glu.h MinGW

[lancel00t]

It seems that glu.h with MinGW is also broke in this release of SFML V 1.1. Compiling opengl.cpp using default instructions does not work using MinGW. A failed compilation generates error messages from glu.h in addition to glBuild2DMipmaps and gluPerspective not being found, most likely because glu.h is broken in terms of it's implementation with SFML.

Thanks!

[Laurent]

It's not broken, in fact I just forgot to include glu.h (I removed it from glew.h and forgot to update the demos sources... shame on me). To get a portable include filename you can write this :

Code: [Select]

#include SFML_GLU_HEADER

[lancel00t]

Even after including #include SFML_GLU_HEADER appropriatley I get the following compiler output:

Code: [Select]

[Laurent]

Do you include it before the SFML headers ? It should be after, because in Windows the GL / GLU headers first need windows.h to be included (which is done by the SFML headers).

[lancel00t]

It does not work either way; placing before or after.

[Laurent]

Hmm... Is this GLU header working in a project not using SFML ?

[Laurent]

Sorry, this was my fault.

In fact, I removed the glu.h include from glew.h (to avoid unnecessary compile errors for people who don't have GLU installed), but glew.h then removes the Windows-specific macros needed for glu.h. To fix it, you need to comment this code at the end of SFML/Window/glew/glew.h :

Code: [Select]

#ifdef GLEW_APIENTRY_DEFINED
#undef GLEW_APIENTRY_DEFINED
#undef APIENTRY
#undef GLAPIENTRY
#endif

#ifdef GLEW_CALLBACK_DEFINED
#undef GLEW_CALLBACK_DEFINED
#undef CALLBACK
#endif

#ifdef GLEW_WINGDIAPI_DEFINED
#undef GLEW_WINGDIAPI_DEFINED
#undef WINGDIAPI
#endif

#undef GLAPI

[lancel00t]

Thanks Laurent!

[NickZA]

Hi

Be gentle with me here, I'm lost as to how to get this going. Laurent, when you said to include

Code: [Select]

#include SFML_GLU_HEADER

Do you mean directly after

Code: [Select]

#include <SFML/Window.hpp>
?


(I made the change as above, also commented out the lines you mentioned in glew.h, but no go)

Did I have to change anything else like including glew.h in main.cpp, or changing anything else in my build settings, environment settings etc.?


Please help. I would really like to try out this library.  :?

Thanks,

-Nick

:oops: right, okay, I hadn't included all libs in my compiler/linker settings... ahem.

I have it compiling, but when it attempts to run it returns with error code 1.... The window flicks out within about a 1/4 second of it appearing.

Any help would be appreciated.
