libwx_gtk2u_media-2.8.so.0 missing from libwxgtk2.8-0

This also keeps the wxruby gem from running.

Yeah, that's the reason why I'm affected by this, too. I solved this by compiling wxWidgets myself to /opt/wxwidgets-2.8.11. However, this is only a temporary solution as I don't like installing software that is already provided by the package system.

Debian removed --enable-mediactl in 2.8.10.1-1, to close Debian bug #493090 (libwxgtk2.8-0: unwanted dependency on libgconf) and remove wx's dependency on gconf. Fair enough, but they really should have provided a wxmedia package instead of just removing it. :-(

I'm writining GUI apps on Ruby with wxRuby as GUI lib. Now all that work great on Lucid doesn't even start with this error:

<internal:lib/rubygems/custom_require>:29:in `require': libwx_gtk2u_media-2.8.so.0: cannot open shared object file: No such file or directory - /var/lib/gems/1.9.1/gems/wxruby-ruby19-2.0.1-x86-linux/lib/wxruby2.so (LoadError)

 from <internal:lib/rubygems/custom_require>:33:in `rescue in require'
 from <internal:lib/rubygems/custom_require>:29:in `require'
 from simplegui.rbw:3:in `<main>'

So, all who use this lib are affected.

This bug affects me as well. Ubuntu 10.10 (Well, xfce)

Man this really gets on my nerves... And I'm only just trying to getting wxruby up and running so I can start learning it.

Also affects Ubuntu 11.04 Natty Narwhal:

naturel@naturel-desktop:~$ ruby1.9.1 -e "require 'wx'"
<internal:lib/rubygems/custom_require>:29:in `require': libwx_gtk2u_media-2.8.so.0: cannot open shared object file: No such file or directory - /var/lib/gems/1.9.1/gems/wxruby-ruby19-2.0.1-x86-linux/lib/wxruby2.so (LoadError)

This bug was fixed in the package wxwidgets2.8 - 2.8.11.0-0ubuntu9

---------------
wxwidgets2.8 (2.8.11.0-0ubuntu9) oneiric; urgency=low

  * debian/rules: reenable mediactrl. This allows libwx_gtk2u_media-2.8 to be
    built, as this is required by some applications (LP: #632984)

Will it be published in natty backports?

It should actually be a stable release update for 10.10 and 10.04:

"Bugs which represent severe regressions from the previous release of Ubuntu. This includes packages which are totally unusable, like being uninstallable or crashing on startup."

Hi,

I'm not sure this will be accepted as a SRU, as there is only one functionality that is missing n the package and all the remaining package works fine.

Anyway, as I was requiring it for a package I maintain, I backported it in a PPA. You can find the fixed packages there: https://launchpad.net/~dvdstyler-maintainers/+archive/ppa/+packages

Glad that this is fixed, but wxRuby now complains like this (I'm running Natty with Fabrice's PPA updates applied):

Shall I file another bug for this one?

@Marvin Gülker: it seems that your problem has already been detected and a workaround has been found. Please see https://bugs.launchpad.net/ubuntu/+source/libwx-perl/+bug/754513

Sadly, I'm not a Perl programmer, so the comments about CPAN don't help me much. It seems, that installing wxPerl via CPAN means compiling it, and compiling wxRuby is quite an adventure (I've done it some times [takes nearly eternity...], but at the moment it just refuses to build--however, this is something the wxRuby devs have to solve).

Incredible, I just wanted to verify bug #756237 for Ubuntu Natty, but each time I think I'm a step nearer to it, something else prevents me from doing it. Lol, I can't get an application to start that I want to crash later on. :p

This bug is marked as 'fix released'. What do I have to do to correct it? Uninstall the package and reinstall? Or is there an easier way?

John: it's released in oneiric. If you want this fix for natty or maverick, look at the PPA Fabrice mentioned.

Hello,
I read (and maybe understand) than this bug is fixed. Thank you for fix it... can i profit this fix, and how to do ? (please)
OK... so, for me (ubuntu-12.04), when i use wxpython-2.6.x with python-2.7, this not works at all.
So... i not said the bug is not fixed, i said that i don't know (and nothing is explain here) how to be able to see it runing (and use the wx.media and mediaCtrl implemented).
If there is a generous and sympathic user who know and want to tell me what i can do for make it runing, i will be very happy.
I just would like to use wxpython and its wx.media runing fine (if it is possible).

thank you for share more information for beginners on ubuntu/linux style plateform.

Hello again,
Thanks for your answers (difficult for me to read all the answers... it is too much), i have a news with this:
in the code, i add 'import wxversion', and 'wxversion.select("2.8")'.
Because i think there is more than only one wxwidget installed by the packages manager (hum, hum) and maybe used the older (which one that seems to not be fixed inside the pakages list of ubuntu-12.04).
So... thanks for all and have a good day(s).
