    QVector declaration does not see type as a correct type

    Hi,
    First of all I'd like to say Hello Forum! as I'm a new guy in town

    Now, there is an amazing Open Dynamics Engine library (Open Dynamics Engine - home) that I just wanted to mess around but when compiling one of its tutorial sources I get the error which I cannot overcome: Index of /Membres/Xavier.Decoret/resources/ode/tutorial1/D

    While compiling (Ubuntu 9.04) I get the following error:
    viewer.h:26: error: ISO C++ forbids declaration of 'QVector' with no type.

    Sure, but the type is provided:
    7: class Object; //class declaration
    26: QVector <Object*> _objects;

    I prepared an example with std::vector aside and it can be created with Object*, QVector does not differ in this matter.

    The object.h/cpp is correctly compiled.

    What is wrong in this example?

    Best Regards,
    Tomek

    Where is the type for QVector? The compiler hasn't seen any declaration/definition for QVector, hence the error.

    Outside of your DOS world, your header file is meaningless.

    Uhh, I don't think it's the lack of QVector declaration. The QVector declration comes down from
    <code>#include <QGLViewer/qglviewer.h></code>

    That's what it says. QVector has no type.

    Just #include <QVector>

    Thank you! It was indeed lack of QVector declaration, I should not argue with wiser people :-)

    The QVector itself was in Qt2.x, then in Qt3 it was obsolete and in Qt4 again implemented, this made me confused, obviously the tutorial was for Qt2.x while I'm using Qt3.x

    Thank you once again!
