I'm using Eigen to deal with some problems in a huge project.
But when I build the project, a error comes up says:
YOU_MIXED_DIFFERENT_NUMERIC_TYPES
But the error information doesn't tell which line cause this error, and the project is too large, I can hardly find that position.
Is there any way to find the position causing the problem and debug this error?

You can easily find it by looking at the compiler error message. All compilers outputs the call-stack that triggered any error and warnings.

Sorry, I couldn't find how to show call stack trace for compiler error in Visual Studio 2013. In VS's error list window, only a error message says "YOU_MIXED_DIFFERENT_NUMERIC_TYPES ... " shows without any other information.
Do you have any idea to deal with it in Visual Studio?
