[kaffe] Compile problems

[Rafael Teixeira]

Hi Jari and Kaffe-List:

I'm also stuck with Kaffe stopping on startup on my XScale (IXP42x)
hardware. To add some more info we've tried with JamVM and SableVM,
and similar behaviour occurs, our next try is to use Mono with IKVM,
to see if we can get a single VM to startup our java firmware in the
XScale.

By tracing a bit, sure things look like your unanswered post on Signal
Waiting was in the right track, but with JamVM we are sometimes able
to get a simple "Hello World" to work, and sometimes it also hangs.

Jari, Have you been able to go further?

Thanks for any information, and we will be glad to share what we find
on our quest to make Kaffe work on XScale.


Regards,
