include guards causing my code to break? |  |

I am having a bit of trouble with some `#include` guards.
I am using SDL and have my code defined like this:   #include "SDL.h"   #if __MACOSX__   #define GL_GLEXT_PROTOTYPES   #include <SDL2/SDL_opengl.h>   #elif __ANDROID__   #include "SDL_opengles2.h"   #elif __LINUX__   #include "SDL_opengl.h"   #endif this is already a bit off because for example on macos x there is no SDL.h it's located at <SDL/SDL.h> for linux SDL.h work and for windows I don't even know just yet. with the above code I get   implicit declaration of some of the opengl functions error if I move the `#include SDL_openg.h` outside of the include guard things work just fine on linux but then there are the errors on mac. |

Maybe it would work better if you use "#if defined __MACOSX__" instead of "#if __MACOSX__" (etc.)? Chances are those defines are defined to empty values, and empty values do not evaluate to true for #if. eirik _______________________________________________ SDL mailing list http://lists.libsdl.org/listinfo.cgi/sdl-libsdl.org |

Just my 2 cents, ans slightly off-topic, but...
I think it might be a good idea not to use #ifdef's for include paths at all, and offset that to compiler flags (or appropriate settings for you IDE/whatever). I.e #include <SDL.h> gcc -I/usr/local/include/SDL2 On Sat, 14 Nov 2015 15:05:19 +0800 Owen Alanzo Hogarth wrote:

Also it looks looks you are mixing gles with gl - and if you are using any fixed function pipeline stuff that is no longer available in gles... this won't work, too.
I suppose you get those implicit decl errors on android? On Sat, Nov 14, 2015 at 7:00 PM, Driedfruit wrote:

Driedfruit that's actually a pretty good idea, I didn't think about that. I'll try that since I am using CMAKE.
M. Gerhardy I am only using opengles 2.0 and opengl 330 core that's the base line for this project. I don't do any fix function OpenGL. On Sun, Nov 15, 2015 at 5:00 AM, M. Gerhardy wrote:
