Hello everybody, I'll try to describe the issue very brief and will add further info, if needed/requested.
Prerequesties Qt 4.8.7 (upgrade is not an option) built with gcc-7.3.1 for an imx25 board linux kernel 4.17.19 the need to use "attach" and "detach" inside transactions and therefor using "- system-sqlite" with a newer version of libsqlite (greater than 3.21.0 released on 2017-10- 24) Description / observed behavior The code that uses "attach" and "detach" inside transactions runs every 15min (copies data from in-memory sqlite files to sqlite files on persistent storage). This is never reached, since the system is restarted via watchdog every (roundabout) 10 minutes. In this time the system collection various data from various I/O. Qt with built in sqlite (3.7.7.1) -> system works as expected Qt with '-system-sqlite' and libsqlite 3.7.7.1 -> system works as expected Qt with '-system-sqlite' and libsqlite 3.21.0 -> system slows down till reboot via watchdog Qt with '-system-sqlite' and libsqlite 3.24.0 -> system slows down till reboot via watchdog Are there any known incompatibilites between Qt and libsqlite versions? Or maybe compilte time flags that could should be added? Any suggestions howto enclose the issue? Thx for your time and interest.
