[kaffe] A question about "JNI_OnLoad"

[embstudy at eyou.com]

Hello Guilhem

in your last letter to me, you said:
*********************************************************************
Hi !
Thank you for the detailed testings. As HelloWorldApp is working, we can 
eliminate sysdepCallMethod. However, I don't see how qtopia may 
interfere in initProperties. Is it possible for you to have gdb precise 
stacktrace of the point where it gets a NPE in the native code ? I don't 
see why it should be a setProperty call, but maybe something more system 
dependent.
Cheers,
Guilhem.
*********************************************************************

Today, I tried to crosscompiled gdb-5.3 successfully.  :0)
But I am in fact a tyro to gdb, and I don't know how to figure out
the precise point of the NPE.
Maybe you could give me some suggestions?
I just do what I can :)
-------------------------------------------
I started the qtopia and opened the embeddedkonsole,
where I did as this:
# export KAFFE_DEBUG=gdb
# javac
------------------------------------------------------------------------------
-
(gdb) run
Starting program: /cvs/xscale/jre/bin/kaffe-bin at.dms.kjc.Main

#6  0x40217e10 in __libc_start_main () from /lib/libc.so.6
------------------------------------------------------------------------------


I can deduced nothing useful for me from the above info. And I think it didn't

disclosed the fact precisely.
BTW(By the way), I didn't enable the xdebugging in this compiled version of
kaffe for the sake of some compiled errors. Is that necessary for me?
Waiting for your help... :P)

cheers,
Saw
