General / SFML with Steam SDK crash on linux.

« on: March 06, 2022, 11:33:25 pm »

Hi. I am developing my first game for steam. It's a 2D game with SFML and OpenGL in Linux.

I am developing in Linux Mint with XFCE:

OS: Linuxmint 20.3 una
Kernel: x86_64 Linux 5.4.0-100-generic
Uptime: 52m
Packages: 3127
Shell: bash
Resolution: 3286x1080
DE: Xfce
WM: Xfwm4
WM Theme: Mint-Y
GTK Theme: Mint-Y [GTK2]
Icon Theme: Mint-Y
Font: Ubuntu 10
Disk: 383G / 598G (68%)
CPU: Intel Core i5-3330 @ 4x 3.2GHz [51.0°C]
GPU: NVE4
RAM: 3675MiB / 15971MiB
 

I have one C++ project using the QTcreator IDE. I compile SFML for my linux and I am using the lates version 2.5.1.
I download the steam SDK from this link https://partner.steamgames.com/downloads/steamworks_sdk.zip and I attach the library in my QTcreator project.

The problem is when I add the steam lib it crash. In debug it crash when I declare the sf::RenderWindow window;

I create another project with just an SFML example:

#include <SFML/Graphics.hpp>

int main()
{
    // create the window
    sf::RenderWindow window(sf::VideoMode(800, 600), "My window");

    // run the program as long as the window is open
    while (window.isOpen())
    {
        // check all the window's events that were triggered since the last iteration of the loop
        sf::Event event;
        while (window.pollEvent(event))
        {
            // "close requested" event: we close the window
            if (event.type == sf::Event::Closed)
                window.close();
        }

        // clear the window with black color
        window.clear(sf::Color::Black);

        // draw everything here...
        // window.draw(...);

        // end the current frame
        window.display();
    }

    return 0;
}
 

And I attach the SFML and Steam SDK in my project using this command in project.pro:

LIBS += -lsfml-system -lsfml-window -lsfml-graphics

LIBS += -L$$PWD/lib/linux64/ -lsdkencryptedappticket -lsteam_api
 

It compiles very good, but when I run the project in debug mode, it crash exacly in this line:

sf::RenderWindow window(sf::VideoMode(800, 600), "My window");

Have someone try to make an SFML project with steam SDK in linux?
I try compile and run it in release mode but in crashes aready.

System / Wrong key pressed in Linux Mint with XFCE 4.15.0-20-generic #21-Ubuntu (solved)

Hi.
I am using SFML to make a game where the player can write text. I am making a text field to get the pressed keys from keyboard. I am having some problem with my ABNT2 keyboard.

I write this code for test:

#include <SFML/Graphics.hpp>
#include <SFML/Config.hpp>

int main()
{
    // create the window
    sf::RenderWindow window(sf::VideoMode(800, 600), "My window");

    printf("\n%u %s %s SFML version == %u.%u.%u\n",__LINE__,__FILE__,__func__
           ,SFML_VERSION_MAJOR
           ,SFML_VERSION_MINOR
           ,SFML_VERSION_PATCH
           );fflush(stdout);

    // run the program as long as the window is open
    while (window.isOpen())
    {
        // check all the window's events that were triggered since the last iteration of the loop
        sf::Event event;
        while (window.pollEvent(event))
        {
            // "close requested" event: we close the window
            if (event.type == sf::Event::Closed)
                window.close();

            //read the key pressed
            if(event.type == sf::Event::KeyPressed){
                printf("\n%u %s %s Key Pressed code == %d",__LINE__,__FILE__,__func__
                       ,event.key.code
                       );fflush(stdout);
                if (sf::Keyboard::isKeyPressed(sf::Keyboard::Tilde)){
                    // left key is pressed: move our character
                    printf(" TILDE PRESSED");fflush(stdout);
                }
                if (sf::Keyboard::isKeyPressed(sf::Keyboard::Quote)){
                    // left key is pressed: move our character
                    printf(" QUOTE PRESSED");fflush(stdout);
                }
            }
        }

        // clear the window with black color
        window.clear(sf::Color::Black);

        // draw everything here...
        // window.draw(...);

        // end the current frame
        window.display();
    }

    return 0;
}
 

When I run the program, I press first the quote key '´' one time and then I press the tilde key '~' and I have this return:

$ ./helloSFML

9 main.cpp main SFML version == 2.5.1

28 main.cpp main Key Pressed code == -1 TILDE PRESSED
28 main.cpp main Key Pressed code == -1^C

Is this a problem with the last SFML version? Maybe I could try another old version.
How can I solve this problem?

I am using linux mint "4.15.0-20-generic #21-Ubuntu SMP Tue Apr 24 06:16:15 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux" with XFCE 4.12 with G++ "g++ (Ubuntu 7.4.0-1ubuntu1~18.04.1) 7.4.0".

Thanks.

Graphics / JPEG error in Windows 64 bits

« on: February 24, 2015, 04:33:28 pm »

Hi. I am making a Game Engine for my Conclusion Work in College. To be multi-plataform I chose SFML to make Linux and Windows versions of the same game.

I create a simple plataform project to show the Game Engine features. I am using both JPEG and PNG files to create the game design.

In Linux 64 bits the game runs OK. In Windows I use the MinGW 32 and 64 for Windows 32 and 64 versions and I have this problem.

SFML return this error message in Windows 64 version:

Failed to load image from memory. Reason : JPEG format not supported (progressive)

Why?
