Hello all,
I'm trying to migrate my application from GCC to Visual C++ 2005. (...)
The application is QT-based, and use OpenSceneGraph as 3D engine.
It compiles fine, but crashes at launch. I've reproduced it on a small exe
using one of OSG's example. Here is the code:
Code:
#include <osgViewer/Viewer>
#include <osgGA/TrackballManipulator>
#include <osgDB/ReadFile>
#include <QtCore/QTimer>
#include <QtGui/QKeyEvent>
#include <QtGui/QApplication>
#include <QtOpenGL/QGLWidget>
using Qt::WFlags;
#include <iostream>
class AdapterWidget : public QGLWidget
{
public:
AdapterWidget( QWidget * parent = 0, const char * name = 0, const QGLWidget *
shareWidget = 0, WFlags f = 0 );
virtual ~AdapterWidget() {}
osgViewer::GraphicsWindow* getGraphicsWindow() { return _gw; }
const osgViewer::GraphicsWindow* getGraphicsWindow() const { return _gw; }
protected:
void init();
QTimer _timer;
osgViewer::GraphicsWindowEmbedded* _gw;
};
AdapterWidget::AdapterWidget( QWidget * parent, const char * name, const
QGLWidget * shareWidget, WFlags f):
QGLWidget(parent, shareWidget, f)
{
connect(&_timer, SIGNAL(timeout()), this, SLOT(updateGL()));
_timer.start(10);
_gw = new osgViewer::GraphicsWindowEmbedded(0,0,800,600);
}
class ViewerQT : public AdapterWidget, public osgViewer::Viewer
{
public:
ViewerQT(QWidget * parent = 0, const char * name = 0, const QGLWidget *
shareWidget = 0, WFlags f = 0):
AdapterWidget( parent, name, shareWidget, f )
{
getCamera()->setViewport(new osg::Viewport(0,0,width(),height()));
getCamera()->setGraphicsContext(getGraphicsWindow());
setThreadingModel(osgViewer::Viewer::SingleThreaded);
}
virtual void initializeGL()
{
QGLWidget::initializeGL();
}
virtual void paintGL()
{
frame();
}
};
int main( int argc, char **argv )
{
QApplication a( argc, argv );
ViewerQT* viewerWindow = new ViewerQT();
viewerWindow->show();
a.connect( &a, SIGNAL(lastWindowClosed()), &a, SLOT(quit()) );
return a.exec();
}
This is the compilation result. I use the pre-compiled libraries but it's the
same when I recompile it myself. I statically link against Qt and OSG;
everything is in release mode.
I got weird Qt warnings (QtOpenGL.lib(qpaintengineex_opengl2.obj) : warning
LNK4217... ??) , but I have no idea if it's related.
And - finally -, this is the backtrace at execution:

I tried to active OSG debug, but with no result:

Does anyone have a clue of what the problem might be?
Thank you!
