DLLデバッグ情報

Question

DLLの実動ビルドを作成しました。私はvirustotalを使ってそれをスキャンしている間に、以下に示すように、結果報告デバッグ情報がファイルにあることに気付きました。誰かがこのデバッグ情報が何であるか教えてください。どうすれば削除できますか？ DLLはVisual Studio Community 2017を使用してビルドされたC++のものです。

デバッグ情報を持っていることをお勧めする一般的なアドバイスがありますので、私はデバッグ情報を必要としないとは言いません。他の誰かがこのデバッグ情報を取得します。

Answer 1

は、debugディレクトリが完全にリンカのコマンドラインに/NOCOFFGRPINFOを追加解消し、リンカ/最適化の下のリンクタイムコード生成をオフにするには（つまり、ドロップ/LTCG）、VS2017のリリースビルドではデフォルトで有効になっています。
