安装Dlib时无法找到Boost

Question

我是一个Windows用户，目前正在使用Windows 10.我试图在过去8小时的python 3.5上安装Dlib，但是失败了。每当我尝试“点安装Dlib”，或尝试“python setup.py install”（在dlib文件夹中），我会收到错误消息，说“cmake配置失败”。在整个执行过程中，我可以看到“无法找到BOOST”。有人可以在这里指导我吗？

If you installed boost and you are still getting this error then you might have installed a version of boost that was compiled with a different version of visual studio than the one you are using.

Answer 1

尝试以下步骤：（调整适用于Windows）

1. 下载升压源码包。

2. cd为抽出升压文件夹

3. 运行.\bootstrap.bat

4. 运行.\b2 runtime-link=shared link=shared。 （这将创建一个被自己链接到动态运行时库动态升压库

5. 设置以下环境变量（它们调整到自己的道路路径）后：

   BOOST_LIBRARYDIR="C:\Developer\boost_1_62_0\stage\lib" 
   

   BOOST_INCLUDEDIR="C:\Developer\boost_1_62_0" 
   

   BOOST_ROOT="C:\Developer\boost_1_62_0" 
   

6. 重试与python setup.py install

我有一个类似的问题时的CMake的find_package()找不到提振，原因是建设升压只有b2，没有参数link=shared导致产生.lib文件有一个前缀在Windows“LIB”而CMake的find_package()并不认为这些库有“lib”前缀。
