No such file or directory- Simple Link Error Help?

Here are the first few lines of my *.h file:

Code:

---

#ifndef PHYSICSLIB_H
#define PHYSICSLIB_H
 
#pragma once
 
#include "Core/element.h"
#include "Core/parameters.h"
#include "Core/smartPointer.h"
 
#include "Relationships/relationships.h"
#include "Relationships/oneWay.h"
#include "Relationships/twoWay.h"
#include "Relationships/hit.h"
 
#include "Callbacks/elementDrawer.h"
#include "Callbacks/elementUpdater.h"

---

After trying to build, the compile output reads:

In the *.pro file I have:
QT += opengl
SOURCES += main.cpp \
mainwindow.cpp \
glwidget.cpp \
Core/smartPointer.cpp \
Core/physicsLib.cpp \
Core/physics.cpp \
Core/element.cpp \
Core/boundingBox.cpp
HEADERS += glwidget.h \
mainwindow.h \
Core/utilities.h \
Core/smartPointer.h \
Core/physicsLib.h \
Core/parameters.h \
Core/element.h \
Core/boundingBox.h \
Callbacks/elementUpdater.h \
Callbacks/elementDrawer.h \
Relationships/types.h \
Relationships/twoWay.h \
Relationships/relationships.h \
Relationships/oneWay.h \
Relationships/hit.h

I'm not sure why these files aren't being recognized: I know it's probably just a simple linking error... any advice would be appriciated. Thank you.

in Core/physicsLib.h you have to write

Code:

---

#include "element.h"

---

not

Code:

---

#include "Core/element.h"

---

etc.

I tried that and the same errors occured.

Any other suggestions?

try to use an explicit INCLUDEPATH in your pro file.

I added

Code:

---

INCLUDEPATH += -I"x:\Cerulean_\Core\element.h"

---

and so on... to the .pro file but still get the same error:

Core/element.h: No such file or directory

I haven't done any explicit INCLUDEPATH before so I'm not sure if I got it right yet and couldn't tell from the online help stating:

-I <string> ........ Add an explicit include path.

Thanks for your help.
