Things aren't always this cut and dry. For one thing, making a dynamic library out of it isn't usually feasible since mach-o's use of dynamic libraries leaves a lot to be desired. I'm referring to the install name of a library being required to be compiled into the application. If you want to distribute your application, not only do you have to distribute the dynamic library with it but also install it in the same location.

Look for @executable_path/ and @loader_path/ in the documentation, you can install dynamic libraries at paths relative to the application (or with Mac OS X 10.4 and later, relative to each other) using these as part of the install_name.

I didn't know about @loader_path, but I have used @executable_path for frameworks. I figured that it would work for dynamic libraries but if I'm going to the trouble of setting that, I might as well just make a framework out of the library. (I'd rather deal with configuring Xcode projects than working with the autotools in most cases.)


Actually, I suppose that's not entirely true, I could just build the library and use install_name_tool. I think that it might still pick up an installed library and use that instead, though.
