Which version of xdp-tools? And could you please post the output of ./configure?

[a783706]

is the latest xdp-tools，hello

[a783706]

Erm, you said you are using libbpf 1.2, but the configure script says 0.3.0; how are you using libbpf 1.2?

[a783706]

hello，
I'm indeed using libbpf v1.2, I don't know why the configure script shows version 0.3.0

I did "apt install libbpf-dev" a long time ago, does that have something to do with it?

[tohojo]

Ah. That's just the version of libbpf that bpftool is built against; the xdp-tools configure is picking up the system version (from the libbpf-dev package). It's a bit weird that compilation fails, then, though... How did you install libbpf 1.2 / bpftool?
