sys-power/nut-2.7.4-r6 failed to compile with sys-devel/gcc-11.1.0 because new version of gcc is used gnu++17 as default standard. Overriding default with -std=gnu++14 flag allow avoid this problem and nut compiles fine. Reproducible: Always Steps to Reproduce: 1. emerge nut

Created attachment 721645 [details] /etc/portage/env/sys-power/nut-2.7.4-r6 this file makes it compile (applied the patch and sent it to /etc/portage/env)
The same problem is in sys-power/nut-2.7.4-r7 Your patch works.
What I did is stick [ "${CATEGORY}/${PN}-${PV}" == "sys-power/nut-2.7.4" ] && CXXFLAGS="${CXXFLAGS} -std=gnu++14" in my /etc/portage/bashrc It has the advantage of not requiring compiler-specific modifications to the ebuild. But obviously it is an upstream problem.

But obviously it is an upstream problem. You should look into package.env. It's a cleaner way to do this.
Thanks for the hint. I created /etc/portage/env/nut.conf, and referred to it in /etc/portage/package.env and it worked! spidey ~ # cat /etc/portage/package.env =sys-power/nut-2.7.4-r7 nut.conf spidey ~ # cat /etc/portage/env/nut.conf # https://bugs.gentoo.org/show_bug.cgi?id=786702 CXXFLAGS="${CXXFLAGS} -std=gnu++14"
According to project source code available on https://github.com/networkupstools/nut there is no plans to migrating on newest C++ standard. So is better way to fix this issue is update ebuild.
