Linking SMFL Library to Qt on Windows machine

? Offline

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

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 ;)

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?

? Offline

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 :)

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.

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

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

? Offline

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?
