Data::Alias won't work on some platforms (notably Win32, but also AIX, OS/2, classic MacOS) because I need to invoke functions which aren't exported. Most platforms don't care, but some - the aforementioned - strictly enforce the export list. Any chance some symbols might be exported to allow D::A to work? I'm still checking, but it appears I need at least the following: Perl_av_reify Perl_cxinc Perl_lex_end Perl_mod Perl_op_clear Perl_pop_return (not needed for 5.9.2 or later) Perl_qerror Perl_setdefout Perl_vivify_defelem Perl_yylex - xmath -- Matthijs van Duin -- May the Forth be with you!Thread Next
