I am building a project with OpenCV in C#. It requires a dll file called cvextern.dll. but, when adding this file as a reference, this message appears :-
a reference “cvextern.dll” can’t be added, Please make sure that the file is accessible and that it is a valid assembly or COM component.
I get tired from searching, I spent the past 2 days in searching for a solution for that problem
the file is a native DLL which means you can’t add it to a .NET project via Add Reference… you can use it via DllImport (see http://msdn.microsoft.com/en-us/library/system.runtime.interopservices.dllimportattribute.aspx)
