Screensavers for Flux

I’m working on creating native screensavers for Flux — a fluid simulation inspired by the macOS Drift screensaver.

This repository contains:

• flux-ffi — a foreign function interface for the Flux library.
• Native screensavers for the following platforms:
  • MacOS
  • Windows
  • Linux

Build

macOS

Build with XCode.

cd macos
xcodebuild -project Flux.xcodeproj/ -scheme Flux build

XCode should automatically build the FFI crate. In case it doesn’t, here’s how to do it manually.

cd flux-ffi
export MACOSX_DEPLOYMENT_TARGET=10.10
cargo build --release --target aarch64-apple-darwin
cargo build --release --target x86_64-apple-darwin
lipo target/aarch64-apple-darwin/release/libflux.a target/x86_64-apple-darwin/release/libflux.a -create -output libflux.a

Windows

This repo is set up to cross-compile Windows binaries from Linux using Nix.

nix build ./#flux-screensaver-windows

There’s also a cross-compilation development shell.

nix develop ./#cross-windows
cd windows
cargo build --target x86_64-pc-windows-gnu --release

Native Windows builds are currently untested. You’ll need Rust and a static build of SDL2 linked at build time.
