ld error with gcj cross-compiler

[Aran Benner]

Hi,

After much efford, I've finally managed to set up GCC 3.1 as a
cross-compiler for a M68k-elf system (a M5272 system running uClinux, to be
precise). 

I've copied a test program, HelloWorld.java:

public class HelloWorld {
   public static void main(String [] args) {
      System.out.println("Hello World!");
   }
}

I've compiled and ran this program succesfully with a GCJ 3.0.4 native
compiler, but now, trying to compile it with a GCJ 3.1 cross-compiler I get
an error. Actually, I'm not exactly sure what compile options I have to
give, but I've tried multiple combinations, each with the same result. Here
is the most basic one:

[aran]# /usr/local/bin/m68k-elf-gcj -m5200 --main=HelloWorld -o HelloWorld
HelloWorld.java -v

Any help would be greatly appreciated.
