The thread is about dealing with garbage collection when calling julia from C but the first post has a good example of loading a module from C (C++ actually but I think everything there works in C) and then calling a function from that module. I’ve used that approach to call my own modules from C. As far as I can tell loading modules is not in the embedding documentation though so I’m not su…

> Well, I am going to describe what I did here, because I am finding very difficult to obtain clear information about the process of embedding Julia into C++ (when I get better, I will submit a PR to improve the documentation). (Please, correct me if I am wrong!) In fact, Julia will not GCed a variable if it is referenced somewhere. Since I want a variable inside a C++ class to not be freed, I need to make it global or add it reference to a global object. Since the second option seems better, I …
