Hi Don,

I'm sorry to see this isn't going the way you hoped. Probably you did
provide enough information. However, I'm working at some other parts
of the system, creating new infrastructure to (hopefully) be able to
fix some of the ansi compliance tests. This is tedious work and
distraction to your problem would probably leave me in a very sloppy
state. You'll understand that that's definitely undesirable.

Also, Ville has gone on holidays, meaning that we're halved in man power.

Unfortunately, that didn't happen. It's hard to recognise anything
from Java stack traces in ABCL: the code it generates is all called
"execute", meaning that there's very little we can actually see from
the trace, normally. The traces do help, but only after we gain more
insight into the problem.

Can you put on a download site somewhere the full directory you're
building from? I can have a go. It's possible that compile-file uses
undefined functions, but we'd expect those functions to be defined
elsewhere in the system. So, if they're not, that's alarming.

If I can download your build setup, I'll be able to diagnose your
problem the fastest (hopefully).

:-) Yes, some: I've become acquainted with the code structure for the
last 6 months quite a bit. However, the code in compile-file hasn't
been touched/studied much by me. That's no problem though: we can work
at it together.

Would it be possible to contact me through IRC somewhere during the
european evening? (9 or 10 pm CET?)

I'm usually hanging around on IRC a lot of time (but not all the time)
during the evening at #abcl on FreeNode
(irc://irc.freenode.net/#abcl).


Bye,

Erik.
