在 mac OS X 上安装 big float

Question

我正在尝试在 OS X 上安装 big float，但我遇到了多个问题。我安装 amp 没有任何问题，但是当我尝试安装 mpfr 时出现此错误：

Warning: mpfr-3.1.5 already installed, it's just not linked.

这是什么意思？（我正在使用自制软件）。

然后，很明显，如果我尝试安装 bigfloat，它不起作用，我收到此错误：

您必须安装 python-devel

在OSX中尝试卸载再安装：

brew uninstall python
brew install python

此外，根据 this 问题，Osx GCC（这只是 clang 的符号链接）不附带 OpenMP 开箱即用的支持。您可以安装 GCC 和 OpenMP。

brew install gcc --without-multilib
