System ctor throws exception

[Tobse]

I tried to use cegui 0.5.0b with ogre 1.4.0. The following code throws an exception in the CEGUI::System ctor:

Code: Select all

// Set up GUI system
_guiRenderer = new CEGUI::OgreCEGUIRenderer(_window, Ogre::RENDER_QUEUE_OVERLAY, false, 3000, _sceneMgr);
_guiSystem = new CEGUI::System(_guiRenderer);


The exception message is:

Code: Select all

WindowFactoryManager::getFactory - A WindowFactory object, an alias, or mapping for 'Falagard/Button' Window objects is not registered with the system.


I don't know what to do.

Any hints?

System: gentoo amd64

Do you have the newest datafiles ? Are you sure that they are used ?

[Tobse]

Yes, I think so. Would the CEGUI.log help?

[Pompei2]

If there are some errors in it, definitely
if there are some warnings, maybe. else I don't think so.
What scheme/skin are you using ?

edit:
seems to be the same problem

Here are lines from the log:

I cannot see a problem here!?!

[Pompei2]

I see one ! In fact, I see two the two error messages. They also throw exceptions, if you don't catch them your application seems to "crash".

[Tobse]

Ok, the error messages are there, but my question is, why the exception is thrown? I catch it, so the application runs, but without gui.

Because the exception is thrown in the constructor of System, the error cannot be in the source code. So there must be an error in the configuration files. How can I figure out, where the error could be?

[Pompei2]

Your datafiles seem to be wrong, indeed. Reload the files from internet, especially the .scheme and .looknfeel files seem to make problems.
