latency test. If I am not then the RTAI test suite deletes /dev/rtf3 and
then complains that it is missing.

Thanks for the suggestion. I gave it a try:

I then ran the script to create the devices. Unfortunately "halcmd help"

Jeff,
Does the following script do the same thing?

The following emc2.rules file, which is installed when you install a
.deb of emc2 (but not by 'make install), makes the rtai_shm device
accessible to all users:
~/emc2-src/debian/extras-Ubuntu-6.06/etc/udev/rules.d$ cat emc2.rules
KERNEL=="RTAI_SHM" SYMLINK=="rtai_shm" MODE="0666"

Another thought - does permissions need to be set on a file somewhere to
allow the shared memory to work for all users? I did:
./configure
make
make install
I didn't run make setuid. Is that still needed for a make install?

A little bit more info:
When this function is called:
retval = rtapi_shmem_getptr(mem_id, &mem);
mem_id = 1. Upon return, mem = 0x0 and retval = 0.
So it seems the shared memory system doesn't work properly as mem should
never be set to zero. This is pretty much the limit of my debugging

Thanks. It seg faults at line 2350 in hal_lib.c:

It appears that hal_data is NULL at this point. Here is the call stack:

A system call trace (produced by using "strace") or a backtrace at the
time of the segmentation fault (produced using "gdb") would be helpful
in pinpointing the location of the problem.
You can find information how to use these utilities on many pages on the

Jeff,
Thanks - I will give that a try. I think a shared memory error was in
the mix.
I also need to manually create the application menu entries.
/usr/local/bin/emc is obvious. Are there any other executables that
users should be able to run from the menu?
Once I have this set up I will publish
EMC 2.1.x is unlikely to work on Ubuntu 7.10. However, the development

versions of Ubuntu.
On Ubuntu 7.10 the default amount of "locked memory" for regular users
is too low. You can fix that problem by adding the line

Update - I can get EMC2 CVS HEAD to start up with no errors if I start
it as root. Otherwise it fails at the insmod stage. I guess regular
users don't have permission to do this.
So how do I solve this problem?

Subject: Problems Compil
Hi! For various reasons I have chosen to build my own kernel and compile
EMC2. I'm nearly there but stumbling at the last stage.
I have patched a vanilla 2.6.22 kernel with RTAI. My PC boot and runs
normally and I can execute all the RTAI scripts in the testsuite. I am
using Ubuntu 7.10.
