boost.pythonとboost.threadの両方を使用するとコンパイルエラー

Question

私の目標は、私のPythonコード用のマルチスレッドC++ DLLを書くことです。 Pythonコードの機能は、PCLを使用してポイントクラウドを処理するためにC++ライブラリを呼び出すことですが、C++ライブラリは自動的に新しいスレッドを生成してポイントクラウドを視覚化します。 私のboost.pyモジュールは、私のC++ライブラリにboost.threadを組み込むまで正常に動作します。私が得るコンパイルエラーは以下の通りです。

boost :: mutexまたはboost :: threadを使用するときはいつでも、このエラーが発生します。 このエラーを引き起こす原因は不明です。

多くの感謝！

OK、これは解決策ではないかもしれませんが、私は講師に尋ねました。彼は、ブースト・パイソンとそのスレッド機能の両方を使用すると間違っていると言いました。 boostの代わりにpthread libに変更した後、すべて正常に動作しています。

ただし、より洗練されたソリューションはいつでも歓迎します。
