Bug 247844 – media-plugins/live: breaks with forced --as-needed

• Product: Gentoo Linux
• Status: CONFIRMED ---

[Description Diego Elio Pettenò (RETIRED) 2008-11-20 23:59:08 UTC]

I'm reporting this bug because the package in summary breaks when forcing --as-needed on through spec files (check out http://blog.flameeyes.eu/2008/11/14/problems-and-mitigation-strategies-for-as-needed for details).

Check the attached build log.

Thanks,
Diego

not much to be done here imho: live produces only static libs normally, so people are expected to link to all libs; the shared libs is a gentoo invention

I know, I think I wrote most of it, I'll see to get it fixed too, but I had to open the bug or otherwise I would have forgotten about it.

The current stable media-plugins/live-2017.01.26 works, even with the modified GCC profile described in the blog post. Resolved? Or somebody want to double-check?

still an issue i think:

Crap, I didn't realize that the build log was for a package that *depends on* media-plugins/live. Thanks for checking.

It looks like BasicUsageEnvironment needs to be linked against the regular UsageEnvironment. A few small changes make that work.

In config.gentoo-so-r1:

  -LINK_OPTS =            -L.
  +LINK_OPTS =            -L. -L../UsageEnvironment


And in BasicUsageEnvironment/Makefile.tail:

  +LIBS = -lUsageEnvironment
  +
   libBasicUsageEnvironment.$(LIB_SUFFIX): $(OBJS)
          $(LIBRARY_LINK)$@ $(LIBRARY_LINK_OPTS) \
  -               $(OBJS)
  +               $(OBJS) $(LIBS)

Maybe something else breaks after that, but "ldd libBasicUsageEnvironment.so" shows that it's linked against "libUsageEnvironment.so" at least.

yes something like that would work

it's been years but if I remember correctly it was not that easy since libs had circular deps

Still an issue with media-plugins/live-2021.08.24...
