Question

I have tried to install Net::Arping package using cpan and I can’t do that because of errors…

CPAN.pm: Going to build R/RI/RIIKI/Net-Arping-0.02.tar.gz

Checking if your kit is complete...
Looks good

I need this perl module for check_arping script for Nagios.

Some additional informations:

As You see I’ve installed libnet, libpcap and still there are problems … Is anyone have an idea how to resolve this problem?

Answer 1

You have installed libpcap-devel, but not libnet-devel. The *-devel version of an RPM includes C header files that are often required when building XS-based modules.

Try sudo yum install libnet-devel before trying to build the module again.

Update: The advice above was correct, but insufficient. I’ve just tested this on an installation of Centos 5.6 and it fails with exactly the same errors.

Looking at the CPAN testers results, it’s clear that version 0.02 of Net::Arping hasn’t built successfully for anyone for a very long time. This distribution was uploaded to CPAN in 2002 and it appears that its XS code just isn’t compatible with modern versions of libnet.

There is, however, on CPAN a version 0.03 of Net::Arping. This builds successfully on my Centos 5.6. I suggest you switch to using that instead. I haven’t yet worked out why cpan doesn’t recognise version 0.03. I see it’s by a different author, so it might be a permissions problem. You should consider reporting this issue to [e-mail].
