in reply to problem finding symbol in XS-created .so

$id3 = Audio::TagLib::FileRef->new( 't.mp3' );

But fileref.xs defines functions (such as new) that are in package "TagLib::FileRef", *not* package "Audio::TagLib::FileRef". What happens if you recode that line to: 
$id3 = TagLib::FileRef->new( 't.mp3' );

    It also defines a fix for that 
    sub xs_c {
    my $cmd = shift->SUPER::xs_c(@_);
    $cmd .= << 'END';
    sed -i -e 's/newXSproto("TagLib/newXSproto("Audio::TagLib/g' $*.c
    sed -i -e 's/XS(boot_TagLib)/XS(boot_Audio__TagLib)/g' $*.c
END
    return $cmd;
}

      I'm sory, but I have no idea how this code relates to my problem.

    Can't locate TagLib/FileRef.pm in @INC ...

      No ... you still use Audio::TagLib; (Update: not use Audio::TagLib::FileRef as I had first written) but, instead of $id3 = Audio::TagLib::FileRef->new( 't.mp3' ); you have $id3 = TagLib::FileRef->new( 't.mp3' );
      I don't really know whether that will work - I'd probably rather try changing the package name in fileref.xs to "Audio::TagLib::FileRef", but I don't know whether that will work, either :-)
      The module looks to me like a dog's breakfast

      I'll see if I can get anywhere with it on Windows and get back. In the meantime, just try anything you can think of.

        Thanks for getting me one step further.

        Well ... the latest version of the taglib library (1.6.3) builds straight out of the box on MS Windows, but look what happens when one attempts to build Audio::TagLib: 
        ...
ONLY support TagLib version 1.4.*
MSWin32 is not supported currently at Makefile.PL line 11
        main::BEGIN() called at Makefile.PL line 22
        eval {...} called at Makefile.PL line 22
...

        Sorry - lost interest. What version of the taglib library are you using ?

        Cheers,
        Rob
