LWP modules	Can't Post

My web server(Linux) don't provide LWP modules and the host manager refuse to install the module for his custome..

I decide to place the module in my own folder and use lib to gain access the LWP

But there are so many versions there..my question is

1. My plan workable?

2. which modules of LWP.pm should I use?

3.It may make use of other modules and its sub method.. so any other LWP:: should I download?

Thanks........

No-one call tell you what module to use unless you tell us what your script is doing.

Re: [RedRum] LWP modules [In reply to]	Can't Post

What I am going to try is just to grab a url page lide following...

Code

  use LWP::Simple;unless (defined ($content = get $URL)) {     die "could not get $URL\n";}

Seemingly I have to download all bundles libwww as the pakage Simple.pm

has to use many other pakages inside the libwww::HTTP:: and others,

so how to do all that

If your web host won't install extra modules from CPAN for you, then I'd seriously consider getting a better web host.

Here:

1. Download the latest version of the package at CPAN.ORG:
(Currently 5.65, the link below is directly to the file)

http://search.cpan.org/CPAN/authors/id/G/GA/GAAS/libwww-perl-5.65.tar.gz

2. Upload the file in BINARY format into your CGI-BIN.

3. Through telnet* run the commands below (one at a time):

gunzip libwww-perl-5.65.tar.gz

tar -xf libwww-perl-5.65.tar

perl Makefile.PL

make

make test

make install

Usually you simply just use the following in your scripts: LWP::Simple
But now you have to use the following to tell Perl where the library is installed:

use lib '/var/www/cgi-bin/libwww-perl-5.65/lib'; (YOUR PATH!)
use LWP::Simple;

Here's a test file, just copy and use as a CGI:
#!/usr/bin/perl
use lib '/var/www/cgi-bin/libwww-perl-5.65/lib';
use LWP::Simple;
$content = get ('http://www.schoolbag.com');
print "Content-type: text/html\n\n";
print "$content";

*= If you dont have Telnet access you can use Fileman.cgi from Gossamer Threads, it's a free admin program and very easy to set-up and use:

That is almost certain to fail as LWP has a large number of dependencies on other modules which may well not be installed.

"That is almost certain to fail"

It worked for me and many other folks at my host. It's better than telling people to find another host.

You can't use make install without being root so unless you were root then it would fail.

If your web host won't install extra modules from CPAN for you, then I'd seriously consider getting a better web host.

It would be an irresponsible web host that would install any possible module or application that might be requested by a customer. A "better web host" would carefully evaluate the request and make an informed decision -- in light of their particular system configuration and constraints -- as to whether or not to install it. Some modules can and should be installed; but there may be perfectly valid reasons why a host would choose not to install every possible module that a customer might want.

The decision regarding which modules to install ought to be made with the same degree of caution that you would apply to selecting programs and scripts to download and install on your web site or your computer.

On the other hand, LWP is a pretty standard module, as are several others. Those modules probably ought to be installed already by any host that claims to support Perl. A host that doesn't support LWP is probably not a good choice for someone who wants to run a lot of Perl scripts, but they may be perfectly fine for other purposes.

Yes, LWP is installed on our servers.

Re: [James] LWP modules [In reply to]	Can't Post

I made a script using LWP to auto-submit to Gossamer-Forum I wonder if I should try it out here Wink

It can make about 20 new threads in a few seconds.

I used it as a bot to reply to people who made posts with CAPS LOCK ON or those swearing.

Sorry to be off-topic.

You don't have to be root to run "make install" as long as you set the PREFIX correctly when you ran "perl Makefile.PL PREFIX=/somewhere/you/can/write/to".
