Title: SFML 2 and FBOs?
Post by: PaloDeQueso on February 21, 2011, 10:41:30 pm

I recently decided to update to SFML2 because of the RenderImage feature so I can finally render text to images once again. (Something I've missed from my SDL days) But as soon as I did, my FBOs are always rendering blank. NOTE: I didn't try to change anything, I just turned off all text features that I had before and recompiled my Engine with SFML2. Suddenly my deferred renderer is completely broken. Anyone else experience any issues with SFML 2 and FBOs?

If you mix SFML and OpenGL you must save/restore your states, because SFML will mess them up (and vice versa). There are the SaveGLStates and ResotreGLStates functions for that.

Thanks for the tip...

On that note I decided to try using SFML2 again... unfortunately I'm stuck in winblows here at work, and am using MinGW.

- I compiled SFML2 from the latest snapshot.
- Copied the includes, libs, and bins to the mingw and system32 directories and removed the old libsfml files

now I'm getting this...

..\..\ElementGames\Engine\libegengine.a(Application.cpp.obj):Application.cpp:(.text+0x238): undefined reference to `_imp___ZN2sf12RenderWindowC1ENS_9VideoModeERKSsmRKNS_14WindowSettingsE'

But as far as I can tell, I'm not using WindowSettings anymore?

I'll grep through my code to double check... but I wanted to throw this one out there. It's something I didn't encounter last time I tried SFML2.

Here is my RenderWindow create line:

Code: [Select]

sfml_application = new sf::RenderWindow(sf::VideoMode(resolution_width, resolution_height), "ElementGamesTest", ((fullscreen) ? sf::Style::Fullscreen : sf::Style::Close));

I fixed that last issue, sorry for the spam on the forum without proper debugging/coding practices. I love this library and thanks for all of the quick help!
