[SDL] Help with SDL2_gfx on OS X

Hello,

Not sure if this is the right place to ask this, but I’m having much trouble trying to use sdl2_gfx on Xcode 8, I really can’t figure it out, and... well, the documentation or help in general for os x users is…. pretty discreet.

If someone can help, I’ll be forever grateful.

what exactly is the problem ?

i have it running, but I added a whole bunch of extra routines so sending over my version wouldn’t help much.

i just realized your stackoverflow line was a link to the issue, not some sort of signature in your mail :-)

I never use the dylib target, only the framework. Is there a reason you don’t use the framework ?

also : are you sure that you’re using the correct dylib ? In your mail project, right-click the included dylib and choose ‘show in finder’. Is this the version you compiled ?

Well Iâd love to use the framework, but there is none :/

I got the library here http://www.ferzkopp.net/wordpress/2016/01/02/sdl_gfx-sdl2_gfx/

Is there a simple mean to generate a .framework with this ? Or is this one part of the complicated cases ^^â ?

And yes Iâm using the correct lib, if what you mean is that I may have had wrong copies here and there. I juste have one version, in one place.

Thanks a lot for helping.
I guess Iâll try to generate a framework with what I have...

I relied to your stackoverflow post, but I think the solution is simple :

you are calling with as 1st parameter a RENDERER. The function header expects a SURFACE :

http://www.ferzkopp.net/Software/SDL_gfx-2.0/Docs/html/_s_d_l__gfx_primitives_8h.html#a4f7b717b958ef39bfc8c958476dd0de1

clearly defines the function as :

SDL_GFXPRIMITIVES_SCOPE int filledCircleColor ( SDL_Surface * dst,
Sint16 x,
Sint16 y,
Sint16 rad,
Uint32
color

)

Well I’d love to use the framework, but there is none :/

Yes, sorry, but I tried both :/
With a surface it says Â« no matching function call Â», it doesnât exist.

And the primitives header file for SDL2_gfx shows this :

SDL2_GFXPRIMITIVES_SCOPE int pixelRGBA(SDL_Renderer * renderer, Sint16 x, Sint16 y, Uint8 r, Uint8 g, Uint8 b, Uint8 a);

SDL2_GFXPRIMITIVES_SCOPE int filledEllipseRGBA(SDL_Renderer * renderer, Sint16 x, Sint16 y,
Sint16 rx, Sint16 ry, Uint8 r, Uint8 g, Uint8 b, Uint8 a);

Apparently it used to ask for a surface in SDL, but it changed to a renderer with SDL2.

hm, weird… how did you manage to get your code compiled/linked when passing a surface as first parameter ?

my guess is that you have two versions of SDL_gfx and the headers/libs don’t match ?

Post by Alice Probst

With a surface it says « no matching function call », it doesn’t exist.
SDL2_GFXPRIMITIVES_SCOPE int pixelRGBA(SDL_Renderer * renderer, Sint16 x, Sint16 y, Uint8 r, Uint8 g, Uint8 b, Uint8 a);
SDL2_GFXPRIMITIVES_SCOPE int filledEllipseRGBA(SDL_Renderer * renderer, Sint16 x, Sint16 y,

Iâm having much trouble trying to use sdl2_gfx on Xcode 8, I really canât figure it out

I simply ignored the precompiled library and instead included the SDL2_gfx files in my source tree:

SDL2_gfxPrimitives.h
SDL2_gfxPrimitives_font.h
SDL2_rotozoom.h
SDL2_gfxPrimitives.c
SDL2_rotozoom.c
