Visual Studio 2017 Intellisense error

[DEhqDjzh]

Severity	Code	Description	Project	File	Line	Suppression State
Error (active)	E2904	PCH warning: header stop not at file scope.  An IntelliSense PCH file was not generated.	FCEC	c:\Users\lenovo\Desktop\Code Stuff The IV\FCEC\FCEC\main.c	4	 

In my C projects, I get this error on the same line with #include "Engine.h"

How to fix this

[Ganado]

Can you show your Engine.h file?

PCH stands for pre-compiled header, by the way. Does your actual program still compile?

small projects, you can often quick fix this by delete the intelisense file and it will rebuild a working one.

Engine.h

 
#pragma once

#include <stdio.h>
#include <SDL.h>

#define bool	_Bool // stdbool.h
#define false	0
#define true	1
bool gameisrunning;
SDL_Event event;

void getinput();



struct Engine
{

	int test;
};

Did you forget to #include <stdafx.h> in main.c? If your project uses precompiled headers, this line must be the first non-comment line in every .c and .cpp file.

[DEhqDjzh]

there is no file called stdafx.h in my project or includes

[MikeyBoy]

bool gameisrunning;
SDL_Event event;

This may be unrelated to your problem, but: what are you doing to avoid multiple redefinition of global variables?

Found the Solution! Removing #pragma once solved the problem

[Ganado]

I'm not exactly sure why that fixes it, but please note that you should have proper header guards in C and C++. (Most if not all compilers support #pragma once, but it's technically non-standard).

This means something like:

#ifndef ENGINE_H_HEADER_GUARD
#define ENGINE_H_HEADER_GUARD

#include <other_stuff>

struct Whatever {  };

#endif // ENGINE_H_HEADER_GUARD 

where "ENGINE_H_HEADER_GUARD" needs to be a unique macro token.
