在GuixSystem中配置阴影袜配置文件

Question

我在配置影子袜子配置文件时遇到了这个问题：

解决办法是什么？

有人，他比我写这篇文章时更好地看了源代码，他设计了一块地，并提交给了上游的Guix。换句话说，这个问题可能很快就会得到解决。

看一下“影子袜子”的包定义，它看上去相当空洞，甚至没有将OpenSSL作为输入或任何类似的东西列出。此外，似乎“影子袜子”希望您将所有这些路径保存在某种配置中。

config['crypto_path'] = {'openssl': config['libopenssl'],
                         'mbedtls': config['libmbedtls'],
                         'sodium': config['libsodium']}

这些技巧在传统发行版(如基于Debian等人的发行版)上可能非常聪明，但是当与任何类型的功能包管理一起使用时，它们就彻底崩溃了。处理这类问题的Guix方法是在构建时使用substitute*对输入路径进行硬编码。您的阶段可能如下所示：

  (add-after 'unpack 'patch-crypto-paths
    (lambda* (#:key inputs #:allow-other-keys)
      (substitute* "shadowsocks/shell.py"
        (("config\\['libopenssl'\\]") 
         (string-append (assoc-ref inputs "openssl") "/path/to/libopenssl"))
        [...])
      #t))

由于上面的代码显然是Guix代码，所以您可以在GPLv3+下自由地使用它，即使这样通常也会强制CC SA.

请注意，最近可能不再严格要求以#t结尾，但我认为您仍然可以在Guix代码中找到它。
