I have Amarok 2.7.1 (Built Jun 12 2013, according to Help->About) on a new installation of Mageia 3.

If I tried to play an http source, (which works on another machine with 2.3.1), I was getting a complaint window looking for an http source plugin. Now, for some reason, it does nothing at all.

Has anyone any idea what might be the problem? Failing that, what would be appropriate debugging steps and/or useful information?

Which Phonon backend are you using? It should be either GStreamer or VLC.

Also, Mageia should have Amarok 2.8, it was released in August...

1. The back end is Gstreamer. (The sample file supplied with Amarok plays without a problem.)

2. As this problem occurred after an old release that worked, is there any reason to suppose that a newer one will be correct?
At the moment, Mageia appears to consider 2.7.1 up to date.

Which is completely outdated, and several hundred commits behind current Amarok 2.8.

FWIW: I can't reproduce this with 2.8 or later, you really should upgrade.

there is a Mageia bug report on the lack of Amarok 2.8, it's from Sept but probably still relevant - there's the suggestion to compile the src.rpm https://bugs.mageia.org/show_bug.cgi?id=11056#c3

I started trying to upgrade to Amarok 2.8.1.
Now I'm in an (apparently) infinite regression of dependencies.
That turned out to need cmake, (which I think I've installed as a binary successfully.
Selecting g++ in the Mageia Control Centre disposed of the CXX_COMPILER-NOTFOUND message
Now I have Could NOT find Taglib (missing: TAGLIB_INCLUDES TAGLIB_LIBRARIES)

What goes where to fix that?

/usr/lib/libtag.so.1.12.0 appears to be an executable file.

to compile you should read and follow this blog enty http://blogs.fsfe.org/myriam/2009/09/26 ... l-summary/

re: not finding Taglib, for compiling you need the taglig-devel package(s) which provides the needed files for use in the compilation process
