EMC for Feisty Fawn

[nancygal]

I just downloaded and installed Ubuntu 7.04 (Feisty Fawn). It is the only version of Ubuntu that I have been able to connect to the internet with on this computer. I would like to play with EMC on this computer but it is only supported with Ubuntu 6.06 (Dapper Drake). Any ideas on how to use EMC with 7.04?

Thanks

Did you disable ipv6 on you 6.06 version ?

Took a little searching but I got there in the end.

For details, have a look here :

The browsing was easy, getting synaptic to work took a little more effort, but was nice once it was all going. I was impressed I could get a browser working with a live version running, even before any HDD install.

I liked it so much I am in the process of upgrading all home PC's to Ubuntu, I had tried Linux previously a few years back but it wasn't really "there" for desktop use for me, now I am quite happy with it and intend to use it exclusively.

Good Luck!!!

Russell.

I would prefer to use 7.04 as 6.06 didn't work on this computer. This system has a Intel Core 2 Duo processor. An old Dell system I have works with 6.06 but it is not connected to anything.

I have just installed 7.04, and it runs great on my system. That being said, I don't really see why 6.06 couldn't be made to work with your computer. Perhaps dualboot with 7.04 if not doing CNC stuff..

I got EMC to run just fine on Feisty.

How?

Did you just try to install the precompiled package?

I compiled the app itself from source. Theres a ton of prerequisites you must install first, and it appears that the build from source instructions for 6.10 work for this too. The wiki over at linuxcnc.org has a good article on it, but the easiest way to bring your system up to speed on the prerequisites is running apt-get, here is the entire command:

 $ sudo apt-get install cvs build-essential libgtk2.0-dev libgnomeprintui2.2-dev \
    tk8.4-dev python2.4-dev python-numarray-ext python2.4-imaging \
    libpth-dev bwidget xlibmesa-gl-dev libgl1-mesa-dev libglu-dev \
    libreadline-dev libxmu-dev python-tk

Then you just download the source code from CVS, compile it, and run it. If you need asistance with complications, just let me know. There were a couple of tweaks I had to make, and I don't remember what they were offhand (it was 2 AM), but I got it to run.

With this - I don't think you have installed the realtime kernel. I think your just running emc in sim mode.

You can try the rtai latency test

sudo mkdir /dev/rtf; sudo mknod /dev/rtf/3 c 150 3;
sudo mknod /dev/rtf3 c 150 3;
cd /usr/realtime*/testsuite/kern/latency; ./run

should look like this.

ubuntu:/usr/realtime-2.6.12-magma/testsuite/kern/latency$ ./run

* Type ^C to stop this application.

btw - the reason the emc2 group chose dapper.

2.1. Why aren't there packages for Ubuntu 6.10 "Edgy Eft"? We have chosen to use 6.06 because it's a "long term support" (LTS) release. If you use it, you can be sure of support and security fixes from the Ubuntu team for 3-5 years. However, we would be happy to accept and host packages for 6.10 if a user/developer of emc2 wishes to contribute them.

Samco....I'm quite sure my installation is the realtime kernel :-)

Anyway, I can go home and do it from scratch again, and do a step by step with 7.04 if youd like?? It's running on a test box, so it really wouldn't be a big deal if I did.

[samco]

That would be great - an addition to the wiki would be even better

thanks

I will make it so.
