Linking to libjava.so
by Orion Poplawski 21 Sep '07

21 Sep '07

I'm trying to package up a java package for octave that links to libjava.so. Problem I'm having is that when octave tries to load the module at run time it can't find libjava.so. How should this be remedied? Thanks! -- Orion Poplawski Technical Manager 303-415-9701 x222 NWRA/CoRA Division FAX: 303-415-9702 3380 Mitchell Lane orion(a)cora.nwra.com Boulder, CO 80301 http://www.cora.nwra.com

Eclipse and JVM memory settings
by Andrew Overholt 18 Sep '07

18 Sep '07

Hi, Now that we have people using Eclipse on IcedTea, we have people starting to hit memory limits. I don't understand the situation very well, but here are some links to Eclipse bug reports, etc.: http://www.eclipsezone.com/eclipse/forums/t101303.rhtml http://wiki.eclipse.org/FAQ_How_do_I_increase_the_permgen_size_available_to… https://bugs.eclipse.org/bugs/show_bug.cgi?id=195897 - the Eclipse launcher (largely written in C) can tell if it's running on a Sun VM on Windows -- it looks like it reads .dll headers -- but not on Linux I spoke briefly with Andrew Niefer and a few other people on IRC and here are a few options for fixing the launcher to work with the -XX options in both the Sun VM and non-Sun VM cases: 1. try starting the VM using the invocation api (using libjvm.so) with the PermSize argument and see if it fails - if it does, launch without the option. This may add some startup delay to VMs that don't support this option. This was suggested in the eclipse.org bug I link to above. 2. look for a jre/LICENSE text file and seeing if it starts with "Sun Microsystems". Andrew Niefer suggested this option. Can anyone think of anything better? Note that I don't want to add a shell wrapper around the binary Eclipse launcher unless we absolutely have to. The Eclipse launcher code can be seen in CVS here: :pserver:anonymous@dev.eclipse.org:/cvsroot/eclipse Module: org.eclipse.equinox.executable Branch: R3_3_maintenance (or HEAD if you like) Specifically, library/win32/eclipseWin.c in the isSunVM() function. library/eclipseNix.c has an isSunVM() that just returns 0.

bluemarine crashes
by Matej Cepl 11 Sep '07

Trying Blue Marine (http://bluemarine.tidalwave.it) which certainly didn't work with GIJ, so I hoped it actually could work with java-1.7.0-icedtea-1.7.0.0-0.14.b18.snapshot.fc8 from Rawhide. Unfortunately, although installation went smoothly, this is the output of attempt to run the program itself after it was installed in $HOME/.blueMarine directory (long lines broken in indicated places to make slrn happy): [matej@viklef .blueMarine]$ java -version java version "1.7.0" IcedTea Runtime Environment (build \ 1.7.0-kojibuilder_28_aug_2007_13_29-b00) IcedTea Client VM (build 1.7.0-kojibuilder_28_aug_2007_13_29-b00, \ mixed mode) [matej@viklef .blueMarine]$ cat blueMarine.sh #!/bin/sh # $Id: blueMarine.sh 2378 2007-07-23 10:16:45Z fabriziogiudici $ export BLUEMARINE_HOME=/home/matej/.blueMarine export MEMORY=-Xmx512M export VERSION=0.9.RC1.2533 export AWT_TOOLKIT=MToolkit export CLASSPATH=$BLUEMARINE_HOME/bluemarine/platform7/lib/boot.jar\ :$BLUEMARINE_HOME/bluemarine/platform7/lib/boot2.jar\ :$BLUEMARINE_HOME/bluemarine/platform7/lib/org-openide-modules.jar\ :$BLUEMARINE_HOME/bluemarine/platform7/lib/org-openide-util.jar\ :$BLUEMARINE_HOME/bluemarine/platform7/modules/ext/updater.jar /usr/lib/jvm/java-1.7.0-icedtea-1.7.0.0/jre/bin/java -ea $MEMORY\ -Dnetbeans.osenv.nullsep=false\ -Dnetbeans.home=$BLUEMARINE_HOME/bluemarine/platform7\ -Dnetbeans.logger.console=false -Dit.tidalwave.openide.app=$0\ -Dit.tidalwave.bluemarine.showtabs=false\ -Dit.tidalwave.bluemarine.version=$VERSION -cp $CLASSPATH\ it.tidalwave.netbeans.boot.Main [matej@viklef .blueMarine]$ ./blueMarine.sh Exception in thread "main" java.lang.UnsatisfiedLinkError: \ Can't load library:\ /usr/lib/jvm/java-1.7.0-icedtea-1.7.0.0/jre/lib/i386/motif21/libmawt.so at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1668) at java.lang.Runtime.load0(Runtime.java:788) at java.lang.System.load(System.java:1042) at java.lang.ClassLoader$NativeLibrary.load(Native Method) at java.lang.ClassLoader.loadLibrary0(ClassLoader.java:1769) at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1686) at java.lang.Runtime.loadLibrary0(Runtime.java:841) at java.lang.System.loadLibrary(System.java:1067) at sun.security.action.LoadLibraryAction.run(LoadLibraryAction.java:68) at sun.security.action.LoadLibraryAction.run(LoadLibraryAction.java:48) at java.security.AccessController.doPrivileged(Native Method) at java.awt.Toolkit.loadLibraries(Toolkit.java:1626) at java.awt.Toolkit.<clinit>(Toolkit.java:1648) at it.tidalwave.netbeans.boot.Main.main(Unknown Source) [matej@viklef .blueMarine]$ Is it expected (considering the state of the IcedTea development), or should I file a bug (where?). Thanks for any reply, Matěj

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. [1] https://www.redhat.com/archives/fedora-devel-java-list/2007-August/msg00009… Thanks, Alphonse
