[Flightgear-devel] properties problem

2002-01-20 Thread Erik Hofman 


Hi,

The latest FlightGear from CVS gives me a core after startup.
I traced it back to SimGear/simgear/misc/props.hxx line 730:

Process 14190 (fgfs) stopped on signal SIGSEGV: Segmentation violation 
(default) at [SGPropertyNode::getAttribute(SGPropertyNode::Attribute) 
const:730 +0x10,0x103b2110]
  730  bool getAttribute (Attribute attr) const { return ((_attr  attr) 
!= 0); }

I have no idea why this happens.
Does anybody else have any idea?

Erik

 I think you need to look higher up in the call stack: perhaps the object pointer on 
which this method is called was invalid.


You are right, I forgot to mention:

I tracked the probelm down to FlightGear/src/Maim/main.cxx
SGTime *t = new SGTime( longitude-getDoubleValue()
   * SGD_DEGREES_TO_RADIANS,
 latitude-getDoubleValue()
   * SGD_DEGREES_TO_RADIANS,
 zone.str() );

Tests show that both longitude and latitude are false ...
Hope this helps some more.

I'm lost at this one :(

By false you mean they are null, I assume.  Well, latitude and longitude are 
created a few lines further up by:

// Any time after globals is created we are ready to use the
// property system
static const SGPropertyNode *longitude
= fgGetNode(/position/longitude-deg, true);
static const SGPropertyNode *latitude
= fgGetNode(/position/latitude-deg, true);

So these must be failing.  There should probably be a check for null pointers there.

[Flightgear-devel] Properties problem

2002-01-05 Thread Erik Hofman 


Hi,

Since a few days I have the following error message, and I can't find 
why ??!?

/home/erik/fgfs/include/simgear/misc/props.hxx, line 837: error(1377):
function SGPropertyNode::tie(const SGRawValueint , int) has
   already been declared
 bool tie (const SGRawValueint rawValue, bool useDefault = true);
  ^

/home/erik/fgfs/include/simgear/misc/props.hxx, line 988: error(1377):

  ^

../../src/Main/fg_props.hxx, line 468: error(1220): function fgTie has
   already been defined
   fgTie (const string name, int *pointer, bool useDefault = true)


Does anybody have any idea why this happens?

Erik
