That will work - also jepler wrote a nice gui latency test program. You
can run it from terminal by issuing 'latency-test'.

I started downloading now, but I already have a question.
On the Live CD, and then after installing, is there a realtine
performance test script ready?
In the old (2.1 EMD2 distro) I used a file with a script like this one:
/QUOTE BELOW
#!/bin/sh
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
/QUOTE HAS ENDED
If it is not there, may you please schedule adding it right on the
desktop? It will make testing the usefulness of different platforms
much easier and faster. As for the above script, I fould in on a
Windows drive, not sure if it is the same I use on linux...
Thanks.

As most of you probably know, the latest version of Ubuntu has been
released: Ubuntu 8.04 Hardy Heron.
(http://www.ubuntu.com/news/ubuntu-8.04-lts-desktop)
As it is another LTS release (3 year support on the Desktop version - which
we use), we consider that it's important to have emc2 packages (along with
the needed infrastructure: patched kernel, rtai, etc) for it. Consiquently
we have built packages, a repository for them, and a LiveCD for easy testing
and install.
== Disclaimer ==
Before describing download and install procedures I would like to point out
that at this point the packages have been tested by a semi-large number of
people, and only a couple problems have been reported so far (on some
hardware where it doesn't work at all). Therefore I do not encourage at this
point to replace a working dapper install with the new hardy version. Dapper
is still supported until 2009, and as long as it's supported we will be
building emc2 packages for it. If you want to take part in the ongoing
testing phase for hardy, please read on; otherwise wait a couple days/weeks?
until we announce it fully released.
== Installing/testing procedures: ==
1. starting with a LiveCD (provides means for testing only, or even install
if wanted)
Step 1: Download the iso from:
http://www.linuxcnc.org/hardy/ubuntu-8.04-desktop-emc2-aj07-i386.iso (note:
this URL might change in the future, reference
http://www.linuxcnc.org/hardy/livecd.errata for the latest name, and for a
description of known problems).
Step 2: Check the MD5SUM (note: also mentioned in the livecd.errata, the
latest one is: 91c5abb84386091e0ff056e9ebc40fdb)
Step 3: burn the image
Step 4: boot it on as many PCs as possible (Note: the Hardy Heron LiveCD
needs at least 384MB RAM to boot in Live mode, or 256MB for installing, an
existing swap partition on the harddrive will be picked up, so it might be
possible to boot the Live version on systems with less memory).
Step 5: report problems encountered
2. starting with an existing Ubuntu 8.04 Hardy Heron install
Step 1: Install Ubuntu 8.04
Step 2: Once you have installed Ubuntu , get the install script from here:
http://www.linuxcnc.org/hardy/emc2-install.sh , choose "Save to Disk" and
click OK.
Step 3: Now an emc2-install.sh icon will appear on your Desktop. Right-click
that icon, select Properties. Go to the Permissions tab and check the box
for Owner: Execute. Close the Properties window.
Step 4: Now double-click the emc2-install.sh icon, and select "Run in
Terminal". A terminal will appear and you will be asked for your password.
Step 5: When the installation asks if you are sure you want to install the
EMC2 packages, hit Enter to accept. Now just allow the install to finish.
Step 6: When it is done, you must reboot (System > Log Out > Restart the
Computer) - once you have rebooted you can run EMC2 by selecting it on the
Applications > CNC menu.
Step 7: If you aren't ready to set up a machine configuration, try the
sim-AXIS configuration; it runs a "simulated machine" that requires no
attached hardware.
Step 8: If you experience problems with things that used to work on the
default hardy, but don't after installing emc2, chances are you need one of
the special modules. (you can install them with: sudo apt-get install
linux-ubuntu-modules-hardy-rtai).
== Reporting problems & getting help ==
Reporting issues/problems/nags/ideas for improvements or anything else, can
be done via email (on this list, or directly to me) or via IRC (#emc-devel
on irc.freenode.net). I will try to be available to a very large extent
during the next couple of days.
Thanks for your patience, and for all the help to make it another great
release.
Best regards,
Alex Joni
