Description Diego Elio Pettenò (RETIRED) gentoo-dev

I'm reporting this bug because the package in summary fails to build 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).

Please note that this bug _might_ apply to -Wl,--as-needed in LDFLAGS as well; in both cases it should be fixed. Also, if this is due to the package in question not respecting user-defined LDFLAGS, you should get to fix that too.

Check the attached build log.

Thanks,
Diego

x86_64-pc-linux-gnu-gcc [...] -Wl,--as-needed [...] -o dvda [...]
make[3]: Leaving directory '/var/tmp/portage/media-sound/dvda-author-10.06/work/dvda-author-10.06/src'

Works well for me, checking if someone else can reproduce this...

forced asneeded is not the same thing as -Wl,--as-needed in LDFLAGS. forced asneeded means -Wl,--as-needed is added directly to the gcc specs. see Diego's blog about this.
