[pkg-go] Bug#816519: golang-github-google-gopacket-dev: missing Depends/Recommends of external libs

[Ximin Luo]

Package: golang-github-google-gopacket-dev
Version: 1.1.11-2
Severity: normal

Dear Maintainer,

Some of the functionality of this package depends on third-party libraries.
See https://godoc.org/github.com/google/gopacket e.g.:

* pcap: C bindings to use libpcap to read packets off the wire.

To use this part, one requires libpcap0.8-dev. Other components may require
other libraries too. Perhaps this library package should Depend: or Recommend:
some of these packages?

(The reasoning is that, if my project uses this package, *even if my code does
not directly call libpcap*, I may need it during the build, but this need is due
to code in this package and not my code.)

libpcap is a bit complex however; upstream does not use stable versions and
Debian specifically has 0.8. Upstream recommends at least 1.1 but a contact of
mine confirmed that his package (HoneyBadger, that depends on this package)
works with the libpcap 0.8 in Debian.
