Re: [Flightgear-devel] ANN: New Menu Bar; dialogs for clouds,winds, and air
David, With the new Air dialog box, I'm running into a segfault. What I do to trigger the crash is first bringe up the Air dialog box, then I examine the data and decide I don't want to change anything, then I click ok. The back trace lists a bunch of internal PUI calls and then dies in GUI/dialog.cc:action_callback(), specifically at line #24. I'm guessing that info-bindings[i] doesn't have a valid object so when it tries to call the fire() method it segfaults. Is that enough for you to go on, or should I dig deeper and find additional info for you? I'm getting this exact same behavior all three weather dialog boxes.

Typically you run fgfs from within gdb. Something like bash$ gdb fgfs gdb run --fgfs-option1 --fgfs-option2 Then when you get a crash you can type: gdb where To get a back trace. Regards, Curt.

RE: [Flightgear-devel] ANN: New Menu Bar; dialogs for clouds, winds, and air
Curt, David I already messed a bit around with gdb, but it always died. Mean issue was I set --fg_root= instead of fg-root= :-((( It now does run. However, after selecting the button in question, flightgear never dies completely. Instead, it hangs infinitely. I had to kill it manually. The trace did not say much $ where __: not found This: not found __: not found The: not found http://www.cdrom.com/pub/infozip/doc/WHERE: not found Note: not found and: not found /cygdrive/c/bin/where: 12: Syntax error: word unexpected (expecting )) - However, I made another run using the graphical GDB frontend. FG hangs again, but I find from the graphical window it's in dialog.cxx, line 26 (something with the new GUI). Maybe this helps: -- - 23-get_group(FGSubsystemMgr::INIT)-get_subsystem(gui); - 24 gui-setCurrentWidget(info-widget); - 25 for (int i = 0; i info-bindings.size(); i++) - 26 info-bindings[i]-fire(); - 27 gui-setCurrentWidget(0); -- Regards, Michael -- Michael Basler, Jena, Germany [EMAIL PROTECTED] http://www.geocities.com/pmb.geo/ ___ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel
