Initial Analysis: - stemmer can be set at the configure step, but it isn't by d/rules (default is auto) - providing libstemmer-dev converts the auto to a yes (as happened in the ubuntu3 version) - that yes then builds the code that is missing regarding this error here - but also builds the stemmer dependency into dovecot-core (main) - textcat is also not given by rules and defaults to auto (yes, due to exttectcat being a build dependency) - plugin config "no_snowball" is no workaround as it fails already at ld.so
Checking Sources and Build: - Build logs should be free of Snowball, but aren't => even without libstemmer I still see snowball reference - BUILD_FTS_STEMMER guards inclusion of Snowball.cc in fts-lucene/Makefile.am - But due to complexities in automake BUILD_FTS_EXTTEXTCAT_TRUE guards Snowball.cc in fts-lucene/Makefile.in eventually I wondered if this is a Regression at all?: - <=vivid had dovecot 2.2.9 which didn't have the lucene plugin - >=wily had lucene in the currently failing form Options for us: 1. - drop textcat dev from build deps, but that will also remove other functionality e.g. lib-fts/fts-language.c => No, we don't want to cut other parts of dovecot 2. - get libstemmer into main to make the runtime dependency a no-issue => No, not reasonable for this alone 3. - try to guard the critical code via libstemmer instead of libtextcat (possible but complex for us not owning/used to that code) => Maybe (could be done, but likely error prone) 4. - drop lucene plugin => This would be my choice, especially since: - lucene is deprecated in favor of solr by the dovecot project - and it never worked since it's appearance in Ubuntu Obviously this is up for discussion ... -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1524526 Title: Crashes with undefined symbol To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/dovecot/+bug/1524526/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
