Base class undefined? HELP!

Ledneh · 2002-10-07T15:52:20

Okay, building a D3D App. I have two objects: CObject and CBlock (declared/defined in Object.h/cpp and Block.h/cpp, respectively). CBlock, in theory, is supposed to inherit from CObject (which, by the way, has one of those "undefined" functions, I forget what they''re called... Code''s posted below, let me know if you know). However, the code below gives a "''CObject'': Base class undefined" error. Help: Object.h #pragma once #include "Direct3D.h" #include <time.h> class CObject { public: virtual void Update(); virtual void Render()=0; CObject(); ~CObject(); // ...and so forth... // }; Block.h #pragma once #include "Direct3D.h" #include "Object.h" class CBlock : public CObject { public: CBlock(); ~CBlock(); void Render(); private: int m_blockX; // in relation to playing field int m_blockY; D3DCOLOR m_color; // make this completely random? }; That''s it. If anyone can help, I''d appreciate it.

make sure "direct3d.h" doesnt include block.h nor object.h. Move your #include "direct3d.h" into object.cpp anyway if you dont need it in the header.

edit - i should probably refresh the page if i leave it on overnight

Damn me and my cleverly hidden circular dependencies. Damn me.

Thanks folks, I don''t know what I''d do without you. You were right; because of the way my #includes were organized, I ended up having block.h re-include itself before it included it''s own base. Fixed.
