Subject: Re: Signal 4 running gtk-demo
To: directfb-users@directfb.org
I trace the problem to
data->pipe_thread = direct_thread_create( DTT_MESSAGING,
IDirectFBEventBuffer_Feed, data,
"EventBufferFeed" );
on IDirectFBEventBuffer_CreateFileDescriptor (src/input/idirectfbinputbuffer.c)
The specific problem is after the thread is created, exactly in the point where will be executed the function
ret = thread->main( thread, thread->arg );
on direct_thread_main (lib/direct/thread.c) directfb hangs
If i put a sleep just before ret = thread->main( thread, thread->arg ); gtk-demo loads ok (also if i comment direct_thread_create) but this left me without mouse (i don't test the keyboard).
IDEAS PLEASE!!!!!!
