SDL: migrate to SDL3 via sdl2-compat and add SDL3 Doom#140
Merged
Conversation
Core Simple DirectMedia Layer 3 library, the base for the SDL2 to SDL3 transition. CMake build with the same backend selection as the SDL2 package (KMSDRM, Wayland, Vulkan, OpenGL/ES, ALSA and PulseAudio with dlopen, HIDAPI, dummy video/audio; X11 and dbus off). Provides libSDL3.so and the SDL3 development files, plus a libsdl3-tests package with the upstream installed-tests (SDL_INSTALL_TESTS). https://github.com/libsdl-org/SDL/releases/tag/release-3.4.10 Signed-off-by: Daniel Golle <daniel@makrotopia.org>
The SDL2 library is now provided by the sdl2-compat package built on top of SDL3, so the standalone SDL2 2.32.x package is no longer needed. Signed-off-by: Daniel Golle <daniel@makrotopia.org>
sdl2-compat implements the SDL2 API on top of SDL3, shipping the libSDL2-2.0 shared library and SDL2 development files. The package is named libsdl2-compat and only PROVIDES libsdl2, so existing SDL2 consumers resolve to it without a package name collision while the single SDL3 build backs both APIs. https://github.com/libsdl-org/sdl2-compat/releases/tag/release-2.32.70 Signed-off-by: Daniel Golle <daniel@makrotopia.org>
Stay on the SDL2 line (libSDL2_mixer), now built against the sdl2-compat layer. 2.8.2 is the current latest SDL2-targeting SDL_mixer release; the SDL3-native line is packaged separately as sdl3-mixer. https://github.com/libsdl-org/SDL_mixer/releases/tag/release-2.8.2 Signed-off-by: Daniel Golle <daniel@makrotopia.org>
SDL3-native image loading library (libSDL3_image), built directly against SDL3 so it coexists with sdl2-image's libSDL2_image. PNG, JPEG, TIFF and WebP are handled by the libpng, libjpeg, libtiff and libwebp packages, listed as dependencies so the cross-built target libraries are used instead of host libraries; the bundled stb backend is disabled. https://github.com/libsdl-org/SDL_image/releases/tag/release-3.4.4 Signed-off-by: Daniel Golle <daniel@makrotopia.org>
Build PNG, JPEG, TIFF and WebP support against the libpng, libjpeg, libtiff and libwebp packages rather than the bundled stb_image backend. Listing them as dependencies ensures the cross-built target libraries are picked up instead of host libraries. Signed-off-by: Daniel Golle <daniel@makrotopia.org>
SDL3-native audio mixer library (libSDL3_mixer), built directly against SDL3 so it coexists with sdl2-mixer's libSDL2_mixer. MIDI, Opus, WavPack and MOD support via libfluidsynth, libopusfile, libwavpack and libxmp. https://github.com/libsdl-org/SDL_mixer/releases/tag/release-3.2.4 Signed-off-by: Daniel Golle <daniel@makrotopia.org>

A source port of DOOM to SDL3 (raydelto/sdl3_doom), the first real SDL3 application in the feed, replacing the orphaned sdl2-doom. It builds against libsdl3 and libsdl3-mixer and plays authentic OPL FM music from the IWAD's GENMIDI lump, needing no soundfont. The upstream port targets an early SDL3_mixer prerelease (Mix_* API, removed in SDL_mixer 3.2.0) and had dropped the OPL music backend. Carry nine patches: port both audio backends to the track-based MIX_* API, share a single mixer device, link the exported SDL3 CMake targets, build the sound-effect module (FEATURE_SOUND), restore the Chocolate DOOM OPL backend for native FM music, fix a pre-existing status-bar crash and drop the stale SDL2_mixer cmake module. These are also suitable to submit upstream. https://github.com/raydelto/sdl3_doom Signed-off-by: Daniel Golle <daniel@makrotopia.org>
The orphaned sdl2-doom port is superseded by sdl3-doom, which targets SDL3 directly. Signed-off-by: Daniel Golle <daniel@makrotopia.org>

Description:
Migrate the SDL stack from SDL2 to SDL3 while keeping existing SDL2 consumers building:
libsdl2-compat, onlyPROVIDES libsdl2) on top of SDL3 and drop the standalone sdl2 package, so SDL2 consumers resolve to the compat layerThe sdl3-doom port carries nine patches porting both audio backends to the SDL3_mixer 3.2
MIX_*API, sharing a single mixer device, building the sound-effect module, restoring the Chocolate DOOM OPL backend for authentic FM music (no soundfont needed) and fixing a status-bar crash. These are suitable to submit upstream.🧪 Run Testing Details
sdl3 and sdl3-doom were run-tested on x86_64 (Arch Linux build host): SDL3 Doom runs and plays with authentic OPL FM music and sound effects. The remaining packages in this PR are compile-tested only on
mediatek/filogic(aarch64_cortex-a53).✅ Formalities
