Binary package hint: transcode

Hi,

using the logoaway filter in transcode produces the following error:

[transcode] warning: Unable to load filter logoaway: /usr/lib/transcode/filter_logoaway.so: undefined symbol: DestroyConstitute

This is also known for other distribution (e.g. Debian) which I think is then an upstream problem. The problem with filter_logoway is that during the compilation there is no check of all used external funtions. A couple of months ago the API of imagemagick has changed and DestroyConstitute() was replaced by ConstituteComponentTerminus() .

So, the solution is to change the in line 868 of filter/filter_logoaway.c

DestroyConstitute(); <--> ConstituteComponentTerminus();

I found this in the 10.04 development version, but as I said this error may exist also in older distributions as well.

>lsb_release -rd
Description: Ubuntu lucid (development branch)
Release: 10.04

The hint in the change of the imagemagick API I found on launchpad as well:

https://code.launchpad.net/~ubuntu-branches/ubuntu/lucid/dx/lucid

Maybe it is worth to check other packages in lucid as well before the final release!

Here there is a patch that fixes the issue:
https://bugs.launchpad.net/ubuntu/+source/librmagick-ruby/+bug/518122/comments/27

[Marco Cimmino (cimmo)]

Sorry I meant that same issue affects package: librmagick-ruby and the patch to fix it is above ^.
Please fix!

[Clint Byrum (clint-fewbar)]

Marco, can you provide a snippet of Ruby that reproduces this issue so that we can have a clear test case for it?

The patch looks fine and I'll work on building a source package to upload to lucid-proposed soon, but without a repeatable test case it won't be possible to verify it.

[Marco Cimmino (cimmo)]

I cannot share the code I use, but I will try to make a simple example.

[Marco Cimmino (cimmo)]

Here we go, you need a png file called example.png, whatever image should work ok.
Launch then inside the dir with: ruby example.rb

and observe the issue, thanks.

[Marco Cimmino (cimmo)]

Even found the upstream fix
https://github.com/rmagick/rmagick/commit/98857201d56b2b987796309e8a5ea32f4d8ddc8c

Packaged my self since no sign of life here:
http://www.marcocimmino.net/2011/07/30/librmagick-ruby-for-ubuntu-lucid-32-bit-with-destroyconstitute-missing-symbol-fixed/

I didn't add the patch but applied right away.
Ubuntu please fix this broken package in your latest LTS release!!!

[Alessio Treglia (quadrispro)]

Hi,

thanks for the report.

Could you try to reproduce this with the latest upstream release available in Quantal?

[Marco Cimmino (cimmo)]

Alessio, this bug is gone after Lucid, the point of the ticket is you left a LTS release with a package that is useless because doesn't use the correct APIs.

You used a bunch of packages that were incompatible between them!
Changing tickets to incomplete after so many months is just embarassing, after we provided even the patch.

Plus Quantal is totally off topic here.

[Alessio Treglia (quadrispro)]

Sorry, it's my fault, it was a kind of automatic message.

The suggested patch looks good to me, so I'm closing the bug assigned to transcode and subscribing the sponsors team to fix the issue in librmagick-ruby.

Thanks for the great work!

[Stefano Rivera (stefanor)]

Unsubuscribing ubuntu-sponsors. Please re-subscribe them whin this is ready for review.

lucid has seen the end of its life and is no longer receiving any updates. Marking the lucid task for this ticket as "Won't Fix".
