vuforia API を使用して拡張現実アプリケーションを作成しています。現在、別のライブラリ ( opencv ) を統合しようとしています。android.mkファイルに変更を加えました。しかし、私はまだopencvライブラリとQCARライブラリを同じファイル.cppで使用できません.Javaクラスにアクセスして、QCARを使用するファイルとOPENCVを使用するファイルをリンクしようとしましたが、このマッピングには時間がかかります. 同じファイルで 2 つのライブラリを使用する必要があります。これは私の android.mk ファイルです:
コメントで言及されているように、コードを編集します。

ImageTargets.cpp に opencv 関数を追加せずにプロジェクトをビルドすると、次のようになります。

このファイルで何が間違っているのですか?
