Yes, there was another update after that.

Thanks for confirming

The problem has been found and a correcting PR made.

There was an unexpected knock on from another recent change,
which did not show up in test builds and even allowed
packages to build without errors,
despite them not having setuid on required files and flavor
segfaulting and not getting the proper kernel flavour, so it
defaulted to posix.

The build process will take a while, I will advise once new
packages are available, until then do not update

Reverting to the packages I suggested will work if you are
desperate to use your system and have the non working
packages installed

Can you try running the flavor binary in /usr/libexec

Running flavor on its own should give the kernel flavour

Also run flavor -m , flavor -b and flavor -d

This seems similar to Simon Mali's problem when he
upgraded, the kernel flavour was not being detected and a
default of posix was being tried.

Re: [Machinekit] Machinekit not starting: seems to be attempting to start incorrect rtapi app

[schoone...@btinternet.com]

  
  
Can you try running the flavor binary in /usr/libexec

Running flavor on its own should give the kernel flavour

Also run flavor -m , flavor -b and flavor -d

This seems similar to Simon Mali's problem when he upgraded, the
kernel flavour was not being detected and a default of posix was
being tried.

Looks like you forget to 'sudo make setuid' after building machinekit. Go to 
src/ and do that. Then retry.

[Machinekit] Machinekit not starting: seems to be attempting to start incorrect rtapi app

[Brian Schousek]

I'm trying to get a basic Machinekit up and running on an older PC. I've 
apparently successfully installed and started an RT-PREEMPT kernel (see ref 
1), properly installed the appropriate machinekit packages (see ref2), and 
tried to start things up with various configurations. Ref 3 shows a 
representative error (through iterations I determined that just trying to 
run 'realtime' yields the same errors as starting the whole package, and 
errors out much quicker.) My interpretation of ref 3 is that it is trying 
to run rtapi_posix (not installed) instead of rt-preempt. As can be seen in 
ref 4 there is an executable for rtapi_app_rt-preempt but no 
rtapi_app_posix so it's no great surprise there is an error in ref 3.

What simple thing am I missing here? I've been unsuccessful in finding a 
solution in this forum and on the machinekit website.
