglade 
project. Its auto-generated main.c function was there with all this 
autoconnect stuff, ok. Then I added another C file to the project only 
for the "signal handlers", like on_button1_clicked and so on. Declared 
them at the top of this file. Compiled. The interface was loaded, but a 
test message ("Oops, nothing implemented yet!") from clicking the button 
didn´t come out, and closing the window would keep ther application in 
memory (in spite of having set gtk_main_quit for on_window1_destroy).

	Tried passing the handlers declaration to the main.c file -- same 
(no)thing happens. Tried moving those declarations to a header file -- 
nothing happened again. Tried declaring the GladeXML *xml buffer and 
GtkWidget *window1 as global -- nothing again. After HOURS of reading, 
browsing my gtk-app-devel-list archive and googling around, I found that 
from our always gentle Tristan:

     This (my best guess) is because libglade is not seeing global
symbols in your application, try compiling your program with `-rdynamic'
(I think there are other equivalent options, this one works).

Ofcourse you also have to make sure that your signal callback is
not declared static.

	So I came there at one of the (mysterious) Anjuta configuration dialogs 
and put this -rdynamics flag as a compiler option. And then... the damn 
thing worked!!

	Did/does anyone also HAVE to set this -rdynamic flag "manually" for 
libglade to work fine? Shouldn´t Anjuta (or a script called gtk-config 
or something alike, which was there for GTK 1.2 and I don´t know if it 
is there for GTK 2.0) set this flag automatically??

	Anyway, I am glad it has worked. But if you guys have any objection or 
know another solution, I would like to know it.

Thank you!
