precompiled header madness

[pepin180]

I'm working in a simple 2d game engine, which is mean to be compiled as a dll

the problem is that Visual Studio asks me to add #include "StdAfx.h" in one of the headers that will be shared with the host process, and it's pretty weird, because I exported in the same way another part of the engine without any problem.

here is the code

//IRenderWindow.h

#pragma once
#include "export.h"


class IRenderWindow
{
public:
	
	virtual void Resize(int w, int h) = 0;
	virtual void Move(int x, int y) = 0;

	virtual void SetTitle(wchar_t *title) = 0;
	

	//virtual HDC GetDC() = 0;
	//virtual HWND GetHnd() = 0;

};


IRenderWindow PLASTIK2D_API *CreateRenderWindow(wchar_t *classname, wchar_t *title, int width, int height, void * icon, void * cursor, bool resizeable, bool maxButton);
IRenderWindow PLASTIK2D_API *CreateRenderWindow( wchar_t *title, int width, int height, bool resizeable, bool maxButton);

and the visual studio error

[QUOTE]1>c:\documents and settings\equipo\mis documentos\visual studio 2010\projects\48+\plastik2d\irenderwindow.h(23): fatal error C1010: unexpected end of file while looking for precompiled header. Did you forget to add '#include "StdAfx.h"' to your source?[/QUOTE]

while this one works fine

//IProfiler.h

#pragma once
#include "export.h"

class IProfiler
{
public:

	virtual void ReportMemory() =0;
	virtual void ReportThreads() =0;
};

IProfiler PLASTIK2D_API *getProfiler();

thanks in advice

Just don't use precompiled headers?

[QUOTE=neos300;36710537]Just don't use precompiled headers?[/QUOTE]

for and against about precompiled headers?
(ok, against this issue, but remove precompiled headers would be the easy sollution, i want at least know why or why not use them and why is this failing!!! )

You will almost certainely never use the features of them, and it's limited to windows only.

Precompiled headers cause all sorts of problems (like this one) that have cryptic/difficult solutions, best not to use them IMO.

Not true, GCC supports them as well. I do agree that you shouldn't use them unless you have a very good reason (i.e. large template libraries).
