Crash at the scheme loading

[Elrick]

I use CeGUI 0.2 and Ogre 1.0 RC1 with the OgreRenderer which is located on the Ogre CVS (in my opinion it's will better if you include it in the zip/tar.bz2).

When I try to load a scheme via :

SchemeManager::getSingleton().loadScheme((utf8*)"my scheme.xml");

It makes my program crash at the end of :

OgreCEGUIResourceProvider::loadRawDataContainer

Maybe I don't use the good renderer and the one I use is still under developement ?

[spannerman]

Elrick, was your "my scheme.xml" scheme working before you updated to these versions of CEGUI and OGRE? What do the error logs say?

[Elrick]

Yes, with CeGUI 0.1 and Ogre 0.15, it was working.

I've tried to simplify the scheme at the maximum:

<?xml version="1.0" ?>
<GUIScheme Name="Milcis">
</GUIScheme>

and the same problem occurs.

I think I have identified the problem.

I was in Debug mode and I use the Ogre Release. Before, I have used the Ogre lib in release mode in a debug program ...

It seems I can't do this anymore

[Elrick]

I think I've wrote this a bit too fast.

So, in releas emode, there isn't any problems but in debug mode there is the problem I've wrote in the first message ...

[CrazyEddie]

What is the exact exception that you're getting? Also compiler version & STL type in use.

Exceptions like this are usually related to memory problems, make sure you app is dynamically linking to the correct runtime (Debug Multithreaded DLL). If you use STLport ensure that _STLP_DEBUG is defined for your projects Debug configuration.

I use Visual Studio .Net 2003 (7.1) and the default STL library of VS.
I have recompiled the Ogre library + CeGUI + OgreGuiRenderer and now I have an assertion on deleting a block at the end of Rawcontainer (or something like that, I don't have my code at the place where I write this message)

Yeah I know, I know
It's a memory crash/problem/something else
But I'm in DLL Debug Multithread and I don't use STLport

[CrazyEddie]

This is the same general config that I use on Win32. There was a major issue with this a while back which has been fixed. I am currently unable to reproduce this

I have the same problem with Ogre 1.0 (from Ogre's v1-0 CVS branch) and CEGUI 0.2 (currently in debug mode). After reading the configuration file the block end causes the RawDataContainer to be deleted and this ends up in a memory error

Do you have any idea about how to fix it?

[CrazyEddie]

It seems that everyone is getting this now (except me), I'll see if I can find the time to attempt to reproduce the problem. Until I can reproduce this, I have no idea how to fix it (if it is not one of the affore mentioned issues)

CE, you are not alone. I built the Ogre VC7.1 SDK using Ogre CVS v1-0-0 and CEGUI 0.2.0 src and found no problems running Demo_GUI in debug. I didn't use the pre-built Xerces so maybe that has something to do with it. Had me worried when I saw this post just after the SDK were released so I downloaded the SDK that I had uploaded and the gui demo runs fine in debug and release.

[CrazyEddie]

Thanks for the info.

I'm going to try and track this one down today, if at all possible.

CE.

[Assidragon]

Just a note, I'm using OGRE 1.0 (SDK), the CEGUI stable release and the Xerces DLL I downloaded from this site, and have no problems with CEGUI. =)

[CrazyEddie]

I'm glad there's still a few of us who are able to use the system

I spent quite a while yesterday playing around with various things trying to recreate this issue, but in the end could not reproduce it (except to change project settings which I already know to cause it). I did not switch around the dependedncy DLLs though, it does seem that there may be an issue with using dependency files other than the ones either supplied here or built yourself.

In case anyone's searched and found this topic, the advice now (in addition to things previously mentioned) is to try the CEGUI dependency files from this site in place of the ones from the Ogre dependency packages.

CE.

[walaber]

just a note, I was recently using the version of CEGUI that comes as part of the dependencies to Ogre 1.0 for my project, and was experiencing the same problem (except in release mode).

I compiled CEGUI 0.2.0, and linked my project to it instead, and then copied over all of the dependency library .dll files from the CEGUI dependencies into my Ogre project directory, and the problem has since gone away!

I think it must be an issue with one of the pre-compiled .dll dependency files (DevIL, ILU, ILUT) between the ones that come with Ogre 1.0 and CEGUI.

p.s. other than this slight issue, my project with CEGUI is going great!
