OK, found out these things:
* environment variable QI_SDK_PREFIX must not be set (wrongly)
* removing all the config files from older versions in .config may help:
* "Softbank Robotics", "naoqi", "qimessaging", "choregraphe", "Aldebaran Robotics"
After this, the crash disappeared and the 3D display worked
Is anyone from support actually ever attending to these forums?
I am not part of the Support Team, but in my case to make Choregraphe even run on my System (Ubuntu), I needed to do some post installation steps. Maybe you can try them if you haven't already:
Post Installation Steps Choregraphe 2.8 Linux:
cd /opt/Softbank\ Robotics/Choregraphe\ Suite\ 2.8/lib/
sudo mv libz.so.1 libz.so.1.bak
sudo ln -s /usr/lib/x86_64-linux-gnu/libz.so libz.so.1
Thanks - yes, I actually forgot that there was a problem with libz as well, I solved it in a similar way by copying into the choregraphe lib dir.
Running Choregraphe 2.8.7 on Ubuntu 22.04 with a Nvidia graphics card.
This worked fine for a while, no Choregraphe shows that the 3D is crashing on startup every time I run it.
Same happens with previous versions of Choregraph (tested 220.127.116.11)
Working with this software is incredibly frustrating, web pages keep moving, when trying to find information one often finds outdated documentation, the API documentation is extremely lacking.
It seems to be impossible to get support easily either.
How to figure out what is wrong, how to correct this problem, how to submit a bug report for Choregraphe?
PS: even this forum is badly made, e.g. the even after logging in one gets annoyed with an I am not a robot visual challenge which is embedded in a tiny Iframe so one cannot even see all of the image to choose from at the same time!
