I tried to compile batman-adv-2023.1 for a standard debian bullseye
kernel 5.10.0-25 but it fails with:
batman-adv/gateway_common.c:55:8: error: implicit declaration of
function ‘kstrtou64’ [-Werror=implicit-function-declaration]
55 | ret = kstrtou64(buff, 10, <hroughput);
cc1: some warnings being treated as errors
Tried make CFLAGS="-Wno-error=implicit-function-declaration" but that
doesn't help. Successfully compiled on 5.15.0 (ubuntu LTS).
Any ideas on this?
