cannot allocate an object of type

[full_newbie]

I am use http://irrlicht.sourceforge.net/phpBB2/ ... sc&start=0
Please help! I am getting errors:

Code: Select all

CGUISlotWindow.cpp:233: error: cannot allocate an object of type `irr::gui::CGUIBringUpSlotWindowButton'
CGUISlotWindow.cpp:233: error:   because the following virtual functions are abstract:
IGUIButton.h:128: error:  virtual void irr::gui::IGUIButton::setScaleImage(bool)
IGUIButton.h:131: error:  virtual bool irr::gui::IGUIButton::isScalingImage() const

What happens?

I don't know that class, but that error means that you derived from a class with pure virtual functions and did not add an implementation for those functions. Just add any implementation for setScaleImage and isScalingImage (they can be empty or just return true or false in the latter case) and it should compile.
