I am writing Catalyst application which uses Module::Install for module building. I keep all project-related modules in separate directory with local::lib:
eval $(perl -Mlocal::lib=$HOME/work/projects/freevideo)
Recently I've moved to amd64 environment, and 'make installdeps' stopped working:

Everything runs on Ubuntu Natty amd64. Is there any workaround for this?
Solved! CPANPLUS had FTP mirrors written in its configuration, and I was too lazy to properly configure my ftp proxy. After replacing all ftp mirrors with http dependencies were successfully installed.
I had a similar error message : Can't use an undefined value as a symbol reference at /System/Library/Perl/5.12/Net/FTP/dataconn.pm line 54.
From reading Nikita answer, I made these changes to fix it:
sudo vim ~/.cpan/CPAN/MyConfig.pm
in the 'urllist' line: replace ftp by http

I am cpan module which have prerequisite on other module. Is there any process to make sure the module can be installed only after the installation of the prerequisite module while
manual installation of the module.
perl MakeFile.pl
make
make test
make install
Yes. Use a standard build management module like
ExtUtils::MakeMaker or Module::Build, which have conventions to handle prerequisites.
For ExtUtils::MakeMaker, the convention is to pass prerequisite information in the PREREQ_PM argument to the WriteMakefile function. Here's what it might look like:
use ExtUtils::MakeMaker;
WriteMakefile(
NAME => 'My::Module',
AUTHOR => 'Me',
VERSION_FROM => 'lib/My/Module.pm',
PREREQ_PM => {
'Some::Module' => 0.42, # need >=v0.42 of Some::Module
'Some::Other::Module' => 0, # but any version of Some::Other::Module is ok
}
dist => ... ,
clean => ... ,
...
);
I'm trying to script some interaction between a Linux box and an ESXi host, using the VMware Perl library (which appears to call a SOAP service on the ESXi host).
I am getting an error for which I can't find a solution: Undefined subroutine &LWP::Protocol::https::Socket::can_read called at /usr/local/share/perl5/LWP/Protocol/http.pm line 22
I am currently running Net-HTTP-6.03. I did try with Net-HTTP-6.05 but it makes the web-based calls very slow (and subsequent ones also eventually fail, instead with about 1.2MB of XML as the error message) -- which various forums suggest is only resolvable by reverting to 6.03 (via cpan install GAAS/Net-HTTP-6.03.tar.gz).
The crux of my code is as follows:
use VMware::VIRuntime;
my $context = {
options => ParseOptions(), # result of using GetOpts::Long to parse command-line
session => undef
};
$ENV{PERL_NET_HTTPS_SSL_SOCKET_CLASS} = "Net::SSL"; # Suppresses SSL_VERIFY_NONE
if ($context->{options}->{'ignore-ssl-errors'}) {
$ENV{PERL_LWP_SSL_VERIFY_HOSTNAME} = 0; # Ignores certificate errors
}
## next line fails
$context->{session} = Vim::login(
service_url => $context->{options}->{url},
username => $context->{options}->{username},
password => $context->{options}->{password}
);
Is there something else I (can|need to) do to get this working?
I've got it. I needed to reinstall Bundle::LWP from an older version, not just Net-HTTP. Without it, I had LWP v6.05 trying to talk to Net-HTTP v6.03.
Once I realised that LWP == libwww-perl (yes, I'm that new), I found the overall package I needed:
cpan install GAAS/libwww-perl-6.03.tar.gz
Reproduced with LWP 6.05 and Net::HTTP 6.01, which is the cocktail that MacPorts installs at the time of this writing. Upgrading Net::HTTP to 6.06 (current) solved it:
sudo cpan Net::HTTP
I'm trying to install perl modules local to my user - I don't have root access. I have setup in my directory structure the following place for perl libs: /dasd/home/miner/perl5lib/lib/lib (don't ask) - I want my perl modules there.
I am going to foolishly post my whole MyConfig.pm - I think just make_arg, make_install_arg, and make_pl_arg are important, but I spose therein lies my question: I'm not sure exactly how cpan works (and can't easily google it) so I don't know exactly the point of params in MyConfig.pm.

To further explain, I run 'cpan MongoDB', for example, and I get a lot of output, all screaming a bunch of errors, it all dies on this error:

