[developers] Logon on Ubuntu 10.04

[C.J. Adams-Collier KF7BMP]

In that case, I recommend attaching to the lui process with strace or
ltrace after it launches, but before you ask to show a feature
structure.

After launching, find the PID of lui with

$ ps auwx | grep lui

when you have the PID, you can pass it to ltrace with

$ ltrace -p <PID>

This should print the library function entrance/exit trace as the
program runs.  You will be able to tell which of the library functions
was being executed when the crash happened, and hopefully will be able
to proceed from there.  You can do the same with strace, but the output
will probably end up mentioning ldload() as the culprit, which will
probably not help to clarify anything.

I don't have logon installed on my system at this time, and I don't have
a lucid virtual machine handy, but I have been meaning to put one
together and could probably be convinced to do so if this doesn't help
to solve the problem.

Cheers,

C.J.

I don't get any complaint about shared object files with yzlui, but as I mentioned, it crashes when asked to show a feature structure, unfortunately without any visible complaint.

Unfortunately, the file /tmp/yzlui.debug.danf does not supply any clue about what goes wrong with AVMs.  All I see is the following Lisp message (the same one that pangolui produces when it crashes):
