in reply to Workings of UNIVERSAL::can

Suddenly UNIVERSAL::can no longer find a number of taglib functions that were previously visible.

More than likely this nothing to do with UNIVERSAL. Try http://search.cpan.org/~dongxu/Audio-TagLib-1.50_01/

    Not likely to be the problem as that's the source base I'm working on. Although it is true that that distribution does not have my problem.

    Just to be clear, I'm not alleging that UNIVERSAL::can is buggy. If I understand what's it algorithm is -- how it finds out what files it searches to determine if a script 'can', then I can figure out what I'm doing wrong.

    I hope that this clears things up.

      I hope that this clears things up.....

      It really doesn't :)

      Anyway, It just walks @ISA asking if it can, See UNIVERSAL, perlobj, perlboot

        There are no base classes other than UNIVERSAL. In any event, the functions that can't be found are within the C++ library. I have verified that the functions mentioned in the library object (.so) file.
