Crash Using Ogre GUI Renderer and CEGUI

[jchmack]

i am trying to rebuild my engine from the ground up. Before i had Cegui as part of my main game class, this time i am trying to separate it into its own GUI class. Before i had this code which worked fine:

Code: Select all

void game4::InitializeCEGUI()
{
	//create CEGUI
	mGUIRenderer = new CEGUI::OgreCEGUIRenderer(mWindow, Ogre::RENDER_QUEUE_OVERLAY, false, 3000, mSceneMgr);
	mGUISystem = new CEGUI::System(mGUIRenderer);
..........

now i try this very similar code in my new app i get a crash:

Code: Select all

//create CEGUI
	mGUIRenderer = new CEGUI::OgreCEGUIRenderer(mWindow, Ogre::RENDER_QUEUE_OVERLAY, false, 3000, mSceneMgr);
	//if(mGUIRenderer == NULL)
	mGUISystem = new CEGUI::System(mGUIRenderer);

and the crash:

Unhandled exception at 0x7c812a5b in game5.exe: Microsoft C++ exception: CEGUI::GenericException at memory location 0x0013ed28..





if i uncomment the if(mGUIRenderer == NULL) i don't get a crash but of course the system isn't created....... so for some reason "new CEGUI::OgreCEGUIRenderer(mWindow, Ogre::RENDER_QUEUE_OVERLAY, false, 3000, mSceneMgr);" Is returning NULL.

Any ideas?

edit:

im using: 17:34:01: *-*-* Version 1.4.0RC2 (Eihort)
I dont believe a version update will help because i was using the same version of ogre with my older engine and it worked fine.

my new class is very simple:

Code: Select all

#ifndef GUIManager_H
#define GUIManager_H

#include <CEGUI/CEGUIImageset.h>
#include <CEGUI/CEGUISystem.h>
#include <CEGUI/CEGUILogger.h>
#include <CEGUI/CEGUISchemeManager.h>
#include <CEGUI/CEGUIWindowManager.h>
#include <CEGUI/CEGUIWindow.h>
#include <CEGUI/CEGUIPropertyHelper.h>
#include <CEGUI/elements/CEGUICombobox.h>
#include <CEGUI/elements/CEGUIListbox.h>
#include <CEGUI/elements/CEGUIListboxTextItem.h>
#include <CEGUI/elements/CEGUIPushButton.h>
#include <CEGUI/elements/CEGUIScrollbar.h>
#include "OgreCEGUIRenderer.h"
#include "OgreCEGUIResourceProvider.h"

#include "Ogre.h"

class GUIManager
{
public:

	GUIManager();

	void CreateGUIManager(Ogre::RenderWindow* mWindow,Ogre::SceneManager* mSceneMgr,std::map<Ogre::String, Ogre::String> settings);

	CEGUI::OgreCEGUIRenderer*	mGUIRenderer;
	CEGUI::System*				mGUISystem;
	CEGUI::Window*				mEditorGuiSheet;
};

#endif

Code: Select all

#ifndef GUIManager_CPP
#define GUIManager_CPP

#include "GUIManager.h"

GUIManager::GUIManager()
{
	mGUIRenderer = NULL;
	mGUISystem = NULL;
}

void GUIManager::CreateGUIManager(Ogre::RenderWindow* mWindow, Ogre::SceneManager* mSceneMgr,std::map<Ogre::String, Ogre::String> settings)
{
	//create CEGUI
	mGUIRenderer = new CEGUI::OgreCEGUIRenderer(mWindow, Ogre::RENDER_QUEUE_OVERLAY, false, 3000, mSceneMgr);
	mGUISystem = new CEGUI::System(mGUIRenderer);
}

i dont really see a reason for this crash....... its an overly simple class could someone please try and app with this class and see if you can run CreateGUIManager without a crash?

thx in advance to anyone who helps =)[/code]

i believe this guy might be having a similar problem:

http://www.cegui.org.uk/phpBB2/viewtopi ... 2594#12594

I am PRETTY SURE that i am initializing mWindow and mSceneMGR fine:

Code: Select all

mWindow = mRoot->initialise(true, WindowName);
mSceneMgr = mRoot->createSceneManager(ST_GENERIC, "NxOgre");

if(mWindow ==	NULL)
	cout << "BAH WINDOW" << endl;
if(mSceneMgr==NULL)
	cout << "BAH Manager" << endl;

i use window and scene manager in many places in my app and it seems to work fine there.

ive had problems like that. make sure you have all dll's in the same folder. that was my problem =)

I will double check but i am almost certain i have all the correct dlls including the debug ones for debug mode. Usually when i am missing a DLL I get a crash asking for a Specific one though.

sigh i got it..... it was the DLL issue. Thank you tons murderv for the recommendation. I didn't know that if you were missing a DLL it wouldn't always ask for that DLL in specific. I don't know if this is an ogre problem or a CEGUI one but it would be nice if you got an assert saying that your missing the DLL. Well Thx to all who helped =)
