you do a regex on your filehandler and not it content :)
try 

#!/usr/bin/perl

use strict;
use warnings;

     print "searching using regexp...";
     
open(my $in,  "<",  "DirectX.log")  or die "Can't open DirectX.log: $!
+";
     
while (<$in>) { # assigns each line in turn to $_
   print "Just read in this line: $_";
   if ($_ =~ /eroare/) {
     print "found eroare on line nr: $.\n";
   }
}

close $in or die "$in: $!";
