Error while installing Perl modules by auto installation method.

srinietrx · 05-08-2013, 11:47 PM

Hi
I am using BLFS book chaper13 and installing perl module by auto installation method (i.e usingcpan shell and install commands).I am running cpan command for first time.

When I run cpan command it i asks questions like it can do configuration and pick mirror site automatically.When i gave positive answers then error is Can't get tcp protocol by name at /usr/lib/perl5/5.14.0/CPAN/Mirrors.pm line 261.

In Mirrors.pm file line no.261 contains my $ping = Net::Ping->new("tcp",1);
What is wrong.For information I am doing all these in chroot environment.

Did you run the command as root or something like
sudo cpan MY::Module

If not try that.

I found a related thread containing some info here (pretty old)

First of all: You should not be doing this from the chrooted environment! Boot into LFS and work from there and not from your host and the chrooted environment.

If you still run into problems when you do this from LFS: Is your network fully functional?

@j-ray I was in chroot when installing

@druuna Yes,network is not functioning.I will boot into lfs,bring network and give a try
But anyway my task to install perl module was completed by manual method(i.e installing packages directly from cpan website).

Thankyou for reply
