(The correct URL is [1].) The undefined symbols should be defined by cgo as it's in the "C" "namespace" used by cgo (see line 93 in that file and the information on how cgo works in general). Hence I would expect this symbol to be defined through some header file of the libpcap library. So I'd start digging from there. Note that you can tell `go build` to leave its intermediate files behind by running `go build -work` and then inspecting what was generated by cgo there. That is, grep the generated stuff for PCAP_NETMASK_UNKNOWN. Well, in theory, it's possible that some weird cgo-related bug crept into the cgo subsystem but I'd start from the other end. 1. https://github.com/google/gopacket/blob/master/pcap/pcap.go#L594 -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
