37 # @RETURN: the libdir for the selected ABI
38 # @DESCRIPTION:
39 # This function simply returns the desired lib directory. With portage
40 # 2.0.51, we now have support for installing libraries to lib32/lib64
41 # to accomidate the needs of multilib systems. It's no longer a good idea
42 # to assume all libraries will end up in lib. Replace any (sane) instances
43 # where lib is named directly with $(get_libdir) if possible.
44 #
45 # Jeremy Huddleston <eradicator@gentoo.org> (23 Dec 2004):
46 # Added support for ${ABI} and ${DEFAULT_ABI}. If they're both not set,
47 # fall back on old behavior. Any profile that has these set should also
48 # depend on a newer version of portage (not yet released) which uses these
49 # over CONF_LIBDIR in econf, dolib, etc...

74 # and where lib64 -must- be used on amd64 (for applications that need lib
75 # to be 32bit, such as adobe acrobat). Note that this override also bypasses
76 # portage version sanity checking.
77 # get_libdir_override expects one argument, the result get_libdir should
78 # return:
79 #
80 # get_libdir_override lib64
