Fatal Errors Installing on Parallels.

Have upped the VM's RAM to 2G (my usual allocation for a VM) from 768M. No effect.

Updated to 2.7.4. No effect.

Debug file information:
/usr/bin/linuxcnc: line 857: 9415 Segmentation fault $EMCDISPLAY -ini "$INIFILE" $EMCDISPLAYARGS $EXTRA_ARGS

Parallels doesn't offer much to tweak for the display.

Increased display memory from 128M to 256M. No effect.

Turned off 3D acceleration. No effect.

Disabled vertical synchronization. No effect.

Reverted all display parameters to previous values: 128M, 3D acceleration on, vertical sync enabled.

New error log attached.

Installed software-based OpenGL using

sudo apt-get install libgl1-mesa-swx11

No effect. Seg error at the same line number.

I've put a fair amount of time and effort into this without success.

Andy mentioned that he runs LinuxCNC axis sim on VMWare Fusion. I can take a hint. Right now I'm using a trial of Fusion, but I will definitely be buying it. Remains to be seen whether I replace Parallels (which is excellent, other than this one problem) or run both.

If anyone gets LinuxCNC axis running on Parallels, I'd like to know about it. If you're just trying to get it running, use Fusion.

Out of curiosity, I tried the 2.7 Live CD with VirtualBox on my old Mac, and it runs without problem (With default settings, that is only 12MB video memory and no video acceleration).


From your log file:

Is very strange because it is the python executable crashing in libc -- that does not happen very often.

Does it generates a 'core' somewhere? that would allows us to get at stack trace...

I haven't solved the problem, but I've got where I wanted to go by using Fusion instead.

If you want to pursue the error, I will help. I threw away the Parallels VM, but I am sure I can reproduce the error. How do I get you the core ?
