Hi, AIX uses a very different format for handling of shared libries, especialy you need special symbol files while linking. I am not an AIX guru so I ca't really say what's wrong without having access to an AIX system. The problem we have is that in addition to the symbols from Perl Embperl also links in symbols from mod_perl and Apache. There must be a apropriate symbol file for Apache and mod_perl at link time.
