If you can share more information (e.g. sample code), it would be easier to figure  out the problem. Before that, have you tried QTPLUGIN for the linking failure?

Best regards,

Subject: [Development] How to use Q_IMPORT_PLUGIN macro together with *.pri files?

Hi guys,

I need to create a 'static' plugin for the iOS, using qmake.
A problem is that the qmake can't generate a valid XCode project file, using dependencies.

See, e.g. this bug: https://bugreports.qt.io/browse/QTBUG-71566.
So, I can't use XCode to deliver my application to AppStore.

Instead of using a static plugins I want to include and compile my plugins via
my-plugin.pri files.

But it does not work, because linking failed when I use this code:




with an error, like:

Undefined symbols for architecture x86_64:

"qt_static_plugin_BasicToolsPlugin()", referenced from:

StaticBasicToolsPluginPluginInstance::StaticBasicToolsPluginPluginInstance() in main.o

ld: symbol(s) not found for architecture x86_64

clang: error: linker command failed with exit code 1 (use -v to see invocation)

Is any workaround to avoid this and to use a 'static' plugins in a fom of a *.pri files?
