Hi,
I've followed the Getting Started instructions and included the header files in my C++ project in Visual Studion 2015 but when I #include "Eigen/Dense" and try to compile I get a huge number of errors as below. Any suggestions would be much appreciated.

Make sure you are not including conflicting other header files or that you are using weird compiler flags. Also, which Eigen version are you using?

I'm using Eigen 3.2.8 and I am trying to add it to a legacy MFC project which I have just inherited, the command compiler flags are:
