Re: [kaffe] kaffe awt and thread management on MIPS
Recently, I am working on JIT and XScale series, and I have commited some Nano-X related fixes into cvs repository. Could you please take it a try with cvs head? However, thank you for sending and sharing the previous information about Nano-X AWT backend and threading on MIPS, which is another great platform Kaffe should support. Hi Jim, I found some problems with the last version of Kaffe (1.1.6), in particular, the problem I found was: java.lang.ExceptionInInitializerError caused by: java.lang.NullPointerException at java.awt.Toolkit.fntInitFont (Toolkit.java:native) Looking at the code, it seems that the function which initializa the fonts return an id (an integer, i think) while the nativeData field is declared as Pointer. I think that this gives the exception. I checked kaffe-1.1.5 and I saw tha nativeData was declared as Ptr: compiling kaffe-1.1.5 and following the same steps I followed for 1.1.6, I got a runnable kaffe which gave no exceptions. I'll check, as soon as I get a working kaffe, the CVS head, but I think I'll need to change the Pointer declaration to test it :-( Anyway, thans so far for kaffe team support bye giammy -- Gianluca Moro Visit http://ilpinguino.altervista.org/ [EMAIL PROTECTED] MyBlog http://blog.libero.it/giangiammy/ __ Yahoo!

[kaffe] kaffe awt and thread management
I'm testing kaffe in MIPS platform with Nano-X: my test program open a windows, but do not show anything in it (while the same program on Pc show the inner objects) Tracing the code, I see that the function kaffe-1.1.5/libraries/javalib/java/lang/VMThread.java:sleep() is calling the function vt.wait with parameter 250ms, but it never returns. From what I understand, that function calls /kaffe-1.1.5/libraries/clib/native/Object.c:java_lang_VMObject_wait, whose debugging message gives me 0x10276010 (0x102622f8) waiting for 0x102622f8, 0 It seems that here the parameter (250ms) became 0: do I understand correctly? And if so, why (and where) the 250 value was lost? (kaffe is ocmpiled with unix-jthreads) thanks giammy -- Gianluca Moro Visit http://ilpinguino.altervista.org/ [EMAIL PROTECTED] MyBlog http://blog.libero.it/giangiammy/ __ Yahoo!

Re: [kaffe] kaffe awt and thread management on MIPS
Hi, I compiled my kaffe on mips with the following ./configure --with-jikes=no --with-engine=intrp --enable-pure-java-math --without-esd --without-kaffe-x-awt --with-kaffe-nanox-awt --with-rt-jar=/home/AMDgiammy/kaffe-1.1.5/libraries/javalib/rt.jar --without-classpath-gtk-awt --enable-debug --with-nanox-include=/usr/include/microwin --with-nanox-library=/usr/lib --with-threads=unix-jthreads perhaps the problem on threads in the MIPS porting can be solved with ad appropriate configuration of ./configure or CFLAGS or so: I found in the web, for example setenv CFLAGS -G 0 -mno-abicalls -fno-pic -mcpu=r4300 -mips2 but such a configuration fails in the configuration, while finding the size of a void *. Is there someone who compiled a more recent version of kaffe (I'm working on 1.1.5), and have a working configuration? (I doubt to be able to find a bug on the config/mips/* side :-) thanks giammy --- Dalibor Topic [EMAIL PROTECTED] wrote: Gianluca Moro wrote: I'm testing kaffe in MIPS platform with Nano-X: my test program open a windows, but do not show anything in it (while the same program on Pc show the inner objects) Tracing the code, I see that the function kaffe-1.1.5/libraries/javalib/java/lang/VMThread.java:sleep() is calling the function vt.wait with parameter 250ms, but it never returns.

That might suggest there is a bug in the config/mips/* implementation of the ABI, or in the JNI code. You can try bulding Kaffe with libffi, which comes from gcc, and is in general up to date with different ABI changes. If it's a bug in the JNI code, you could look at fixing the compiler warnings in kaffe/kaffevm/jni* directory. cheers, dalibor topic -- Gianluca Moro Visit http://ilpinguino.altervista.org/ [EMAIL PROTECTED] MyBlog http://blog.libero.it/giangiammy/ __ Yahoo!

Re: [kaffe] kaffe awt and thread management (and libffi)
You can try bulding Kaffe with libffi, which comes from gcc, and is just looking, but it seems that libffi has not been ported to mips architecture :-( anyway, thanks giammy -- Gianluca Moro Visit http://ilpinguino.altervista.org/ [EMAIL PROTECTED] MyBlog http://blog.libero.it/giangiammy/ __ Yahoo!
