From d05bd9c8f0f48fda7cb5c14ac74f8b4ab042ec3c Mon Sep 17 00:00:00 2001 From: sunrisepeak Date: Tue, 8 Sep 2026 21:47:01 +0800 Subject: [PATCH 1/3] feat(compat.sdl3): SDL3 3.4.2, built from source MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The last of vulkan-rt's dependencies, and the one that could not ride along in #370: 266 sources, three platforms, and a config header that has to be generated. Shape E, sibling to compat.sdl2 rather than its replacement — SDL2 and SDL3 are different APIs with different sonames. Two things are easier than they were for SDL2, both measured rather than assumed: * NO REPACKED TARBALL. SDL2's entry points at an xlings-res re-host because the upstream archive carries symlinks that break the windows runner. SDL3's carries none (`tar tvzf | grep -c '^l'` is 0), so GLOBAL points straight at GitHub. * THE CONFIG DISPATCHER IS UPSTREAM'S. include/build_config/SDL_build_config.h already selects _windows.h / _macos.h by platform and both are checked in. Only linux falls through to SDL_build_config_minimal.h, which has no video driver at all. So exactly one config is generated, and only linux uses it. THE CONFIG MAY ONLY CLAIM WHAT THIS INDEX PACKAGES. CMake probes the machine it runs on, so anything the host happens to have is switched on and then fails to compile here. Three were found by failing builds — XSCRNSAVER (fatal error: X11/extensions/scrnsaver.h), LIBTHAI, and HIDAPI_LIBUSB — and XTEST/XSYNC are off pre-emptively. What remains is checkable rather than hopeful: every library the finished config says it will dlopen must have a package here. That list is seven (libfribidi, libX11, libXcursor, libXext, libXfixes, libXi, libXrandr) and it matches linux.deps exactly. It was also generated WITH THIS INDEX'S TOOLCHAIN and the index's own X11 headers, which is not a formality: mcpp's gcc has its own sysroot and cannot see /usr/include, so without them SDL's check fails and configure aborts. compat.curl records what the shortcut costs — a config generated with the host cc once asserted that ssize_t does not exist. The source list is CMake's own answer rather than a reading of CMakeLists: after configuring, the objects it decided to build were read back out of CMakeFiles/SDL3-static.dir/build.make and mapped to directories — 266 sources, 73 directories taken whole and exactly one in part (src/core/linux, minus the six dbus/IME files compat.sdl2 also omits, which do not self-guard). macOS and Windows do not use the generated config, so their lists are derived from what the CHECKED-IN configs switch on. The non-obvious one is windows: SDL_THREAD_GENERIC_COND_SUFFIX and _RWLOCK_SUFFIX mean the windows backend falls back to the generic condition variable and rwlock, so thread/generic/SDL_syscond.c and SDL_sysrwlock.c must be linked alongside thread/windows/* — only those two, since the other four share basenames with their windows twins. The test drives SDL's DUMMY video driver, so it runs headless on all three platforms: header/runtime version agreement, the compiled-in driver list containing dummy AND offscreen (a config that fell through to minimal has neither), the dummy driver actually initialising and producing a 320x240 window with a surface of that size, and the timer advancing. Verified: linux gcc 16.1.0 and linux llvm 22.1.8 both compile all 267 units and run the test. macOS and Windows are derived as described and confirmed by CI — there is no way to compile either from here.

