Spacedrive native dependencies

Build instructions

To build the native dependencies a docker or podman installation is required. It is recomended to enable BuildKit in docker.

Just run the following inside this directory:

$> docker build --build-arg TARGET=<TARGET> -o . .

or

$> podman build --jobs 4 --format docker --build-arg TARGET=<TARGET> -o . .

Where <TARGET> is one of:

• x86_64-darwin-apple
• aarch64-darwin-apple
• x86_64-windows-gnu
• aarch64-windows-gnu
• x86_64-linux-gnu
• aarch64-linux-gnu
• x86_64-linux-musl
• aarch64-linux-musl
• x86_64-linux-android
• aarch64-linux-android

To build for iOS choose one of the darwin targets and pass --build-arg OS_IPHONE=<1|2> as an argument, 1 means iOS and 2 means iOS Simulator. Only iOS simulator supports x86_64.

After some time (it takes aroung 1~2 hours in Github CI) a directory named out will show up in the current directory containing our native dependencies.

TODO (Order of importance)

• Fortify linux-musl shared libs:

  https://git.2f30.org/fortify-headers/file/README.html

• Add stack check to windows dlls whenever zig adds support to it:

  https://github.com/ziglang/zig/blob/b3462b7/src/target.zig#L326-L329

• Add stack check/protector to linux arm64 shared libs whenever zig fix the bug preventing it from working:

  ziglang/zig#17430 (comment)

• Add support for pthread in windows builds:

  https://github.com/GerHobbelt/pthread-win32 https://sourceforge.net/p/mingw-w64/mingw-w64/ci/master/tree/mingw-w64-libraries/winpthreads/ https://github.com/msys2/MINGW-packages/blob/f4bd368/mingw-w64-winpthreads-git/PKGBUILD

• Add libplacebo and vulkan support for apple builds through MoltenVK:

  https://github.com/KhronosGroup/MoltenVK

• Add Metal shader support for ffmpeg in apple builds:

  darlinghq/darling#326

• Investigate why LTO fails at linking ffmpeg's libav* libs for windows builds
• Investigate why LTO fails when linking any static lib in apple builds:

  tpoechtrager/osxcross#366

Acknowledgments

This build system is losely base on:

• https://github.com/BtbN/FFmpeg-Builds

It uses Zig 0.12 as a C/C++ toolchain to build the Windows and Linux targets:

• https://github.com/ziglang/zig/tree/0.11.0

It uses LLVM/Clang 17 with some tweaks from osxcross + Apple's cctools and linker to build the Darwin (macOS, iOS) targets:

• https://github.com/llvm/llvm-project/tree/llvmorg-17.0.6
• https://github.com/tpoechtrager/osxcross
• https://github.com/tpoechtrager/cctools-port

By building the Darwin target you are agreeing with the Apple Public Source License (APSL) and the Xcode license terms

Thanks to all the developers involved in making the dependencies used by this project
