+== Compile go program with static compile flag (take 2) ==
+Linking against glibc.static does not really work because glibc does not really like static linking. You get a warning like <code>warning: Using 'getaddrinfo' in statically linked applications requires at runtime the shared libraries from the glibc version used for linking</code>. To really create a static build, use musl. Example based on buildGoModule example from documentation:
+<syntaxHighlight lang=nix>
+pet = buildGoModule rec {
+  pname = "pet";
+  version = "0.3.4";
+  src = fetchFromGitHub {
+    owner = "knqyf263";

+    rev = "v${version}";
