Title: Anyone Ported Jamvm?
Post by: marvi on November 24, 2005, 07:51:22 am

JamVM looks like a nice and small JVM, suitable for Zaurus. It's already ported to ARM so I guess it should be fairly easy for a Zaurus devloper to port it?

JamVM is a new Java Virtual Machine which conforms to the JVM specification version 2 (blue book). In comparison to most other VM's (free and commercial) it is extremely small, with a stripped executable on PowerPC of only ~135K, and Intel 100K. However, unlike other small VMs (e.g. KVM) it is designed to support the full specification, and includes support for object finalisation, Soft/Weak/Phantom References, the Java Native Interface (JNI) and the Reflection API.

And:

ARM: ported and tested on the iPAQ running Linux (3950, with xscale PXA250 processor, though it should work on StrongARM). Little and Big Endian machines are supported, and soft/kernel FP emulation.

Ok, great.

Will it work on Sharp ROM too?

I guess not.

Maybe using X/Qt, but I have no experience with it.

Hi,
When using JamVM with GNU Classpath requirements are GTK+ 2 and gdk-pixbuf

It doesn't work on Sharp ROM. libgtkpeer.so complains about not finding the log symbol

finally found the culprit causing the crash

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=23040 (http://gcc.gnu.org/bugzilla/show_bug.cgi?id=23040)

it's a new bug and not fixed yet.

so now I got jamvm 1.4.2 with classpath 0.20 working under Sharp ROM but without cairo and xmlj support

What does the lack of cairo and xmlj in pdaxrom prevent from working, in general terms?

it just means no jedit but i got jedit running with blackdown jvm anyway.
also no cairo means no 2D and vector graphics
no xmlj means xml parsing will be slow++

Thanks.  So, basically things are moving in the right direction, but not quite there for firefox plugins.

Any luck with gplflash and mplayer plugin on pdaxqt/firefox?