What does "No rule to make target `dasd/home/perl5lib/lib/lib' mean? I don't want to make that dir...I want to make the makefile echoed by cpan when they say this "Writing Makefile for File::Slurp". Which i think I want to be in the /dasd/home/perl5lib/lib/lib directory. I'm assuming we are doing File::Slurp because MongoDB depends on it in some way.
I wish I had a better way to phrase the question - but in short here it is: teach me what this all means - how can MyConfig.pm be changed to do what I want?
"No rule to make target `dasd/home/perl5lib/lib/lib'" means that you put a space between LIB= and dasd/home/perl5lib/lib/lib (when it should have been a /), making them separate arguments. make thinks that dasd/home/perl5lib/lib/lib is the name of a file you want it to build, and it doesn't know how.
I'd start by editing MyConfig.pm in a text editor and just search for LIB= dasd and replace it with LIB=/dasd.
You say your libraries are stored in /dasd/home/miner/perl5lib/lib/lib yet your config file has dasd/home/perl5lib/lib/lib.
You seem to need a leading / and a /miner step in the path.
I have a Perl script that has two dependencies that exist in CPAN. What I'd like to do is have the script itself prompt the user to install the necessary dependencies so the script will run properly. If the user needs to enter in some kind of authentication to install the dependencies that's fine: what I'm trying to avoid is the following workflow:
Run script -> Watch it fail -> Scour CPAN aimlessly -> Lynch the script writer
Instead I'm hoping for something like:
Run script -> Auto-download script dependencies (authenticating as necessary) -> Script succeeds -> Buy the script writer a beer
Can this be done?
Each of the standard build paradigms has their own way of specifying dependencies. In all of these cases, the build process will attempt to install your dependencies, automatically in some contexts.
In ExtUtils::MakeMaker, you pass a hash reference in the PREREQ_PM field to WriteMakefile:
# Makefile.PL for My::Module
use ExtUtils::MakeMaker;
WriteMakefile (
NAME => 'My::Module',
AUTHOR => ...,
...,
PREREQ_PM => {
'Some::Dependency' => 0, # any version
'Some::Other::Dependency' => 0.42, # at least version 0.42
...
},
...
);
In Module::Build, you pass a hashref to the build_requires field:
# Build.PL
use Module::Build;
...
my $builderclass = Module::Build->subclass( ... customizations ... );
my $builder = $builderclass->new(
module_name => 'My::Module',
...,
build_requires => {
'Some::Dependency' => 0,
'Some::Other::Dependency' => 0.42,
},
...
);
$builderclass->create_build_script();
In Module::Install, you execute one or more requires commands before calling the command to write the Makefile:
# Makefile.PL
use inc::Module::Install;
...
requires 'Some::Dependency' => 0;
requires 'Some::Other::Dependency' => 0.42;
test_requires 'Test::More' => 0.89;
...
WriteAll;
You can probably just execute this from inside your script.
perl -MCPAN -e 'install MyModule::MyDepends'
How can I find the standard site_perl (non-arch specific) location? Is it safe to just loop over #INC and find the path ending with "site_perl", or is there a standard way to do this?
The reason for trying to find this, is I have a very large project built up from hundreds of individual modules, all with their own Makefile.PL files (pretty much every .pm file has been built as its own CPAN style module). Along with this, each module may have artifacts (templates, .cgi's, etc), in various locations, all which need to be deployed to various locations, nothing is standard. This is the first step in trying to get this under control, basically having a single Makefile which can find and deploy everything, the next step will be getting it in sensible layout in version control.
I've spent time trying to do this with standard installation tools, but have had no luck.
C:\Temp> perl -MConfig -e "print qq{$_ => $Config{$_}\n} for grep { /site/ } keys %Config"
d_sitearch => define
installsitearch => C:\opt\perl\site\lib
installsitebin => C:\opt\perl\site\bin
installsitehtml1dir =>
installsitehtml3dir =>
installsitelib => C:\opt\perl\site\lib
installsiteman1dir =>
installsiteman3dir =>
installsitescript => C:\opt\perl\site\bin
sitearch => C:\opt\perl\site\lib
sitearchexp => C:\opt\perl\site\lib
sitebin => C:\opt\perl\site\bin
sitebinexp => C:\opt\perl\site\bin
sitehtml1dir =>
sitehtml1direxp =>
sitehtml3dir =>
sitehtml3direxp =>
sitelib => C:\opt\perl\site\lib
sitelib_stem =>
sitelibexp => C:\opt\perl\site\lib
siteman1dir =>
siteman1direxp =>
siteman3dir =>
siteman3direxp =>
siteprefix => C:\opt\perl\site
siteprefixexp => C:\opt\perl\site
sitescript =>
sitescriptexp =>
usesitecustomize => define
Or, as #ysth points out in comments, you can use:
C:\Temp> perl -V:.*site.*
on Windows and
$ perl '-V:.*site.*'
in *nix shells.
Is there a reason not to use one of the module installers (ExtUtils::MakeMaker, Module::Build, Module::Install)?
But if you must, the directory is available (after loading Config) as $Config::Config{'installsitelib'}. Note that some platforms may configure perl such that this directory doesn't literally appear in #INC, instead having some other directory that's symlinked to the installsitelib directory.
Just run perl -V. It will print the default #INC at the end.
It is not safe to loop over #INC as it can be modified by code or the environment, and, therefore, may contain multiple directories that end in site_perl.
If you are trying to determine where a given module is installed use %INC.
