meta/recipes-qt/qt4/qt4.inc DEPENDS on sqlite3, but QT_SQL_DRIVER_FLAGS does not specify '-system-sqlite', so Qt is built with a statically linked, Qt supplied version of sqlite3. If we choose to use the system sqlite3, and do so in QT_SQL_DRIVER_FLAGS, you may wish to update the copied-pasted-and-modified QT_SQL_DRIVER_FLAGS in meta-oe's bbappend.
Fix merged to master: http://git.yoctoproject.org/cgit/cgit.cgi/poky/commit/?id=e6053e55f46cae1d3f1e68bd0c61ebe7cac7d165 FWIW, I hope to eliminate the meta-oe bbappend entirely (see recent discussion on the OE mailing lists.)
-the -system-sqlite flag is set -all qt4 recipes build successfully Verified in master:595e92c76700306f9ff8fcf1557eb7ade1f3e907
