I'm trying to make a gtk application which I have online at https://github.com/echoline/planner-desktop
the problem is on line 84 at: https://github.com/echoline/planner-des ... nner.c#L84
when I try to access the private structure associated with a widget in a certain function, it segfaults. I wonder if there's a linker option I need to use, but I can't figure this out.
the line it crashes on is:
GtkPlannerPrivate *priv = GTK_PLANNER_GET_PRIVATE (planner);
in the save function.
please let me know if there's more information I can provide to get help with this.
