java library not found

Hello, what version of the iriverter package were you using when this error occurred? iriverter was recently updated to 0.16-0ubuntu2

Also any more details about your installation that might help, such as the version of java-gcj-compat and libswt3.2-gtk-java that you have installed.

hello,

I tested this on stock feisty beta and iriverter launches and works properly. Can you test again? Some dependent packages were probably updated.

Yes, it runs under liveCD, but it doesn't run on my main install. I have everything updated, so it should run fine.

Sorry to say that I'm having the same problem too. I actually had problems with iriverter in Edgy, so I really wasn't expecting it to work here -- but now that it is being offered in the repositories, I guess I should help take the kinks out.

First, the information that you requested, but for my system:

dpkg -l iriverter java-gcj-compat libswt3.2-gtk-java
Desired=Unknown/Install/Remove/Purge/Hold
| Status=Not/Installed/Config-files/Unpacked/Failed-config/Half-installed

If you need more info, feel free to ask.

To expand on the issue, I also tried a fix on the Ubuntu forum, where this line:

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/lib/jni

...is added into the Terminal before opening iriverter also from the Terminal.

Indeed it seems to work at first since the program's interface looks normal. However, when trying a to convert a video file, the program crashes and this is added into the error log:

Any help on the matter is appreciated, but please take your time at least on my account. I still have Windows and 32-bit Linuces to run iriverter in during the interim.

I have this issue too, but I am using SUN's java package (from the repository though, not from java.com).

I managed to solve it thanks to this post:
http://ubuntuforums.org/showpost.php?p=1063854&postcount=13

Basically:
export LD_LIBRARY_PATH=/usr/lib/jni/
iriverter

Isak: that also solves the problem for me. However for the package I think a global solution would be preferred.

Looking inside /usr/bin/iriverter it seems that if we've just appended ":/usr/lib/jni" after the -Djava.library.path= part it would work just fine:

java -Djava.library.path=$LD_LIBRARY_PATH:${exec_prefix}/lib:/usr/lib/jni -classpath $CLASSPATH:${prefix}/share/java/iriverter.jar:/usr/lib/java/swt.jar org.thestaticvoid.iriverter.ConverterUI $*

Slightly less hack-ish, hopefully? :)

I'm having the same problem on latest Gutsy too. the "export LD_LIBRARY_PATH=/usr/lib/jni/" trick works though.

[Expired for iriverter (Ubuntu) because there has been no activity for 60 days.]

bug is still not fixed in Gutsy.

The fix is given above and the bug should not be hard to fix.
iriverter is unusable as it without this fixes.

by the way there is an HORRIBLE sound bug, with mostly white noise when I encode for H300.
I have noticed this problem since feisty and I don't know how to fix that !!!!

I can confirm that this bug is still present in the latest package in Gutsy. I made the (very easy) fix Jerry Chong recommends above, and iriverter loads without any errors.

Since this is a simple change to one file, it's a bit disappointing that it hasn't been fixed yet...

I can confirm this bug, and also that the fix by Jerry Chong works.

about the white noise with mencoder mp3 encoding, I still have this problem but it seems it's because ffmpeg is not built with mp3 support.
However even when I use a fine compiled ffmpeg it doesn't fix it, I can't find what is the problem

The bug is still present in gutsy.

"export LD_LIBRARY_PATH=/usr/lib/jni/" fixed the problem.

This bug is also present in the Hardy beta. Performing "export LD_LIBRARY_PATH=/usr/lib/jni/" corrects the problem.

This problem still exist in an updated 8.04 Kubuntu system.

The fix from Jerry worked for me as well, thanks Jerry.

Thanks jerry it fixes the issue on Ubuntu 8.04 amd64

Thanks Jerry it fixes the issue on 8.04 x86

Applies on both Gnome and KDE (and likely more), so this is not a problem with KDE. It was caused by the latest version of iriverter, so I think it's safe to say it's just an iriverter problem.

I've been able to duplicate and then solve this here, under Ubuntu 8.04 (on x86).

The issue causing mild confusion about this bug is that the current package works fine using the default (java-gcj) JRE. However, if one installs the Sun JRE and sets it as the default using

  sudo update-java-alternatives -s java-6-sun

*then* the symptoms of this bug appear.

Adding the extra library directory /usr/bin/jni is harmless to the java-gcj JRE.

The solution now seems clear: add that directory to the library path in the launch script. Therefore, I have created a "fixed" package of iriverter, the .debdiff of which is attached.

I'll do my best to see this through to a new revision upload in the next few days. There are a few packaging and lintian warnings I'll probably clean up while I am "inside" the iriverter package tree, too.

Feedback is very welcome -- I'm new to Ubuntu development, though not to Linux or to software development.

Jonathan

Updated debdiff attached below which also cleans up a few lintian issues.

See http://revu.ubuntuwire.com/details.py?package=iriverter for the REVU upload.

Following some feedback on #ubuntu-motu, here is a revised debdiff.

Jonathan

A (hopefully final) new debdiff with improved debian/changelog per advice from cody-somerville on #ubuntu-motu
