I sorted the lists alphabetically and in = doing so also made it more apparent that libxo isn=E2=80=99t the one = pull in libutil by accident :) (someone went and added libxo before = libutil everywhere so it was hard to know who needed libutil as a first = order dependency instead of as a side-effect of libxo). >>>>=20 >>>> I=E2=80=99ll change the final commit message to reflect that. >>>>=20 >>>> Thanks for the pointers earlier :). >>>>=20 >>>=20 >>> Do keep in mind that ordering can be significant for linking. >>=20 >> How?

Easily > sen with libmd and libcrypto too if I remember right. Also consider libA and libB. Lib B calls something in lib A. If nothing = in the main program calls it, and it is in its own .o, then that .o = won=E2=80=99t get pulled in from the .a, so the symbol won=E2=80=99t get = resolved. This is very definitely true for static libraries. The rules = for dynamic are different, but then Bryan=E2=80=99s example applies. Order matters. Don=E2=80=99t alphabetize just for =E2=80=9Cneatness=E2=80=9D= sake.
