Re: [osg-users] Crashing when calling "viewer->done()"

2011-05-20 Thread Robert Kern 
Hi,

Don, I tried your suggestion and then I started getting compile errors in 
osgViewer/ViewerBase

Skylark, I'm working on checking the dependencies. This application was 
originally linked to a server program that performed some other tasks for the 
visualization, however that is no longer needed. I'm trying to make this a 
stand alone application. I tried to copy the settings a dependencies from the 
original application but maybe I missed something.

Thank you!

Cheers,
Robert

Re: [osg-users] Crashing when calling "viewer->done()"

Hello Robert,

I may be a couple of days late, but I have a suggestion to solve your
crashing problem.  Instead of s dynamically allocated viewer use a
static object.


osgViewer::Viewer viewer;
...
 //don't want this: viewer = new osgViewer::Viewer();
...
 viewer.realize();

 int iter = 0;

while( !viewer.done() )
{
cout<<"iter: "

Re: [osg-users] Crashing when calling "viewer->done()"

Hello Robert,


Here is a simplified version of the code with all of the motion tracking and camera movement 
taken out. As the code is right now, my program crashes when calling viewer>done() the 
first time. If I comment out viewer->realize(), the program crashes on the first call to 
viewer->frame(). If I comment out viewer->realize() and viewer->frame() the the 
program runs indefinitely.


First of all, your example calls no OpenGL / GLU / GLUT code itself, so 
you can remove those headers...


Second of all, there was still an initTracker() call at the beginning of 
main() I had to comment out.


But after that, even though I don't have your data so it starts up an 
empty viewer, your code works for me. It doesn't crash.


...
iter: 594
iter: 595
iter: 596
iter: 597
iter: 598

So if it crashes for you, I suspect you have some mixup of release and 
debug libraries, or you have a mixup of versions of OpenSceneGraph, or 
something like that. Double- and triple-check your linker settings and 
dependencies, there is probably something there.


Hope this helps,

J-S

The functions are there, I just didn't post them because they a bit lengthy and 
I thought it would be a little superflous. Though I guess I could have noted 
that I left them out. I know the problem isn't with the camUpdate() function 
because through a little debugging, I realized that the program was crashing 
before it ever reached that function call. I'll keep working on it.

Thank you!

Cheers,
Robert

Re: [osg-users] Crashing when calling "viewer->done()"

2011-05-11 Thread Jean-Sébastien Guay 

Hello Robert,


I'm having a problem with my application crashing when I try to create a 
while(!viewer->done()) loop. The run time error I am getting is:

Unhandled exception at 0x00361710 in elevator.exe: 0xC005: Access violation 
reading location 0x0415.


You should run your program in a debugger and see where it crashes. This 
kind of message is totally useless, and just running in a debugger will 
likely point out exactly where the problem occurs, and since you have 
the code in front of you, you'll be able to fix it.



Could someone take a look and help me out?


In the posted code, several functions are not declared or defined 
(initTracker(), camUpdate(viewer) ) and I don't even see where the 
viewer variable is declared. You don't seem to be including any of your 
own headers so I don't see where those come from. We can have a quick 
look at some code but that's generally not very useful as it will leave 
us with more questions than answers. Post the complete code to a small 
example that reproduces your issue for best results.


In your particular case I'd be suspicious of the camUpdate(viewer) 
function, since it's being passed a pointer to the viewer, we can't know 
what's going on in there but something bad seems to be happening to the 
viewer.


Then again, you might also be mixing release and debug binaries when 
compiling, we have no way of knowing that either. A lot has been said 
about the need to be sure you link release with release, debug with 
debug when using Visual C++. Have a search in the archives or the forum 
for more details.


Hope this helps,

  Without even reading the code, this usually indicates trying to read a NULL 
pointer as a
pointer to an object.

  Check all your pointers in the debugger at the point you've crashed at.
