CPAN installing Net::Pcap and Packet module failed due to lpcap

Question

Recently, I tried to install perl module Net::Packet and Net::Pcap through cpan but it complained that it cannot find pcap library. So I was searching if cpan would accept e

Answer 1

On Ubuntu, just install libnet-pcap-perl.

Answer 2

This fixed my issue:

yum -y install perl-Net-Pcap libpcap-devel

Answer 3

The README file for Net::Pcap shows how to tell Makefile.PL where to find the pcap library:

perl Makefile.PL INC=-I/opt/local/include/pcap LIBS='-L/opt/local/lib -lpcap'

(I've inserted your paths into the example.)

However, getting the cpan shell to pass those arguments to Makefile.PL is rather more complicated. You'd have to use the Distroprefs system and create a YAML file to supply the arguments. If you're not already familiar with Distroprefs, it'll probably be easier to just install Net::Pcap by hand.
