I have Perl v5.10. I am trying to install Net::SSLeay 1.30 and Crypt::SSLeay 0.57.
I have already installed OpenSSL 0.9.8e.
For Net::SSLeay 1.30 I followed these steps:
perl Makefile.PL -windows C:\openssl
nmake
nmake test -- test fails
nmake install
perl test.pl
but I got an fatal error as:
D:\perl\Net_SSLeay.pm-1.30>perl -w test.pl
1..20
Can't load 'D:/perl/site/lib/auto/Net/SSLeay/SSLeay.dll' for module Net::SSLeay: load_file:The specified module could not be found at D:/perl/lib/DynaLoader.pm line 203.
at test.pl line 25
Compilation failed in require at test.pl line 25.
BEGIN failed--compilation aborted at test.pl line 25.
I got the same results for Crypt::SSLeay 0.57.
Randy Kobes has an answer for this on the Perl Win32 mailing list. Does your PATH environment variable contain the directory that contains libeay32.dll or ssleay32.dll?
There are many other answers that you can find in Google too. In cases like these, I take the whole error message and shove it into the Google search bar. I start cutting out parts of the error message, such as the specific paths, until I get some search results. This almost always works for me since I'm rarely the first person to have a problem.
Shared libs often have external dependencies, and on some operating systems those dependencies need to be immediately fulfilled when the first shared library is loaded, like your SSLeay.dll, which usually needs the two crypto libs. On linux you can check with ldd the run-time behavior, if all libs are found.
To debug this add the env var PERL_DL_DEBUG=5, like set PERL_DL_DEBUG=5 and try again or use the external tool depends.exe to see what dll's exactly are missing.
I had a similar problem with Windows Par::Packer. The resulting myprogram.exe had trouble loading rurban's hint with PERL_DL_DEBUG
Can't load 'temp\7e717f68.xs.dll' for module Crypt::SSLeay: load_file:Das angegebene Modul wurde nicht gefunden at <embedded>/DynaLoader.pm line 193.
at <embedded>/PAR/Heavy.pm line 95.
I was not able to find out which dlls to include with pp. After these hints I was simply looking to the dll-file with a hex editor and found this string: libgcc_s_dw2-1.dll - this was the dll to include into my "compiled" exe-program:
pp -M Crypt::SSLeay ^
-l c:/strawberry/perl/vendor/lib/auto/Crypt/SSLeay/SSLeay.xs.dll ^
-l c:/strawberry/c/bin/libgcc_s_dw2-1.dll ....
I'm having this same problem with a fresh install of Strawberry Perl 5.30. Googling the error just gives a bunch of unanswered, or half answered questions. Rurban is pointing in the right direction with using depends.exe. Opening ssleay.xs.dll and waiting for it to finishing throwing errors shows 5 main dll's that it depends on. 2 of which are windows core dll's, and 3 from openssl and perl. In the strawberry install, the 2 dll's related to crypto are in the [perlinstallpath]\c\bin folder. Add this to your windows %PATH% variable and it will start working.

I have ActivePerl 5.14.2 on my Windows machine. I have been trying to install the LWP cURL module. I have already installed the libcurl-dev library and GCC on my machine.
I also understand that LWP cURL has a dependency on the WWW-Curl-Easy module. So I installed that too. I installed all these through the command lines using the steps given in the Readme files. I ran the perl makefile.pl command followed by a make and a make install. No errors were given out during the installation.
I am trying to execute this sample code to test my LWP cURL installation:
use LWP::Curl;
use strict;
use warnings;
my $lwpcurl = LWP::Curl->new();
my $content = $lwpcurl->get('http://search.cpan.org','http://www.cpan.org');
I am receiving the below error:
Can't locate loadable object for module WWW::Curl in #INC (#INC
contains: C:/Perl64/site/lib C:/Perl64/lib .) at
C:/Perl64/site/lib/WWW/Curl.pm line 11. BEGIN failed--compilation
aborted at C:/Perl64/site/lib/WWW/Curl.pm line 11. Compilation failed

