Visual Studio 2008 でオープン ソースの C++ プロジェクトをビルドしようとしています。ソリューション ファイルをロードすると、すべてがコンパイルされますが、特定のメソッドが見つからないため、多数のリンク エラーが発生します。DUMPBIN.EXE を使用して問題の .lib ファイルを調べた後、問題が何であるかがわかります。.lib 内のメソッドはすべて__cdecl署名されていますが、リンカーは代わりに同等のメソッドを探してい__thiscallます。
__cdecl代わりにVS 2008 を使用するにはどうすればよいですか?
注: このプロジェクトは、 OpenCV に基づくマルチタッチ追跡プログラムである CCV のフォークです。このフォークの目的は、カメラのメーカーが提供する FlyCapture2 ライブラリを介して、Flea3 と呼ばれるカメラのサポートを提供することです。リンカー エラーは次のとおりです。
