set_errcall function signature has changed in db4.3 API. See #10025 at http://gd.tuwien.ac.at/db/bdb/changelog-4.3.XX.html With my patch xca will compile with both db4.2 and db4.3.
Created attachment 100655 [details, diff] xca db4.3 API compatibility patch
Thanks. I've added a little different patch, check if OK. If you like xca so much, please try to find responsive upstream, we cannot keep supporting this software this way for much longer.
Your patch is working. I send mail to xca author with the patch. Will see if he responds.
Thanks! If you catch him, please forward all xca patches... There are gcc4, openssl, qt and db...
