RE: error

[Fred Wan]

Hi Paul, thanks for your reply. Just at the moment it came in, I was
compiling ExperBug in Objective C, and while doing so I seem to have fixed
most of the problem. I didn't even notice that until I was replying to you
with a rather extensive report... :) As you may remember, I have been using
and installing swarm for a couple of years (about a year ago we had an
elaborate discussion about nesting swarms), and the 'easier' problems like
missing or incorrect paths do usually nog pose a problem anymore. Also, I
leave the system I'm developing swarm sims on alone as much as I can,
exactly to prevent messing up the swarm installation.

Therefore, I still don't understand how this problem could have occurred
overnight (there were no earthquakes and no thunderstorms). Anyway, because
of the output generated by gdb, java was working OK, and the fact that the
sim crashed at a very early stage (swarm initialization), it was not my own
code that was the problem. The question was whether it was something in the
swarm installation or something in my W2K system. I could find no clues for
either cause. While compiling ExperBug in Objective C I had to make some
fixes such as modifying makefiles and copying missing files. It's always
hard to retrace your steps after such an elaborate operation, but I'm sure
copying some of the following files from older swarm installations to
Swarm-2.2/lib was essential:

libshell32.a
libkernel32.a
libuser32.a
libgdi32.a
libadvapi32.a

Swarm still generates odd messages it didn't before, but most of the sims
and demo's work again now.

Thanks for your help,
Fred.

PS Since Swarm has been phased out of our research group (and I'm the only
one who's stubborn enough to go on with it), there is not much enthousiasm
to join the SDG, but I'll make it a demand with my future employer... :)

Below are some fragments from the original message I intended to send, maybe
there's someone who can benefit from it.

Messages from experBug in Objective C (even after compiling it still didn't
work, so the copying was certainly not the only thing) for an OLD version of
swarm:

Then I tried it with the latest version (pretest 6). Now the GUI appeared
and the sim seemed to start, but then crashed with the following message:

At least this seems to be a meaningful message. Then I installed the swarm
demos package which should bypass any errors in my own swarm installation.
Some of them worked, some didn't. Here's which did and didn't:

antsort NO
arborgames NO
asm YES
bank YES
dynamicGraph YES
heatBugs YES
market YES
moustrap YES
sss YES
tipsyBugs YES
turmites YES
vila4 NO

...

I both use Visual Cafe as IDE and debug with that most of the time. If I set
a breakpoint on Global.env.initSwarm(...) and I step into that line it
brings me to a Visual Cafe piece of code called 'ClassLoader.java', if I
then continue the crash occurs. This is the output from gdb:
