06:20 #navit: < mcr42> someone got a minute? Need help with how to call a core function from a plugin.
06:37 #navit: <@cp15> Quick :-)
06:43 #navit: < mcr42> I'm not certain why I sometimes can't call a core function. Sometimes my plugin does compile but can't be loaded because of missing reference to a core function.
06:46 #navit: < ventYl> are you sure you compile your plugin against correct version of include files? (and everything is compiled by same version of gcc?)
06:46 #navit: <@cp15> Are you sure the function is there (is not a macro) and the function isn't declared static?
06:49 #navit: < mcr42> yes, I took care of that. With the current function I got it working somehow now, but I don't know what didn't work and how I fixed it ;-(. Just to make sure I'm not missing something, shoul I be able to call (non-static) core functions from a .so without problem?
06:52 #navit: < mcr42> Should there be a problem when calling core functions from a different thread? (Doing a map update in a background process and need to navit_draw() and route_update() afterwards)
06:54 #navit: < ventYl> if you can't load plugin because of missing references then call from different thread isn't your problem (yet)
06:55 #navit: < mcr42> yes, these two problems are not directly connected.
06:59 #navit: <@cp15> Navit is not thread safe, so make sure there is only one thread running in the core (it doesn't need to be the always the same)
06:59 #navit: <@cp15> What error message(s) do you get?

07:03 #navit: < mcr42> it just crashes on me. ;-( For the time being, I do event_add_timeout() in the main thread and wait for a signal var to be set from the worker thread.
07:07 -!- Usul1 [~matthias@stw-103-017.ras.uni-rostock.de] has quit [Ping timeout: 268 seconds]
07:07 #navit: < ventYl> how does it crash?
07:11 #navit: < mcr42> Can't say currently, because of my workaround. should I try to reproduce it?
07:12 #navit: < ventYl> it would be nice to know what makes it crash. if it's unresolved symbol while loading .so and navit plugin loader results in shutdown or it's segfault somewhere in loading proc. turn on coredump and look at it post mortem
07:32 #navit: < mcr42> no, it only crashed when I called the core functions from my worker thread. should not be a problem with the plugin loader or so, rather with broken pointers.

08:03 #navit: < ventYl> mcr42: pointers should be okay if your plugin was loaded correctly
08:03 #navit: < ventYl> dynamic loader is responsible for function pointer matching so either it "finds" all functions properly or reports unresolved symbols
08:05 #navit: < mcr42> OK, I reproduced it. When I try to update the view from the worker thread, the X complains about 'BadIDChoice (invalid resource ID chosen for this connection)', which ends the program. (using internal GUI on Debian VM).
08:09 #navit: < ventYl> so, you probably called update function with some bad parameter (i don't know much about it's internals) or you encountered some bug
08:12 #navit: < mcr42> well, when I do the same from the core thread, it works flawless.
08:15 #navit: < ventYl> well, cp15 wrote "Navit is not thread safe"
08:16 #navit: < ventYl> BadIDChoice is somewhat usual Xlib & co message telling you that you hit it from wrong thread
08:26 #navit: < mcr42> Thought so. Se event_add_xxx is the way to go. Is there a better way than event_add_timeout with 1second ?
09:14 #navit: <@cp15> Try it with 0 second
09:14 #navit: <@cp15> It will act immediately when the main program is idle
09:25 #navit: < mcr42> really? nothing clever like defining a new event_signal and wait for it? ;-) Ok, I'll do that.

14:28 #navit: < Usul1> I'm looking at ticket #1005 that is about boundaries and why nacit seems to have problems to find the right boundaries for suburbs
14:28 #navit: < Usul1> http://trac.navit-project.org/ticket/1005 So do we allready support boundaries?

20:03 #navit: < MMlosh> Hello..  I installed navit on andoid 2.3  It is mute
20:04 #navit: < MMlosh> system-setting->voice input and output->speech synthesis -> "play sample"  works correctly
20:05 #navit: < MMlosh> (PicoTTS)
20:05 #navit: < MMlosh> System language is set to Czech, Pico language is set to British
20:12 #navit: < MMlosh> Allright..  I chose "apply to all aplications", now it speaks..
20:13 #navit: < MMlosh> but I think it's trying to speak  Czech, which the TTS doesn't know
20:16 -!- drlizau [~liz@billiau.net] has joined #navit
20:33 #navit: < MMlosh> oh well.. I guess I'll teach the TTS to speak Czech or install a czech TTS instead..
