QtDragon, Linuxcnc 2.9pre, and Debian 12 (bookworm)

I am open and anxious to help any way I can......

like lots of testing....

please just ask away...!!!
 

I just pushed the problems I found with drawing.
It comes with other updates mainly to qtdragon_hd - hopefully I haven't missed something there.
If you are compiling you can pull and test now. Buildbot usually takes quite awhile.

What kernel # are you using with bookworm?

thanks
Linux 4.19.0-9-rt-amd64

I have installed lcnc via the debian 12 repository. no clue where it gets its .deb's
what files did you have to modify?
if you post them here, could I use them? if yes, how???

OK,  i see them in src files.....3 files.  python.   
if I download and replace my existing ones with those, shouldn't it work?   python being a non-compiled coding and all.....
??

OK, again.....  I edited the existing files identical to your edits in src. 
but still get the same errors....
what gives?

Strange, Debian 12 BookWorm should have 5.nn kernels, not 4.19.
Give PhillC's script a try, it always worked for me on Debian and Mint for installing QT stuff:
forum.linuxcnc.org/qtvcp/38414-installing-qtvcp

I changed it with grub_customizer....
lots left over from earlier distros

apparently sometimes the 5.x isn't as good.
If 4.x works...