Compilation failed in require at D:\Varsha\Curl.pl line 1. BEGIN
failed--compilation aborted at D:\Varsha\Curl.pl line 1.
Where am I going wrong?
This is probably not the direction you want to go, but I'd advise you to consider upgrading your perl and changing distributions:
Install Strawberry Perl - 5.18.2.2 is the currently recommended version.
Install cpanm: perl -MCPAN -e "install App::cpanminus"
Install LWP::Curl: cpanm LWP::Curl
I won't bother trying convince you of the change, but Strawberry Perl and cpanm in combination make installing modules a lot easier than having to dealing with the proprietary ppm's of ActivePerl in my opinion.
Just something to consider if you ever get tired of the occasional headaches.
The error means that WWW::Curl is either not installed or its path is not searchable (it's not in #INC). So the solutions are
Make sure that the module is installed.
Add the path where the module is installed to the #INC. Since you are on Windows, you can use set PERL5LIB = c:\path\to\dir
For a permanent solution follow the below:
Right-click My Computer and click Properties.
In the System Properties window, click on the Advanced tab.
In the Advanced section, click the Environment Variables button.
In the Environment Variables window in the "User variables for Foo Bar" section click on New and type in the following:
Variable name: PERL5LIB
Variable value: c:\path\to\dir
Then click OK 3 times. Windows that you open after this will already know about the new variable. Type this in the command window, to see the newly set value:
echo %PERL5LIB%
This will add the private /home/foobar/code directory (or c:\path\to\dir directory) to the beginning of #INC for every script that is executed in the same environment.

I am using CentOS 5.7 perl 5.14.2. While installing CPAN module Task::Catalyst
cpan -i Task::Catalyst
i am getting the error:
http://pastebin.com/N1p1UMAH
3 modules Catalyst::Authentication::Credential::HTTP, Catalyst::View::Email and Catalyst::Plugin::Session::Store::DBIC are giving installation errors
When i tried to manually install the modules , say Catalyst::View::Email
i downloaded the tar file, and then after running the ./Makefile.pl
i got the error
http://pastebin.com/ZSDLtqii
Please suggest?
Makefile.PL is just a perl script, that is generally invoked as perl Makefile.PL, and its output is a regular 'make' style makefile.
Have a look at its contents - perhaps it's been corrupted somehow. In the case of C::V::Email, it should be 39 lines long, and look exactly like this.
I have installed expect module in perl at location C:\strawberry\perl\lib.
As a pre-requisite i have installed IO-Tty module first at same location were perl is installed.
Now if i am doing
use Expect;
It is throwing error
Can't locate IO/Pty.pm in #INC (#INC contains: C:/strawberry/perl/site/lib C:/st
rawberry/perl/vendor/lib C:/strawberry/perl/lib .) at C:/strawberry/perl/lib/Exp
ect.pm line 22.
BEGIN failed--compilation aborted at C:/strawberry/perl/lib/Expect.pm line 22.
Compilation failed in require at croak.txt line 1.
BEGIN failed--compilation aborted at croak.txt line 1.
Possible reasons are
Perl is looking for IO::Pty and IO::Tty module which are called from Expect.pm. But When i have installed IO::Tty module, it is having 2 pm files with names Pty.pm and Tty.pm
package Expect;
use IO::Pty 0.97; # We need make_slave_controlling_terminal()
use IO::Tty;
But perl is looking for IO::Tty module.
Is this causing the issue. If yes then how can i move forward
Expect does not work under Windows.
At least this is my impression when looking at CPAN Resters results. This table here:
http://matrix.cpantesters.org/?dist=Expect;maxver=1
shows that there was never a PASS for Expect under Windows.
Also, the Expect documentation talks about the module not working with ActivePerl and recommends to use cygwin instead:
https://metacpan.org/module/RGIERSIG/Expect-1.21/Expect.pod#Can-I-use-this-module-with-ActivePerl-on-Windows.
I assume that Expect does not work with StrawberryPerl, too.
Did you installed these modules using cpan? - I would highly recommend to install modules only via cpan, so you'll get all the dependencies needed.
If you've done so, try to reinstall it and watch out for any errors.
I tested the install via cpan and it needs to compile the IO::Tty package, so maybe you need to set-up an build environment for any perl modules you would like to install.
If you just copied some precompiled files verify that the files you're missing really exist and download the package again.
Edit:
What I missed - The full path for your Pty.pm and Tty.pm should be something like "C:/strawberry/perl/lib/IO/Tty.pm"
I learnt basisc about Scheme and want to try Guile.
When copied this sample here the first one and run as a script, an Error occured,
$ guile copy.scm
ERROR: no code for module (gnome-2)
My laptop runs Fedora 16 x86_64, with yum install guile*
How to deal with Guile's modules?
May be you need guile-gnome-plataform-devel?
I am trying to get WWW::Mechanize to login to Yahoo using https; however, it requires the use of Crypt::SSLeay for sending over https.
Crypt::SSLeay installed succesfully, and openssl was already installed on the system.
However, it gives the error upon loading:
Can't load '/home/gen19/perl5/lib/perl5/lib/site_perl/5.10.1/i686-linux//auto/Crypt/SSLeay/SSLeay.so' for module Crypt::SSLeay: /home/gen19/perl5/lib/perl5/lib/site_perl/5.10.1/i686-linux//auto/Crypt/SSLeay/SSLeay.so: undefined symbol: PL_sv_undef at /usr/lib/perl5/5.8.0/i386-linux-thread-multi/DynaLoader.pm line 229.
at /home/gen19/lwp4 line 15
Compilation failed in require at /home/gen19/lwp4 line 15.
BEGIN failed--compilation aborted at /home/gen19/lwp4 line 15.
The installation of Crypt::SSLeay was successful, and could recognize the installation of openssl (here):
perl Makefile.PL
=======================================================
Only one OpenSSL installation found at /usr
Consider running 'perl Makefile.PL --default' the next
time Crypt::SSLeay is upgraded to select this directory
automatically thereby avoiding the following prompt.

