Re: [osg-users] [3rdparty] osgearth crashes when I load a shape file

[Jordan Sotomayer]

Thought I would give this thread a little bump to indicate that I am positive 
this is an error in Windows and not with OSG. TinyXML is not a bad idea. It is 
also not a bad idea to run some disaster recovery and move unnecessary files to 
a cloud to improve your performance. It can be as simple as that.

Re: [osg-users] [3rdparty] osgearth crashes when I load a shape file

[Glenn Waldron]

That's probably a generic Windows error, and not something I could fix. In
any case the plan is to get rid of the expat dependency anyway and embed
something like tinyxml instead, making the problem moot.

Hi glenn,

Also while playing with osgEarth, I got an error saying couldn't find ordinal 
63 in libexpat.dll.  Took me forever to find out what that meant, but it 
actually means that it couldn't find the dll file, whereas I thought it found 
the dll but something else was corrupt.  Not sure if you could make that error 
more discriptive but it could save a good couple hours or so trying to 
troubleshoot!  :P 


Thank you!

Cheers,
Nick

Thanks Martin; I've opened a ticket to install better error checking in this
scenario. http://www.osgearth.org/ticket/100

Re: [osg-users] [3rdparty] osgearth crashes when I load a shape file

[Martin Scheffler]

OK, got it working now. The problem was I did not set the working directory to 
osgEarth/bin. This caused the relative paths in the .earth file to be incorrect.
createFeatureProfile() in FeatureSourceOGR returned NULL because the file could 
not be loaded. This was not checked in 
FeatureModelSource::gridAndRenderFeaturesForStyle line 195:
[code]
FeatureGridder gridder( extent.bounds(), _gridding.get() );
[/code]
Causing the crash.

Feature overlay works perfect now!

Re: [osg-users] [3rdparty] osgearth crashes when I load a shape file

[Martin Scheffler]

It seems that OGR is unable to find the ESRI driver.
[code]
OGRGetDriverByName( "ESRI  Shapefile");
[/code]
returns NULL. This is not checked and causes a crash.

I am using FWTools 2.4.6. I have copied the DLLS in the FWTools bin directory 
to a location in my path. Do you have an idea what I do wrong?

Thank you!

Cheers,
Martin[/code]

Re: [osg-users] [3rdparty] osgearth crashes when I load a shape file

[Glenn Waldron]

Martin,
This is working correctly on my end. Are you using osgEarth 1.3? Can you
confirm that you have a usa.prj file alongside your usa.shp?

Re: [osg-users] [3rdparty] osgearth crashes when I load a shape file

[Martin Scheffler]

It's the data included in the SVN, and the example that I linked in the first 
post.


Thank you!

Cheers,
Martin

Hi Martin,

Can you provide your data and a sample .earth file that is causing the issue?

Thanks!
