Hi.

I was trying the following tutorial to install linuxcnc on ubuntu 12.04:

wiki.linuxcnc.org/cgi-bin/wiki.pl?LinuxCNC_On_Ubuntu_Precise

but when I try to run it, I have this error:


RTAPI: ERROR: failed to map shmem
RTAPI: Locked memory limit is 64KiB, recommended at least 20480KiB.
This can cause the error 'failed to map shmem'.
For more information, see
	http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?LockedMemory

(...)

I tried to add the "* - memlock 20480" line on the recommended file, but it exists already....

so what I can do to solve this? I'm using the "precise master-rt" version of linuxcnc.

Thanks,

João Tiago

Hi

Did you also try the rest of the solution?

For Ubuntu Lucid (10.10), also add the following line at the end of /etc/pam.d/common-session

session required pam_limits.so

Log out and log back in.


I would imagine you can read 10.10 as >10.04

EDIT: If that does not work you can always add ulimit -l 20480 to your .bashrc file in your home directory

regards
