The weird thing about this problem is that other .cpp and .h files can find the file but not this one, they're all in the SAME folder. My file structure is as follows:

/Entity.h // is being included

/Graphics.cpp // can include

/Graphics.h // CANNOT include

/main.cpp // can include

/Physics.cpp // can include

/Physics.h // can include

Graphics.cpp, main.cpp, Physics.cpp, Physics.h are all able to include Entity.h but Graphics.h cannot.

This is Entity.h

#ifndef ENTITY_H
#define ENTITY_H

#include <vector>
#include <SFML/Graphics.hpp>

using namespace std;

struct entity

 int ID;
 vector<long double> position;
 vector<long double> velocity;
 vector<long double> acceleration;
 sf::Color colour;
 sf::CircleShape selfImage;
 long double mass;
;

entity createEntity(long double x, long double y, long double xV, long double yV, long double m, int newID)

 entity e;
 // assign entity ID and increment entity ID count
 e.ID = newID;

 // initialise velocity, acceleration & position to 0
 e.position.resize(2, 0);
 e.velocity.resize(2, 0);
 e.acceleration.resize(2, 0);

 e.position = x, y;
 e.velocity = xV, yV;

 // setup self-image
 e.colour = sf::Color (255, 0, 0);
 e.selfImage.setFillColor(e.colour);

 // initialise mass
 e.mass = m;

 return e;
;


#endif // ENTITY_H

This is Graphics.h

#ifndef GRAPHICS_H_
#define GRAPHICS_H_

#include <SFML/Graphics.hpp>
#include <vector>

class Graphics

 public:
 Graphics(int WIDTH, int HEIGHT);
 ~Graphics();
 void update(vector<entity> entities);

 int W_WIDTH;
 int W_HEIGHT;
 sf::RenderWindow window;

;



#endif /* GRAPHICS_H_ */

Physics.h, an example of something which can include Entity.h

#ifndef PHYSICS_H
#define PHYSICS_H

#include <Entity.h>
#include <vector>
using namespace std;


class Physics

 long double G_CONST = 0.00000000006674;
 public:
 Physics();
 virtual ~Physics();

 const int MAP_WIDTH = 1000;
 const int MAP_HEIGHT = 1000;

 vector<vector<entity*>> gameMap;
 vector<entity> entityList;

 void addEntity(entity e);
 int update();

 protected:

 private:
;

#endif // PHYSICS_H

The console output is the following

I am using Eclipse on Debian. This has me puzzled, I cannot see a difference in the files.

EDIT:
using "" instead of <> around the include statements file name fixed the problem. Other problems have ensued however :((((((
