Hey guys,

I'm trying to compile my objective C code in XCode. I have some C++ code that I use inside my objective C and I use Eigen library in my C++ code. The C++ code that uses the Eigen library compiles when I build it on VisualStudio on my windows computer. But when I'm trying to compile on a Mac in xCode, it fails; complaining about the Block.h file: "Unknown type name namespace".

I have not found anything on internet so I decided to post a question here to see if anyone can help.

Thanks

Please post the entire error message with all compiler flags. Also, how do you include Eigen's headers?

To include the header files I just copied and pasted the actual files into my include directory and added
#include <Eigen/Dense>
#include <Eigen/Core>

Is there anything else I need to do?
