Learned a neat #Nix trick: You can easily cross-compile all programs in Nixpkgs (as long as they support the target platform)!

So instead of `nix build nixpkgs#ripgrep`, to build ripgrep for Windows, you can use:

nix build nixpkgs#pkgsCross.mingwW64.ripgrep

Other example targets are:

- "aarch64-multiplatform" (AMD64)
- "gnu32" (i686)
- "riscv64" (64-bit RISC-V)
- "musl64" (x86_64, using musl instead of glibc)

Many more are defined in this file: https://github.com/NixOS/nixpkgs/blob/master/lib/systems/examples.nix

You can also build 32-bit programs more directly:

nix build nixpkgs#pkgsi686Linux.ripgrep

You can also produce a static executable for your current platform:

nix build nixpkgs#pkgsStatic.ripgrep

And best of all – you can combine those! Here's a 32-bit static binary (which happened to be the thing I need right now for my tiny Linux in the browser project):

nix build nixpkgs#pkgsi686Linux.pkgsStatic.ripgrep
