From 83e86745ae059aae11b03b6a53c382f8e68b94c6 Mon Sep 17 00:00:00 2001 From: LiHaohua Date: Wed, 3 Jun 2026 13:57:18 +0800 Subject: [PATCH] macOS: static-link deps, drop SDL2_image, ad-hoc sign, ship zip + dmg MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Kills the Gatekeeper 'Apple cannot verify libSDL2_image…' prompt that fired once per bundled dylib (22 times) on first launch of a downloaded macOS build. Root cause: the bundle shipped 22 third-party dylibs (SDL2_image and its whole avif/jxl/webp/tiff/lcms/… transitive tree), none signed/notarized, each quarantined. Changes: - src/png_to_sdl_surface.{c,h}: load PNG via LVGL's bundled lodepng instead of SDL2_image. The emulator only ever loaded one PNG (the device skin) and only IMG_INIT_PNG, so SDL2_image was pure overhead. APPLaunch icons already decode through LVGL's LV_USE_LODEPNG, untouched. - src/main.cpp / main_web.cpp: use load_png_as_sdl_surface(), drop SDL_image. - CMakeLists.txt: remove SDL2_image entirely. Add EMU_MACOS_STATIC_DEPS=ON (default) — statically link libSDL2.a + libfreetype.a + libpng16.a with the Cocoa/CoreAudio/etc frameworks SDL2 needs. Result: cardputer-emu has zero third-party dylib references (verified via otool -L in CI). - build.yml macos job: install sdl2/freetype/libpng (no sdl2_image), build static, ad-hoc codesign every Mach-O (cardputer-emu + our two app dylibs), strip the quarantine xattr, and produce BOTH a green zip and a DMG. Bundle size dropped ~40% (10.8MB → 6.2MB). Windows / Linux / Web unchanged. --- .github/workflows/build.yml | 77 +++++++++++++++++--------- CMakeLists.txt | 104 +++++++++++++++++++++++------------- src/main.cpp | 8 ++- src/main_web.cpp | 7 ++- src/png_to_sdl_surface.c | 45 ++++++++++++++++ src/png_to_sdl_surface.h | 23 ++++++++ 6 files changed, 192 insertions(+), 72 deletions(-) create mode 100644 src/png_to_sdl_surface.c create mode 100644 src/png_to_sdl_surface.h diff --git a/.github/workflows/build.yml b/.github/workflows/build.yml index 3d2d7a6..d01cb0e 100644 --- a/.github/workflows/build.yml +++ b/.github/workflows/build.yml @@ -9,13 +9,16 @@ on: jobs: # ── macOS arm64 + x64 (matrix) ────────────────────────────────────────────── - # ── macOS arm64 ───────────────────────────────────────────────────────────── - # We ship arm64 only on macOS.
