The GameDev.net FreeBook is relevant to game designers, developers, and those interested in learning more about the challenges in game development. We know game development can be a tough discipline and business, so we picked several chapters from CRC Press titles that we thought would be of interest to you, the GameDev.net audience, in your journey to design, develop, and market your next game. The free ebook is available through CRC Press by clicking here. The Curated Books The Art of Game Design: A Book of Lenses, Second Edition, by Jesse Schell Presents 100+ sets of questions, or different lenses, for viewing a game’s design, encompassing diverse fields such as psychology, architecture, music, film, software engineering, theme park design, mathematics, anthropology, and more. Written by one of the world's top game designers, this book describes the deepest and most fundamental principles of game design, demonstrating how tactics used in board, card, and athletic games also work in video games. It provides practical instruction on creating world-class games that will be played again and again. View it here. A Practical Guide to Indie Game Marketing, by Joel Dreskin Marketing is an essential but too frequently overlooked or minimized component of the release plan for indie games. A Practical Guide to Indie Game Marketing provides you with the tools needed to build visibility and sell your indie games. With special focus on those developers with small budgets and limited staff and resources, this book is packed with tangible recommendations and techniques that you can put to use immediately.

QMake and SFML linking under windows

3 posts in this topic

Hi guys

I tried to link to the SFML library with a QTCreator project under windows. And it didn't work.
QTCreator doesn't allow me to select .dll files, the wizard only accepts .lib.

So this is what i did:[list]
[*]I downloaded SFML 1.6 for MinGW and put it in the project folder under /lib.
[*]I have MinGW installed and selected it as my compiler/builder in the project settings.
[*]I tried building the program with both writing down the relative path to the dll, and by using -L(path to /lib) -lmylib... with the first one, it said it didn't find sfml-window.dll, with the second one, it didn't find sfml-graphics.dll when trying to run the exe.
[/list]
I am guessing, i am doing something very simple very wrong. Here are the relevant files:

project file
[SPOILER]
[CODE]

TEMPLATE = app
CONFIG += console
CONFIG += debug_and_release
#QT += opengl
SOURCES += main.cpp \
sources/nestedtest/myclass.cpp
HEADERS += \
sources/nestedtest/myclass.h
win32-g++ {
CONFIG(release, debug) {
TARGET = tryout_release
} else {
TARGET = tryout_debug
}
INCLUDEPATH += $$PWD/lib/SFML-1.6/include
DEPENDPATH += $$PWD/lib/SFML-1.6/include
LIBS += -L$$PWD/lib/SFML-1.6/lib/ -lsfml-graphics -lsfml-window -lsfml-audio -lsfml-system
#LIBS += $$PWD/lib/SFML-1.6/lib/sfml-graphics.dll
#LIBS += $$PWD/lib/SFML-1.6/lib/sfml-window.dll
#LIBS += $$PWD/lib/SFML-1.6/lib/sfml-audio.dll
#LIBS += $$PWD/lib/SFML-1.6/lib/sfml-system.dll
}
[/CODE]
[/SPOILER]

main.cpp
[SPOILER]
[CODE]
#include <iostream>
#include <SFML/Graphics.hpp>
#include <QDebug>
using namespace std;
// Creates the RenderWindow with a size of 800*600 and 32 bits colordepth as
// a global variable
sf::RenderWindow App(sf::VideoMode(800, 600, 32), "Jump & Run Tutorial");
// The event that we use to catch the closing of the game
sf::Event Event;
bool init() {
// return that initialization was successful
return true;
}
void update() {
// look for events
while (App.GetEvent(Event))
{
// if the user did close the window (by pressing the x button of the
// window, e.g.), close the game
if (Event.Type == sf::Event::Closed) {
App.Close();
}
}
}
void draw() {
// Clear the graphics window
App.Clear();
// Everything that needs to be drawn will be here later
// Actualize the display
App.Display();
// Look the the console window to see this output
//qDebug()<<"Just to see qDebug in action.";
}
int main()
{
bool initSuccess=init();
// if an error occured during init() close the game
if (!initSuccess){
App.Close();
}
// gameloop till game is closed
while (App.IsOpened())
{
update();
draw();
}
return EXIT_SUCCESS;
}
[/CODE]

You don't link a DDL, you link the library file corresponding to the DDL. Did you read the instruction on SFML website?

[url="http://www.sfml-dev.org/tutorials/1.6/start-vc.php"]http://www.sfml-dev.....6/start-vc.php[/url]

Edit: well, the link I provided is for VS, but the idea is the same... Edited by Faelenor

I don't use visual studio, I use MinGW. There are no .lib files (all i've found about those suggested they are proprietary VS libraries).

I read the instructions, I can compile and link samples via GCC, but I want to do it with QMake. I haven't found a satisfying tutorial for QMake, the only thing I've found was to put the dlls in the windows system folder, which i would like to avoid.

E:The strange thing is i can compile, the linker too finishes without an error. I am guessing the exe doesn't know where to find the dll's. Edited by Bluefirehawk

In that case, you just have to copy the DDL in your .exe folder? Or make sure the startup directory is the one containing the DDL?
