Installing Crypt::SSLeay 0.72 on Windows

This section provides a tutorial example on how to install Crypt::SSLeay 0.72 for ActiveState Perl on Windows systems.

If you want to write your own Perl program to communicate with an HTTPS Web server, you should install a Perl module to help you. Currently, the best Perl module for HTTPS communication is Crypt::SSLeay, originally developed by Gisle Aas.

Crypt::SSLeay works with the LWP::UserAgent module to allow you to perform GET, HEAD and POST requests with the HTTPS server.

Here what I did to install Crypt::SSLeay:

1. Make sure I have ActiveState Perl installed on my Windows system:

C:\herong>perl -version

This is perl 5, version 26, subversion 1 (v5.26.1) built 
   for MSWin32-x64-multi-thread
(with 1 registered patch, see perl -V for more detail)

Binary build 2601 [404865] provided by ActiveState 
http://www.ActiveState.com
Built Dec 11 2017 12:23:25

2. Run Perl Package Manager "ppm" to download and install Crypt::SSLeay as shown in the picture below:

C:\herong>ppm install crypt-ssleay
ppm install failed: Can't find any package that provides crypt-ssleay

Looks like Crypt::SSLeay is no longer available in the Perl package repository. It was there before.

So I have to install SOAP::Lite using the CPAN shell:

C:\herong>perl -MCPAN -e shell

It looks like you don't have a C compiler and make utility installed.
Trying to install dmake and the MinGW gcc compiler using the Perl Package
Manager.
This may take a a few minutes...

Enter 'h' for help.

Configuring N/NA/NANIS/Crypt-SSLeay-0.72.tar.gz with Makefile.PL

 *** THIS IS NOT AN ERROR, JUST A MESSAGE FOR YOUR INFORMATION ***

 Do you really need Crypt::SSLeay?

 Starting with version 6.02 of LWP, https support was unbundled into
 LWP::Protocol::https. This module specifies as one of its prerequisites
 IO::Socket::SSL which is automatically used by LWP::UserAgent unless
 this preference is overridden separately. IO::Socket::SSL is a more
 complete implementation, and, crucially, it allows hostname
 verification. Crypt::SSLeay does not support this. At this point,
 Crypt::SSLeay is maintained to support existing software that already
 depends on it.

 However, it is possible that your software does not really depend on
 Crypt::SSLeay, only on the ability of LWP::UserAgent class to
 communicate with sites over SSL/TLS.

 If are using version LWP 6.02 or later, and therefore have installed
 LWP::Protocol::https and its dependencies, and do not explicitly use
 Net::SSL before loading LWP::UserAgent, or override the default socket
 class, you are probably using IO::Socket::SSL and do not really need
 Crypt::SSLeay.

 Before installing Crypt::SSLeay, you may want to try specifying a
 dependency on LWP::Protocol::https.

openssl-version.c:2:30: fatal error: openssl/opensslv.h: 
   No such file or directory
compilation terminated.
Failed to build and link a simple executable using OpenSSL
No 'Makefile' created  NANIS/Crypt-SSLeay-0.72.tar.gz
  C:\Perl64\bin\perl.exe Makefile.PL INSTALLDIRS=site -- NOT OK
Failed during this command:
 NANIS/Crypt-SSLeay-0.72.tar.gz: writemakefile NO -- No 'Makefile' created

cpan> exit

Too bad. The installation failed. But the Crypt::SSLeay 0.72 package displayes a message saying It's not needed any more if I use version 6.02 of LWP.
