My environment is Raspberry Pi 3 (64 bits). I need vhost_traffic_status enabled on nginx to monitor it. I am using gcc 11. Sorry, but I do not have the logs but, I believe they will not be required because this bug was reported here [https://github.com/vozlt/nginx-module-vts/issues/223]. I (believe that I have) fixed this issue by adding the following lines to /var/db/repos/gentoo/www-servers/nginx/nginx-1.20.1-r2.ebuild : if use nginx_modules_http_vhost_traffic_status; then myconf+=( --with-cc-opt=-Wno-stringop-overread ) fi Is this enough? And again, I am sorry because I have no logs.
