mysql library, not a Qt plugin

Sten

Hi, I'm having no success in installing the mysql driver plugin. Using SDK 10.14 on MacOS (reverted back from 10.15), Qt 5.13.1.

After running

~/Qt/5.13.1/clang_64/bin/qmake "INCLUDEPATH+=/usr/local/opt/mysql@5.6/include/mysql" "LIBS+=/usr/local/opt/mysql@5.6/lib/libmysqlclient.18.dylib" mysql.pro

Everything compiles except for -framework MobileCoreServices -lm -framework UIKit in the Makefiles.

After removing these frameworks and compiling I get this error:

QMachOParser: '/Users/sten/Qt/5.13.1/clang_64/plugins/sqldrivers/libqsqlmysql.dylib' is not a Qt plugin

Any help with that?

Hi and welcome to devnet,

What do you get if your run otool -L libqsqlmysql.dylib ?

Thanks for the quick response. This is otool -L:

I would rename mysql@5.6 to something like mysql_5.6. I think that using the @ char there might be wreaking havoc.

@SGaist
I changed the name of mysql@5.6 to mysql5.6 but still Qt does not recognise the plugin.
Even if I can recompile sqlite and other plugins without problem, it does not work for mysql. Any recommendation?

Start your application with the QT_DEBUG_PLUGINS environment variable set to 1.

It might give you more clues about what is happening.
