I also try to add:
```

But then i get:

(Can't find -ltestlib)

What am I do wrong? How can I link my library with my app?

FYI, `static` has no meaning at module scope.

Did you compile `testlib.d` into a library? I only ask because 
you didn't show a command line for it.

Ok, I replaced abc to abc() string function;

Yes.
My tree:
- Root
     - libs
       - testlib.a
     - source
       - app.d
     - dub.json

testlib.a was build also with DUB where targetType was "library";
