I'm trying to compile https://github.com/bettercap/bettercap by cloning git repo and running:

$ go version
go version go1.14.4 linux/amd64

Those error seems to be connected with bettercap dependencies but I do have e.g libpcap-dev installed(for amd64 not arm) and I'm able to launch the same command successfully without GOARCH defined. Even If I should put those libraries in ARM version I'm not sure how to do this without breaking my host system.

What operating system and processor architecture are you using (go env)?
