Hi,

I finally have resolved my problem with the QGLViewer Library.
The problem was from the support of QT3 and the definition of function 
in QGLViewer.

Here is the definition which has been caused my problem :

[code]#if QT_VERSION < 0x040000 || defined QT3_SUPPORT
  explicit QGLViewer(QWidget* parent=NULL, const char* name=0, const 
QGLWidget* shareWidget=0, Qt::WFlags flags=0)
      : QGLWidget(parent, name, shareWidget, flags)
  { defaultConstructor(); }

  explicit QGLViewer(const QGLFormat& format, QWidget* parent=0, const 
char* name=0, const QGLWidget* shareWidget=0,Qt::WFlags flags=0)
      : QGLWidget(format, parent, name, shareWidget, flags)
  { defaultConstructor(); }

  QGLViewer(QGLContext* context, QWidget* parent, const char* name=0, 
const QGLWidget* shareWidget=0, Qt::WFlags flags=0)
# if QT_VERSION >= 0x030200
      : QGLWidget(context, parent, name, shareWidget, flags) {
# else
      // MOC_SKIP_BEGIN
      : QGLWidget(parent, name, shareWidget, flags) {
          Q_UNUSED(context);
          // MOC_SKIP_END
# endif
          defaultConstructor(); }
#endif[/code]

So, I just commented the line which cause the unresolved symbol to avoid it.
Thank you very much for your previous answer  - specially the psapi.lib 
which still came from nowhere in my mind.
Thank you very much Laurent Saboret.

Best Regards.
