Error while statically linking libpcap.a to gopacket app

[bsomani]

Hi All,

I am trying to statically link the libpcap.a to my app which is calling gopacket API's
I tried with below command,

LDFLAGS='-l/usr/lib/x86_64-linux-gnu/libdbus-1.a -l/usr/lib/x86_64-linux-gnu/libpcap.a' CGO_ENABLED=1 go build -ldflags '-linkmode external -extldflags -static' -o client cmd/client/main.go

but I am getting below error

Is there anything I am missing here?
