Right, I've decided I really, really, REALLY hate the C++ preprocessor, and might just go and write my next code in D, but that's not the problem.
I'm using a couple of renderer classes called I_Renderer and OGLRenderer, which derives from I_Renderer.
They are in the mglGraphics.h file, which is included in one slightly monolithic header, called locus_main.h (I'll show it in a minute) which each header and each source file includes, like so;
#ifndef LOCUS_MAIN_H
#define LOCUS_MAIN_H
#include <windows.h>
#include <cmath>
...
// misc
#include <error.h>
#include <mglFile.h>
#include <mglSingleton.h>
#include <mglTime.h>
#include <mglResourceManager.h>
// OS dependant
#include "mglWindow.h"
#include "mglInput.h"
// math
#include "locus_math.h"
#include "frustum.h"
// graphics
#include <gl/gl.h>
#include "texture.h"
#include "mglGraphics.h"
#include "level.h"
// graphics constants
/*const Engine::RGBA_COL RGB_BLACK(0.0f);
const Engine::RGBA_COL RGB_WHITE(1.0f);*/
//physics
#include "physics.h"
// sound
#include "sound.h"
// scene
#include "scene_entity.h"
#include "scene_graph.h"
#include "scene.h"
// the application class to wrap all of the above
#include "locus_application.h"
#endif // LOCUS_MAIN_H
and the mglGraphics.h
#ifndef H_GRAPHICS
#define H_GRAPHICS
#include "locus_main.h"
#include <windows.h>
#include <gl/gl.h>
#include <cmath>
namespace Engine
{
class I_Renderer
{
...
};
class OGLRenderer:public I_Renderer
{
...
};
}
Now, when I try;
#ifndef APPLICATION_H
#define APPLICATION_H
#include "locus_main.h"
class App
{
Engine::Window m_wnd;
Engine::mglInput* m_input;
Engine::mglTime m_timer;
Engine::OGLRenderer* render;
public:
virtual void Init();
virtual void Go();
virtual ~App(){}
};
#endif // APPLICATION_H
and compile, I'm told
locus_application.h:11: error: using-declaration for non-member at class scope
locus_application.h:11: error: expected `;' before '*' token
:: === Build finished: 2 errors, 0 warnings ===
Does anyone have any ideas, as I'm completely stumped
