It answers "Cannot create autom4te.cache No such file or directory" . Strangely in the autogen.sh the file is called auto4mte.cache

Always the same 2.6.32-122-rtai ..... 27. Juli 2012. Its strange that I can install nearly half a GiB of software without an error message and after a newstart it happens nothing.

The first step is to download and install an appropriate preemt-rt kernel (and boot from same)
you will not have much luck running the uspace version of linuxcnc without it

I have tried to install the RT preempt from the first page. Without any success. Maybe I must start it with any special inputs, but if you have no start-up-message, how can I run the new compiled version.
I tried the download here from the download section, first the 2nd latest, then the latest, but each version don't can be updated with RT preempt. But the RTAI is as well a RT system. Why can't I use this, what I have read, the System should be as least as good as the RT preemp. Eventually I should try to use an outdated version.
I know nothing about linux special commands, maybe if i type ctrl-S or similiar at start-up I get a startscreen. But If I don't know the command, its nearly impossible to type in that correct.

What OS version and distribution are you running?
You will need to setup grub to boot the preemt-rt kernel
Holding the shift key when booting will invoke the grub boot menu (not sure if this is universal)
The uspace version of linuxcnc that hm2_eth uses requires a Preemt-RT kernel

Now I have installed the 5th different Ubuntu version. In each case I can't install the RT Preempt. I fear, I use a board that I can't use with this. Today I will try an old s775 Board that I have sent to retirement. I hope I can install the supplement on this board. If yes, I will try to run it on the newer board, that is (I hope) a good part faster.

here I think are easiest steps to run 7i80:
1. Install debian www.linuxcnc.org/binary.hybrid.iso
2. install packages3. Install linuxcnc sources from git: linuxcnc.org/docs/2.5/html/code/Contribu...nc_official_git_repo
4. build it and run it using my instructions few messages ago.
1. Install debian www.linuxcnc.org/binary.hybrid.iso

Also if you use the latest LinuxCNC ISO (Debian Wheezy)
www.linuxcnc.org/index.php/english/download
There's a pre-built Debian Preemt-RT kernel package available:
sudo apt-get install linux-image-3.2.0-4-rt-amd64
You still need to install/run linuxcnc master (2.7)
If you use Wheezy, there's a pre-built linuxcnc master (2.7) binary for Preemt-RT here:
buildbot.linuxcnc.org/
(master-rtpreempt)
