[Interest] QtPlugins statically linked not loading

[Nuno Santos]

Ulf,

Thanks for your reply.

When I built Qt statically I had used this line:

configure -prefix /Users/nsantos/Qt/5.4/clang_32_static -platform macx-clang-32 -commercial -release -static -nomake examples -nomake tests -opengl desktop -skip webkit -skip multimedia -D QT_QML_NO_DEBUGGER

I had to use -DQT_QML_NO_DEBUGGER because there was an issue when linking a project using QtQml:

Undefined symbols for architecture i386:
 "QTcpServerConnection::QTcpServerConnection()", referenced from:
     QQmlDebugServerThread::run() in libQt5Qml.a(qqmldebugserver.o)
ld: symbol(s) not found for architecture i386

Do you think there is a relation between these two problems?

Thanks,

Regards,

Nuno

Mind that this way your application has the QML debug server built in and whenever you start it with the right arguments or call QQmlDebuggingEnabler::startTcpServer() it will open a debug port and accept connections from anywhere. With a dynamically linked Qt you have the option to delete the plugin in order to prevent this.
