Describe the bug I’m trying to run Openpilot in Carla as described here: https://github.com/commaai/openpilot/tree/master/tools/sim When I execute

PASSIVE=0 NOBOARD=1 ./manager.py

in selfdrive/ I get the following error message:

scons: building terminated because of errors.
Traceback (most recent call last):
  File "./manager.py", line 135, in <module>
    add_logentries_handler(cloudlog)
  File "/home/tom/git/openpilot/selfdrive/swaglog.py", line 39, in add_logentries_handler
    from selfdrive.logmessaged import get_le_handler

    import cereal.messaging as messaging
  File "/home/tom/git/openpilot/cereal/messaging/__init__.py", line 2, in <module>
    from .messaging_pyx import Context, Poller, SubSocket, PubSocket  # pylint: disable=no-name-in-module, import-error
ModuleNotFoundError: No module named 'cereal.messaging.messaging_pyx'

Any idea what the issue could be?

Scons failed building. What do you get if run scons -j4 manually in the openpilot folder?

https://github.com/commaai/openpilot/commit/60f6e12debe7ed5f53076f3f1ab43fbd150d7087 should fix the confusing error. You still have an underlying build issue though.

@tom-doerr I assume setting the path fixed your issue. Closing this.
