Compilation/ld problem

Compilation/ld problem

[stephen]

Short version: 
	Compilation fails on a simple  program that uses
	BigIntegers.

I am using RedHat 6.0, out of the box, and I installed gcc with
the following RPMs from rufus.w3.org:

gcc-2.95.2-3.i386.rpm
gcc-java-2.95.2-3.i386.rpm
gcc-libgcj-2.95.2-3.i386.rpm
cpp-2.95.2-3.i386.rpm
binutils-2.9.5.0.22-4.i386.rpm

---> My BigInteger Hello World looks like this:

cut->--------
	import java.math.BigInteger;

	public class Hello {
	    public static void main(String[] args) {
		BigInteger test_integer = new BigInteger("1");

		System.out.println("Hello World!");
	  }
	}
cut->--------

	When I compile it like this:
		gcj -c Hello.java
		gcj --main=Hello -o Hello Hello.o
	I get the following errors:

Hello.o: In function `Hello::main(JArray<java::lang::String *> *)':
/home/stephen/bin/src/Java/Mars_II/Mars_II_New/Hello.java:5: undefined
reference to `_CL_Q34java4math10BigInteger'
/home/stephen/bin/src/Java/Mars_II/Mars_II_New/Hello.java:5: undefined
reference to `java::math::BigInteger::BigInteger(java::lang::String *)'
collect2: ld returned 1 exit status

	Is there a way to fix this?

Thanks,
Steve

libgcj doesn't have a BigInteger implementation yet.  However, it will
very soon - just watch the java-patches list.
