I'm currently trying to install Shogun a machine learning toolbox and to use it with Python. I'm facing a problem with the Eigen3 package, when I try sudo port install shogun it gives me this error (log file):
:info:configure Error: Eigen3 not found
...
:info:configure ./configure-11619-9060.cpp:1:10: fatal error: 'Eigen/Dense' file not found
:info:configure #include <Eigen/Dense>
:info:configure ^
I've seen that some people say that changing to
#include "Eigen/Dense"
solve their problem, but I don't have access to this file, so I can't change it.
And if I type
$ ls /opt/local/include/eigen3/
Eigen unsupported
signature_of_eigen3_matrix_library
it gives me this, so I don't know what to try, any idea?
EDIT : I used this formula with these custom 2 lines
args = std_cmake_args + [
...
"-DBUNDLE_EIGEN=ON",
"-DPythonModular=ON",
...
]
Now it does not report any error, but it does not recognize shogun
$ ipython
In [1]: import shogun

You can add one of the following options to your cmake call to resolve this:
Either get eigen in you include directory
-DEIGEN_INCLUDE_DIR=/opt/local/include/eigen3/
or you can use
-DBUNDLE_EIGEN=ON
to make shogun download the eigen3.
