Hello,

I'm seeing a very weird error while extending the MatrixBase class as
explained in http://eigen.tuxfamily.org/dox-3.2/Topi ... Eigen.html

I have defined my additions in MatrixBaseAddons.h file and then, before including the
Eigen with #include <eigen3/Eigen/Dense>
I define the macro as #define EIGEN_MATRIXBASE_PLUGIN "MatrixBaseAddons.h"

However, when I compile my project with
g++ -std=c++11 test.cpp -o test

I see the following error

In file included from /usr/local/include/eigen3/Eigen/Dense:1:
In file included from /usr/local/include/eigen3/Eigen/Core:410:
/usr/local/include/eigen3/Eigen/src/Core/MatrixBase.h:130:15: fatal error: 'MatrixBaseAddons.h' file not found
# include EIGEN_MATRIXBASE_PLUGIN
^
./matrix.hpp:12:33: note: expanded from macro 'EIGEN_MATRIXBASE_PLUGIN'
#define EIGEN_MATRIXBASE_PLUGIN "MatrixBaseAddons.h"

I don't understand what I'm possibly doing wrong with this.

My MatrixBAseAddons.h file is placed where my test.cpp file is.

I'm scratching my head because I cannot really find out what can go wrong here
It looks very simple thing but is not working...

Thanks in advance for your help,
Jack
