Linuxcnc 2.5.2 won't run

Installed Ubuntu 12.04 than installed all of what I thought was required. After 2 days of upgrading adding. Linuxcnc won't run. I get the intial machine setup screen, the splash screen, but won't launch program.

The linux debug text file has the following

Can not find -sec MOT -var MOT -num 1

In your explaination PLEASE be gentle. I'm new to linux. http://www.cnczone.com/forums/images/icons/icon11.png

hal_parport: dlopen: /home/maura/linuxcnc-rtos/rtlib/hal_parport.so: cannot open shared object file: No such file or directory

thats your problem, if you have hal_parport.so maybe you can direct it to the correct location, or add a link to in where it thinks it should be.
you have a parallel port on your computer right?

the easiest way is to just install the livecd from the website.

Hi Alan,

went to website and could not find liveCD that has linuxcnc 12.04 with linuxcnc 2.5.2. I need to have linuxcnc 12.04 installed to run FlatCAM. So if you can help guide me to make the modification that you suggested, I would greatly appreciate it.

Thanks

About half way down the page - it explains on how to install linuxcnc 2.6 on 12.04 32bit

Please advice

Thanks

Did you update your repositories correctly so that it knows the location of the linuxCNC packages? This error shows there might be a typo or something in your repo:

Err LinuxCNC.org base/2.6 Sources
404 Not Found

Make sure your repository has:

deb LinuxCNC.org precise base 2.6

for 12.04.

Mark

hi wendtmk,

thanks alot for the help. It was what you said. I just needed to learn how to use the software manger. After running the app. I ran into an install issue. Please review and advise please.

You might want to run "sudo apt-get clean" from the command line. That error you are running into sounds a bit like some issues with the residual packages from the previous tries at the installation.

After that operation is complete, try again to download the linuxCNC packages.

Hi wendtmk,

Tried "sudo apt-get clean" from command line and it ran for only 1 or 2 seconds. Don't think it did anything, but ran install again and got this error;

Errors were encountered while processing:

E: Sub-process /usr/bin/dpkg returned an error code (1)


I have no idea what this means or what to do. If you can please advise.

Thanks

After another install attempt, I dicided to try and run program; got this message:

Okay, try this then:

sudo apt-get remove -pruge rtai-modules-3.4.55-rtai-2_3.9-shabby-memleak

Then you'll need to reinstall linuxCNC.

Your errors above are because rtai was not fully installed.

Mark

if -pruge doesnt work try -purge
Im guessing that was a typo.

have you tried flatcam on the 10.04 livecd? I see it was tested on 12.04 but I didnt see anywhere that it is required.

Hi Alan,

Thanks. I understood it to be purge from the start. I am getting still a syntax error. Please review;

maura@ubuntu:~$ sudo apt-get remove -purge rtai-modules-3.4.55-rtai-2_3.9-shabby-memleak
E: Command line option 'p' [from -purge] is not known.

Hi again Alan,

No, but reading the install page of FlatCAM it required sub programs that I could not find on liveCD. It's a thought. Maybe I should reinstall everything from scratch with 10.04 and build from there.

This is what the install page says:

Ubuntu

Tested on Ubuntu 12.04 LTS.

Install python-gi
Install libgtk-3-devel
Install python-shapely
Install numpy, scipy and matplotlib

sudo apt-get install python-gi
sudo apt-get install libgtk-3-devel
sudo apt-get install python-shapely
sudo apt-get install python-numpy python-scipy python-matplotlib

Sometime matplotlib might complain about missing libraries, particularly backend_gtk3agg. Then installing from source can fix this:

sudo apt-get install python-pip
sudo pip install matplotlib

This might complain about missing the distribute package. Install it (and try again):

easy_install -U distribute

If Shapely complains about missing libraries do:

sudo apt-get install libgeos-dev

One other thing that has come up is the need to install the Python development package in order for binaries to be able to compile. Do:

sudo apt-get install python-dev

Finally download and uncompress the Source, switch to the uncompressed directory and run:

python FlatCAM.py

Ach! Sorry about that. Bad info on the apt-get command. Try: "sudo apt-get purge rtai-modules-3.4.55-rtai-2_3.9-shabby-memleak", or "sudo dpkg --purge rtai-modules-3.4.55-rtai-2_3.9-shabby-memleak"

Mark

Thanks. I'll try it shortly. I'm building another machine right now for Linux only. The other computer has a dual boot with Ubuntu and Win 7.
Hence I'll try a new install. I'll be careful to install everything right. I have gained a lot of experience with this installation.

Thanks again.

Hi This Looks like you dont have real time Kernel build i recommend to cle an the build path and rebuild from scratch i had this error when i tried to build my own Kernel for a Mini Box ... the linuxcnc Forum was verry helpful Thomas

Gesendet von meinem SM-N9005 mit Tapatalk

To load linuxcnc to ubuntu 12.04 need rtai kernel see:
LinuxCNC Documentation Wiki: LinuxCNC On Ubuntu Precise

This will let you load a rtai kernel under 12.04 lts and 2.6... linuxcnc
