General / ZipLoader

« on: December 18, 2009, 05:47:01 pm »

Hi,

I was trying to test the exemple of the ZipLoader working with zlib and minizip.

I am not able to compile it on windows/linux.

I have downloaded zlib123.zip http://www.winimage.com/zLibDll/zlib123.zip  on linux.

I have no idea why it doesnot work.

Thanks

Graphics / sfml and opengl

« on: December 11, 2009, 05:07:43 pm »

hello.

I'm discovering sfml lib and i would like to be able to use opengl.

I pasted the code of the tutorial (http://www.sfml-dev.org/tutorials/1.5/window-opengl-fr.php).

I was not compiling because of errors during the linkage.

Code: [Select]


Error 1 error LNK2001: unresolved external symbol __imp__glDeleteTextures@8 main.obj
Error 2 error LNK2001: unresolved external symbol __imp__glClearDepth@8 main.obj
Error 3 error LNK2001: unresolved external symbol __imp__glClear@4 main.obj

Error 19 fatal error LNK1120: 18 unresolved externals



So i downloaded the glut lib found there : http://www.xmission.com/~nate/glut.html

I was surprising to see that the lib was very old (2001... !!!).

Then, i added this include to the code.

which redirect to what i downloaded.

#include <gl/glut.h>

And, miracle, the compilation works.

Is all i did is right ? Did i did anything wrong ?

Because when i stop the application, it crash.

I breakpoint the executation, i saw the error was after the main return.

If anybody has any idea ?

Thanks


Ps. I'm working with Seven and VisualStudio 2008
