That's what I thought.

Just a tiny bit.

As far as my understanding goes, I'd first create a shared library with
something like this:

gcj -fPIC /usr/share/java/scala-library.jar -shared -o scala-library.so

and then when compiling a Scala program, I'd say:

gcj --classpath=.:/usr/share/java/scala-library.jar HelloWorld*.class
scala-library.so

But I haven't managed to create the shared library. When I attempt to
run the first command, I get something like:

scala/collection/immutable/StringLike.scala: In class
'scala.collection.immutable.StringLike$class':
scala/collection/immutable/StringLike.scala: In method
'scala.collection.immutable.StringLike
$class.replaceAllLiterally(scala.collection.immutable.StringLike,java.lang.String,java.lang.String)':

		 ...
                 from scala/AnyVal.scala:7,
                 from <built-in>:3:

Can you please tell me how to get the shared library?
