15# has_multilib_profile:
16# Return true if the current profile is a multilib profile and lists more than
17# one abi in ${MULTILIB_ABIS}. You might want to use this like
18# 'use multilib || has_multilib_profile' until all profiles utilizing the
19# 'multilib' use flag are removed from portage
20
21# is_final_abi:
22# Return true if ${ABI} is the final abi to be installed (and thus we are
23# on our last run through a src_* function.
24
25# number_abis:
26# echo the number of ABIs we will be installing for
27
28# get_abi_order:
29# Return a list of the ABIs we want to install for with
30# the last one in the list being the default.
31
32# get_all_libdirs:
33# Returns a list of all the libdirs used by this profile. This includes
34# those that might not be touched by the current ebuild and always includes
35# "lib".
36
37# get_libdir:
38# Returns the libdir for the selected ABI. This is backwards compatible
39# and simply calls get_abi_LIBDIR() on newer profiles. You should use this
40# to determine where to install shared objects (ex: /usr/$(get_libdir))
41
42# get_abi_var <VAR> [<ABI>]:
43# returns the value of ${<VAR>_<ABI>} which should be set in make.defaults
44#
45# get_abi_CFLAGS:
46# get_abi_CDEFINE:
47# get_abi_LIBDIR:
48# Aliases for 'get_abi_var CFLAGS', etc.
49
50# get_ml_incdir [<include dir> [<ABI>]]
51# include dir defaults to /usr/include
52# ABI defaults to ${ABI} or ${DEFAULT_ABI}
53#
54# If a multilib include dir is associated with the passed include dir, then
55# we return it, otherwise, we just echo back the include dir. This is
56# neccessary when a built script greps header files rather than testing them
57# via #include (like perl) to figure out features.
58
59# prep_ml_includes:
60# Some includes (include/asm, glibc, etc) are ABI dependent. In this case,
61# We can install them in different locations for each ABI and create a common
62# header which includes the right one based on CDEFINE_${ABI}. If your
63# package installs ABI-specific headers, just add 'prep_ml_includes' to the
64# end of your src_install(). It takes a list of directories that include
65# files are installed in (default is /usr/include if none are passed).
66#
67# Example:
68# src_install() {
69# ...
70# prep_ml_includes /usr/qt/3/include
71# }
72
73# create_ml_includes <include dir> <symbol 1>:<dir 1> [<symbol 2>:<dir 2> ...]
74# If you need more control than prep_ml_includes can offer (like linux-headers
75# for the asm-* dirs, then use create_ml_includes. The firs argument is the
76# common dir. The remaining args are of the form <symbol>:<dir> where
77# <symbol> is what is put in the #ifdef for choosing that dir.
78#
79# Ideas for this code came from debian's sparc-linux headers package.
80#
81# Example:
82# create_ml_includes /usr/include/asm __sparc__:/usr/include/asm-sparc __sparc64__:/usr/include/asm-sparc64
83# create_ml_includes /usr/include/asm __i386__:/usr/include/asm-i386 __x86_64__:/usr/include/asm-x86_64
