[gentoo-user] decplean left libtunepimp.la behind

Had a depclean session which removed:

 media-libs/musicbrainz
    selected: 2.1.5 
   protected: none 
     omitted: 3.0.2 

Then I followed up with revdep-rebuild and this comes up:

 * Generated new 1_files.rr
 * Collecting complete LD_LIBRARY_PATH
 * Generated new 2_ldpath.rr
 * Checking dynamic linking consistency
[ 67% ]  *   broken /usr/lib/libtunepimp.la (requires -lmusicbrainz)
[snip ...]

 * Assigning files to packages
 *  !!! /usr/lib/libtunepimp.la not owned by any package is broken !!!
 *   /usr/lib/libtunepimp.la -> (none)


What is "-lmusicbrainz" and is it telling me to just delete 
/usr/lib/libtunepimp.la?

It's a library for accessing music metadata from http://musicbrainz.org/

I think the *.la file might be left over because it was changed after
being emerged (say, you upgraded to a new gcc and the .la files were
updated by tool rather than re-emerging everything in the world). So
unmerge would leave it behind because the checksum doesn't match that
which was originally installed.

So, yes, I would delete it. :)

Look into any *.la file and you will see stuff like this:

/usr/lib/libsqlite3.la:dependency_libs=' -ldl -lpthread'

The .la files are hints to the linker telling it how to do stuff, the -l bits 
reference libraries that will be needed. Far more often than is acceptable, 
libtool cocks this up in spectacular ways, which is why we had

lafilefixer --justfixit

for so long, and why it is now built into portage.

I have musicbrainz, but I do not have /usr/lib/libtunepimp.la and yours is 
orphaned anyway - it probably got left behind long ago when depclean didn't 
know it was related to musicbrainz.

Just delete the thing, be done with it, revdep-rebuild will stfu and you will 
be a much happier chappy

Thanks guys, it's been blitzed!

I think the long-term plan is to eliminate the *.la files entirely,
once all packages have been updated as such by their maintainers, so
hopefully this kind of problem will vanish in the not-too-distant
future. :)

It's closer than you might think, there are very few packages left to be 
fixed:
