macOS Build

Tested on macOS 10.15.7, Xcode 12.4, x86_64.

  1. Prerequisites:

    • vcpkg requires brew install pkg-config

  2. Run setup-vcpkg.sh (fetches + builds vorbis, opus, zlib from vcpkg, as static libraries.)

    The Opus .dylibs included with QuakeSpasm lack the encoder, which is needed by snd_voip.c, necessitating building it from source.

  3. For a release build, run xcodebuild -project QuakeSpasm.xcodeproj -target QuakeSpasm-Spiked-SDL2

Limitations

  • SDL 1.2 is no longer supported
    • Some code assumes SDL 2.0+ (e.g. VID_UpdateCursor)
  • Only x86_64 is currently supported
    • arm64 should be possible in theory, just needs someone with an M1 mac to implement and test it.
  • Minimum macOS version raised to 10.9; PowerPC and i386 dropped
    • This is the lowest version I can target with macOS 10.15.7, Xcode 12.4
