Subject: [PATCH] Fix for c3 mro failures
Download (untitled) / with headers
text/plain 550b
With perl using c3 as default mro (cperl), we need to use mro dfs explicitly, until the ISAs can be fixed. With c3 as default mro the following failures appear: Inconsistent hierarchy during C3 merge of class CPAN::SQLite::DBI::Search: current merge results [ CPAN::SQLite::DBI::Search, ] merging failed on CPAN::SQLite::DBI at /usr/local/lib/cperl/5.25.3/parent.pm line 22. BEGIN failed--compilation aborted at lib/CPAN/SQLite/DBI/Search.pm line 35. Compilation failed in require at -e line 1. -- Reini Urban

mro doesn't exist in 5.6 or 5.8. I'm not really familiar with cperl, is there any other way to solve the problem without losing backward compatibility with older Perls? -- Serguei Trouchelle
