Debug Error , QT 6_2_1 MSVC20119 when i try to use OGR 3D in Qt

[Alex42]

Hello everybody
I was able to configure, compile and install ogre3D, and when i try to test a simple project i have the MSVC compiler error .

I made a simple class , where I more or less copy a basic tutorial code:
here's the .h header

#ifndef QOGREBASICTEST_H
#define QOGREBASICTEST_H
#include <QDebug>
#include "Ogre.h"
#include "OgreApplicationContextQt.h"
#include "OgreInput.h"
#include "OgreRTShaderSystem.h"
#include <iostream>

using namespace Ogre;
using namespace OgreBites;

class QOgreBasicTest : public ApplicationContextQt
        , public InputListener
{
public:
    QOgreBasicTest();
    virtual ~QOgreBasicTest() {}

void setup();
bool keyPressed(const KeyboardEvent& evt);
};


#endif // QOGREBASICTEST_H

and the .cpp

#include "QOgreBasicTest.h"

QOgreBasicTest::QOgreBasicTest()
 : ApplicationContextQt("QtOgreTest1")
{
 qInfo()<<"1";
}

void QOgreBasicTest::setup()
{
    // do not forget to call the base first
        qInfo()<<"2";
        ApplicationContextQt::setup();
        qInfo()<<"3";
        addInputListener(this);

    // get a pointer to the already created root
    Root* root = getRoot();
    SceneManager* scnMgr = root->createSceneManager();

    // register our scene with the RTSS
    RTShader::ShaderGenerator* shadergen = RTShader::ShaderGenerator::getSingletonPtr();
    shadergen->addSceneManager(scnMgr);

    // -- tutorial section start --
    //! [turnlights]
    scnMgr->setAmbientLight(ColourValue(0.5, 0.5, 0.5));
    //! [turnlights]

    //! [newlight]
    Light* light = scnMgr->createLight("MainLight");
    SceneNode* lightNode = scnMgr->getRootSceneNode()->createChildSceneNode();
    lightNode->attachObject(light);
    //! [newlight]

    //! [lightpos]
    lightNode->setPosition(20, 80, 50);
    //! [lightpos]

    //! [camera]
    SceneNode* camNode = scnMgr->getRootSceneNode()->createChildSceneNode();

    // create the camera
    Camera* cam = scnMgr->createCamera("myCam");
    cam->setNearClipDistance(5); // specific to this sample
    cam->setAutoAspectRatio(true);
    camNode->attachObject(cam);
    camNode->setPosition(0, 0, 140);

    // and tell it to render into the main window
    getRenderWindow()->addViewport(cam);
    //! [camera]

    //! [entity1]
    Entity* ogreEntity = scnMgr->createEntity("ogrehead.mesh");
    //! [entity1]

    //! [entity1node]
    SceneNode* ogreNode = scnMgr->getRootSceneNode()->createChildSceneNode();
    //! [entity1node]

    //! [entity1nodeattach]
    ogreNode->attachObject(ogreEntity);
    //! [entity1nodeattach]

    //! [cameramove]
    camNode->setPosition(0, 47, 222);
    //! [cameramove]

    //! [entity2]
    Entity* ogreEntity2 = scnMgr->createEntity("ogrehead.mesh");
    SceneNode* ogreNode2 = scnMgr->getRootSceneNode()->createChildSceneNode(Vector3(84, 48, 0));
    ogreNode2->attachObject(ogreEntity2);
    //! [entity2]

    //! [entity3]
    Entity* ogreEntity3 = scnMgr->createEntity("ogrehead.mesh");
    SceneNode* ogreNode3 = scnMgr->getRootSceneNode()->createChildSceneNode();
    ogreNode3->setPosition(0, 104, 0);
    ogreNode3->setScale(2, 1.2, 1);
    ogreNode3->attachObject(ogreEntity3);
    //! [entity3]

    //! [entity4]
    Entity* ogreEntity4 = scnMgr->createEntity("ogrehead.mesh");
    SceneNode* ogreNode4 = scnMgr->getRootSceneNode()->createChildSceneNode();
    ogreNode4->setPosition(-84, 48, 0);
    ogreNode4->roll(Degree(-90));
    ogreNode4->attachObject(ogreEntity4);
    //! [entity4]

    // -- tutorial section end --

}

bool QOgreBasicTest::keyPressed(const KeyboardEvent &evt)
{
    if (evt.keysym.sym == SDLK_ESCAPE)
    {
        getRoot()->queueEndRendering();
    }
    return true;
}

Well, if I stop here, it compiles with no error.

