You may need to use https://github.com/gopacket/gopacket instead as it looks to be a more up to date version of the gopacket library. In terms of adding the pcap c code, you could use the --deps argument. Something like --deps=https://gmplib.org/download/gmp/gmp-6.1.0.tar.bz2, but with the pcap code instead.

another possibility is using hooks (-hooksdir), see also https://github.com/techknowlogick/xgo#hooks then you can install arbitrary pkg in you container (apt install -y libpcap-dev)

Can you give me an example? Thank you

create a directory, e.g. .xgohooks in your project's directory. place a file with the name setup.sh with following content in it:

apt update && apt install -y libpcap-dev

the call xgo with the following option: xgo -hooksdir .xgohooks ...
