红宝石与tk的支持

Question

我正在跟踪一个ruby，该programming languages course需要tk支持。我的笔记本电脑运行nixos。只需将tk和ruby添加到我的系统软件包中就不会削减它。两者都不能创建nix-shell。在tk支持下编译ruby时，我该如何构造一个推导？

shell.nix

{ pkgs ? import <nixpkgs> {} }:

with pkgs;

let
  myRuby = ruby_2_3.overrideAttrs (old: {
    configureFlags = [
      "--with-tcl-dir=${tcl}"
      "--with-tk-dir=${tk}"
      "--enable-tcl-thread"
      "--enable-pthread"
    ];
    buildInputs = [
      ruby_2_3
      zlib
      gdbm
      libffi
      openssl
      readline
    ];
    propagatedBuildInputs = [
      tk
      tcl
    ];

  });

in
  mkShell {
    buildInputs = [ myRuby tk tcl ];
  }

test.rb

#!/usr/bin/env ruby
 require 'tk'
 root = TkRoot.new do
   title "Ruby/Tk Test"
 end
 Tk.mainloop

我决定只构建一个衍生版本并安装它。可行！

{ pkgs ? import <nixpkgs> {} }:

with pkgs;

let
  myRuby = ruby_2_3.overrideAttrs (old: {
    configureFlags = [
      "--with-tcl-dir=${tcl}"
      "--with-tk-dir=${tk}"
      "--enable-tcl-thread"
      "--enable-pthread"
    ];
    buildInputs = [
      ruby_2_3
      zlib
      gdbm
      libffi
      openssl
      readline
    ];
    propagatedBuildInputs = [
      tk
      tcl
    ];

  });

in
  myRuby
