On most modern Unix systems the ranlib step is already integrated into ar.
I'd guess that only a genuine 4.[23]BSD or SVR1 system would actually need
an
explicit ranlib. Another approach is to use an overrideable RANLIB macro
like so:
RANLIB=ranlib
libxxx.a: a.o b.o c.o
ar r $@ $?; $(RANLIB) $@
On systems that don't need it, invoke make with RANLIB=: and the shell will
ignore it. (Combine the ar and ranlib commands one one line, as above, to
avoid
an unnecessary additional spawn of sh for the possibly unneeded ranlib
invocation...)
