Linuxcnc would not run

Hi everyone,

I am a new user of LinuxCNC and I am having trouble in running linuxcnc.

I tried opening the application on my desktop and from terminal too and nothing happen.

Not sure what went wrong and I have found this files in the home directory.

Anyone know what should I do to make it running in machine control?

Thanks,
J

Hi

There is next to nothing in those attachments, you need to capture the full output before we can help you.

If that is all you get and nothing shows in a terminal when you run linuxcnc, then run in a terminal again and immediately afterwards run
dmesg > dmesg.txt
and attach the file dmesg.txt that is produced

regards

Thanks for the respond

After couple of hour fight with the software I realize that the linuxcnc installed were a run-in-place version.

However, I can't open up into "Show Hal Configuration" for some reason, I have attached the dmesg for this issue.

Do you have a reason to do it this way rather than use the precompiled and released packages?

Though that was a good way to learn linux. What I was trying to do, is to install a linuxcnc 32 bit into a 64 bit Ubuntu 14.04, where I found a step by step approach installation of linuxcnc by anderswallin.

I felt like I am being silly now

There is nothing relevant in dmesg, just a suggestion that there could be an issue with parport access.
But as I have no idea what you were running or if you even have a parport......

It would be a good idea from a support point of view to install one of the 32bit distros, on a separate partition if necessary.

Running on a 64bit platform is perfectly possible, I am doing it now, but it does rather leave you to sort out any problems yourself.

Thanks ArcEye. I had attached details of my parport and copied the error shown in my terminal when I tried to run linuxcnc. From that error, is there a possibility that I had wrong real-time kernel running/not-running?

I am keen to learn and get linuxcnc running in 64 bit, would like to give it another shot first before going into 32bit distros, on a separate partition option.

Well, you are getting a learning experience for sure, but you might not be learning what you wanted to learn.

Thanks andypugh. Please advice.

Hi

You need to attach your ini and hal file as well and tell us exactly what you are running.

The only bit in the errors that is useful, suggests you are running a rt-preempt kernel?
Did you configure the build with ./configure --with-realtime=uspace ?

From lsmod, this is the cause of the suggested problem I saw in dmesg

parport_pc 32701 2 parport_serial
ppdev 17635 0
lp 17759 0
parport 42372 3 lp,ppdev,parport_pc

and this from lspci

You need the parport driver, because that is the low level access driver that all modules go through, but you definately do not want the others

Before you start linuxcnc, from a terminal run
rmmod parport_serial
rmmod parport_pc
rmmod ppdev
rmmod lp

If that was the only problem, hopefully it will now start and you can blacklist the print drivers in /etc/modprobe.d thereafter.

Need to know exactly what you are running and see the configs to go further
