[Kaffe] memset in javacall.c on mips platform

[ColinYen]

Hi,All:

I run kaffe(1.1.X_CVS_20050930) on mips platform.
If Kaffe(intrp) run memset(call.args, 0,
(METHOD_NARGS(meth)+engine_reservedArgs(meth)+2)*(sizeof(jvalue)+2));
in KaffeVM_callMethodA in kaffe/kaffevm/javacall.c, system get
error message.
I find Can't access bad memory exception.

message:
Internal error: caught an unexpected exception.
Please check your CLASSPATH and your installation.
java/lang/NullPointerException
  at java.lang.Object.getClass (Object.java:331)
  at java.security.Permissions.add (Permissions.java:112)

But I remove statement memset(call.args, 0,
(METHOD_NARGS(meth)+engine_reservedArgs(meth)+2)*(sizeof(jvalue)+2));
Kaffe can run correctly.

I don't know what's happen? Please help me.

Thank a lot.

Colin Yen

[kaffe] Using Kaffe with Nano-X engine

[Gianluca Moro]

Hi all,

I'm trying to compile Kaffe on a MIPS embedded
system with Nano-X as graphical library.

The compilation was done with

./configure --with-jikes=no --with-engine=intrp 
--enable-pure-java-math --without-esd --without-kaffe-x-awt
--with-kaffe-nanox-awt --with-jikes=no
--with-rt-jar=/home/AMDgiammy/kaffe-1.1.6/libraries/javalib/rt.jar
--without-classpath-gtk-awt

Now I correctly execute java programs with textual output,
but when I try a graphical Hello World test,
I get:
java.awt.AWTError: Cannot load AWT toolkit:
gnu.java.awt.peer.gtk.GtkToolkit

It seems kaffe try to use X (non present), but I have
not found where to tell it to use Nano-X!

Can someone give me a pointer to some configuration or steps
I must accomplish 
to make kaffe execute graphical programs on Nano-X?

thanx
giammy

Ciao gianluca,

try kaffe -Xkaffe-nanox-awt HelloWorld. :)

I'll add that to the documentation in FAQ/FAQ.awt. Thanks for the bug
report.

ciao,
