## Build a native macOS release binary.
## The frontend is compiled by build.rs (pnpm build) and embedded via rust-embed.
## Verify dynamic deps afterwards: otool -L target/release/story-kit-server
build-macos:
	cargo build --release

## Build a fully static Linux x86_64 binary using the musl libc target.
## cross (https://github.com/cross-rs/cross) handles the Docker-based cross-compilation.
## Install cross:  cargo install cross
## The resulting binary has zero dynamic library dependencies (ldd reports "not a dynamic executable").
build-linux:
	cross build --release --target x86_64-unknown-linux-musl
