It might be a good idea to support selecting between libraries at compile time; I'm not going to comment on that. But what you are proposing here made me speechless for a while. What is "choose at runtime" even supposed to mean? Do you link to all of them and then control into which one the code actually calls? Do you dl_open() the one you want to use when the application starts? I can't see how this can possibly work. Or rather: Any solution I can think of requires a lot of abstraction code probably causing enough overhead to make the exercise pointless. But really: What's the point of choosing the event loop implementation at run time? If there is something for the distribution user to choose from, then clearly multiple options are available in the distribution. So why not just pick one at compile time? If you really insist on making the event loop implementation selectable (probeable?) at runtime, then I think the only viable approach is to move all your event loop facing code into a separate module and compile this module multiple times - once per event loop supported. Then the right instance of the module can be dynamically linked at run time by either having the right symlinks in place or dl_open().
