Hello!
I'm currently trying to compile kaffe-1.0.7 on a PPC running LynxOS
4.0.0.
In 'config/powerpc' I created the directory lynxos containing the
following
files :
'md.c' -> copy from powerpc/linux
'md.h' -> copy from powerpc/linux, but defining SP_OFFSET to be 57 (I
used
the sp_offset.c program once posted in this group to figure
out the
SP_OFFSET value)
'config.frag' -> defining :
Khost_cpu=powerpc
Khost_os=lynxos
CFLAGS="$CFLAGS -fsigned-char -mpowerpc"
So far so good. The configure script (parameters: --host=ppc-elf-lynxos)
and the following make, make install succeeded.
After running kaffe with some simple "HelloWorld" program. I'm getting
a "SIGVTALRM, Virtual timer expired".
Using the gdb and some debug output I got the following :

The output of other gdb runs is truncated on arbitary places. It seems
that the SIGVTALRM is not catched inside the kaffevm ?
Any suggestions ?
Thanks
