[Comment 2 Mike Gilbert 2021-02-07 18:35:23 UTC]

I assume this is failing because your libc is built without ipv6 support.

gdb doesn't have an "ipv6" USE flag, so there might not be any way to make this work.

[Comment 3 Sergei Trofimovich (RETIRED) 2021-02-11 23:53:50 UTC]

gdb assumes both ipv4 and ipv6 available at the same time.

I suggest filing an upstream bug at https://sourceware.org/bugzilla/enter_bug.cgi?product=gdb and asking if it's an environment gdb wants to support.

[Comment 4 David Seifert 2022-01-02 10:32:10 UTC]

uclibc support in Gentoo has been removed.
