Building shared objects with gcj on osx

Fri Mar 4 17:44:00 GMT 2005

Hi,
I have a successful bootstrap build of 3.4.3 on os 10.2.8. When trying to 
build shared objects, I am receiving link errors:
bash-2.05a$ cat ./Test.java 
public class Test {
 public static void main (String [] argsv) {
 System.out.println ("Hello World");
 }
}
bash-2.05a$ gcj -o helloworld --main=Test Test.java
bash-2.05a$ ./helloworld
Hello World
bash-2.05a$ gcj -shared -o helloworld.so Test.java
/usr/bin/ld: Undefined symbols:
_main
___eprintf
collect2: ld returned 1 exit status
bash-2.05a$ 
The link error on "main" makes me suspicous - I presumed using -shared 
meant that no main was required?
I am fully aware I may be missing something obvious, and welcome any 
(helpful :) critism on how to get this working.... is it possible that 
weirdness is happening as OSX's /usr/bin/ld is used?
I have seen many messages on problems building native SWT/SwingWT on OSX, 
which I am attempting - the Makefile in SwingWT for SWT uses the same flags 
I have (although also tries to link in various jnilibs, in error I think). 
This is what has led me to the problem of getting -shareds working on 
osx.... any ideas?
Many TIA,
James
