c++ - 尝试为 c++ 互操作自动生成我的库时出错

Question

我正在使用 pybindgen 创建 python 和 c++ 之间的链接代码。或者至少如果我可以让它与我的代码一起工作，我会这样做。python 文件在运行时会产生以下错误。我可以满足 pybindgen 或解决这些问题的任何方式都将非常有帮助。

Answer 1

这不是一件容易的工作，但它就是这样。

我删除了所有“使用命名空间标准；” 以及我的代码中的任何其他“使用”项目，因此将“std::”用于标准库中的任何内容。这摆脱了 size_t 名称冲突问题。这似乎解决了很多问题，可能是标准库的 c++ 标准/MinGW 实现不能与 GCC_XML 很好地配合使用。换句话说，c++ 标准允许 GCC_XML 无法理解的命名空间声明，因此您会遇到冲突。

请注意，这似乎不会影响命名空间中的内容。所以这很好用。

namespace Hello
{
    void func()
    {
        printf("Hello World");
    }
}

其他问题来自我没有向 pybindgen 声明关于 boost 库依赖的足够多的内容。这是修改后的 .py 文件。

只是猜测，但从您的错误消息来看，您可能遇到了路径问题。注意 src 和 tokeniser 之间的路径标记。C:\Users\Richard\workspace\PyBindGen\src\/tokeniser.hpp:13
