: 'statically' is such an overloaded term I prefer to avoid using it.

: The C linker will include the body of functions defined in non-shared
: libraries into every shared object that references them, AFAIK.  This is
: obvious if you run nm(1) on libbar.so of the example above, because the
: libfoo_init() function is listed as 'T'.  I think that's what you want
: by making the libfoo.a library non-shared in the first place.

Got it!  I recalled something des or phk wrote me a while ago, then I skimmed
the manpage again.  I have to put the .a files AFTER the object files where
the unresolved symbol is found.
