如何构建python C++嵌入的boost示例

Question

我需要包装一个C++库才能在python代码中使用。为此，我似乎最好使用boost python扩展/包装器。但现在，在编译文档中显示的每个示例时，我经常遇到问题。我能够让它运行python27和boost_1_55的组合，但是任何事情(python34，boost_1_58)似乎都不起作用。下面是生成2个基本示例的错误消息(我运行的是windows7 64位)：

我在boost-python教程中也有类似的问题。我认为原因在于我没有python库的调试版本。为了解决这个问题，我将属性variant=release添加到对b2的调用中。这解决了不兼容pdb文件的问题，不过更好的选择是获得python的调试构建。不幸的是，这只会导致我进一步构建错误！
