rtapi -- uspace -- "Using POSIX non-realtime"

You should not need to chmod anything.

"sudo make setuid" changes some permissions, but that is all that should be changed, and you should use the script, not do it by hand.

Hi andy

Thanks a lot for your help and sorry for the delay, I'm in a hurry lately.

I did CHMOD because I had permission problems:

avc@avc:~/LinuxCncRip/src$ sudo make setuid
chown root ../bin/rtapi_app
chmod 4750 ../bin/rtapi_app
chown root ../bin/linuxcnc_module_helper
chmod 4750 ../bin/linuxcnc_module_helper
avc@avc:~/LinuxCncRip/src$ cd ..
avc@avc:~/LinuxCncRip$ cd scripts/
avc@avc:~/LinuxCncRip/scripts$ . ./rip-environment

avc@avc:~/LinuxCncRip/scripts$ linuxcnc

There is something strange going on here, it seems.
Who owns linuxcnc-dev?
Try then check the permissions in linuxcnc-dev (should all belong to your user)
then the sequence.

Hi Andy
if there are permissions problems this maybe help.

Must I reinstall all root programs without use sudo commands?

I don't know for sure, but my linuxcnc-dev directory is owned by my user.

I would be tempted to chmod that to yourself and see if it helps.

(Or just re-clone it without a sudo)

Is this possibly related?
