Hi,

I'm installing ROS packages on Ubuntu Armhf, and although so far everything went fine, I find a difference with electric. According to http://answers.ros.org/question/10940/eigen-in-ros/, eigen is a system dependency. However, I can't find such package for groovy, except eigen-conversions, eigen-stl, ecl-eigen. I installed them, but the installation keeps complaining eigen isn't there. Apart from cross-compiling which I try to avoid, is there any solution ?

Hi skiesel,

Thanks for your response.

I installed libeigen3-dev. Now I used

sudo find /usr -name eigen*

and found that eigen is installed in /usr/include/eigen3/Eigen. So apparently each installation goes different.

I actually came across a similar issue yesterday. I don't know if it's the exact problem you're having but just in case...

I found that Eigen was installed but it was installed here:

./usr/local/include/eigen3

My specific issue was regarding compiling against MoveIt! and the compilation was looking for "Eigen/Geometry", not "eigen3/Eigen/Geometry". I just created a simlink in that directory (./usr/local/include/) to resolve my problem:

cd /usr/local/include
ln -s eigen3/Eigen Eigen

You can check that everything is set by executing these commands:

cd /usr/local/include ls -l Eigen

And the output should look something like:

lrwxrwxrwx 1 root root   12 Oct 10 13:35 Eigen -> eigen3/Eigen
