Undefined Reference To Vtable For C++
Plugin: \'vtable constructor failed: idx_circular_layer_geom\' (/mapnik/tests/visual_tests/ styles/../data/text-data-binding.sqlite)\nFull sql was: \'SELECT geom,id,[alignment],[color1],[color2],[color3],[double],[placement],[text1],[text2] FROM circu lar_layer WHERE id IN (SELECT pkid FROM "idx_circular_layer_geom" WHERE xmax>=-1 AND xmin<=1 AND ymax>=-1 AND ymin<=1)\'',)) Mapnik member talaj commented Oct 12, 2014 I found where the problem is finally! Shared cache in SQLite datasources should not be used with SQLite prior to 3.7.15. There are concurrency issues, see "Bug fix: Avoid undefined reference to vtable for class c++ various concurrency problems in shared cache mode.": https://www.sqlite.org/releaselog/3_7_15.html I was comparing SQLite 3.7.15 with 3.7.14. The 3.7.14 fails on vtable constructor failed , 3.7.15 works fine. I would update version to 3.7.15 in https://github.com/mapnik/mapnik/blob/master/plugins/input/sqlite/sqlite_connection.hpp#L58 Mapnik member springmeyer commented Oct 12, 2014 Aha! nice find. Please feel free to commit that change and close this up. springmeyer added this to the Mapnik 3.x milestone Oct 12, 2014 Mapnik member springmeyer commented Oct 12, 2014 Would be worth backporting to 2.3.x as well I think.

Undefined Reference To Vtable For Destructor
I think this is a bug... If you trying to create FTS3/FTS4 table, make sure that column

See the first paragraph under the second example block here: http://www.sqlite.org/fts3.html#section_1_4Docs should be updated to say that you can't create a column with the same name as the table.

The following table creation fails under latest release : > > CREATE VIRTUAL TABLE foo USING FTS3 > ( > bar TEXT, othercolumns TEXT, > CHECK(1), CHECK(1) > ); > > Error message: vtable constructor http://osdir.com/ml/sqlite-users/2010-08/msg00600.html failed Maybe it thinks the two "CHECK(1)" identifiers represent a duplicate column name. CHECK constraints will not work with either fts3 or rtree virtual tables. If they are parsed at all, they will probably not do what you are expecting.

Thank you for your answer. I now am aware that checks must be done by the upper-level application. Benoit On Mon, Aug 30, 2010 at 08:19, Dan Kennedy
