Compile Error

[stormanger]

Hi,

I have this problem when I run the build, Can you help me take a look? My build ENV: Debian11, arm64 CPU; I am using the source code of this repository: $ git clone -b current --single-branch https://github.com/vyos/vyos-build

Follow is the error:

gcc -g -Wall -I../include/ -c -o common_user_bpf_xdp.o common_user_bpf_xdp.c