Which SSL install path do you want to use? [/usr] /home/gen19/ssldir
BUILD INFORMATION

Writing Makefile for Crypt::SSLeay
The test suite can attempt to connect to public servers
to ensure that the code is working properly. If you are
behind a strict firewall or have no network connectivity,
these tests may fail (through no fault of the code).
Do you want to run the live tests (y/N) ? [N]
NOTE: recently installed Perl v5.10.1 using App::perlbrew, due to LWP::UserAgent's needing it. I installed Crypt::SSLeay using my new version of Perl.
I don't have root priveldiges, as I am doing this on a remote server at school. Please tell me why it's giving the error even though it installed succesfully. I know it has something to do with the shared libraries, but the installation recognized them.
SIDE NOTE: my script works fine if I don't say "use Crypt::SSLeay;" at the start, but it gives the error when I use https that it's not a supported protocol, and needs LWP::protocol::https installed. Installing that always fails.
EDIT: Thanks for your help, CJM. Apparently it was using the old version of Perl when I executed, but now I've fixed that.
It doesn't give that error anymore; however, it still says
Error GETing https://login.yahoo.com/config/login_verify2?&.src=ym: Protocol scheme 'https' is not supported (LWP::Protocol::https not installed) at lwp4 line 14
I thought Crypt::SSLeay was supposed to take care of this.
If you examine the error message, you'll notice it mentions both 5.10.1 and 5.8.0 (in the Perl library paths). This indicates that you're trying to use a module built for one version of Perl with a different version. XS-based Perl modules (i.e. ones that include C code) are not binary compatible between major releases of Perl.
It appears you installed Crypt::SSLeay using Perl 5.10.1, and are trying to use it with 5.8.0. That won't work. Use only Perl 5.10.x with that installation. If you need to use it with Perl 5.8.0 also, install another copy in a different directory.
