Linking SMFL Library to Qt on Windows machine

GroundZero

Dear reader,

For the last 21 hours I have been trying to find out how to use the SMF library.
I can include the header without any problems, my program does see the headers to but
when I try to test my scripts I get a lot of errors.

I have been told this is because I did not yet link any library to my project.

I went to my .PRO file, right clicked on it and indeed... a option to link a library but...

Three options... which one should I pick?
What files (or folders) should I copy to my project (SMFL folders to my project)
How do I add them, and which files do I need to add?

I hope someone can help me out on this matter.

Yours sincerely,

GZ

You need to provide some more information. For instance it would help if you are posting your .pro file and possibly addtional information of importance.

GroundZero

Well, it is a new project. I havent done anything yet.
I am just following the tutorials on SMFL boards.

My pro file at this point:

@#-------------------------------------------------

Project created by QtCreator 2011-08-21T19:06:23

#-------------------------------------------------

QT += core

QT -= gui

TARGET = game
CONFIG += console
CONFIG -= app_bundle

TEMPLATE = app

SOURCES += main.cpp
@

and my cpp file

@#include <SFML/Window.hpp>

int main()
{
// Create the main window
sf::Window App(sf::VideoMode(800, 600, 32), "GroundZero");

// Start main loop
bool Running = true;
while (Running)
{
    App.Display();
}

return EXIT_SUCCESS;

}

best regards,

You need to add a "libs parameter":http://doc.qt.nokia.com/4.7/qmake-variable-reference.html#libs to your .pro

octal

Indeed, you need to link against your sfml libraries by adding a LIBS statement, like :

@
LIBS *= -L"path/to/your/SFML/libraries" -lsfml-graphics -lsfml-window -lsfml-system -lsfml-main
@

This may not be the exact libraries, but you get the idea ;)

GroundZero

Yeah I see now thank you very much!!!

Only 1 small problem... SFML 2.0 does not include .lib files... is that correct? all I can find is .h (header) files :)

Thank you very much for your replies so far guys!

EDIT:

SFML\extlibs\libs-msvc\x86

has some lib files but when i add those and press "RUN" it still asks for more lol. Ill try figuring it out if I cant solve it ill 'edit' this post :D

koahnig

for including header files you can use "INCLUDEPATH ":http://doc.qt.nokia.com/4.7/qmake-variable-reference.html#includepath
Is it a template library?
Can you post a link to the source?

GroundZero

yeah will do give me a couple of minutes please :)

edit:

:-1: error: cannot find -lsfml-freetype

is the error I am receiving after doing:

@LIBS *= -L"SFML/libs/" -lsfml-freetype -lsfml-glew -lsfml-jpeg -lsfml-openal32 -lsfml-sndfile@

In my .pro file.

The .lib files I included:

I downloaded this SFML : https://github.com/LaurentGomila/SFML/tarball/master
The page it self is located here: http://www.sfml-dev.org/download.php -> SMFL 2.0 Snapshot

My code at this moment:

@#-------------------------------------------------

Project created by QtCreator 2011-08-22T12:53:05

#-------------------------------------------------

QT += core gui

TARGET = game
TEMPLATE = app

SOURCES += main.cpp

HEADERS +=

LIBS *= -L"SFML/libs/" -lsfml-freetype -lsfml-glew -lsfml-jpeg -lsfml-openal32 -lsfml-sndfile
@

and the .cpp file

@#include <SFML/Window.hpp>

int main()
{
// Create the main window
sf::Window App(sf::VideoMode(800, 600, 32), "SFML Window");

// Start main loop
bool Running = true;
while (Running)
{
    App.Display();
}

return EXIT_SUCCESS;

}

I also uploaded a copy of my whole directory incl. libs, .h and .cpp files here:

I am using Microsoft Windows 7 Professional with Qt Creator :)

octal

You should link against .a libraries instead of .lib ones (located in libs-mingw)

koahnig

I guess octal is correct.
I have no experience with mingw on win7. I have visual studio installed there. On ubuntu I am using qt creator.

GroundZero

Yeah I tried that... when i remove all .lib and paste the new files (.a) it still asks for -lsfml-freetype :P

octal

Mhh yes, you're linking the wrong libraries, those are the dependancies needed to compile the SFML.

Since I've never used the SFML 2.0, you should follow the "official instructions":http://www.sfml-dev.org/tutorials/2.0/compile-with-cmake.php

GroundZero

Oke, will give that one a try :D thanks!!!
but...

set PATH=%PATH%;your_mingw_folder\bin
cmake

Cant find where to fill in that path and stuff... and where do i type in the command cmake?

koahnig

path is the environment variable path in your example. So with
@ set PATH=%PATH%;your_mingw_folder\bin@
you are extending that the path setting in your environment.
cmake you have to type on the command prompt.
[edit] Are you working on the command prompt?
