python - 如何为 python C++ 嵌入构建 boost 示例

Question

Atm 我需要包装一个 C++ 库以便在 python 代码中使用。为此，我认为最好使用 boost python 扩展/包装器。但是现在我在编译文档中显示的每个示例时一直遇到问题。我能够让它运行 python27 和 boost_1_55 的组合，但任何东西(python34 boost_1_58)似乎都不起作用。以下是构建 2 个基本示例的错误消息(我正在运行 windows7 64 位):

Answer 1

我在 boost-python 教程中遇到了类似的问题。我认为原因是我没有 python 库的调试版本。为了解决这个问题，我将属性 variant=release 添加到我对 b2 的调用中。这解决了我的不兼容 pdb 文件的问题，尽管更好的选择是获取 python 的调试版本。不幸的是，它只会让我进一步构建错误!
