Go is a statically-typed language with syntax loosely derived from that of C, adding garbage collected memory management, type safety, some dynamic-typing capabilities, additional built-in types such as variable-length arrays and key-value maps, and a large standard library.

Compile go program with static compile flags

If go build -ldflags "-s -w -linkmode external -extldflags -static" fails on NixOS, with the error message cannot find-lpthreadandcannot find -lc` - it is because the linker cannot find static glibc to link with. You need to have glibc.static in your environment (and have CFLAGS/LDFLAGS adjusted accordingly).

One way to achieve this is to have something like the following as shell.nix and run the compilation in a nix-shell:

with import <nixpkgs> {}; {
  devEnv = stdenv.mkDerivation {
    name = "dev";
    buildInputs = [ stdenv git go glibc.static ];
    CFLAGS="-I${pkgs.glibc.dev}/include";
    LDFLAGS="-L${pkgs.glibc}/lib";
  };
}
