General / Re: not linking to OpenGL library

Hi Laurent thank you for replying.
I red the OpenGL tutorial but I had no idea what it meant by "You will then need to link your program to the OpenGL library". I am new to programming and linking but it is what I like now.

All the information included here pointed me in the right direction.
Thank you for your effort in keeping Good SFML Documentation available. I appreciate it.

General / Re: not linking to OpenGL library

« on: May 01, 2013, 05:26:17 am »

I finally got to compile the Opengl examples from SFML 2.0.
For those still having trouble here is what i did working with code::blocks 12.11:
On the code::blocks Menu go to Project->Build options...
On the 'Project build options' window select opengl which is the upper level of the tree on the left side of the screen.
Select 'Linker settings' which is at the right side of the tree.
On the section labeled 'Link libraries:' click on the 'Add' button and write your library's path in my case it was:
C:\Windows\System32\opengl32.dll
Do it again for the file:
C:\Windows\System32\glu32.dll

Happy SFML\OpenGL compiling!

General / not linking to OpenGL library

« on: May 01, 2013, 04:45:16 am »

Hi I am using windows Vista Ultimate, and code::blocks 12.11 with MinGW included(gcc vesion 4.7.1)
I am using the SFML binaries from the file 'SFML-2.0-windows-gcc-4.7-tdm-32bits.zip'

I have No previous OpenGL knowledge but I would like to learn.

1.- An OpenGL application automatically made with code::blocks' OpenGL project wizard compiles fine on my PC.
2.- Most examples included in SFML2.0 compile fine in my PC too except for those using OpenGL and the headers: #include <SFML/OpenGL.hpp>, and #include <SFML/Config.hpp>.
3.- I Noticed files like System.hpp and Window.hpp have corresponding library files (*.a) but I have no .a file corresponding to Opengl.hpp and neither for Config.hpp.
How do I get those libraries and how do I link to them in code:blocks.

I get errors such as:
C:\Users\Aldito\Documents\codeblocks\opengl\main.cpp|40|undefined reference to `glGenTextures@8'|
C:\Users\Aldito\Documents\codeblocks\opengl\main.cpp|41|undefined reference to `glBindTexture@8'|
C:\Users\Aldito\Documents\codeblocks\opengl\main.cpp|42|undefined reference to `gluBuild2DMipmaps@28'|
C:\Users\Aldito\Documents\codeblocks\opengl\main.cpp|43|undefined reference to `glTexParameteri@12'|

This is an issue I have tried to figure out on my own for a couple of days without success.
Thank you in advance to anyone that can help.
Antonio.
