python - 在 os x 上编译 dlib 时出错

Question

我正在尝试在我的计算机 (OS X 10.10) 上编译 dlib，但遇到错误我不确定如何修复。当我运行 CMake 时，我得到了这个输出

Configuring cmake ...

首先，我想知道 CMake 是如何找不到 Boost 的，但在下一行给出了我目前在我的计算机上安装的 boost 版本？其次，我想知道如何修复 pythonlibs 错误？我试过谷歌搜索，但主要只是发现其他人有类似的错误，但不知道它的含义或如何修复它。任何帮助将不胜感激。谢谢

Answer 1

你的 boost 是用 python 3 安装的吗？如果是这样，我建议你设置默认的 python 版本 3.x，或者像这样用当前的 python 版本重新安装 boost:

To compile Boost.Python yourself download boost from boost.org and then go into the boost root folder and run these commands:
./bootstrap.sh --with-libraries=python
./b2
sudo ./b2 install

我已经用上述解决方案解决了Could NOT find Boost的问题。
