[Soot-list] Howto generate a CallGraph?

[bq chan]

Sorry to bother you again. I was really frustrated:(   I still have trouble
with generating CallGraphs .

Would you please give me a trivial example to show me how to generate the
CallGraph please.

the tutorial examples in
"~/soot-2.3.0/tutorial/guide/examples/call_graph/src/ " doesn't work for
me.



[root at localhost testers]# java -Xms256m -Xmx512m -Xss128m
dk.brics.soot.callgraphs.CallGraphExample -w testers/CallGraphs
[Call Graph] For information on where the call graph may be incomplete, use
the verbose option to the cg phase.

I have also tried the following code, but:

[cbq at localhost cg]$ java -Xms512m -Xmx1024m -Xss128m  CgMain -w  CgMain

No main class given. Inferred 'CgMain' as main class.

public class CgBody extends SceneTransformer
{
    private static CgBody instance;
    private CgBody() {}
    public static CgBody v()
    {
    if(instance == null)
        instance = new CgBody ();
    return instance;
    }

    protected void internalTransform ( String phaseName, Map options)

    {
    CallGraph cg =Scene.v().getCallGraph();
    G.v().out.println(cg);
    G.v().out.println("size"+cg.size());

    SootMethod src = Scene.v().getMainMethod();

    Iterator targets = new Targets(cg.edgesOutOf(src));
        while (targets.hasNext())
                {
            SootMethod tgt = (SootMethod)targets.next();
            System.out.println(src + " may call " + tgt);
        }


    }

}



public class CgMain
{
    public static void main(String[] args)
    {
    Pack pack=PackManager.v().getPack("wjtp");
    pack.add(new Transform("wjtp.cgtrans",CgBody.v()));
    soot.Main.main(args);

    }

}
