Hi, I'm learning D (obliviously) and I can't understand how exactly dependencies work. I haven't found answers to my questions in documentation (or i did't understand it), so can someone answer to mine questions?

1. Does dub compile dependencies as separate binaries? And if yes how to specify where should be they placed?
2. It is possible to compile subpackage as a dynamic or static library and link it to main binary file? Or just better create separate dub package and use it as dependency?

For all answers thank You in advance.
Also sorry for mine English. I'm still learning it. So if I made some grammatic mistakes point them :)

Object/static files, but yes.

Where they go:

Windows: %APPDATA%/roaming/dub
Posix: ~/.dub

You don't need to change this and if you think you do, you're wrong :)

Static yes, dynamic it won't link against (some bug last I heard).
Have to do that manually.

"dependencies": { "mypackage:subpackage": "*" }

Change as required for SDL.

Except when you need to:
https://github.com/dlang/dub/issues/1305
dub build --compiler=ldmd2 overwrites files in ~/.dub written by dub build #1305

learning D in an oblivious manner can be difficult ;-)

At first thanks for answers.
So going back to my first question. Code from dependencies is compiled with mine project to one single executable?
