Best way to generate library ?

[Lordful]

Hello,

I'm new at c++/Qt programming and I'm searching what is the best way to generate a library from a Qt project ?

It seems that there is different possibilities over internet to build a library, but I can't choose which approach is the best for me.

I must generate a library from a Qt project and then, I will use objects of this library in an other Qt project but I don't know if I must create a static library, a dynamic or a shared ..

Thanks for your help and your explanation

Hi
It depends on your requirements

If you are not sure, I would go with dynamic/shared.

So maybe I can ask

Why do you need to make library ?

Thanks for your answer.

I need to make a library because I created a module on an independent project and now, I must add this module to an application.

I will check what you sent me.

hi
Qt has a system for loading dynamic library's in a platform independent way.
Its called plugins-

Please notice this term is used both for extending Qt tools and for extending
an Qt applications.

and

Hum ok so I can extend a Qt applications with a plugins which will load my dynamic library, am I right ?

@Lordful
well the plugin IS the library.
and plugins can be loaded dynamically.
So yes.

please see
http://doc.qt.io/qt-5/qtwidgets-tools-echoplugin-example.html
for really basic sample
here a string is returned from library.
Could have been anything. including UI and classes.
