Eigen Plugins Order

[pfankhauser]

Currently, there's an error when Eigen is not loaded at first from grid_map_core because of the Eigen Plugins.

When I am using "#include "grid_map_cv/grid_map_cv.hpp", I get the error

/opt/ros/kinetic/include/grid_map_cv/GridMapCvConverter.hpp: In static member function ‘static bool grid_map::GridMapCvConverter::toImage(const grid_map::GridMap&, const string&, int, cv::Mat&)’:
/opt/ros/kinetic/include/grid_map_cv/GridMapCvConverter.hpp:136:47: error: ‘const Matrix {aka const class Eigen::Matrix<float, -1, -1>}’ has no member named ‘minCoeffOfFinites’
     const float minValue = gridMap.get(layer).minCoeffOfFinites();

Has it got something to do with this issue, or how can I resolve it?

I have created a minimal project, and tracked it down to this:
Problem does not occur:

#include "grid_map_cv/grid_map_cv.hpp"
#include "Eigen/Eigen"

Problem does occur:

#include "Eigen/Eigen"
#include "grid_map_cv/grid_map_cv.hpp"

Yes, that's the problem we're facing when Eigen is included first, as Grid Map relies on Eigen Addons that are loaded through macros: http://eigen.tuxfamily.org/dox/TopicCustomizingEigen.html

I'm not sure how to resolve this nicely, any hints are appreciated.

Thanks to @djud and @hogabrie for resolving this with https://github.com/ethz-asl/grid_map/pull/73!

Hi @pfankhauser the pull is no longer available and I still have the same problem, do you know how to solve this? thanks
