OK - I've got the same source as you, but still can't reproduce the problem.

Do you have 64-bit Windows, or 32-bit Windows ?
Is your compiler 64-bit or 32-bit ?

First thing is to concentrate on the contents of pod/perldelta.pod. Does line 5 of that file contain:

perldelta - what is new for perl v5.16.3
It should. Specifically, for me that file begins with:
=encoding utf8 =head1 NAME perldelta - what is new for perl v5.16.3 =head1 DESCRIPTION
If that part's ok then we probably switch our attention to Porting/pod_lib.pl and insert some warn statements just prior to line 117 of that file - that will help us establish the reason that the failure occurs.

Cheers,
Rob

    Thanks Rob!

    I'm on 32 bit XP right now. I originally tried this on a 64 bit Win 7 -- with either archecture, I get the same error though. At least I'm consistent.

    my preldelta matches. It should. I didn't modify it.

    =encoding utf8 =head1 NAME perldelta - what is new for perl v5.16.3 =head1 DESCRIPTION

    I did try to see what is in $contents and nothing was there. If I modify pod_lib.pl like so:

    open Fpod, $filename or die "Can't read $filename: $!"; local $/; my $filepod = <Fpod>; close Fpod; my $contents = $filepod;

    then that gets me past the original problem of "Can't extract version from pod/perldelta.pod"... that is fixed from the code snip just above.

    However, with using that code snippet, it now throws another error later down in pod_lib.pl. At this point, I have an uneasy feeling about chasing modifications to pod_lib code when it has worked for others out of the box.

    Thanks!

      I did try to see what is in $contents and nothing was there.

      Do you have a functioning perl already built on your machine ? If you do, try running the following script. (In that script you'll first need to change $filename to point to the full path to pod/perldelta.pod on your machine.)
      ## script.pl ## use warnings; use strict; my $filename = 'C:/comp/perl-5.16.3/pod/perldelta.pod'; open RD, '<', $filename or die "Can't read: $!"; my @c = <RD>; my $contents = join '', @c; close RD or die "Can't close: $!"; my @want = $contents =~ /perldelta - what is new for perl v(5)\.(\d+)\.(\ +d+)\n/; die "Can't extract version from $filename" unless @want; print "\n@want\n";
      That script should reveal that @want contains (5, 16,3). Is that what you get ?

      Then try running the same script using the perl that you've just built with your compiler. (That perl is located in the top level source folder - ie one level up from the win32 folder.)

      To do that, cd to that top level source folder and run perl /full/path/to/above/script.pl.
      How does that fare ?
      (While you're in that folder, you might also like to check the output of perl -V just to verify that the perl that's being run is, in fact, the one that you've just built. The @INC listing at the end should *not* contain a site/lib directory, and the first directory listed should be in your source tree. )

      Sorry - out of time for tonight, but I can pick this up again tomorrow morning if need be.

      Cheers,
      Rob

        Thanks for the reply... I copied your code and put it in a file called C:\Temp\testme.pl

        That script should reveal that @want contains (5, 16,3). Is that what you get ?

        No, that is NOT what I get. I get the same error as before...

        perl testme.pl Can't extract version from C:/Temp/perl-5.16.3/pod/perldelta.pod at testme.pl line 17.

        Then try running the same script using the perl that you've just built with your compiler. (That perl is located in the top level source folder - ie one level up from the win32 folder.)

        So I change directories to C:\Temp\perl-5.16.3\ and run perl c:/Temp/testme.pl and it works!

        C:\Temp\perl-5.16.3>perl c:/Temp/testme.pl 5 16 3

        While you're in that folder, you might also like to check the output of perl -V

        Here's a dump of perl -V
