Usage of package under linux - Import errors #152

Closed jeferal closed 5 months ago

Hello,

We are very interested in using the library under linux to communicate with servos using Ethercat only.

At the moment, importing the MotionController module fails with this error: from ingeniamotion import MotionController

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>

ImportError: cannot import name 'HRESULT' from 'can.ctypesutil' (/home/jesusferrandiz/robot_automatic_validation/venv/lib/python3.8/site-packages/can/ctypesutil.py)

We have an application working for us in Windows where we communicate with the servos through ethercat only using: mc.communication.connect_servo_ethercat

Is it actually possible to achieve this in linux?

Thank you for your help in advance.
