LinuxCNC on Debian 10 Buster quick and easy install

Irak

Thanks a ton. Did my installs always as root. A decent password is there. Thanks also for he hint on modifying /etc/sudoers.d/local. I will consider that for my son, who is using my cnc's too.

But does LinuxCNC still work with sudo disabled?

(I don't know the answer, I have not done the experiment).

LinuxCNC needs to be able to load and unload kernel modules. For that reason, (at least with a run-in-place self-compiled version) it needs to be setuid root in order to work with access to hardware such as the PCI bus.

Had the stock iso installed this weekend. I guess I was somehow not clear when stating that I always set a root passwd. I do so *after* the standard grafical install. Thus sudo is not being disabled and LinuxCNC runs just fine.

Besides: Excellent work with 2.8.0 iso! Thanks a ton!

Hi, I am trying to install linuxcnc from the github repository github.com/LinuxCNC/linuxcnc/tree/2.8 , since I want to install ethercat to my pc, and the image that you put 'http: // buildbot. linuxcnc.org/ stretch 2.8-rtpreempt 'does not work for me for this, at the moment of wanting to build linuxcnc as cnc from the git repository

1. Install linuxcnc
$ linuxcnc / debian / => ./configure uspace => cd ..
$ linuxcnc / => dpkg-checkbuilddeps => sudo apt-get install ..... until you are done.
$ cd src / => ./autogen.sh => ./configure => make -j2 (j2 = dual processor speed)
$ sudo make setuid

When I try to make the src folder I get the following error in console:
"Makefile: 82: *** Makefile.inc must specify RTPREFIX and other variables."

Do you have any idea why it happens or information about where they talk about it?

since i searched and the information i found is from linuxcnc 2.6

(old ubuntu 12.04.5 LTS linuxcnc 2.7 user)

you need ./configure --with-realtime=uspace

linuxcnc.org/docs/master/html/code/build...cnc.html#Quick-Start

hi phillc54, the command you show me when you enter it shows me the following error:

"configure: error: invalid variable name:"

linuxcnc dependencies already installed them all as mentioned on the page, as mentioned here:

$ linuxcnc / debian / => ./configure uspace => cd ..
$ linuxcnc / => dpkg-checkbuilddeps => sudo apt-get install ..... until you are done.
$ cd src / => ./autogen.sh => ./configure => make -j2 (j2 = dual processor speed)
$ sudo make setuid

all the steps served me just the error occurs at the time of make.
