[Flightgear-devel] RE: Re: easyxml.cxx tweak

[Phil Cazzola]

I can reproduce it (at least on my machine), right out of the box. I checked out a clean JSB, built it and ran with the f15 config. CVS will be giving me DOS style end of lines here.   Result: Crash. If I run dos2unix, it parses.  See below.   The error on the second run is because I did not specify an init file,   but it shows the config file was successfully read in.     $ ls -l jsb lrwxrwxrwx 1 Owner None 14 Mar 20 17:07 jsb -> src/JSBSim.exe*   $ ./jsb --aircraft=f15        JSBSim Flight Dynamics Model v0.9.10 Mar 20 2006 17:02:48             [cfg file spec v2.0]   JSBSim startup beginning ...   XML parse error: no element found Segmentation fault (core dumped)   /usr/local/source/cvs_versions/jsb/JSBSim $ dos2unix aircraft/f15/f15.xml aircraft/f15/f15.xml: done.   /usr/local/source/cvs_versions/jsb/JSBSim $ ./jsb --aircraft=f15        JSBSim Flight Dynamics Model v0.9.10 Mar 20 2006 17:02:48             [cfg file spec v2.0]   JSBSim startup beginning ...   Reading Aircraft Configuration File: f15                             Version: 2.0   This aircraft model is a BETA release!!!   This aircraft model probably will not fly as expected.   Use this model for development purposes ONLY!!!     Model Author:  Unknown   Creation Date: 2002-01-01   Version:       $Revision: 1.26 $   Description:   McDonnell Douglas F-15 Eagle     Aircraft Metrics:     WingArea: 608 .....  <snip>  .....       1 dimensional table with 2 rows.         -0.3490 -0.0688         0.8730  -0.0115     Function: aero/coefficient/Cndr   JSBSim startup complete   Could not open initialization file: src/../aircraft/src/../f15/src/../.xml Initialization unsuccessful           From: Jon S.

I recently made a fix for that. It shouldn't be a problem, anymore. But, you never know ... Jon
