I upgraded to Debian 12 and LinuxCNC v2.9.3 and find I can no longer build.
Linux debian2 6.1.0-22-rt-amd64 #1 SMP PREEMPT_RT Debian 6.1.94-1 (2024-06-21) x86_64 GNU/Linux
Downloaded 2.9.3 tarball from git yesterday.
I kept pretty good notes on building with 2.8.x and can't find anything I previously encountered related to this. I can Make just my own code but when I do the full Make I get the following:
I'd appreciate if someone could suggest how to proceed. This doesn't seem to involve any code under my control.

Looks like I had conflicts because I needed to remove
linux-image-4.19.0.9-rt-amd64
Now it builds as expected.
I thought I followed the upgrade instructions exactly, but either I missed that step or they did not mention it.

You actually upgraded an existing Debian 10 installation to Debian 12 ?
I thought it was a new install, despite the statement, sorry.
Personally, i never ever upgrade existing installations since Ubuntu 10.04 to 11.04, it failed miserably, so i never bothered, i just do a clean install, much faster and does not come with baggage!
