Compilation targets

Native binaries, cross-compilation, and WebAssembly.

Native (default)

clang + the Nyra runtime — full stdlib, timing, memory, channels.

Cross-compilation

Build a release binary for another OS while developing on macOS, Linux, or Windows:

nyra build . --release --for windows
nyra build . --release --for linux
nyra build . --release --for macos
nyra build . --release --os linux --arch aarch64

Advanced: full LLVM triple with --target x86_64-unknown-linux-gnu (overrides --for).

Cross artifacts: target/<triple>/release/main (adds .exe on Windows). nyra run cannot execute foreign binaries.

From → To	Toolchain notes
macOS → Linux	Cross GCC toolchain + clang (e.g. `brew install messense/macos-cross-toolchains/aarch64-unknown-linux-gnu`)
macOS / Linux → Windows	MinGW-w64 + clang; Windows target uses `*-pc-windows-gnu` (not MSVC cross)
Linux / Windows → macOS	Requires osxcross + Apple SDK (advanced)
Any → Wasm	LLVM clang with `wasm32-wasi` (Apple clang lacks this — use Homebrew `llvm`)

Optional: set NYRA_SYSROOT or pass --link-arg for custom sysroots.

Windows cross-compile (--for windows, MinGW *-pc-windows-gnu): hello, print, file I/O, spawn (Win32 threads), TCP/HTTP (Winsock2), and async/await (Win32 sync + select socket I/O). Run the resulting .exe on Windows or Wine. Bridge subprocess (bridge_exec) remains POSIX-only.

wasm32-wasi

nyra build --for wasm app.ny -o app.wasm
nyra build --target wasm32-wasi app.ny -o app.wasm

Timing/memory no-ops; spawn limited.
