NewBie question: Segmentation faults

Sat Apr 1 00:00:00 GMT 2000

This is the type of HelloWorld:
$ file HelloWorld
HelloWorld: ELF 32-bit MSB executable, PowerPC or cisco 4500, version 1,
dynamically linked (uses shared libs), not stripped
but it seems that gdb can't execute it
> Using gdb:
>> $ gcj -g --main=HelloWorld -o HelloWorld HelloWorld.java
> $ gdb ./HelloWorld
> "run"
> "bt" when it crashes. Send us the output.
>> Is suspect your problem is the garbage collector. You may want to try a newer
> libgcj snapshot, which has a new gc version and some PPC fixes.

$ gdb ./HelloWorld
GNU gdb 4.18
...
(gdb) run
Starting program: /home/adenis/java/./HelloWorld
Don't know how to run. Try "help target".
(gdb)
I compiled gcc 2.95.2 and I tried to compile libgcj-snapshot-2000年02月18日:
first it was complaining that java-array.h didn't exist in some .h files that I
couldn't find. So I just linked libjava/include/java-array.h to
libjava/gcj/array.h
It then seemed to compile fine but at the last link for libgcj.so I got:

Things don't seem to be working overly well for me :)
