I've just installed RoboDK. Naturally, the first thing I did upon starting it up was to try to visit the library, but when I click the button (or select the menu item), there is no apparent response.

So I tried running it from the command line to see any log output, and when I try to open the library I see these messages:

So it looks like RoboDK is trying to use kde-open5 for something, and that's compiled against a different version of Qt from what is distributed with RoboDK. I had a quick hack and found that kde-open5 is actually being called by xdg-open - that's what RoboDK is calling out to.

So the issue is that LD_LIBRARY_PATH is being set by the RoboDK launcher (to point at the bundled Qt libs), but then RoboDK is trying to use the system xdg-open with that env var still set, and they're clashing.

This is a relatively low impact bug, since I can just open the library manually in my browser, but it was a bit of a puzzle since I initially thought a library was going to be opened within the application.

RoboDK version 5.6.0 for Ubuntu 64-bit
Debian 11.7 amd64

Bump, is there anything I can do to bring this to the attention of the devs?

This may be due to the Qt library that is being used. If you used the Ubuntu install on a Debian system it may have installed the wrong libraries.

Are you having the same issue if you use the RoboDK build for debian?
