Anyone using gnu gcj and SWT on PPC Linux

[Kevin.Hendricks]

Hi,

I just found a wonderful article on IBM developerworks about using
the gnu gcj (java compiler)that comes with gcc  with SWT-gtk or 
SWT-motif
to build java gui style apps that can be compiled to complete native 
code.


I was wondering if anyone has used SWT or Eclipse (the Java IDE) under 
PPC
Linux and if so have they tried integrating SWT and gcj with any 
success?


Hints or trick to get this to work welcomed.

Thanks,

Kevin

Announce: OpenOffice.org 1.1RC for YDL 3 and other PPC Linux Dists

[Kevin.Hendricks]

We are pleased to announce that the release candidate of the next
version of the OpenOffice.org Office Suite - OpenOffice.org 1.1 - is now
available for download from:

http://www.openoffice.org/dev_docs/source/1.1rc/index.html

For PPC Linux (Yellowdog 3 and other glibc-2.3.2 distributions) 
please see:


ftp://ftp.yellowdoglinux.com/pub/yellowdog/software/openoffice
 and any of its mirrors


OpenOffice.org1.1 RC is expected to be feature complete with no more
features added before the final OpenOffice.org 1.1 release.

New features since OpenOffice.org 1.1 Beta 2 release include:
* A "talkback" style crash reporter to collect stacktrace
  and error information
* New command-line parameter -start to automatically
  start a presentation after the document is loaded
* Ability to update existing OpenOffice.org 1.0.x single-user 
installations

* Support for drawing objects in headers and footers
* An example XSLT filter for Office 2003 XML format
* Support for Microsoft(TM) Excel 95(TM) (and older) form 
controls

* UNO python bridge - python is now a first class
  language for creating UNO components for OpenOffice.org
* Built-in spell checking dictionaries for English (UK) and 
Italian
* Built-in hyphenation support for Danish, English (UK), 
German, and Russian

* Integrated Bitstream Vera fonts
* Improved spelling suggestions using n-gram scoring

The highlights of OpenOffice.org 1.1 are:

* Many new import/export formats like DocBook, several
  PDA document file formats, flat XML and XHTML
* Support for Portable Document Format (PDF) export
* Support for Macromedia Flash export
* Support for user provided XSLT based filters for both import
  and export of XML based formats, providing ability to easily
  support 3rd party XML file formats
* Support for Complex Text Layout (CTL) and vertical writing
  languages such as Thai, Hindi, Arabic, Hebrew
* Enhanced integration with Java
* Support for accessibility
* Enhanced support for add-on components
* Improved on-line help
* Support for many more new languages and locales compared to
  the OpenOffice.org 1.0.x versions

For a more complete list of features please see:

http://www.openoffice.org/dev_docs/source/1.1rc/features.html

For people interested in getting started helping OpenOffice.org become
better, faster and above all more bug free, a page detailing how to best
file bugs, how to help the QA project deal with bug reports, how to
run OpenOffice.org with Valgrind and a number of ready made bug query
scripts, exists at:

http://www.kegel.com/openoffice/

Thanks for supporting the OpenOffice.org project.

Re: openoffice.org in Sid

[Kevin.Hendricks]

Hi,

Actually, I can make an OOo 1.1 RC5 ppc Linux available for Debian 
users if someone wants one.  I was hoping to wait until it becomes OOo 
1.1 final and then release it to the YDL mirrors, but if someone has 
some disk space I can sftp/ftp it to, I would be happy to post RC5 for 
Debian ppc Linux users by uploading it tonight so that it is ready by 
tomorrow.

Hi All,
I find it hard to believe that everyone who is running Sid has been
without Oo for the past two weeks (due to no openoffice.org-bin), can
someone tell me what the deal is and what you have done to get around
it??


Actually, it has been more like a month since 1.0.99+1.1 was released 
without openoffice.org-bin for anything other than i386, but nobody 
should be without Oo. Since the new version is missing a dependancy, 
dpkg/apt-get/dselect/aptitude/kpackage should not have uninstalled Oo 
1.0.3-2.


If you personally can't install it, try:

 apt-get -t 1.0.3-2 install openoffice.org openoffice.org-bin

And you can always get the slightly older 1.1 RC version from 
http://www.openoffice.org/ and manually install it.

