我一直在尝试将Ejabberd嵌入到Phoenix网络应用程序中。为此,我尝试关注this tutorial。步骤如下:

  • 安装了ubuntu/xenial64 Vagrant框。

  • 根据official guide安装了Elixir。

  • 根据official guide安装凤凰。

  • 安装了一些软件包以成功编译Phoenix的种子应用程序依赖项:sudo apt install build-essential libssl-dev libyaml-cpp-dev libyaml-dev libpython2.7-dev

  • 我已将ejabberd依赖项添加到mix.exs文件中:

    defmodule PhoenixEjabberd.Mixfile do
      use Mix.Project
    
      def project do
        [app: :phoenix_ejabberd,
         version: "0.0.1",
         elixir: "~> 1.2",
         elixirc_paths: elixirc_paths(Mix.env),
         compilers: [:phoenix, :gettext] ++ Mix.compilers,
         build_embedded: Mix.env == :prod,
         start_permanent: Mix.env == :prod,
         aliases: aliases(),
         deps: deps()]
      end
    
      # Configuration for the OTP application.
      #
      # Type `mix help compile.app` for more information.
      def application do
        [mod: {PhoenixEjabberd, []},
         applications: [:phoenix, :phoenix_pubsub, :phoenix_html, :cowboy, 
                        :logger, :ejabberd, :gettext,
                        :phoenix_ecto, :postgrex]]
      end
    
      # Specifies which paths to compile per environment.
      defp elixirc_paths(:test), do: ["lib", "web", "test/support"]
      defp elixirc_paths(_),     do: ["lib", "web"]
    
      # Specifies your project dependencies.
      #
      # Type `mix help deps` for examples and options.
      defp deps do
        [{:phoenix, "~> 1.2.1"},
         {:phoenix_pubsub, "~> 1.0"},
         {:phoenix_ecto, "~> 3.0"},
         {:postgrex, ">= 0.0.0"},
         {:phoenix_html, "~> 2.6"},
         {:phoenix_live_reload, "~> 1.0", only: :dev},
         {:gettext, "~> 0.11"},
         {:cowboy, "~> 1.0"},
         {:ejabberd, "~> 16.12", github: "processone/ejabberd"}
       ]
      end
    
      # Aliases are shortcuts or tasks specific to the current project.
      # For example, to create, migrate and run the seeds file at once:
      #
      #     $ mix ecto.setup
      #
      # See the documentation for `Mix` for more info on aliases.
      defp aliases do
        ["ecto.setup": ["ecto.create", "ecto.migrate", "run priv/repo/seeds.exs"],
         "ecto.reset": ["ecto.drop", "ecto.setup"],
         "test": ["ecto.create --quiet", "ecto.migrate", "test"]]
      end
    end
    
  • 已执行mix do deps.get, compile

  • 出现了大量错误,主要是未定义的函数和变量。我将完整的日志记录在this Gist

为什么会出现这些错误?有没有人成功编译ejabberd依赖?怎么样?谢谢您的时间:)。

答案 0 :(得分:1)

由于未知原因,ejabberd无法从根项目文件夹进行编译。为了编译它,我做了以下几点:

mix deps.get # to retrieve ejabberd 
cd deps/ejabberd
mix do deps.get, compile
cd - # to the project root
mix compile # now the project would compile
