Hi,
I have a small problem, I can't launch RoboDK on my Ubuntu 20.04. If I let the c++ API start it, it just crash with the error:

Code:

error while loading shared libraries: libQt5WebSockets.so.5: cannot open shared object file: No such file or directory

So I added to my .bashrc the lines from "~/RoboDK/RoboDK-Start.sh" and the software started, but crash after less than 1 second with a segmentation fault:

Code:

And at this point I don't know what to do.. I want to use RoboDK in an embedded way but I can't even manage to turn it on on a fresh Ubuntu 20.04 install

---

After further test, it seems that launching from the computer directly works, launching over ssh or with an headless computer cannot works.
Is there a way to launch RoboDK without the UI ? or does this require another version of RoboDK ?

And about the add to bashrc I had to make, I'm not sure this is the "clean" way to do it, how am I suppose to do it then ?

You can start RoboDK without the User interface or the OpenGL window by adding the -NOUI command line option.
