Warning: long append
The problem with help on mac os x (possibly other platforms) --
<http://mail.flightgear.org/pipermail/flightgear-devel/2005-November/
040462.html> -- is still occurring.
somehow something is switching /sim/startup/browser-app from "open"
after it is set in Main/options.cxx, but before options are processed
from the command line
(help works if I start fgfs with --browser-app="open")
I am using the following arguments to fgfs to generate a log to
examine the problem:
--log-level=info --trace-write=/sim/startup/browser-app --trace-read=/
sim/startup/browser-app
Using grep on the source tree, I see the following /browser strings:
[/src/fgdev9.9] ima% find . -name '*.[ch]xx' -print | xargs grep $1 /
dev/null
./src/FlightGear/src/GUI/gui_funcs.cxx: string help_app =
fgGetString("/sim/startup/browser-app");
./src/FlightGear/src/Main/options.cxx: fgSetString("/sim/startup/
browser-app", "webrun.bat");
./src/FlightGear/src/Main/options.cxx: fgSetString("/sim/startup/
browser-app", "open");
./src/FlightGear/src/Main/options.cxx: fgSetString("/sim/startup/
browser-app", "launchWebJumper");
./src/FlightGear/src/Main/options.cxx: fgSetString("/sim/startup/
browser-app", envp);
./src/FlightGear/src/Main/options.cxx:// SG_LOG( SG_GENERAL,
SG_INFO, " help app is " << fgGetString( "/sim/startup/browser-app" ) );
./src/FlightGear/src/Main/options.cxx: SG_LOG( SG_GENERAL,
SG_ALERT, " help app is " << fgGetString( "/sim/startup/browser-
app" ) );
./src/FlightGear/src/Main/options.cxx: {"browser-
app", true, OPTION_STRING, "/sim/startup/browser-
app", false, "", 0 },
The tracing functions aren't seeing ANY changes to /sim/startup/
browser-app (from the log I guess they start after
/sim/startup/browser-app is set in Main/options.cxx, but these
functions are not seeing any changes after they start
either.)
By the time the app is up and running and I select Help from the Help
menu, the value has been changed
(it should be open on mac os x, but is netscape which is not
installed on the system).
Does anyone have any suggestions on how to explore the problem in gdb
to see what is going on? Where is a value like /sim/startup/browser-
app stored in memory
in a running copy of fgfs? Any suggestions on which property
functions to look at?
Thank you
Ima