So in my mainwindow, I just put a push button to create an instance of this class

here's the code of the button

void MainWindow::on_pushButton_clicked()
{
 //QOgreBasicTest *testOgre = new QOgreBasicTest();
 //testOgre->setup();
}

If I let those 2 lines commented, the code compile, the app start
if I uncomment those lines (even the first one)... the code compile and the app crash immediatly with Debug Error , QT 6_2_1 MSVC20119

Note that I tried to compile some projects with VS2019 and it runs

feedback, advice you are welcome
thak you in dvance

As always when a program is crashing - run in debugger, see where it crashes.

hi , and thank you for your answer,
i run in debugger , and crashed here
when i create an instance of this class

 QOgreBasicTest *testOgre = new QOgreBasicTest();

[Alex42]

i have exactly the same problem when i try to use a console aplic

I have exactly the same problem when I try to use a console application, with another code approach ,
here's my .main file

class Application
{
public :
    Application();
    ~Application();

    void Start();
    void Run();
    void Exit();

public :
    Ogre::Root* pRoot;
    Ogre::SceneManager* pSceneManager;
    Ogre::RenderWindow* pRenderWindow;
    Ogre::Viewport* pViewport;
    Ogre::Camera* pCamera;
};

Application::Application()
{
    pRoot = 0;
    pSceneManager = 0;
    pRenderWindow = 0;
    pViewport = 0;
    pCamera = 0;
}

Application::~Application()
{
    Exit();
}

void Application::Run()
{
    pRoot->startRendering();
}

void Application::Start()
{
      qInfo() << "tested";
    pRoot = new Ogre::Root();
  qInfo() << "tested";
    pRenderWindow = pRoot->initialise(true,"Ma premiere application Ogre");

    pSceneManager = pRoot->createSceneManager("MonGestionnaireDeScene");

    pCamera = pSceneManager->createCamera("MaCamera");

    pViewport = pRenderWindow->addViewport(pCamera);

}

void Application::Exit()
{
    if (pRoot!=0) delete pRoot;
}
#if OGRE_PLATFORM == OGRE_PLATFORM_WIN32
#define WIN32_LEAN_AND_MEAN
#include "windows.h"

INT WINAPI WinMain( HINSTANCE hInst, HINSTANCE, LPSTR strCmdLine, INT )
#else
int main(int argc, char **argv)
#endif
{
    try {

     Application MonApplication ;
         MonApplication.Start ();
         MonApplication.Run() ;
     qInfo() << "tested";
         MonApplication.Exit();

    } catch( Ogre::Exception &e ) {
#if OGRE_PLATFORM == OGRE_PLATFORM_WIN32
        //MessageBox( NULL, e.what(), "An exception has occurred!", MB_OK | MB_ICONERROR | MB_TASKMODAL);
        qInfo() << "fucking";
#else
        fprintf(stderr, "An exception has occurred: %s\n",
                e.what());
#endif
    }

    return 0;
}

@Alex42 said in Debug Error , QT 6_2_1 MSVC20119 when i try to use OGR 3D in Qt:

i run in debugger , and crashed here

What I see in your screenshot is the debugger stopped at a breakpoint on the start of on_pushButton_clicked(), not "crashed" in the screenshot like you claim?

when i create an instance of this class

QOgreBasicTest *testOgre = new QOgreBasicTest();

If it crashes while executing that line then let it do so and show the stack trace after the crash has happened?

hi @JonB thank you for your answer
here the screenshot when i try to unfold the debug withe another exception

for more details

[Alex42]

(other program )when i run in only main cpp , i have the same problem

 Application MonApplication ;
         MonApplication.Start ();
         MonApplication.Run() ;

[jsulm]

@Alex42 It crashes inside Ogre::Root(), so step into it and see what happens.

@jsulm said in Debug Error , QT 6_2_1 MSVC20119 when i try to use OGR 3D in Qt:

step into it

i don' know why i can't setup into it , i obtain this error every time i try to setup into it

[Alex42]

i see many project use ogr in Qt , but under cMake not under qmake , for this i think the probleme is qmake

[Christian Ehrlicher]

You're mixing debug and release dlls which is not allowed under windows. Compile ogre in debug mode and use these libraries. You must not mix VCRUNTIMExxx.dll and VCRUNTIMExxxD.dll
