What Can I do to port JVM on MPC?

Hi everyone,
I'm running linux 2.4.22 on my MPC8272ADS board using Metrowerks BSP
and I need JVM on it to go further in my project.
But it's very hard to find any clue for porting it.
Any advice or starting point?

Thanks.

peter

What Can I do to port JVM on MPC?

[Dick Hollenbeck]

There is a JVM that is part of GCC called libgcj.  It differs from Sun's 
JVM in that is uses "ahead of time compilation" of the Java code all the 
way to machine code.  Whereas Sun's JVM runs on "java bytecode" and at 
runtime compiles this bytecode to machine code "just in time".

Unfortunately the build system for libgcj is abysmal and shameful, and 
the garbage collector will pause the process that runs it about 55 msecs 
every so often.  So aside from the build system and the GC, libgcj is 
excellent work.


I would start with libgcj.

It should be your path of best investment.


Been there, done that.
