Hi,
I am using the latest trunk version of clutter (I did a fresh Linux
install on new laptop). Somehow clutter_label causes any clutter
program to crash. For example the tutorial:
(Here is a version with debug texts)
#include <clutter/clutter.h>
#include <stdlib.h>
int main(int argc, char *argv[])
{
ClutterColor stage_color = { 0x00, 0x00, 0x00, 0xff };
ClutterColor actor_color = { 0xff, 0xff, 0xff, 0x99 };
printf("clutter init\n");
clutter_init (&argc, &argv);
/* Get the stage and set its size and color: */
ClutterActor *stage = clutter_stage_get_default ();
clutter_actor_set_size (stage, 1000, 1000);
clutter_stage_set_color (CLUTTER_STAGE (stage), &stage_color);
printf("stage done and color set\n");
/* Add a rectangle to the stage: */
printf("rectangle\n");
ClutterActor *rect = clutter_rectangle_new_with_color (&actor_color);
printf("rectangle done\n");
clutter_actor_set_size (rect, 100, 100);
clutter_actor_set_position (rect, 20, 20);
clutter_container_add_actor (CLUTTER_CONTAINER (stage), rect);
printf("show rect\n");
clutter_actor_show (rect);
// #ifdef huuhaa
printf("label\n");
/* Add a label to the stage: */
ClutterActor *label = clutter_label_new_full ("Sans 12", "Some
Text", &actor_color);
clutter_actor_set_size (label, 500, 500); /* TODO: Has no effect
yet. See bug #631. */
clutter_actor_set_position (label, 20, 150);
printf("label add to container\n");
clutter_container_add_actor (CLUTTER_CONTAINER (stage), label);
clutter_actor_show (label);
// #endif
printf("show stage\n");
/* Show the stage: */
clutter_actor_show (stage);
printf("clutter_main()\n");
/* Start the main loop, so we can respond to events: */
clutter_main ();
printf("clutter main quitted\n");
return EXIT_SUCCESS;
}
What happens is:
[EMAIL PROTECTED]:~/work/clutter/clutter-tutorial/examples/actor$
./example
clutter init
stage done and color set
rectangle
rectangle done
show rect
label
label add to container
show stage
Floating point exception (core dumped)
If I comment out one line, this:
clutter_actor_show (label);
and then compile and run again, it does not crash.
Here is the output from gdb:
