使用内置 MySQL 库静态构建 Qt

Question

I am trying to deploy single-file application using MySQL connection with Qt. And I discovered that app still depends on libmysql.dll . That is because even though qt mysql driver plugin is static, it links to dynamic version of library. I tried configuring Qt with both -qt-sql-mysql and -plugin-sql-mysql ,

Now here's the question: how can I build Qt so mysql library would be built in static qt mysql driver plugin? (or, directly into QtSql )

Answer 1

Use/build a static version of libmysql (put the *.lib file in Qt's lib folder).

Configure with -qt-sql-mysql is enough.

Make sure that the lib is build with the same compiler/linker.
