Homebrew 包之间缺少 link

Question

我在 MacOS 10.12 Sierra 上通过 brew 安装了 boost 和 boost-python。但是，boost-python 似乎并不认为其依赖项 boost 已安装：

$ brew info boost
boost: stable 1.68.0 (bottled), HEAD
Collection of portable C++ source libraries

Building of Boost.Log is disabled because it requires newer GCC or Clang.

如何让 boost-python 识别 / link 及其依赖项 boost 的存在？

如果我能避免卸载和重新安装就太好了，因为有太多其他依赖于 boost 的包让我花了 long/difficult 时间才开始工作。

我这样做是因为：编译 caffe 时，它说 ld: library not found for -lboost_python。谢谢。

Answer 1

这就是我设法让 boost-python 识别其依赖项 booth 的存在的方法。 在不卸载 Homebrew 中任何现有的 boost 和 boost-python 软件包的情况下，我运行以下行

brew install --build-from-source -vd boost boost-python

这似乎重新安装了两个软件包并清楚地建立了 link。

为了解决 Caffe 编译问题，此命令在 /usr/local/lib 中生成文件 libboost_python27* 个文件，我刚刚将其复制并重命名为 libboost_python*。
