+# Build Scripts

+## Why not just use nix?
+
+It's necessary to produce binaries which are statically-linked with muslc as
+they can be used on all distros of linux (including distros that don't link
+with the gnu linker such as alpine and nixos). While it's possible to also
+produce MacOS binaries with the same nix derivations, we found that aarch64
+binaries for MacOS don't work correctly when built with nix due to [this
+issue](https://discuss.ocaml.org/t/corrupted-compiled-interface-after-dune-build/14919).
