ブーストiostreamでのQTリンカエラー

Question

msvc2010を使用してQt 5.5アプリケーションをコンパイルしようとしています。しかし、私がそれを構築しようとすると、boost :: iostreamsに関連するいくつかのリンカエラーが発生します。

libboost_iostreamsの.libライブラリがBoostライブラリディレクトリで利用可能で、もしあれば、正しくディレクトリをリンクにリンクされ、リンカプロジェクト設定でライブラリがリンクされている場合は、チェックする必要があります。

ブーストをコンパイルしていて、ブーストコンパイルに疑問がある場合（いくつかのプロジェクトを除く多くのオプションでコンパイルできます）、sourceforge [1]で使用可能なプリコンパイル済みバイナリを使用できます。
