Frame Studio now builds for Windows (x64, x86, ARM64), Linux (x64, x86, ARM64)
and macOS (Apple Silicon, Intel):
- studio/platform.h with Win32 and POSIX implementations (dialogs through
tinyfiledialogs on Linux/macOS), a GLFW window beside the Win32 one, and a
platform-neutral frame pacer
- MoltenVK support in the renderer (portability enumeration) and bundled in
the macOS app
- 32-bit builds: large-address-aware, LZMA packing within a 32-bit address space
- unaligned file reads in the loaders go through loadUnaligned (no UB)
- scripts/build-studio.sh, studio/build_windows.bat [x64|x86|arm64],
cmake/llvm-mingw.cmake, and a GitHub Actions workflow building every target
Frame Home installs without Studio: frame/install-frame-home.{sh,ps1} and
"Install Frame Home.bat" (packaged as FrameHome-installer.zip).
