使用Math :: TrulyRandom模块Dmake文件错误 [英] Dmake file error with Math::TrulyRandom module

问题描述

当我尝试安装 Math :: TrulyRandom时，我听了这个人的意见（一个随机数生成器vs伪随机数），我正在运行'dmake'，他告诉我在另一个问题上询问错误。

I listened to this one person's advice when I tried installing Math::TrulyRandom (A random number generator vs pseudorandom), I was running 'dmake' and he told me to ask about the errors on a different question.

我的第一个问题是这里。

这是终端发生了什么问题：

Here is what went wrong in the terminal:

推荐答案

数学:: TrulyRandom已损坏，不应确实，不能）被使用。

Math::TrulyRandom is broken, and should not (indeed, cannot) be used.

它是在1996年写的，只能在当时存在的某些UNIX系统上正常工作SunOS 4）。它无法在现代Linux系统上生成随机数据，并且无法在Windows上完全编译。

It was written in 1996, and only works correctly on certain UNIX systems which existed at the time (like SunOS 4). It fails to generate random data on modern Linux systems, and cannot be compiled at all on Windows.

如果需要一个随机数生成器，而 rand 不会剪切它，寻找另一个模块。 Math :: Random :: Secure 或 Crypt :: Random ，例如。

If you need a random number generator and rand won't cut it, look for another module. Math::Random::Secure or Crypt::Random, for instance.
