Re: [gtkmm] dynamic loading

Thanks for your answer.

Sorry, I would say that dlopen() and g_module*() are written in C.
I need to use C++ code, but I thought that functions declared with extern
"C" must be written in C. I didn't know that they could be written in C++,
so it's ok for me now.

I also found a lot of info I need here:
