Hi friends,
I ran this program by typing below command

   #!/usr/bin/perl 
#-w
      
     # use strict;
      
   use PDF::OCR2;
   
   my $p           = PDF::OCR2->new('02_ProProInt2nd_Tab01.pdf');
   
   my $text_all    = $p->text;
   my @text_pages  = $p->text;
   
   my $page_object = $p->page(1);

    For sample PDF outputs the text:

    Never disable your warnings and strict pragma. It is one of the PBP. Moreover what you are getting is a warning and not an error.
