Thank god. It's really getting boring here without being able to continue my work. Thanks for the status report.

I made the first fix. I still have an error from times to times (otherwise it works fine), but at least it should no longer be related to VideoMode, like the backtrace showed in one of your previous posts.

That's the first step, now it's going to be more difficult if X is really unable to handle multi-threading properly, as all the windows and contexts in SFML are shared and thus use the same X display :?

I guess you can work around that by using mutexes, so that you can continue to work until I fix all this stuff.

Hey look at this:

I made another fix, this one seems to solve your problem at 100% (sf::Context instances now have their own connection to the X display).

There's just one fix to be done (for using multiple windows in different threads) and everything should be ok

I commited the last fix. Enjoy

(and pleeeeease confirm that everything works fine now)

Thank you very much for your work! I'll check if that fixes my problems later, but I highly think so, since you fixed exactly what I also thought would be the issue.

Awesome!

You did a great job, my application is running flawlessly now.

Okay, not completely: I've still got a memory violation when the program is about to close (i.e. objects get destructed). But since I don't know if that's caused by SFML, I'll have to investigate that. Too bad I'll be away for a week (holiday trip).

Again, thank you very much for the fix. You saved my semester break.

I'm glad to hear that

Back from holiday, tested application, very happy.

All bugs are gone now, thanks again for your good work.

I don't know if it's related to this fix you just made, but I have a "GLXBadContext" error whenever I run an SFML app. The opengl sample doesn't work (the only one I tested), but glxgears does, so I believe it comes from SFML.

Can you give more informations about your configuration? Which version / revision of SFML are you using?

Did you try a complete rebuild (make clean)?

Kreeg · « **Reply #43 on:** August 19, 2009, 03:29:05 pm »

Yes. Here's my uname -a.

Did it work with SFML 1.5?
