IRIX6.5 + PTHREAD?!
Can anyone answer my question! I try to port the current CVS version on IRIX 6.5 using pthread. Here are the errors I've got while I run a multithreaded java program. 1) It looks like the thread does not get suspended? ==> The assertion in ./systems/unix-pthread/thread-impl.h fails: assert(nt->suspendState == SS_SUSPENDED); However, if I comment it out, the following error occurs! 2) ==> locks.c:147: failed assertion `*lkp == LOCKINPROGRESS' Whether I need to modify the threading subsystem and the locking subsystem! Please advise! Thanks, Dan

Re: Num-Lock proposed fix
'VK_NUMx' keyConst, and 'x' keyChar makes sense (otherwise, the VK_NUMs would be pretty useless). I'll check how I can add it to the event handling (there was a bug for KEY_TYPED function keys, anyway). -- Peter -- Peter C.

Re: General question (about Kaffe CE)
Hello everyone,
Yes, there r two version of Kaffe.
Desktop and Custom Edition.
Desktop as name says can straight away work with your Windows or X server
environment.
Custom, which I have been working with for w while, is the one which gives
the complete flexibilty of running Kaffe ontop of bare DOS, or Linux
without any X Windowing system and thus giving chances to use Kaffe to use
in embedded systems. For custom Edition one has to sign an agreement with
transvirtual..
Hope it answered most q's..
Rgds,
Ganesh

Sorry, I thought the question was "are kaffe and the JDK completely different products". Yes the GPL and custom editions have much in common. -Archie ___ Archie Cobbs * Whistle Communications, Inc. * http://www.whistle.com

Yes, everyone is invited to hack on kaffe except those poor folks that agreed to a Sun license and looked at Sun source code. It is important to note that this only applies to source code for the JVM and class libs. You will need to look at the Sun JDK docs and the language specs if you want to help out. > You should probably add that what Julien *shouldn't* do is look at the > Sun JDK sources to see how to fix kaffe.

Re: name mangling bug in kaffeh
Doug, now that you have identified the problem, you sould also taking a crack at fixing it. I think the first patch I ever wrote for Kaffe was for the kaffeh program. kaffeh is small and simple, it is a great place to get started hacking on Kaffe. Just check out the CVS version, make your changes, run "cvs diff" and post your patch to the list. Mo Dejong Red Hat Inc.

Num-Lock proposed fix
Looking around the Sun Java bug data base and other source, it seems that the Num Lock (and other Lock) problem is still unresolved, and a solution is planned for the Input Method framework. About kaffe, i think the following should be consistent with the Java spec: If the NumLock is pressed, the KeyEvents generated will be: 1) KeyPressed, with keycode VK_NUMPADx (x : 0..9) 2) KeyTyped, with keychar 'x' 3) KeyReleased, with keycode VK_NUMPADx Would this break the compatibility with existing Java code ? If yes, what other solution can be considered ? We are considering this fix for inclusion in the Mandrake/MacMillian distributed kaffe rpm ... so the question is rather important ...

name mangling bug in kaffeh
hi, i tried to post this bug on the web site last night, but it didn't seem to work. When using kaffeh to emit jni headers, underscores in method names are not correctly handled. e.g. get_packet should end up as get_1packet in the .h file. Kaffe is correctly looking for the get_1packet in the shared library, however. Also, overloading is not handled -- but I already saw this in the bug list. cheers, doug -- Douglas S. J.

You should probably add that what Julien *shouldn't* do is look at the Sun JDK sources to see how to fix kaffe. In fact if he wants to contribute to kaffe then he shouldn't look at Sun's sources at all, right? -- Eur. Ing. Chris Gray MBCS C. Eng. [EMAIL PROTECTED]

With KaffeCE, AFAIK, there is some makefiles for dos, win32 and AWT for dos and some others that are not in the GPL one, but not a different JVM as the GPLed Kaffe Tim? Peter? Something to say? -jec
