NAME¶

SDL_ELF_NOTE_DLOPEN - Note that your application has dynamic shared library dependencies.

SYNOPSIS¶

#include <SDL3/SDL_dlopennote.h>

#define SDL_ELF_NOTE_DLOPEN(feature, description, priority, ...) \
    SDL_ELF_NOTE_INTERNAL(                                       \
        "[{\"feature\":\"" feature                               \
        "\",\"description\":\"" description                      \
        "\",\"priority\":\"" priority                            \
        "\",\"soname\":" SDL_SONAME_ARRAY(__VA_ARGS__) "}]",     \
        SDL_ELF_NOTE_UNIQUE_NAME)

DESCRIPTION¶

You can do this by adding the following to the global scope:

SDL_ELF_NOTE_DLOPEN(


    "png",


    "Support for loading PNG images using libpng (required for APNG)",


    SDL_ELF_NOTE_DLOPEN_PRIORITY_RECOMMENDED,


    "libpng12.so.0"
);
    

Or if you support multiple versions of a library, you can list them:

// Our app supports SDL1, SDL2, and SDL3 by dynamically loading them
SDL_ELF_NOTE_DLOPEN(


    "SDL",


    "Create windows through SDL video backend",


    SDL_ELF_NOTE_DLOPEN_PRIORITY_REQUIRED


    "libSDL-1.2.so.0", "libSDL2-2.0.so.0", "libSDL3.so.0"
);
    

AVAILABILITY¶

This macro is available since SDL 3.4.0.
