General / Re: WxWidgets/SFML program crashes with an X window system error (BadAccess)

« on: January 24, 2017, 09:16:56 am »

Hi,

I also have the same problem (with SFML 2.4.1) and I'm really concerned as my app rely very much on the link between SFML and wxWidgets. 

You can test the bug on Linux with my app (doesn't happen on my computer but it seems to happen on the lastest Ubuntu). The app is GDevelop.

General discussions / Re: SFML 3 - What is your vision?

sf::FileInputStream => std::ifstream (literally the same)
sf::InputStream => std::istream (literally the same)

I don't know if we can use the i(f)streams with Android and iOS, that's probably why they were created.

Also when will the SFML 3 project/branch be started?

Same question for me. I would really like to participe in SFML 3 development.

Graphics / Re: Undefined reference from loadFromFile

Maybe you build your project with C++11 but SFML is not built with C++11 (there have been a change in the ABI of the GCC standard lib with C++11).

That's because std::cout is slow (but it shouldn't be that slow however).

SFML development / Re: How should SFML handle non-legacy shaders?

« on: August 28, 2016, 09:33:14 am »

I definitely think SFML should switch to OpenGL 3 at least in the next major version.

Graphics / Re: Can't load a background

You need to draw the sprite between the clear and display statements.

By the way, you don't need to load the texture every frame. Just load it before the "while".

Obviously, you need to install the 32 bits (i686) versions of the packages to build a 32 bits SFML.

sprite = gameobject_sprite;
texture = gameobject_texture;
 

Here is the copy.

Graphics / Re: How to use OpenGL 4.5 in SFML, instead of OpenGL 3.3

« on: July 31, 2016, 10:29:34 am »

Does your graphic card really support creating an OpenGL 4.5 context ?

Can you show your code ?

Clearing is done like this :

glClearColor(0.2f, 0.3f, 0.3f, 1.0f); //Replace the values with the color :)
glClear(GL_COLOR_BUFFER_BIT);

Do you init GLEW ?

This is what you need to do to use GLEW (with modern OpenGL) :

glewExperimental = GL_TRUE;
if (glewInit() != GLEW_OK)
{
    std::cout << "Failed to initialize GLEW" << std::endl;
    return -1;
}

Thank you for your quick reaction.  I'll test it soon.

General / Re: [Android] Using c++11 and gnustl

« on: July 22, 2016, 02:06:33 pm »

I'm also concerned by this change in SFML as my app uses C++11 features.

EDIT : It seems that the android-cmake project (used by SFML) has dropped support for libc++...

EDIT2 : I've tested myself with gnustl_shared, it crashes (SIGABRT) on sf::String::~String

Audio / Re: Music not working

« on: July 17, 2016, 08:36:40 pm »

Look at the "WAV file audio coding formats compared" section in the wikipedia article. You'll see that audio can be encoded in many different ways in a WAV file. You can even put MP3 encoded audio inside a WAV file.
