General Error Handler VI makes it impossible to compile an app

Solved!
Go to solution

Just reported this as a bug to NI.

 

The General Error Handler VI is not usable on LabVIEW for Linux.

 

The root issue is in the popup dialog sub-vi, t turns out the event structure with a "key down?" event is not handled the same on Windows and on Linux.

 

So if you make a LabVIEW app and plan to compile it for Windows and Linux, avoid using "key down?" events and you also can't use the General Error Handler VI.

Oh, and it's fixed in LabVIEW 2021.

After some more digging with NI Tech support, it seems this issue is only occurring on my Ubuntu 20 (not officially supported by NI) and my OpenSuse Leap 15.2 (only 15.1 is supported by NI...)

NI Tech support gave me an OpenSuse 15.1 VM with LV2020 and it all works.

AND the issue comes when installing the LV 2020 SP1 patch

After that, the event structures, invoke node, property node (and maybe other stuff) don't mnake sense anymore.

I am facing the same issue with the general error handler with the official NI PXI Linux RT... 2023.

 

i can build the rtexe and run it on the system. but when i try to debug something, by starting the vi via windows on my PXI, it crashes while deploy process...

 

 

cant imagine i am the only one who ran into this issue with all the new Linux PXIs out there?
