libpcap build error

[git-hulk]

@markuman put -lnl or -lnl-3 to https://github.com/git-hulk/tcpkit/blob/master/src/Makefile#L5 , if failed with missing nl library, try install libnl-dev or libnl3-dev

[markuman]

thx for the fast reply.

core/libnl 3.4.0-1 [installed] was already installed

but unfortunately

@markuman which platform you are running? try to find and install libnl-genl-3-dev

[markuman]

Arch Linux

[git-hulk]

@markuman hi, sorry for the delay so long, I eventually reproduce and fixed it now

[markuman]

@git-hulk thx

now the build is fine without errors. there are just some deprecated notifications

sniffer.c:91:5: warning: 'pcap_lookupdev' is deprecated: use 'pcap_findalldevs' and use the first device [-Wdeprecated-declarations]

and warnings left

/home/m/git/tcpkit/deps/lua/src/loslib.c:107: warning: the use of `tmpnam' is dangerous, better use `mkstemp'

[git-hulk]

@markuman the warning does not affect, I would fix it later. Thanks for your patience, close this issue now.
