An example - libncurses.so -

#ldd /usr/lib/libncurses.so
        libc.so.6 => /lib/libc.so.6 (0x40068000)
        /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x80000000)

libncurses.a -

#ldd /usr/lib/libncurses.a
ldd: warning: you do not have execution permission for `/usr/lib/libncurses.a'
        not a dynamic executable

If a library has been linked wrong then it wont react right.

The first is a dynamic library - the second isnt.
