Can be solved by updating the path to: #include <eigen3/Eigen/Dense>. Believe this was solved back in January, but the issue resurfaced today.

What is the exact diff in your local folder? Sorry about the regression - some well intended cleanup didn't apparently really work.

Lorenz,

The only thing missing was eigen3 before Eigen in the path. I believe this is the same issue that happened back in Jan (posted here: https://groups.google.com/forum/#!searchin/px4users/eigen/px4users/3ttWk0GpwtU/9KTqh7-GFgAJ ), but I just forked that repository today to start working and had the same issue with make.

After fixing the eigen issue I ran into the same optic flow sensor follow-on issue as #4195, but removing Gazebo7 and installing 6 fixed the issue. Somewhere in your previous instructions they noted Mac users must install Gazebo7, but I believe you've since removed that comment.

Thanks for all the great work on this SITL simulation.

-Traci.

Can you please give me the output of git diff in Tools/sitl_gazebo? I don't understand what you changed.

Sorry it was unclear. I did not make changes in Firmware/Tools/sitl_gazebo

Here is the output of git diff from ~/PX4_src/sitl_gazebo where I made the changes:

Ok, pushed something equivalent to master.
