FW: [kaffe] bug report

[Thomas Keane]

Just wondering if anyone knows what the problem is below. I've attached
the output from gnu debugger. I cant get the "make check" to run
completely on my system.

Cheers,
thomas

That seemed to work - here's the output:

(gdb) run
Starting program: /root/kaffe/kaffe/kaffe/.libs/lt-kaffe-bin
at.dms.kjc.Main

Program received signal SIGSEGV, Segmentation fault.
start_this_sucker_on_a_new_frame () at jthread.c:1453
1453            if ((currentJThread->flags & THREAD_FLAGS_KILLED) != 0)
{
(gdb) where
#0  start_this_sucker_on_a_new_frame () at jthread.c:1453
#1  0x400af194 in jthread_create (pri=11 '\v',

    threadStackSize=0) at jthread.c:1533
(gdb)

Let me know if you need more information to figure out what the problem
is?

hmpf, should've remembered this ...

Kaffe clearly can't find java/lang/Object, since BUILD_ENVIRONMENT
only adds libraries/javalib/rt.jar to the classpath, which obviously
can't work, since you don't have that yet ...

If you modify the first line of the BUILD_ENVIRONMENT script to look
like this (assuming that /root/kaffe contains the sources):

BOOTCLASSPATH=${BOOTCLASSPATH}':'//root/kaffe/libraries/javalib/rt.jar':
'//root/kaffe/libraries/javalib/Klasses.jar.bootstrap; export
BOOTCLASSPATH

libraries/javalib/Klasses.jar.bootstrap is a precompiled jar archive
that contains the classes that are required to be able to run our
java compiler, kjc. So adding that one to the bootclasspath will
hopefully help (unless I forgot something else, that is).
