openGL with sfml

sanji2011 (10)
i've managed to do some of the tutorials in the SML website but somehow i am not able to do the one involving OpenGL.
i am using the code::blocks IDE.

the tutorial is found here
http://www.sfml-dev.org/tutorials/1.2/window-opengl.php

}


at first i was getting many error message such as this:
C:\CodeBlocks\projects\test_sfml2\window.cpp|24|undefined reference to `glClearDepth@8'|


i tried to add -lGL to the linker options as suggested here:
http://www.cplusplus.com/forum/general/29578/


but i am getting this error message:
c:/mingw/bin/../lib/gcc/mingw32/4.5.2/../../../../mingw32/bin/ld.exe: cannot find -lGL

I believe the library is called "opengl32".

Also, just to say, that tutorial is out of date :P You should read the version 1.6 tutorials ;)

sorry, i may have pasted the wrong link in my first post. i was actually referring to the 1.6 tutorials.

btw, thanks for the suggestion, i am now able to compile the example successfully

for those who might encounter the same problem:
i added the following in the linker options:

-lopengl32
-lglu32
