Sorry I did not investigate, but there is probably a different installation of the pcap library.

I have this in a config file:

pcaparm=$deps/libpcap/build-aarch64/install # requires big changes in DPDK
#export PKG_CONFIG_PATH=$PKG_CONFIG_PATH:$pcaparm/lib/pkgconfig

I don't remember what are the big changes required, and why it is disabled.

Checking Meson, libpcap is indeed not found on aarch64:

Run-time dependency libpcap found: NO (tried pkgconfig)
Library pcap found: NO

Can you check whether the error can be related to the absence of libpcap?
