SFML 2 for OS X comes true!

[Ceylo]

Indeed it is .

[Hiura]

Now about

Creating a window and then calling sf::Window::Create() on the same window object makes the app crash randomly.

Does the following code crash ?

Code: [Select]

#include <SFML/Window.hpp>

int main(int, char**) {
   
    sf::Window window(sf::VideoMode(800, 600), "SFML");
   
    sf::Clock clock;
    while (clock.GetElapsedTime() < 100.f) {
        window.Create(sf::VideoMode(800, 600), "SFML");
        sf::Sleep(0.1); // not required.
    }
   
    return 0;
}I can't reproduce the bug here.

[Ceylo]

Your code doesn't crash, but the following one does:

Code: [Select]

#include <SFML/Window.hpp>
#include <SFML/OpenGL.hpp>

int main(int, char**) {
   
    sf::Window window(sf::VideoMode(800, 600), "SFML");
   
    sf::Clock clock;
    while (clock.GetElapsedTime() < 100.f) {
        window.Create(sf::VideoMode(800, 600), "SFML");

sf::Event ev;
while (window.GetEvent(ev)) {

}

glClear(GL_COLOR_BUFFER_BIT);
window.Display();
        sf::Sleep(0.1); // not required.
    }
   
    return 0;
}

P.S.: it seems to crash as soon as you add the event handling code.

[Hiura]

WHaou! That was some serious bug! (5 different backtraces for the same bug (love memory guard) plus one other bug which gave me some weird «-[NSConcreteValue windowDidResignKey:] unrecognized selector sent to instance» comming from nowhere..) :shock:

Can you confirm it's working properly now ?

[Kolja]

Hey there!

Another Mac user here, I'll try to help with some testing when I find the time (currently it's exam time here though, so not now). But I'm really glad you are helping the OS X port along!

During my initial compile of the current SVN tarball I noticed (apart from the broken sndfile symlink) that all graphical examples only display something after the window has been obscured or moved - known bug or weird behavior on my system?

I'm on a MBP running 10.6.6 by the way, using the GeForce 9400M for now.

[Hiura]

Hi! Happy to see a new face.

I tried to reproduce the problem you described but I couldn't reproduce it (even with the tar.gz) and I have the same hardware/OS version.

Have you any other app non related to SFML that have the same behaviour ?
Maybe you haven't updated your driver ?
Any plugins ?

It's very weird..

[Kolja]

D'oh, sorry to have taken away your time. A reboot fixed it, now it works with both graphics cards. I'm not totally sure how such a bug "works" though, other hardware accelerated games worked fine.

[Kolja]

On an unrelated note, shaders in the examples directory are something SFML-specific, right? Because the example only tells me that shaders are unsupported on my system, but GLSL definitely works here ;-)
I only use SFML for audio, input and a cross-platform OpenGL context I do my own drawing in, so all the graphics and sprite features of SFML don't concern me too much.

[Hiura]

Same here -> added to my task list. I'll have a look soon.

It's working fine now, or at least... the given code does no more crash.

Hiura, thanks for your work on SFML2.

For reference, I am running OSX 10.6.4, gcc 4.2.1.  I was able to build the static libraries successfully using cmake -> unix makefiles.  However when trying to compile any of the graphical examples provided with SFML2, I get lots of undefined symbols.  I can paste the first third or so here:

I have not tried with the dynamic libraries yet, will do that asap.

Edit: There appears to be no problem linking against the dynamic libs, only when I uncheck "BUILD_SHARED_LIBS" in cmake and then compile the examples to I get these errors.[/b]

[Laurent]

There's no link step when creating static libraries, they are just archives of compiled files. Therefore, none of the external dependencies of SFML is "pre-linked", you need to link them to your final application.

Dyanmic libraries should be preferred, if you can use them. Static libraries are just a way to workaround the lack of shared library management on Windows and the mess it creates.

[Hiura]

If you guys haven't got the joystick working for Mac OS X, there is a sample here:
http://homepage3.nifty.com/ysflight/macdev/joystick/e.html

Thank you, I'll have a look but I think I won't use it – I prefer do it myself even I it takes time because I don't want external dependences, but this may be to be discussed if it is very adapted to SFML joystick backend, of course.

PS: Laurent, I see you're always the fastest, great job  
I'd like to emphasize this a lot :

Dyanmic libraries should be preferred, if you can use them.

(On Mac, you can put your app dependencies into your app bundle (the .app folder thus installing your app won't be difficult at all) so use shared/dynamic lib as often as possible. It might even have better overall performances.)

It should be a native example. There aren't any external dependencies outside the norm.
