Does Qt use Sql?

[ravas]

The project I'm working on doesn't appear to use Sql;
however, when I run macdeployqt it will add
Frameworks/QtSql.framework
PlugIns/sqldrivers
to the APP bundle.

Any ideas on why that happens?
Adding
QT -= sql
to the .pro doesn't change anything.

Maybe you are depending on something that in turn depends on QSql?

Not that I can find.

Something else I don't understand is macdeployqt outputs:

WARNING: Plugin "libqsqlodbc.dylib" uses private API and is not Mac App store compliant.
WARNING: Plugin "libqsqlpsql.dylib" uses private API and is not Mac App store compliant.

I am fairly certain that QtHelp uses Sqlite (but not Mysql, ODBC, or Postgresql). You should remove the drivers for database backends other than Sqlite from the sqldrivers that macdeployqt wants to package.

[ravas]

Chris, you were right.

Removing QtHelp actually drops 3 other frameworks:
- QtCLucene
- QtNetwork
- QtSql

...and also 6 qt plugins.

Qt SQL is an essential module which provides support for SQL databases. Qt SQL's APIs are divided into different layers: SQL API layer, User interface layer
