尝试为c ++ interop自动生成库时出错

Question

我正在使用pybindgen在python和c ++之间创建链接代码。或者至少我会是如果我可以使用我的代码。运行时的python文件会产生以下错误。我能以任何方式满足pybindgen或解决这些问题都会非常有帮助。

Answer 1

只是一个猜测，但是从您的错误消息中，您可能会遇到路径问题。请注意src和tokeniser之间的路径标记。 C:\Users\Richard\workspace\PyBindGen\src\/tokeniser.hpp:13

Answer 2

这不是一件容易的事，但现在就是这样。

我删除了所有“using namespace std;”和我的代码中的任何其他“使用”项目，所以使用“std ::”来表示标准库中的任何内容。这摆脱了size_t名称冲突问题。这看起来很多，可能是标准库的c ++标准/ MinGW实现与GCC_XML不兼容。换句话说，c ++标准允许GCC_XML无法理解的名称空间声明，因此会产生冲突。

请注意，这似乎不会影响名称空间中的内容。所以这很好。

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

其他问题来自于我没有声明pybindgen关于boost库依赖性的问题。这是修改后的.py文件。
