Static linking with MUSL added 2088 bytes of overhead. Likely only the code that was needed.

It's true that without proper care, you might end up importing a whole lot of useless stuff though.




That's great, but can you now demonstrate the same with Qt and KDE, as you claimed above?

FWIW, I believe (but could very well be wrong) the reason that this works this well with MUSL is that every function is defined in its own translation unit. I doubt that Qt and KDE do that.


The library/project has to be designed right. Musl has dummy references that make static linking work without pulling in a bunch of junk. This is very much a language/project issue and I wish more languages actually looked at the huge mess of dep graphs that are needed for simple programs.
