Axis segfault?

Hi,

Friend of mine wants to set up machine with LinuxCNC.
Fresh install from CD, normal AXIS/ini/hal settings, but he gets debug information like this:

debug message on pastebin

Is this PC hardware related error (memory, motherboard)?
Or maybe parport error?
Could be graphic card or driver?

Thank you for your assistance.

Hi

[ 199.558354] axis[1678]: segfault at 0 ip (null) sp bfcd53bc error 4 in libBLT.2.4.so.8.5[110000+de000]

libBLT is a graphics library for blitting,(copying patterns to a frame buffer and applying mathematical processes to them etc). I imagine it is used by OpenGL, which Axis is heavily dependent upon for rendering.

The first thing to do is to try to run a sim, not a real config, I see you are running the sherline4axis. Use the axis_mm.ini.
This will eliminate a problem with the config or the directory name as JT suggests

If that causes same problems, try changing the .ini file line under
[DISPLAY]
DISPLAY = axis
to
DISPLAY = xemc
and try again

If this works, the problem is probably with openGL

Then need to start looking at what graphics card etc you have and what driver you are using.
Proprietary nvidia drivers are notorious for causing openGL problems.

Hi John,

Thank you for the hint. The minus sign is not a problem, I renamed it, but the error message still exists.
This kind of config names are created normally on my 2.6-sim too, when I generate more than one config for the same machine type (sim, sim-1, sim-2, hm2-stepper-1)

Hi ArcEye,

Most probably the problem was caused by the graphic card or its driver. Because it was an older motherboard with built in VGA chip, we changed the whole MB to newer one and the same config works now. Anyway, thank you for the advice, I'll save this "xemc" trick for the future, when I encounter strange graphics related issues.
