Try the run-in-place method:
(from the top of your checkout)
for run-in-place you need scripts/realtime start

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

I didn't run make setuid. Is that still needed for a make install?

EMC 2.1.x is unlikely to work on Ubuntu 7.10. However, the development
version has been improved in various ways for compatability with newer
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
hard
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
I have narrowed the problem down to this:

Use 'help command' for more details about each command

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
internet.

Thanks. It seg faults at line 2350 in hal_lib.c:
static int init_hal_data(void)
{
/* has the block already been initialized? */
if (hal_data-version != 0) {
It appears that hal_data is NULL at this point. Here is the call stack:
hal/utils/halcmd_main.c:195 (main)
hal/utils/halcmd.c:109
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?
thanks for the help! Andy
