[gentoo-user] "The sound of Silence" by glibc

[tuxic]

Hi,

emerge -e @world installs glibc

On my system this kills the build of pulseaudio...which in turn make
my linux PC one of the most quiet ones...sigh:

From the compilation output of pulseaudio:

How can I get out of this...

Use "emerge -a --resume --keep-going". This should continue the world 
rebuild, and will not abort the emerge when pulseaudio (or any other 
packages) fail to build. Then at the end, emerge will print a list of 
packages that failed to build. You should then fix those if you can. How 
urgent it is to fix them depends on the packages, of course.

Looks like pulseaudio is redefining a glibc function and it is doing it in the wrong way
by adding the static keyword. To me it looks like a pulseaudio problem, not glibc. Not
much you could do except maybe try to comment out the invalid or outdated 'static'
declaration from the pulseaudio's memfd-wrappers.h, but that will probably bring out other
problems. Better open a bug upstream.

There's a pulseaudio-11.1 version in portage, have you tried that already?
