device (Maemo - Chinook). I'm well aware of jalimo [1] but that doesn't
ship with a compiler. I also noticed there is ecj available for

debian-lenny, but that's not installable due to conflicts with osso
packages.

java 1.5 code.

VM

slow (as expected).

details of cross-compilation: My efforts of compiling gcc/gcj in
scratchbox (one and two) failed so far at different stages of the gcc
building process.

you maemo devs: Am I missing something fundamental here :)?

Hi,

last week Robert Schuster and I worked on this topic in jalimo. I got a
openjdk compiled and run it on n810.
Unfornatly is not stable yet. I tested
some graphical Applications on the n810 and most crashes,
when it comes to awt and images.

For now you can use cacao with classpath. All you need is to read this

Bye Henning
