eigenpy moveit_commander - ImportError undefined symbol [closed]

edit

Hi all, I have a simple python script inspired by the moveit tutorials using moveit_commander.

I'm using:

• ROS Melodic on Ubuntu 19.10 compiled from source
• MoveIt compiled from source, branch master
• Python 2.7
• boost 1.67.0

It has always worked with no problems until a few days ago when I have probably done a clean build after some updates and it started doing this:

lrinelli@laptop:~$ rosrun test_pkg test_print_state.py __ns:=edo

Update: using catkin install and then catkin build --force-cmake --pre-clean I managed to complete a build. I tried again with catkin config --no-install and catkin build --force-cmake --pre-clean and the build does not complete.

• Which version of eigenpy should I use to build moveit master from source?
• From where should I download eigenPy?
• Is the first error actually related to eigenpy?

Thanks in advance
