<![CDATA[[SOLVED] Create a shared library without resolving functions or a QPluginLoader interface]]>Hello there

In the past few days I played with shared and static libraries, QPlugin and QPluginLoader. Now I think it's the time to use these information in a project.

The plan: I have an application and a backend (shared library). The shared library contains signal and slots and has more than 250 methods. At the moment I link it statically - so exporting is not a problem.

Now I run into the problem of a shared library:

So as you can see I need the possibility of the QPluginLoader without the interface (Because the plan is to write a shared library and not an abstract plugin interface). My questions:

  • Is it possible to use a shared library without an interface in combination with QPluginLoader. The solution has to work under windows (Unix-only would be very easy)
  • If not, are there any other solutions ?

Thank you in advice,
Threadcore

I have the possibility to link against the (shared) library. I develop both components and deploy both in the same package.

I use CMake as a build system and under Unix is is possible to create a shared library with add_library(xyz SHARED ...) and put them in the library directory - very nice. But this does not work for windows - so that's my problem

Are you planning to give the means to link to your library along your library ?
