I am programming with C++/CLI on Visual Studio 2008. Before adding the directory of Eigen, my program works well, but after I have added the directory and added only one line in a header file:
#include <Eigen/Core>
then the compilation fails, the errors are:
1>d:\setup\eigen-eigen-26667be4f70b\eigen\src/Core/util/Meta.h(389) : error C2039: '()' : is not a member of 'System::Object'

I have researched the errors by google and this forum, still no luck, any help would be appreciated. BTW, I am using the the newest version of Eigen.

Thank you.