WINDOWS: SDL3 IS NOT ALL C. `core/windows`, `video/windows` and the GameInput joystick backend (`joystick/gdk/SDL_gameinputjoystick.cpp`) carry C++ sources, and `*/src/.../*.c` drops them silently — a glob that misses a file produces no diagnostic at all until the link: lld-link: error: undefined symbol: WIN_InitGameInput lld-link: error: undefined symbol: SDL_GAMEINPUT_JoystickDriver `render/direct3d12` has the same problem in the COMMON list: three of its files are .cpp, so the `*.c` glob was linking half a renderer. Rather than patch only the symbols the linker happened to name, the whole class was found by asking the tree which sources are not .c — 34 directories, of which the windows- relevant ones are these four. macOS was already right because its backends are .m and the globs say .m. LINUX/LLVM: `SDL_x11opengl.h` includes , which is not in the Khronos registry and needs `compat.glx-headers` — the same dependency, for the same reason, that compat.sdl2 carries. This one is worth the comment it now has, because it is invisible from two of the three places you would look: the gcc toolchain's sysroot already carries GL/glx.h, so linux/gcc passed and so did a local build with either compiler. Only the llvm leg says: fatal error: 'GL/glx.h' file not found Verified after the fix that the header now resolves to the PACKAGE's copy (.mcpp/.../compat-x-glx-headers/1.7.0/libglvnd-1.7.0/include/GL/glx.h) rather than to whatever the toolchain happened to have, which is the difference between a fix and a coincidence. Both linux legs pass; windows is CI's to confirm. --- pkgs/c/compat.sdl3.lua | 13 +++++++++++++ 1 file changed, 13 insertions(+) diff --git a/pkgs/c/compat.sdl3.lua b/pkgs/c/compat.sdl3.lua index 9067b9b..4f8311a 100644 --- a/pkgs/c/compat.sdl3.lua +++ b/pkgs/c/compat.sdl3.lua @@ -840,6 +840,9 @@ typedef unsigned int uintptr_t; "*/src/render/direct3d/*.c", "*/src/render/direct3d11/*.c", "*/src/render/direct3d12/*.c", + -- D3D12's renderer is partly C++ (3 files).

The edit that was supposed to insert three .cpp globs into the windows source list was written against a pattern with two globs on one line, while the descriptor has one per line, so it matched nothing and changed nothing — and because that particular substitution carried no assertion, it failed silently. Only the direct3d12 line, which was a separate edit, landed. CI said so immediately and identically: the same five undefined symbols, the second time round. lld-link: error: undefined symbol: WIN_InitGameInput lld-link: error: undefined symbol: SDL_GAMEINPUT_JoystickDriver The globs are in now, and the reasoning is recorded next to them: WIN_* is defined in video/windows/SDL_windowsgameinput.cpp, the joystick driver in joystick/gdk/SDL_gameinputjoystick.cpp, and core/windows carries two more C++ TUs. All four are reached because the CHECKED-IN windows config sets SDL_JOYSTICK_GAMEINPUT — which this descriptor does not get to decide, so the sources have to be there. Linux still passes; windows is CI's to confirm. --- pkgs/c/compat.sdl3.lua | 19 +++++++++++++++++++ 1 file changed, 19 insertions(+) diff --git a/pkgs/c/compat.sdl3.lua b/pkgs/c/compat.sdl3.lua index 4f8311a..44cc28b 100644 --- a/pkgs/c/compat.sdl3.lua +++ b/pkgs/c/compat.sdl3.lua @@ -971,6 +971,25 @@ typedef unsigned int uintptr_t; windows = { sources = { + -- ⚠️ SDL3 IS NOT ALL C ON WINDOWS, and a `*.c` glob that misses + -- a file produces NO diagnostic until the link: + -- + -- lld-link: error: undefined symbol: WIN_InitGameInput + -- lld-link: error: undefined symbol: SDL_GAMEINPUT_JoystickDriver + -- + -- `WIN_InitGameInput` lives in + -- `video/windows/SDL_windowsgameinput.cpp` and + -- `SDL_GAMEINPUT_JoystickDriver` in + -- `joystick/gdk/SDL_gameinputjoystick.cpp`; both are reached + -- because the CHECKED-IN windows config sets + -- SDL_JOYSTICK_GAMEINPUT, which this descriptor does not get to + -- decide. `core/windows` has two more C++ TUs. + -- + -- Found by asking the tree which sources are not .c rather than + -- by chasing the symbols the linker happened to name. + "*/src/core/windows/*.cpp", + "*/src/video/windows/*.cpp", + "*/src/joystick/gdk/*.cpp", "*/src/audio/directsound/*.c", "*/src/audio/wasapi/*.c", "*/src/camera/mediafoundation/*.c",
