SDL2_image on A1222
Just popping in
Just popping in


See User information
Hello

Having always been on Amiga Classic, I finally took the Amiga-NG step by getting an A1222 (I am a AOS4.1 beginner)

Wanting to take advantage of the power of this one, I would like to develop in SDL2 on it and I must admit that I am having a little trouble setting this up (this is different from Windows).
I'm currently stuck with SDL Image

For information :
- I use Cubic IDE for dev
- I installed sdk 54.16
- I use GCC 4.2.4
- I installed SDL2
- I also installed libSDL2_image, libSDL2_ttf, libjpeg, libwebp, libiff, libsmpeg2, libsdl2_net, libsdl2_mixer, libsdl2_gfx each time using the Autoinstall

It works correctly to compile in C and SDL2, but error for the SDL_image

Here is my code (which works on windows)

#include 
#include 
#include 
#include 

#define SDL_ASSERT_LEVEL 2

int test 1;

SDL_Texture *LoadTexture(SDL_Renderer *rendererchar *path)
{
    
SDL_Texture *texture NULL;

    
texture IMG_LoadTexture(rendererpath);
    if (
texture == NULL)
    {
        
printf("Unable to create texture from %s! SDL Error: %s\n"pathSDL_GetError());
        return 
NULL;
    }

    return 
texture;
}

libSDL2_image has a few dependencies that have to be linked against, too. You seem to be missing libtiff and the libwebp libraries.

The problem is that they are well installed.

I used autoinstall and they are well in SDK:local

so I don't understand why it doesn't work

path of such files (.a/.so)?

I use this on my makefile:
CXXLIB = -LSDK:SDK:local/newlib/lib/

LFLAGS = $(CXXLIB) -lSDL2_image -ltiff -lwebp -lwebpdemux -lsharpyuv -lpng16 -ljpeg -lSDL2 -lz -lpthread -athread=native


being SDK:SDK:local/newlib/lib/ my path to the SDL2 and SDL_image .a/.so files (and its dependencies)

GCC 4.x is not part of the SDK 54.16? How did you install it and why you prefer to use that old version? Is there some kind of a benefit using it?

gcc on amiga is not very smart when it comes to finding (perfectly) installed deps.

just like the others have written, you need to write out every dependant library in the linker line, otherwise it will always error.

Also order is important, if something complains, just shuffle the deps around, tedious and annoying, but ... well, amiga

Yes, but your makefile doesn't seem to include the relevant linking flags...

could you please share an entire makefile?

GCC 4.2.4 was installed by default (maybe with Cubic), is there a more recent version?

Absolutely! The latest SDK gives you GCC 6, 8, 10 and 11. You should use at least GCC 8, unless you need to compile for the A1222's SPE, in which case you'll need GCC 6 (because SPE support was dropped in later versions).

Yeah, CubicIDE has an old version. I do not let the plugin do the SDK installation.
SDK has multiple different versions which you can select with its installer. There is GCC 8, 10, 11 and 6 for SPE compatibility (A1222).

I am using gcc v.6 for SPE programming.
Please, are there any reason to use v.8 or v.10 for standard powerpc codes?
Had they some advantage / feature over v.11 ?
