compile SFML in xcode for iOS, OpenGL/glu.h file not found.

Why ... iOS not have glu support?

I don't remember why it is not done automatically, but it seems that you have to define the SFML_OPENGL_ES macro in your project settings.

I compared the different TargetConditionals.h (included in SFML/Config.hpp) on my system. Apparently, the one in /usr/include (or in 10.9 SDK) reads

    #define TARGET_OS_MAC               1
    #define TARGET_OS_WIN32             0
    #define TARGET_OS_UNIX              0
    #define TARGET_OS_EMBEDDED          0
    #define TARGET_OS_IPHONE            0
    #define TARGET_IPHONE_SIMULATOR     0

the one in /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS.sdk/usr/include/TargetConditionals.h reads a little bit differently

    #define TARGET_OS_MAC               1
    #define TARGET_OS_WIN32             0
    #define TARGET_OS_UNIX              0
    #define TARGET_OS_EMBEDDED          1
    #define TARGET_OS_IPHONE            1
    #define TARGET_IPHONE_SIMULATOR     0

and of course the one in the iPhone Simulator SDK reads

    #define TARGET_OS_MAC               1
    #define TARGET_OS_WIN32             0
    #define TARGET_OS_UNIX              0
    #define TARGET_OS_EMBEDDED          0
    #define TARGET_OS_IPHONE            1
    #define TARGET_IPHONE_SIMULATOR     1

Now, I haven't tested but I guess setting correctly the SDK to use would fix this issue.

@smartly, how did you set up your project?

[Laurent]

SFML_OPENGL_ES is never defined, even if SFML_SYSTEM_IOS is correctly defined. So it's not a problem with TargetConditionals.h, it's just that it has to be done manually.

[Hiura]

Damn, I was looking at OpenGL.hpp and not GLExtensions.hpp...

I'm wondering though: would it make sense to define SFML_OPENGL_ES in Config.hpp along with SFML_SYSTEM_IOS? (And maybe the same for Android?) Because, unless I'm mistaken, on those OSes only OpenGL ES work, right?

[Laurent]

Yes, that's why I said

I don't remember why it is not done automatically
