Hi, I am trying to install minimu9-ahrs on my raspberry pi3 but I find some error with "eigen" :

Package eigen3 was not found in the pkg-config search path. Perhaps you should add the directory containingeigen3.pc' to the PKG_CONFIG_PATH environment variable No package 'eigen3' found g++ -I. -Wall --std=gnu++11 -O2 -MD -MP vector.h -o vector.h.gch vector.h:5:10: fatal error: Eigen/Core: Aucun fichier ou dossier de ce type

include <Eigen/Core>

      ^~~~~~~~~~~~

compilation terminated. make: *** [Makefile:37: vector.h.gch] Error 1`

could you please help me resolving this problem ? thanks

It looks like you didn't install Eigen. Did you see this part in the README?

To build minimu9-ahrs, you first need to isntall some libraries that it depends on. On Raspbian, you can install these dependencies by running:

sudo apt-get install libi2c-dev libeigen3-dev libboost-program-options-dev
