Graphics / LoadFromFile undefined reference problem

« on: September 26, 2016, 11:03:36 pm »

I have no idea what to do. I tried loading images (bmp), music (wav) or font (ttf) with LoadFromFile function, but the compiler always spits out similar error.

|In function `main':|
C:\_stuff\code blocks\projects\game1\main.cpp|14|undefined reference to `sf::Texture::loadFromFile(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, sf::Rect<int> const&)'|
C:\_stuff\code blocks\projects\game1\main.cpp|15|undefined reference to `sf::Font::loadFromFile(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&)'|
 

This is how the source code looks:

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

int main()
{
    sf::Font font;
    sf::Texture hero_idle_texture;
    hero_idle_texture.loadFromFile("hero_idle.bmp");
    font.loadFromFile("arial.ttf");
    return 0;
}

I put files both in the obj file and in the exe file directory. I tried reinstalling SFML, compiler and Code::Blocks several times, but it didn't work.

I'm programming in Code::Blocks, using SFML 2.3.2 and my OS is Windows 10 64 bit.

I also tried to recompile SFML using CMake but I got this problem: http://stackoverflow.com/questions/39680283/cannot-generate-files-with-cmake-using-mingw-makefiles

Graphics / sf::RenderWindow problem

« on: April 11, 2015, 07:56:02 pm »

I apoligize for my laziness if a thread with this problem has already been created.

I have a problem with RenderWindow. Specifically, after compilation, I get a crash report like this:

gamePrototype.exe stopped working
An error caused a program to stop working correctly. Windows will close the program and notify you of available solutions.

The window doesn't want to open, but the console still works.
My code:

#include <SFML/Graphics.hpp>
#include <SFML/Audio.hpp>
#include <cmath>
#include <iostream>
float falling(float time)
{
    return 10*(time/1000);
}
int main()
{
    sf::RenderWindow window(sf::VideoMode(800, 600, 32), "My Window");   //1
    window.setFramerateLimit(60);
    sf::Texture texture;
    sf::Sprite sprite;
    sf::Clock clock;
    sf::Event event;
    texture.loadFromFile("cos.png");
    sprite.setTexture(texture);
    sprite.setScale(sf::Vector2f(0.1f, 0.1f));
    sf::RectangleShape rectangle(sf::Vector2f(30, 600));
    rectangle.setFillColor(sf::Color::Red);
    rectangle.setPosition(510,0);
    int a = -30, mode = 1;
    while (window.isOpen())
    {
        while (window.pollEvent(event))
        {
            if (event.type == sf::Event::Closed)
                window.close();
            if (sf::Keyboard::isKeyPressed(sf::Keyboard::F10))
                window.close();
        }
        if(mode==0)
        {
            if(sf::Keyboard::isKeyPressed(sf::Keyboard::Left))sprite.move(-4,0);
            if(sf::Keyboard::isKeyPressed(sf::Keyboard::Right))sprite.move(4,0);
            if(sf::Keyboard::isKeyPressed(sf::Keyboard::X))
            {
                sf::Time playerTime=clock.getElapsedTime();
                float time=playerTime.asMilliseconds();
                sprite.move(0,a+falling(time));
                mode = 1;
            }
            if(sprite.getPosition().x>510&&sprite.getPosition().x<540)
            {
                if(sf::Keyboard::isKeyPressed(sf::Keyboard::Up))mode = 2;
                if(sf::Keyboard::isKeyPressed(sf::Keyboard::Down))mode = 2;
            }
            clock.restart();
        }
        if(mode==1)
        {
            sf::Time playerTime=clock.getElapsedTime();
            float time=playerTime.asMilliseconds();
            if(sf::Keyboard::isKeyPressed(sf::Keyboard::Left))sprite.move(-4,0);
            if(sf::Keyboard::isKeyPressed(sf::Keyboard::Right))sprite.move(4,0);
            if(sprite.getPosition().y<500)
            {
                sprite.move(0,falling(time));
            }
            else mode = 0;
            if(sprite.getPosition().x>510&&sprite.getPosition().x<540)
            {
                if(sf::Keyboard::isKeyPressed(sf::Keyboard::Up))mode = 2;
                if(sf::Keyboard::isKeyPressed(sf::Keyboard::Down))mode = 2;
            }
        }
        if(mode==2)
        {
            if(sf::Keyboard::isKeyPressed(sf::Keyboard::Up))sprite.move(0,-4);
            if(sf::Keyboard::isKeyPressed(sf::Keyboard::Down))
            {
                if(sprite.getPosition().y<500)sprite.move(0,4);
                else mode = 0;
            }
            if(sf::Keyboard::isKeyPressed(sf::Keyboard::X))mode = 1;
            clock.restart();
        }
        window.clear(sf::Color::White);
        window.draw(rectangle);
        window.draw(sprite);
        window.display();
    }

    return 0;
}
// 1 = everything except for this line is alright
 

I use Code::Blocks.
