My OS: Linux version 5.10.83-g1 (root@localhost) (gcc (Gentoo Hardened 11.2.0 p1) 11.2.0, GNU ld (Gentoo 2.37_p1 p0) 2.37) #1 SMP PREEMPT Wed Dec 1 23:08:57 CET 2021

clang.conf options: * /etc/portage/package.cflags/clang.conf -> net-libs/webkit-gtk: CXXFLAGS+=-stdlib=libstdc++ # error: use of undeclared identifier 'LC_ALL'

is incompatible with GCC-11.2.0.

net-libs/webkit-gtk: CXXFLAGS+=-stdlib=libstdc++ commenting this line fixes it for me here's my pull request

I have a very similar issue while installing gnome-light on a new AMD Ryzen notebook. Most packages built sucessfully, but now webkitgtk fails. Note, I have set clang use flag globally, but have not installed clang packages manually. Issue report is:

Google tells us, that ‘-stdlib=libstdc++’ is a clang option, but we are using gcc 11.3.

StefanSalewski commented 2 years ago

As Skyblueborb said, commenting out that option fixed it. But modifying the original file is ugly, and I have no idea why that option exists so that gcc can pick it.
