Hi Jari,
What kind of signal is it ? Could you run kaffe with '-vmdebug INIT' ?
I am thinking of two possibilities:
* stack boundary detection (which uses SEGV)
* GC handling (which uses a couple of signal to stop/start the VM).
Cheers,
Guilhem.

Hi,
I haven't progressed much. It would help *a lot* if someone who
understands how Kaffe works would tell who is supposed to send that
signal so it would be easier to find out why it is not done :)
I have also observed some variety in how Kaffe behaves. In some very rare
cases I have got it to print the HelloWorld message but usually it just
hangs before that.
Cheers,
Jari

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,

Hi,
I observed a few problems while compiling Kaffe cvs head:
******
Classpath configure fails due to missing X libraries although X and
GTK are disabled in Kaffe configure script:
# ./configure --prefix=/wrk/kaffe.intrp --build=i686-linux
--host=armv5b-softfloat-linux --enable-xscale --without-x
--disable-alsatest --disable-esdtest --disable-sound
--enable-pure-java-math --with-jikes=/opt/local/bin/jikes
--without-classpath-gtk-awt --without-kaffe-qt-awt --without-kaffe-x-awt
--with-threads=unix-pthreads --with-engine=intrp
...
checking for iconv declaration...
extern size_t iconv (iconv_t cd, char * *inbuf, size_t
*inbytesleft, char * *outbuf, size_t *outbytesleft);
checking for X... disabled
configure: error: GTK+ peers requested but no X library available
configure: error: /bin/sh './configure' failed for
libraries/javalib/external/classpath
I was able to fix this by doing a manual classpath configure (with
--disable-gtk-peer):
# cd libraries/javalib/external/classpath
# ./configure --prefix=/wrk/kaffe.intrp --build=i686-linux
--host=armv5b-softfloat-linux --enable-xscale --without-x
--disable-alsatest --disable-esdtest --disable-sound
--enable-pure-java-math --with-jikes=/opt/local/bin/jikes
--without-classpath-gtk-awt --without-kaffe-qt-awt --without-kaffe-x-awt
--with-threads=unix-pthreads --with-engine=intrp --enable-debug
--enable-xdebugging --disable-boehm-gc-configuration
build_alias=i686-linux host_alias=armv5b-softfloat-linux

--with-vm-classes=/wrk/kaffe-cvs-head/libraries/javalib/vmspecific
--cache-file=/dev/null --srcdir=. --disable-gtk-peer
******
The 2nd problem is that configure fails when cross compiling for
ARM/XScale:
...
checking for esd-config... /usr/bin/esd-config
checking for ESD - version >= 0.2.1... yes
Information: Using pure Java math library
checking which extensions to include...
checking if malloc debugging is wanted... no
checking pthread.h usability... yes
checking pthread.h presence... yes
checking for pthread.h... yes
checking for /proc/self/maps... configure: error: cannot check for file
existence when cross compiling
I was able to fix this with the patch below:
