Whether Qt - Shared C++ Library - can be used by other non Qt applications?

Parvathy2020

I want to create a c++ shared library (.so), which will be used by multiple applications(both qt and non qt ).
But if we create the shared c++ library in Qt, will it possible for other non-qt applications to use the APIs of this library. Will there be any dependency ?

Hi,

Dependency on the Qt module you are using and depending on what you use from Qt, there's the mandatory Q/Core/Gui/Application object.

If you handle anything Qt based in your library and your lib can link the the required Qt modules you should be fine. I have done it on windows a few times for LabVIEW to call it and some of the C# guys as well. If I needed a qt event loop i start it with my library and they have to manage properly closing it when they are done.

@MrShawn Ok thanks for your reply !
My Qt Library uses some of the qt modules like Qt Core, QtNetwork etc. What can be done to resolve the dependency with these Qt modules.

Unless you put the Qt parts behind a private implementation your users will have to link against Qt as well as your library.
