General / OS X: crash when resize window to minimal size

« on: January 30, 2015, 05:01:08 pm »

SFML from github (master).

When I try resize window to minimal size (i do it fast), program crashes.

UPD: I think is a bug of the OS, because with GLFW i've got same thing.

Code:

#include <SFML/Window.hpp>

int main()
{
    sf::Window window(sf::VideoMode(800, 600), "OpenGL");

    bool running = true;

    while (running) {
        sf::Event event;

        while (window.pollEvent(event)) {
            if (event.type == sf::Event::Closed) {
                running = false;
            }
        }
    }

    window.close();

    return 0;
}
 

Error:

General / runtime error with code from graphics tutorial

« on: January 29, 2015, 03:29:02 pm »

code from http://www.sfml-dev.org/tutorials/2.1/graphics-draw.php:

#include <SFML/Graphics.hpp>

void renderingThread(sf::RenderWindow *window)
{
    while (window->isOpen()) {
        window->clear();
        window->display();
    }
}

int main()
{
    sf::RenderWindow window(sf::VideoMode(800, 600), "OpenGL");

    sf::Thread thread(&renderingThread, &window);
    thread.launch();

    while (window.isOpen()) {
        sf::Event event;

        while (window.pollEvent(event)) {
            if (event.type == sf::Event::Closed) {
                window.close();
            }
        }
    }

    return 0;
}

Error when close window: Pure virtual function called! because window is closed (and may be deleted), but pointer *window in second thread are still used

i change code, add mutex, and now it works fine, but i'm not sure is this right way to use mutex here?

// main thread
...
if (event.type == sf::Event::Closed) {
    mutex.lock();
    window.close();
    mutex.unlock();
}
...

// second thread
...
    mutex.lock();
    window->clear();
    window->display();
    mutex.unlock();
...

General / Can't build simple app on OS X (SFML from master)

« on: January 29, 2015, 02:19:54 pm »

Hi!

SFML compiled from sources (github master) using clang and libc++ (may be i do it wrong, but simple app with window compiles succefull).
When i try to compile anything with code:

sf::VertexArray triangle(sf::Triangles, 3);

ive get error:

Undefined symbols for architecture x86_64:
  "sf::VertexArray::VertexArray(sf::PrimitiveType, unsigned int)", referenced from:
      renderingThread(sf::RenderWindow*) in main.cpp.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make[2]: *** [Engine] Error 1
make[1]: *** [CMakeFiles/Engine.dir/all] Error 2
make: *** [all] Error 2

Compiled with CMake:

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11 -Wall -stdlib=libc++")

It seems like some SFML parts compiled with 32bit arch instead of 64..

General / Window size on OS X & Retina display

« on: January 26, 2015, 05:02:26 pm »

Hi.

Tested on 2.2 (from sources) & github master.

Code below makes window with size 400x300:

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

Of course in real (hardware) pixels it have normal size (800x600 real pixels), but by default OS X scales resolution. Same problem with sprites & other.

So can the SFML detect that need to scale all sizes automatically when i run app on retina display and non-retina display?
