Trying to compile MP3::Info gives errors

Hello
I try to compile a perl script into a win32 executable using the PAR
packager. The script uses the module MP3::Info which seems to be the
problem. The smallest code which make the problem is:

#### Perl code in file hello.pl
use MP3::Info;
$mp3InfoHashRef = get_mp3info("C:\123.mp3");
$bitR = $mp3InfoHashRef->{'BITRATE'};
print "bitR: $bitR";
#### End of Perl code


On compile I get

>p2e hello.pl
Processing 'MP3::Info'
Processing 'strict'
Processing 'Carp'
Processing 'Carp::Heavy'
Processing 'warnings'
Processing 'Exporter'
Processing 'Exporter::Heavy'
Processing 'overload'
Processing 'Scalar::Util'

Writing 'my.exe'



Can someone tell me what's wrong?

I guess the first error is for some Macintosh things I am not interested
in (as I'm on win 2000). But I can't figure out the second error. Any
input is welcome.

Thanks and best regards Phil

Re: Trying to compile MP3::Info gives errors

Sorry that code should have been:

#### Perl code in file hello.pl
use MP3::Info;
$mp3InfoHashRef = get_mp3info("C:\\123.mp3");
$bitR = $mp3InfoHashRef->{'BITRATE'};
print "bitR: $bitR";
#### End of Perl code

(forgot the second backslash \\ he he)
But still no difference on the compiling.

[errors snipped]

What is 'p2e' ? I get:

'p2e' is not recognized as an internal or external command, operable program
or batch file.

I tried using one of the mp3 files that come with MP3::Info (as I don't have
C:\123.mp3):

use warnings;
use MP3::Info;
$mp3InfoHashRef = get_mp3info("D:\\comp58_M\\MP3-Info-1.13\\t\\test1.mp3");
$bitR = $mp3InfoHashRef->{'BITRATE'};
print "bitR: $bitR";

When run as a perl script that produces:

bitR: 128

I then built the excutable using PAR's pp utility with:

pp -o hello.exe hello.pl

When I run 'hello.exe' I get the same output:

bitR: 128

That is - I can't reproduce the problem you're facing.

(I'm using PAR-0.90 on Windows2000 with perl 5.8.7.)

Cheers,
Rob

Hello Rob,

Thanks for your answer which brought me to review the whole thing. I
missunderstood what App::Packer does.
I thought it would compile my script in a win32 exe, but it actually
just wraps the script in a bundle and you still need a perl interpreter
on the machine to execute it. So p2e.pl is part of that App::Packer and
has nothing to do with pp from PAR (sorry about that).

I'll try to install PAR and make it work (as a perlcc compilation failed
as well).

Best regards
Phil

Double that backslash please. Or use a forward slash.
