General / Re: New install of Qt 5.2.1 and SFML 2.1

« on: May 15, 2014, 10:27:21 pm »

I got it working.  Not sure what I did right.  There are a lot of conflicting posts in forums that approach the same sort of issues from different directions.  I think the most significant differences in solutions result from the differences in Windows applications and Linux applications.

The failure I was seeing as listed above was a result of not having the project configured correctly.  I didn't have the libs and dlls identified in the right places.

I think the most significant thing in the code was I needed to add sf::JoyStick::update() before the isConnected() line.  From what posts I found this only applies to the windows environment.

So after correcting the configuration and adding one line of code it is now functioning.  Now I am proceeding to add code to accept input from the joystick and provide that information to my application.

BTW..  I sort of figured you could use Qt and SFML in Express without the Qt plugin.  But you loose all of the visual capabilities of Creator.  As I am just beginning using Qt, the Creator has been a great help in building my application.  Maybe once I get comfortable enough with Qt I will consider using VS Express.  For the moment I'll stick with Creator.  Although the errors messages that come from Creator both during compile and execution leave a lot of confusion and create a lot of frustration for me.

Thanks for your responses.

I do not quite understand your configuration. You say that you have installed the MVSC (MSVC?) version of Qt, but then you say you are using Qt Creator.

This is not a problem at all. QtCreator can use both gcc and VC++.

OK, this must have changed since the last time I used Qt Creator.

Actually there is a version of Qt and Qt Creator that was built using MVSC 2010 available for download from the Qt webpage.  I needed that because a 3rd party API I am using was also built with MVSC 2010.  So in order to use Qt with my 3rd party product it has to be compatible.  I found out the hard way because I started off with the MinGW version first and nothing would link.

I am using Qt Creator because I don't have access to the full version of MVSC 2010 and the Qt plug-in does not work with express.  I don't have a choice.

I will try using debug.  My problem is I am a Java developer with minimal C++ training.  This is making a lot of things extremely difficult.  I find potential solutions to the challenges I am facing and 75% of them do not work.  So I am floundering a LOT..      It's educational and I am learning a lot but it sure is frustrating!!!

So it appears I have everything configured properly in the project file?

General / New install of Qt 5.2.1 and SFML 2.1

I'm not entirely sure where this question should go.  Since this is my first attempt at building a project with this configuration I thought I would put it in General.  It may belong in Window.

I have installed Qt.5.2.1 based on MVSC 2010, 32bit.  I also have installed SFML 2.1 based on MVSC 2010, 32bit.  I am new to Qt and Qt Creator but have been building successful example projects for a couple weeks now.  I am a Java programmer with some C++ education in the past.  I'm just now getting into it in a serious way.  My development is for a specific application that will run only in a windows 7 environment.  I needed access to Joystick input.  After several days of research I came across SFML.  It appears to be just what I am looking for. 

I set up a very simple project in Qt with a main window.  In the MainWindow constructor I put the following code:

    if(sf::Joystick::isConnected(0))
        qDebug() << "Joystick 1 is connected";
    else
        qDebug() << "Can't find a joystick";

The include is:

#include <SFML/Window.hpp>

In my project file I have:

LIBS += -L"C:/SFML-2.1/lib/" -lsfml-window-d

INCLUDEPATH += "C:/SFML-2.1/include"
DEPENDPATH += "C:/SFML-2.1/include"

It builds without error.  However when I try to run it from Qt Creator it crashes.  The actual messages are:

Starting D:\QT-Projects\examples\build-JoystickSFML-Desktop_Qt_5_2_1_MSVC2010_32bit_OpenGL-Debug\debug\JoystickSFML.exe...
The program has unexpectedly finished.
D:\QT-Projects\examples\build-JoystickSFML-Desktop_Qt_5_2_1_MSVC2010_32bit_OpenGL-Debug\debug\JoystickSFML.exe crashed

What am I doing wrong?
