CPAN cannot install Math::Pari module

bluethundr · 06-08-2010, 01:01 AM

greetings

I wrote a perl script to feed information to our load balancer:

Code:

#!/usr/bin/perl
#
use strict;
#use warnings;
#
#
use Net::SSH::Perl;
my $user="bluethundr";
my $pass="secret";
my $dir="$ENV{HOME}/data";
open (LBVSERVERS), '<', "$dir/lb-vserver" or die "Couldn't open file: $!";
open (CSVSERVERS), '<', "$dir/cs-vserver" or die "Couldn't open file: $!";


my $ssh = Net::SSH::Perl->new("10.50.0.1");
$ssh->login("$user", "$pass");

print "\n\n\n\n\n**********LB VSERVERS**********\n\n\n\n\n";  
while (my $line = <LBVSERVERS>) {
      chomp $line;
      my ($number,  $lbvserver) = split(/\s+/, $line);
      print "show lb vserver $lbvserver\n";
      $ssh->cmd("show lb vserver $lbvserver");
      chomp(my $ans = <STDIN>);
      print "Ready for next lb vserver? (y/n): ";
      if ($ans=~/y|Y/) {
        next;
      } else {
         chomp(my $done = <STDIN>);
         print "Quit? (y/n): ";
         if($ans=~/y|Y/) {
           last;
         } else { 
         next;
         }
       }
         
      
      
print "\n\n\n\n\n**********CS VSERVERS**********\n\n\n\n\n";
while (my $line = <CSVSERVERS>) {
      chomp $line;
      my ($f1,  $f2, $f3, $csvserver) = split(/\s+/, $line);
      print "show cs vserver $csvserver";
      $ssh->cmd("show cs vserver $csvserver");
      print "Ready for next cs vserver? (y/n): ";
      if ($ans=~/y|Y/) {
        next;
      } else {
         chomp(my $done = <STDIN>);
         print "Quit? (y/n): ";
         if($ans=~/y|Y/) {
           last;
         } else { 
         next;
         }
       }
 }
}


close   LBVSERVERS;
close   CSVSERVERS;

I need to be able to install the Math::Pari CPAN module in order to accomodate the Net::SSH CPAN module.

The prereqs are installed:

Code:

cpan> install Net::FTP
Net::FTP is up to date.

cpan> install LWP::UserAgent
LWP::UserAgent is up to date.

But when I either try to install or force install Math::Pari this is what I get:

Code:

cpan> install Math::Pari

  CPAN.pm: Going to build I/IL/ILYAZ/modules/Math-Pari-2.01080604.tar.gz

Did not find GP/PARI build directory around.

Do you want to me to fetch GP/PARI automatically?

  (If you do not, you will need to fetch it manually, and/or direct me to
   the directory with GP/PARI source via the command-line option paridir=/dir)

Make sure you have a large scrollback buffer to see the messages, or `tee'
the STDOUT/STDERR to a file.

Fetch? (y/n, press Enter) y
Getting GP/PARI from ftp://megrez.math.u-bordeaux.fr/pub/pari/unix/
Cannot list (Failed to establish connection.
):  at utils/Math/PariBuild.pm line 319, <STDIN> line 1.

Can't fetch file with Net::FTP, now trying with LWP::UserAgent...
You do not have LWP::UserAgent and/or HTML::LinkExtor installed, cannot download, exiting...

I would certainly appreciate some help past this sticking point.

It sounds like the code is unable to connect via FTP to megrez.math.u-bordeaux.fr site.
When I open the FTP URL (e.g. in FTP client or browser), I can see the contents.

Could you try the same?
Perhaps even fetch the source manually and use the paridir=... option as suggested?
This could help in starting to sort out the connection issue.

HTML::LinkExtor

Maybe you could try this one too?

Hi,

it's a pretty old thread here, but I'm hitting the same problem.

In my case, the domain 'megrez.math.u-bordeaux.fr' seems to be not reachable. I tried it with deifferent tools (FTP and HTTP) and on different networks (DSL and mobile) with same result. Does anyone have an idea, if there is an alternative to get Math::Pari installed without the files from the failing domain (I'm a very beginner with perl an CPAN).

My search on web didn't get me further yet...

Thanks for your hints in advance!

The server was down... Now it seems to be back and the installation works as expected.

@bruz - Welcome to LQ and the Programming forum!

Indeed, this is an old thread. It is generally preferable to start your own thread for two important reasons:

1. Even though your case may seem very similar, your own thread assures that the discussion is constrained to the particulars of your own case which makes it easier for those offering help and all future visitors to follow without being sidetracked by differences - in either thread.

2. Your new thread will be automatically bumped to guarantee it is visible to current members, whereas the old thread, and your question, will disappear into the mists of time!

But no harm done, and thanks for reporting your ultimate success!
