Regarding frame pointer:
Edouard's porting kaffe document says:
Some platforms need to setup Frame-Pointer register
when creating a new thread stack. In this case you
must provide his offset FP_OFFSET into jmp_env.
Macros SP_OFFSET and FP_OFFSET should be defined in
file config/$Khost_cpu/$Kost_os/md.h.
Regarding classpath:
Would adding "." to the classpath in respective
makefiles help?
best regards,
