LinuxCNC on Debian 10 Buster quick and easy install

If I am putting it without the spaces exactly like this

./configure --with-realtime=uspace

But the make still doesn't work

OK.

Clone Linuxcnc in to a completely new and separate directory, and checkout the branch you wish to build. We'll going to call it new-linuxcnc-dev. I have no idea what has happened, but lets start from scratch.
If that doesn't work you will have to supply more info about your system. ie what kernel are you using, I'm assuming you are using Buster. And can you also copy all text from the screen after you start make up to the point it fails.

uname -a:
Linux user 4.19.0-11-rt-amd64 # 1 SMP PREEMPT RT Debian 4.19.146-1 (2020-09-17) x86_64 GNU / Linux

distro:
Ubuntu-Buster

Linuxcnc:
2.8

I'm downloading branch 2.8 in zip format, from here:

github.com/LinuxCNC/linuxcnc/tree/2.8

Since if I clone it from github by DEFAULT this is the master branch and I don't know how to make it change version:

github.com/LinuxCNC/linuxcnc.git

Change into the directory you have cloned into and

already look like in this link:

forum.linuxcnc.org/32-documents/34495-in...al-version-git-clone

hi beagle,

installing linuxcnc git checkout 2.8 was fine, at the time of doing the instruction
"sudo make setuid" I get the following:

chown root ../bin/rtapi_app
chmod 4750 ../bin/rtapi_app
chown root ../bin/linuxcnc_module_helper
chmod 4750 ../bin/linuxcnc_module_helper
Now you need to run 'sudo make setuid' to be able to run it instead with hardware access.

but when reviewing, linuxcnc has not yet been installed on my machine I tried "linuxcnc in terminal" but I get that it doesn't recognize it, I still need something to install?
