Building RTAI 5.2 Packages, some questions

Hi,

In one of my post I'm complain with latency. DomCa tell me that he's got best result with RTai.
Now, I'm trying to make a partition for LinuxCNC with RTai 5.2.
For this purpose I'm following this .

I start with the current LinuxCNC live install because I don't know from where to go.
For this time every things looks like good.

I'm about to "Make RTAI application packages". I don't what to do with these instructions :
Can you explain what to do ?

sudo ./autogen.sh

Not a error. RTAI directory was were under root user. A chmod restore the normal situation.

Step by step ...

return this : I take a look on github.com/SebKuzminsky/rtai/tree/old-3.9-debs/debian . This git contains a directory named "base" that cannot be found in my RTAI directory.
Is it the origin of the error ?
Did I have to copy it from git and how to ?

Are you aware of my precompiled RTAI repository?
github.com/andypugh/RTAI/releases
You need to expand "assets" to see the files.

That should get you straight to a working RTAI + LinuxCNC 2.8

Hi
A long time ago (2019), due to my lack of Linux knowlege, I wath thought it was necessary to compile RTAI for using it.
Reading again and again the LCNC documentation I found the simple way to get RTAI. All was writing in the manual.
linuxcnc.org/docs/stable/html/getting-st...#cha:Installing-RTAI
Now LinuxCNC works with RTAI !

It is also possible to run the normal (uspace) version of LinuxCNC on an RTAI kernel.

If you install linuxcnc-uspace (which will be an officlal Debian package in the next Debian release) then also install the package linuxcnc-uspace-rtai (deb package here: www.linuxcnc.org/dists/buster/2.8-rtpreempt/binary-amd64/ ) then LinuxCNC will run using LXRT realtime in user space on the RTAI kernel.

This combination seems to give good latency in my testing, but does not support the Mesa ethernet cards (I have not investigated if this is a real issue or simply the driver running a too-naive check)

after yesterday announcement, downloaded and installed 2.8.4 rtai. Works fine!
