Fuck me - es sieht so aus als ob ich nur noch ein glewInit() gebraucht hätte. Gab sonst einen Speicherzugriffsfehler.

Hmm. It now compiles. At least i get a binary. But i get an error:

glGenBuffers not resolved and many other things too.

I am linking GLEW GL and GLU beside all the sfml stuff.

General / OpenGL - how to make it work
« on: October 29, 2014, 06:47:19 pm »

I just want to learn some modern OpenGL using Linux and SFML. I am trying to use the OpenGL 4.0 tutorial i found on http://antongerdelan.net/opengl/.

Now i am trying to compile the program and get like for every Opengl-Command:

cpp:18:26: error: ‘glGenBuffers’ was not declared in this scope

I do not know how to proceed from here. Any ideas?

I could post the whole program code if needed and maybe the linker options too.

General / Tiled Map
« on: February 22, 2011, 02:59:37 am »
How does  sf::RenderImage work exactly?
Or to keep things simple... if i do something like

Code: [Select]

for( y = 0; y<height; y++)
    for(x = 0; x <width; x++)
         renderImage.Draw( tile[y][x].sprite);

... render to window ...

will this be more effective than rendering directly to screen?[/code]

General / Tiled Map

Hi, i wanted to render a Tiled map, each tile 12*12px.
My first way was to draw every single tile itself. But i think this may cause too many drawcalls,
any better ways?

Audio / Sound in games, beginners question
« on: December 21, 2010, 12:07:24 am »
Well i havent found an answer to this .

If i have a look at the sound tutorial eg, i see the  sleep() method.
Why is it there exactly?

(it says leave some time for other threads)
would playing the sound without sleep take over the whole cpu and nothing else could be done (similiar to fractals?)

should sound be handled in an extra thread when programming a game?

Python / PySFML and Installation
« on: July 07, 2010, 04:41:52 pm »
Does SFML work with Python3.x?

Moreover what is the link in the wiki to see how to compile the sourcecode from the svn 2.0 properly?

Thx in advance !

General discussions / DirectX vs SFML
« on: April 19, 2010, 06:34:42 am »
I dont know if u understand german but this might be interesting for you:


in short:

sfml would be very slow compared to directX tested on WinXP and Win2000, this guy is wondering why

General discussions / Compiling and deleting
« on: March 16, 2010, 02:23:49 pm »
Hello, at the moment i use sfml 1.4, because it is standard in debian.

But now i want to try out the newer sfml-versions 1.5 and 2.0.
unfortunately i do not exactly know what will happen to my system if i compile sfml on myself.

If done so how could i remove it properly?

I´d like to have just one folder containing all used headers and .so files so that i easily could delete this folder to remove sfml again.

Is that tricky or hard to realize? And if not what can i do?

General / OpenGL - Question concerning Image::bind() a bit
« on: January 15, 2010, 12:06:48 pm »
o yeah that worked,

but what should i use instead of sf::Image?

the only alternative i found was


but it sounds quite difficult.

What is the standard for 3d?
