If you intend to compile against glibc statically (such as via <tt>go build -ldflags "-s -w -linkmode external -extldflags -static"</tt>), add <tt>glibc.static</tt> to the list of packages passed to <tt>nix-shell</tt>. | If you intend to compile against glibc statically (such as via <tt>go build -ldflags "-s -w -linkmode external -extldflags -static"</tt>), add <tt>glibc.static</tt> to the list of packages passed to <tt>nix-shell</tt>. | ||

If <code>go build -ldflags "-s -w -linkmode external -extldflags -static"</code> fails on NixOS, with the error message <code>cannot find `-lpthread</code> and <code>cannot find -lc</code> - 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: | |||
<syntaxHighlight lang=nix> | |||
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"; | |||
}; | |||
} | |||
</syntaxHighlight> | |||
