default vm memory settings for fedora eclipse
by Benjamin Konrath 05 Oct '07

05 Oct '07

Hi, Now that Eclipse requires IcedTea by deault on x86 and x86_64 I'd like to change the default vm memory settings to be something a little more sane. Right now the -vmargs option is set to "-Xms40m -Xmx256m". What should I change it to? Thanks, Ben

java.home/java.library.path etc, what can I rely on ?
by Caolán McNamara 24 Sep '07

24 Sep '07

So, for.. class findhome { public static void main(String args[]) { System.out.println(System.getProperty("java.home")); System.out.println(System.getProperty("gnu.classpath.home.url")); System.out.println(System.getProperty("java.library.path")); } } javac findhome.java java findhome I have (on x86_64) ... /usr/lib/jvm/java-1.5.0-gcj-1.5.0.0/jre file:///usr/lib64 /usr/lib64/gcj-4.1.2 For something like OOo we have two sort of requirements, at run time we'd like to dlopen libjvm.so, currently the approach I took for gcj was to stick lib/ARCH/client/libjvm.so onto the value of java.home. I guess from the output here searching through java.library.path is also plausible ? The other requirement is at buildtime to link against libjawt.so and to find the java headers. but for e.g. suse right now apparently the output of the above (for i386) is.. /usr file:///usr/lib/gcc/i586-suse-linux/4.2.1 /usr/lib/gcj-4.2.1 So what I'm wondering is if there is a canonical reference to what the various properties should refer to. i.e. are my assumptions just busted, or is e.g. the suse gcj misconfigured and if there is more correct way to find libjvm.so. And while I'm at it is there a good solid cross platform and cross java-impl test to find the correct include and link path to build against the java headers and link to libjawt and friends. C.

Packaging jgoodies-looks and jgoodies-forms
by Mary Ellen Foster 05 Sep '07

05 Sep '07

I'm thinking of packaging jgoodies-looks and jgoodies-forms for Fedora -- they're required for the GUI admin tool for the Ice distributed object middleware that I'm also wanting to package: it's a big package that's currently under review (https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=234612). I already have local packages of jgoodies that I use for building my own version of Ice, but it's not in Fedora yet so I've disable that part of the build for now in the package under review. Is there anything I should be aware of when packaging jgoodies, or should I just go for it. :) Thanks, MEF -- Mary Ellen Foster http://homepages.inf.ed.ac.uk/mef/

don't build debuginfo package
by alcapcom 04 Sep '07

04 Sep '07

Hi list, I have a problem to build a Eclipse plugin package[1] in rawhide, that seems to be a bug in the last RPM package, I will fill a bug about this today. At first view, all Java package that include classes outside a jar file can have the same troubles (I should test this today too). With the coming of AcedTea as default JRE for F8 the debuginfo package can be useful only for 0,1% of our users base, that amount of people is probably less than that because the user must work on a ppc arch using eclipse-rse (the package that give problem) and must will to debug it. So, what do you think about adding %define debug_package %{nil} on the top of the specfile while this bug is not solved in the RPM package.

FOP for F8?
by Karsten Wade 28 Aug '07

28 Aug '07

I've been watching the progress with IcedTea, and am wondering if anyone has plans to package FOP for Fedora 8? I guess I should ask the same thing about Saxon. :) We have a patch for xmlto in bugzilla waiting for FOP to be in the distro so we can set it as a target. I wanted to get a status to find out if we should/could be pushing people to get all the pieces we need for a FOP toolchain to produce PDFs from DocBook XML. cheers - Karsten -- Karsten Wade ^ Fedora Documentation Project Sr. Developer Relations Mgr. | fedoraproject.org/wiki/DocsProject quaid.fedorapeople.org | gpg key: AD0E0C41 ////////////////////////////////// \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\

Hi, > As Tom mentioned, I have successfully built the latest Batik Beta on > IcedTea. I am currently updating the Batik srpm to that version. There's a bug or two in IcedTea that causes a number of the Batik tests to crash, which I'm currently tracking down. > As for FOP, I haven't tried building that on IcedTea yet, as I am trying > to resolve a bunch of dependencies issues - I need to install many > packages first. I just did a build of FOP 0.92 (I had the sources lying around from many months ago when this last came up); it builds with IcedTea and all the bundled examples are generated properly. I haven't tried anything more complicated, ie combining FOP and Batik to run the entire toolchain, though. I also haven't tried using the srpm, so I don't know what packaging-related tasks are outstanding, and haven't tried building the newer 0.93 or 0.94. Cheers, Francis

Of course I could be wrong. :) Yep, you're wrong :) You have to to approve my requests for commit access here: https://admin.fedoraproject.org/pkgdb/ If you can't do this, let me know and I'll request to have the ownership of eclipse-pydev moved to me.

FeatureEclipse33 Status
by Andrew Overholt 23 Aug '07

23 Aug '07

Hi, Here's the status of the Fedora 8 feature of updating the Eclipse stack to the 3.3 (Europa) base [1]. I've CC'd all of the maintainers. Please reply with answers where you can. SDK (Ben Konrath) - largely done - working through a build-id issue - needs jetty5 review and inclusion (bug #202334) - need to investigate tweaking memory limits in eclipse.ini if IcedTea gets into F8 Mylyn (Andrew Overholt) - awaiting CVS rename - otherwise good to go EMF (Andrew Overholt) - would require a *tonne* of changes: probably multiple new SRPMs, lots of Provides and Obsoletes - since nothing depends upon it, I propose we drop it from Fedora 8 - anyone object? care to take it over? GEF (Andrew Overholt) - since nothing depends upon it, I propose we drop it from Fedora 8 - see last comment under EMF :) ChangeLog (Jeff Johnston) - mostly complete (I think) - Jeff? CDT & autotools (Jeff Johnston) - ready AFAIK - Jeff? Subclipse (Robert Marcano) - ready, right, Robert? PyDev (Igor Foox) - Igor: can you update to latest version that works with 3.3? If not, can you orphan it? Ben says he can take it over if you don't have time. - would be nice to get Mylyn integration in when we update sdl-nls, nlspackager (Andrew Overholt) - I'm going to remove these since there are no translations for 3.3 upstream checkstyle (Rob Myers) - things are good to go, right, Rob? quickrex (Alphonse Van Assche) - things work with 3.3, right, Alphonse? phpeclipse (Brandon Holbrook) - do things work with 3.3, Brandon? specfile editor (Alphonse Van Assche ... yes, I'm perhaps jumping the gun a bit here ;) - are we good to get this in by test2, Alphonse? Thanks, Andrew [1] http://fedoraproject.org/wiki/FeatureEclipse33

Why don't we say that we're co-maintaining pydev so that you can still help out when you have time. Thanks, Ben

Fedora 7 and Eclipse 3.3
by root 21 Aug '07

21 Aug '07

Hi, When I try to run eclipse 3.3 on fedora 7, it gives some memory leak warnings as following GC Warning: Repeated allocation of very large block (appr. Size 651264) May lead to memory leak and poor performance I get this warning even after changing memory size to max (512) in eclipse.ini And later, when I add more plug-ins to eclipse and try running that, it gives segmentation fault. Please let me know if there is any workaround. Thanks, Deeptika
