Hi,
I've cross compiled clutter 0.8 and its dependencies for an arm platform.
It's working but when I try to create a label in my application I get a
crash :
./SimpleText
*** glibc detected *** ./SimpleText: munmap_chunk(): invalid pointer:
0x000827e8 ***
======= Backtrace: =========
/lib/libc.so.6[0x40a57af4]

./SimpleText(FcConfigSubstitute+0x30)[0xfdc0]
/opt/pango/lib/libpangocairo-1.0.so.0[0x40211f8c]
I've configured fontconfig : fc-match,fc-cache, fc-cat and fc-list are
working. Fontconfig and it's subdirs are in /opt but I've specified the
correct path in LD_LIBRARY_PATH.
Here you can take a look at the code, it's writen in vala, if you need the C
generated code tell me :
using GLib;
using Clutter;
public class SimpleText : GLib.Object {
private Clutter.Stage stage;
construct {
Clutter.Color actor_color = {(uchar) 0xff, (uchar) 0x00, (uchar)
0xaa, (uchar) 0x99};
this.stage = (Clutter.Stage) Clutter.Stage.get_default ();
this.stage.set_size (800, 480);
this.stage.show ();
Clutter.Label label = new Clutter.Label.full ("Sans 12", "Hello !",
actor_color);
label.set_position (50, (int) this.stage.get_height () - (int)
label.get_height () - 50);
this.stage.add_actor (label);
label.show ();
}
public static void main (string[] args) {
Clutter.init (ref args);
SimpleText text = new SimpleText ();
Clutter.main ();
}
}
When take a look at the program with gdb I can see the crash happens with
"clutter_actor_set_position" :
clutter_actor_set_position ((ClutterActor*) label, 50, (((gint)
clutter_actor_get_height ((ClutterActor*) self->priv->stage)) - ((gint)
clutter_actor_get_height ((ClutterActor*) label))) - 50); // this is C
generated code
There is details :
70 clutter_container_add_actor ((ClutterContainer*)
self->priv->stage, (ClutterActor*) label);

I hope someone will have an idea of what I can do to solve this problem and
display text with clutter.
Thanks,
