undefined reference error when building

[003random]

Hi!

Im trying to follow the steps in https://github.com/facebookincubator/dns/blob/main/dnsrocks/docs/getting_started.md but im getting an error when trying to build dnsrocks-data for the first step.

Im running CGO_CFLAGS_ALLOW="(?s).*" CGO_LDFLAGS_ALLOW="(?s).*" CGO_CXXFLAGS_ALLOW="(?s).*" go build cmd/dnsrocks-data/dnsrocks-data.go.
Expected was a successfully builded dnsrocks-data bin. But im getting the following output/errors:
