Hi,
I'm having trouble (cross) compiling gtk with the directfb frontend.
(I have asked the same question on the directfb mailing list today.)
I have basically followed the instructions on
www.directfb.org/wiki/index.php/Projects:GTK_on_DirectFB_for_Embedded_Systems
(which seems to be unavailable since a couple of days, but it's still in
google's cache).
When I compile gtk, I get a few dozen duplicate symbols, all internal
aliases of function names of the form IA__*. It looks as if some functions
in gdk/gdkwindow.c should be replaced by those in
gdk/directfb/gdkwindow-directfb.c, but the generic ones are still compiled
and linked to the libraries. The error pops up when gtk-query-immodules-*
is being built (obviouosly I didn't remove it from the Makefile as the
instructions suggested), and will also occur when I try to build test
programs.
I tried a few obvious fixes like removing the functions in question (also
from gdkaliasdef.c) or even replacing the generic file with the one in the
directfb subfolder, but then I get undefined symbols in different flavours.
I eventually just linked with -z muldefs, but then the test application
crashes with a null pointer reference in the gdkwindow vicinity which makes
me suspicious, somehow.
From what I see everybody compiling gtk/directfb should run into this
error, which is probably not the case (I found only one post with the same
problem that stayed unanswered); I'm missing something. What is it?
(I apologize for not providing the gtk configure options etc., but I'm not
at my computer today. I'm using a fairly recent gtk version, probably a
2.14.x. For what it's worth, I'm using a gcc 4.2.x on a i386 linux, target
is generic ppc, but I can't see how that should have an impact.)
Peter
