Hello, I've re-reported the bug upstream: https://bugs.gentoo.org/708184 Meanwhile it gets fixed, I've answered in another issue a workaround you can do to keep working: I hope it helps. |

You can find some ready-to-use already built images here: https://github.com/awesomebytes/sbre_robot_ros_gentoo_prefix/releases They come from this discussion: #4 |

Hey @AndrewJSchoen I just commented in: #2 that I expected something like that to happen. There may be something interesting for you in what I wrote already. I've never installed For my pepper_os image I just extract the qi Python library somewhere. And I add to my PYTHONPATH in my I also needed to edit a If this becomes necessary for everyone (oh, and also, if it works), I'll propose to add that to the Dockerfiles so users don't need to fight it. ***Edit: I just saw in the release history it's actually very recent. Oh well, that was wrong, my bad. I can only say to try to install it in .local by doing |

@awesomebytes I can try the user install. I think I tried that at some point, but will let you know in any case. If it fails, I can look into the extracted version. For what it is worth, I am currently trying to install on the pepper ( |

@AndrewJSchoen If it's for Pepper, you may want to take a look into https://github.com/awesomebytes/pepper_os instead. It does come with A LOT of stuff that you may find useful (ok, maybe too much? but that's just some disk space lost). Just make sure to read the warning in the README about deploying it in your robot. I can assure you that it works (at least with Kinetic) as our robots work with it. I haven't done a deployment from scratch in a while... but nothing major has changed in months. That image includes ROS navigation, ROS perception, Tensorflow, teb_local_planner, dlib... well a lot of stuff. It's listed in the README. Now that I think about it, I think I didn't update it with naoqi_driver, but I can try to add it when I have a bit of time from the work I did in this repo. Btw this may work on the NaoV4 out of the box... but having a single core Atom 1.6GHz with 1GB RAM and limited disk space... You won't be able to run much on it. |

@awesomebytes Thanks for all the help. I did end up going the pepper_os route, and things worked great. |
I was attempting to run the
ros_kinetic_32branch instructions on a 32-bit Ubuntu install (18.04), but I get the following error during stage 3:Any suggestions on what might be the issue?
