I have tried all possible StackOverflow answers, no one works for me.

It wasn't really set up to create dylibs. I removed the build of the shared library from the Makefile, so you should now be able to build the program and static library. I'd welcome a Makefile revision to create a dylib.

@jgm Thanks for the reply.

But it seems that there is error occurred in linking. And I cannot build executable, either.

Builds fine for me on El Capitan. (Pull the latest from the repository, then try make distclean and then make, just to make sure.)
