PERL INSTALLATION

I want to connect to mysql using Perl DBI with the following data and code. Oh, by the way I'm using xampp for linux. I've tried to save it on /opt/lampp/htdocs folder, compile it and run it on http://localhost/test.cgi no errors occured but it doesn't print anything except "duhh" on a blue background:-/. I can't connect to mysql...:-( why? Can anybody help me solve this problem?
 
By the way i failed to install DBD:mysql... An error message "can't find mysql.h" was displayed. I tried to locate it using "locate" i cant indeed find this file.. Where could I get this file? Is this related to my problem above?? (DBI installation was, on the other hand, successful)
 
database_name:adventure
user: root
password: sithas
host: localhost
tablename: participant
 
<------------------------------code---test.cgi--------------------------------->

use warnings;

use CGI::Pretty;

use strict;

use DBI();

my $cgi = new CGI;

print $cgi->header();

print $cgi->start_html(

-tilte=>'try',

-bgcolor=>'blue'

);

print "duhh!";

my $dbh = DBI->connect("DBI:mysql:database=adventure;host=localhost","root","sithas", {'RaiseError' => 1});

print "ad";

my $sth = $dbh->prepare("SELECT * FROM participant") or die "query failed";

$sth->execute();

print "sulod";

while (my $ref = $sth->fetchrow_hashref()) {

print "good";

}

$sth->finish();

$dbh->disconnect();

print $cgi->end_html();
