Hi Saved,
Apparently, you didn't pass any argument to your script from the Command Line Interface (CLI), when running it. So, your variable @libfiles is empty, thus, when pass to a scalar variable you get the output "0", when printed.
Consider this:
use warnings;
use strict;
use Data::Printer;
my @gn;
p @gn; # print [] i.e empty
print my $c = () = @gn; ## print 0
So to get the desired result, do this from your CLI: perl script.pl --library=foo,bar,baz then press <ENTER> key. using the following as your perl script.
# your script.pl
use warnings;
use strict;
use Getopt::Long;
my @libfiles;
GetOptions( 'library=s' => \@libfiles );
@libfiles = split( /,/, join( ',', @libfiles ) );
print "@libfiles\n";
my $LstCnt = @libfiles;
print "$LstCnt\n";
Output
foo bar baz
3
So, Getopt::Long is not broken after all.

Hope this helps
If you tell me, I'll forget.
If you show me, I'll remember.
if you involve me, I'll understand.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

are good places to start.
