Hi, I am learning about So far I have manage to follow along with the tutorial I believe https://www.boost.org/doc/libs/1_77_0/doc/html/boost_dll/tutorial.html Using tutorial 5 as an illustration https://github.com/apolukhin/Boost.DLL/blob/develop/example/tutorial5/load_a... On this line, I will have the ability to reference the object of my_api_sum I believe https://github.com/apolukhin/Boost.DLL/blob/develop/example/tutorial5/load_a... I have the following questions: 1. If I have a class that is e.g. a shape, say rectangle (of different sizes), what approach may I use to create different instances of the class from the plugin? 2. If my class requires parameters for it's construction, how do I pass it via the shared library loading mechanism ? Or have I been looking to use boost dll shared_library wrongly and that I might look at the plugin being some sort of factory design approach ? Thank you in advance.
