Re: ARM support

[Geert Bevin <gbevin at uwyn dot com>]

I tried compiling HelloWorld with the -static flag. When I run it, I get
a segmentation fault and the filesize (after stripping is still around
2MB).

/* start HelloWorld.java */
public class HelloWorld {
	public static void main(String [] args) {
		System.out.println("Hello");
	}
}
/* end HelloWorld.java */

Compiled with :
gcj --main=HelloWorld -static -o HelloWorld HelloWorld.java

Gives thus a segmentation fault. It works without static linking.

Any ideas?
