Hi Fabio,
I'll answer this properly off list. From the looks of it, you have a configuration problem. The VM can't find the JamVM versions of the VM classes (VMThread, etc.) and has picked up the default Classpath version of VMThread, which doesn't have the vmData field. It expects to find them in /usr/local/share/jamvm. If you put them somewhere else you need to override the default location at build time.
Rob.

Hi all my name is Fabio Antonini and since the last week I'm evaluating classpath with jamvm. I'm trying to cross-compile the classpath/jamvm for a ppc405 from a i686 linux based host. When I run the jamvm on a simple hello world class file I receive the following message
sh-2.04# /usr/local/bin/jamvm -verbose -verbosegc -noasyncgc hello [Linking class java/lang/Object] [Linking class java/io/Serializable] [Loaded /usr/local/classpath/share/classpath/java/lang/Class.class] [Linking class java/lang/Class] [Loaded /usr/local/classpath/share/classpath/java/io/Serializable.class] [Loaded /usr/local/classpath/share/classpath/java/lang/Class.class] [Loaded /usr/local/classpath/share/classpath/java/lang/Object.class] [Loaded /usr/local/classpath/share/classpath/java/lang/Runnable.class] [Linking class java/lang/Runnable] [Loaded /usr/local/classpath/share/classpath/java/lang/Thread.class] [Linking class java/lang/Thread] [Loaded /usr/local/classpath/share/classpath/java/lang/VMThread.class] [Linking class java/lang/VMThread] Error initialising VM (initialiseMainThread
Digging into the code with lots of printf I've seen that the problem arises inside the initialiseMainThread function when the VM tries to read some parameters from the class
thread_class = findSystemClass0("java/lang/Thread");vmThread = findField(thread_class, "vmThread", "Ljava/lang/VMThread;"); daemon = findField(thread_class, "daemon", "Z"); name = findField(thread_class, "name", "Ljava/lang/String;"); group = findField(thread_class, "group", "Ljava/lang/ThreadGroup;"); priority = findField(thread_class, "priority", "I");
run = findMethod(thread_class, "run", "()V");
vmthread_class = findSystemClass0("java/lang/VMThread");
thread = findField(vmthread_class, "thread", "Ljava/lang/Thread;");
vmData = findField(vmthread_class, "vmData", "I");
printf("Hello from Fabio\n");
/* findField and findMethod do not throw an exception... */
if((vmData == NULL) || (run == NULL) || (daemon == NULL) || (name == NULL)
||
(group == NULL) || (priority == NULL) || (vmThread == NULL) || (thread
== NULL))Any idea about this? Could this be related to the different endianess between the target and host processors? Any help will be appreciated. Thank you in advance Fabio
