[SOLVED] Help migrating to CEGUI 0.7 using Ogre 1.6.4

[Van]

MSVS 9.0
Ogre: 1.6.4 SVN (using boost 1.40)
CEGUI: 0.7 SVN

We are migrating from CEGUI 0.6.x to 0.7.0 (SVN) and we are getting a runtime exception when initializing the CEGUI system.
Based on the Ogre sample provide, I think we are doing it correctly. The error appears to happen inside CEGUI. The CEGUI log is not even created.

Code: Select all

   // Initialize the CEGUI system
   mGlobalResource->CEGUIRenderer = &CEGUI::OgreRenderer::create();
   CEGUI::ImageCodec *mImageCode = (CEGUI::ImageCodec *) &mGlobalResource->CEGUIRenderer->createOgreImageCodec();
   CEGUI::ResourceProvider *mResourceProvider = (CEGUI::ResourceProvider *) &mGlobalResource->CEGUIRenderer->createOgreResourceProvider();

   mCEGUISystem = &CEGUI::System::create( *mGlobalResource->CEGUIRenderer, mResourceProvider, 0, mImageCode );

   CEGUI::Logger::getSingleton().setLoggingLevel( (CEGUI::LoggingLevel) clsConfig::getSingleton().System.GUILogLevel );


We are getting the exception at this line:

Code: Select all

   mCEGUISystem = &CEGUI::System::create( *mGlobalResource->CEGUIRenderer, mResourceProvider, 0, mImageCode );


The exception

Code: Select all

Unhandled exception at 0x76dcfbae in Client.exe: Microsoft C++ exception: CEGUI::GenericException at memory location 0x0012d67c..


Ogre is already initialized and running. Are we initializing the CEGUI system properly?

Hi,

While looking at the sample code myself, i notice a difference with how Ogre is initialized. For example in this file:
http://crayzedsgui.svn.sourceforge.net/ ... iew=markup

You will notice this line:

Code: Select all

// initialise GUI system using the new automagic function
d_renderer = &CEGUI::OgreRenderer::bootstrapSystem();


That 'bootstrap' method already does a bit more on its own. However it doesn't seem to do much more that your custom code though. But it might be worth giving a try... note that you should comment your code which creates the imagecodec, resourceprovider and gui system!

HTH.

OK, after doing some debug, it seems to be failing in System::setXMLParser() at line 1579

Code: Select all

    d_xmlParser = createFunc();


This is happening in the CEGUI demo and the Ogre Demo_GUI (converted to 0.7). It still occurs if I use the bootstrap() function call you provided (thank you by the way!).

It would seem the XML parser specification is missing or needs to be provided. Is this missing in the demo's?
BTW, I am trying to link using the DEBUG and RELEASE configurations.

*sigh* Found it. I didn't include the EXPAT XML parser in the batch build. The DLL was missing. How embarrassing.

Interesting how CEGUI doesn't throw an excepting when the XML DLL is missing.

Hi,

Okay glad you got it to work. I am not sure why it doesn't throw. I should look at the code to know what's going on. IIRC it does check whether it can load the DLL and query some important function pointers from it...
