Help with SDL2_gfx on OS X

Alice_Probst · October 2, 2016, 5:34pm

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.> On 02 Oct 2016, at 19:34, Alice Probst wrote:

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 ?> On 02 Oct 2016, at 19:34, Alice Probst wrote:

Well I?d 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 ^^? ?

And yes I?m 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 I?ll 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 :

clearly defines the function as :

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

Yes, sorry, but I tried both
With a surface it says ? no matching function call ?, it doesn?t 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 ?> Yes, sorry, but I tried both

With a surface it says ? no matching function call ?, it doesn?t 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);

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
