[Solved] Qt 5.3.2 QMYSQL driver not loaded
-
hi !
I've installed in a pc with Mint 17 Qt 5.3.2 with the installer. File libqsqlmysql.so has been generated during installation and it is in the right place. But when I try to connect with mysql db i receive a message "QMYSQL driver not loaded". So, from the source I've generated a new libqsqlmysql.so; the command ldd libqsqlmysql.so has given this output:@
linux-gate.so.1 => (0xb77ab000)

I moved the new libqsqlmysql.so in the right place but doesn't work.
I don't know why it's so difficult and what I have to do; in other pc, with Qt 4.8 it was very very easy to connect with a mysqldb.
Thanks in advance for helping[edit: added coding tags @ for better readability SGaist]

Hi and welcome to devnet,
Did you check the error message from QSqlDatabase ?
-
thank you for your answer;
ok,if I use libqsqlmysql.so from default installation I received this message:@QSqlDatabase: QMYSQL driver not loaded
QSqlDatabase: available drivers: QSQLITE QMYSQL QMYSQL3 QPSQL QPSQL7
@
otherwise, if I use libqsqlmysql.so generated from source no message, but db is not connected. -
Sorry, I was so stupid.... I din't create a test db correctly ....
just only need build libqsqlmysql.so from mysql.pro (qmake, make) in
@Qtpath/5.3/Src/qtbase/src/plugins/sqldrivers/mysql@
and move it from
@Qtpath/5.3/Src/qtbase//plugins/sqldrivers@
in which is created to
@Qtpath/5.3/gcc/qtbase/plugins/sqldrivers@
Good bye ! -
Don't worry that can happen
Since you have it working now, please update the thread title prepending [solved] so other forum users may know a solution has been found :)