Re: java with mozilla-firebird & mozilla

[Kevin.Hendricks]

Hi,

Not on YellowDog Linux it is not.  You really should not have problem 
interfacing gcc 3.3.2 with gcc 3.2.2 with C++ code since others have 
reproted success.

That was compiled with gcc 3.2.2 and does work with mozilla compiled
with gcc 3.2.2 as well as OOo compiled with gcc 3.2.2.


The current gcc compiler is 3.3.2, so I think that the JRE should be
compiled with this version.

OK. So, how do you explain the following crash?

On the blackdown site, similar crashes were reported as JDK bugs:

Or is it a libc bug? I have libc6 2.3.2-9.

Re: CFP (Call for Participation) Debian PPC64

[Kevin.Hendricks]

Hi Alan,

Is there some pdf doc that describes all of the abi details (sort like 
the old Sun/Motorola SysV abi for PPC) or even a summary that describes 
how the linux ppc32 (almost sysv abi) and the linux ppc64 abi differ.  
Also, something that describes any synchronization (sync, isync, vs 
...) differences and cache line size differences would be nice too.


The C++ to uno bridge code in OOo will require updating if there is 
ever going to be a native Linux PPC64 version of OOo (people are 
already working on x86_64, Alpha, Sparc 64, etc).


Any helpful links appreciated.

Thanks,

Kevin

What does it do about floating point constants?


Puts them in the TOC, then accesses with, eg.

lfd f1,some_offset(r2)


Recent versions of GCC have an annoying bug which makes many
(but not all) floating-point constant load take 3 instructions
in 32 bit mode (never tried 64 bit, no hardware):

li rx,[EMAIL PROTECTED]@
la ry,[EMAIL PROTECTED](rx)
lfd frz,0(ry)


Hmm, that does seem a bit poor.


Function descriptors instead of single pointer to the first
instruction I believe. I'm not sure that it's that bad either.


Yes, ppc64 function pointers are pointers to a function descriptor.

Re: 2.4.22-ben2 safe? [Fwd: [SECURITY] [DSA-403-1] userland can accessLinux kernel memory]

[Kevin.Hendricks]

Hi,

BTW: this patch is not even part of 2.4.23-pre5-ben0 that I grabbed  
just a few days ago.


So unless you are using 2.4.23 FINAL you probably should look and see  
if that patch is

present and if not add it to your tree.

Re: searching Java & flash for mozilla

[Kevin.Hendricks]

Hi Michel,

Sorry, my fault.  I was supposed to review the changes needed to get it 
to build with mozilla 0.9.7 (and try to check it out with cvs 0.9.8) but 
I have not had a moment to do that yet.


I will do my best to do that this weekend.  Once that is done, we will 
release.


Sorry about the delay but I am overwhelmed with real work lately.

Re: java - is there any?

[Kevin.Hendricks]

Hi,

Go to the IBM (developerWorks?) site and download a very nice JDK 1.4.1 
for p-series Linux (32 or 64 bit) PPC JDK.  It has a very fast JIT and 
seems to work well for me.


You can then add some symlinks to make it look exactly like a Sun JDK 
in internal layout which allows it to be used almost-out-of-the box to 
handle things like the OpenOffice.org build and etc.

One thing I am not used to is the lack of proprietary binaries.  In
x86 land a sadly high number of necessary (for some) tools are
available in binary-only form.  Are there any current (ie 1.4 or 1.5)
java releases for linux on the powerpc?  I found the 1.3 package from
blackdown, but nothing newer.  Sun seems wholly uninterested in the
Mac platform because their site doesn't even have OSX (or OS9)
downloads let alone linux.  For work I can't rely on gij or kaffe -
they aren't nearly complete enough (yet?).

Re: Is 2.6.x being updated from rsync?

[Kevin.Hendricks]

Hi,

I took at look at kernel org and those patches are are quite OLD.

Ben if you are out there, could you please confirm we should in fact be 
using Linus's trees or not?


Kevin


I read on
http://penguinppc.org/dev/kernel.shtml

"Patches between the PowerPC trees and Linus's tree can be found on
kernel.org.  Patches between Ben's kernel and the main tree can now be
found at kernel.org."

So IIUC there are still differences between Ben and Linus trees.

Could someone knowing more please explain what's going on?

TIA

Best Regards
Wolfgang
