c++ - C++相互運用機能用のライブラリを自動生成しようとしたときのエラー

Question

私はpybindgenを使用して、PythonとC++の間のリンクコードを作成しています。または、少なくとも、自分のコードで動作させることができればと思います。実行時にPythonファイルを実行すると、次のエラーが発生します。pybindgenを満足させたり、これらの問題を解決したりする方法は、非常に役立ちます。

Answer 1

推測ですが、エラーメッセージから、パスの問題が発生している可能性があります。srcとtokeniserの間のパスマーカーに注意してください。C:\Users\Richard\workspace\PyBindGen\src\/tokeniser.hpp:13

Answer 2

これは簡単な回避策ではありませんでしたが、ここにあります。

「usingnamespacestd;」をすべて削除しました。そして、私のコードからのその他の「使用」アイテムは、代わりに標準ライブラリからのすべてに「std::」を使用しました。これにより、size_t名の競合の問題が解消されました。これはかなり整理されているようで、おそらくGCC_XMLではうまく機能しない標準ライブラリのc++標準/MinGW実装です。言い換えると、c ++標準では、GCC_XMLが理解できない名前空間宣言が許可されているため、競合が発生します。

これは、名前空間にあるものには影響しないように見えることに注意してください。したがって、これは正常に機能します。

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

他の問題は、Boostライブラリの依存関係についてpybindgenに十分に宣言していないことから生じました。これが変更された.pyファイルです。
