Does gcc link program with static or dynamic library by default?

Question

I have both static and dynamic versions of the same library installed on my Linux system:

/usr/lib/libsample.a
/usr/lib/libsample.so

Which one of these libraries will use gcc, if I set argument -lsample ?

gcc xxx.c -lsample

How can I force gcc to use static or dynamic version of the library

You don't have to do anything, dynamic is the default.

However, it has to add a couple of things to the binary to help it, at runtime, to properly use the dynamic library.
