14# has_multilib_profile:
15# Return true if the current profile is a multilib profile and lists more than
16# one abi in ${MULTILIB_ABIS}. You might want to use this like
17# 'use multilib || has_multilib_profile' until all profiles utilizing the
18# 'multilib' use flag are removed from portage
19
20# is_final_abi:
21# Return true if ${ABI} is the final abi to be installed (and thus we are
22# on our last run through a src_* function.

25# echo the number of ABIs we will be installing for
26
27# get_install_abis:
28# Return a list of the ABIs we want to install for with
29# the last one in the list being the default.
30
31# get_all_abis:
32# Return a list of the ABIs supported by this profile.
33# the last one in the list being the default.
34
35# get_all_libdirs:
36# Returns a list of all the libdirs used by this profile. This includes
37# those that might not be touched by the current ebuild and always includes
38# "lib".
39
40# get_libdir:
41# Returns the libdir for the selected ABI. This is backwards compatible
42# and simply calls get_abi_LIBDIR() on newer profiles. You should use this
43# to determine where to install shared objects (ex: /usr/$(get_libdir))
44
45# get_abi_var <VAR> [<ABI>]:
46# returns the value of ${<VAR>_<ABI>} which should be set in make.defaults
47#
48# get_abi_CFLAGS:
49# get_abi_CDEFINE:
50# get_abi_LIBDIR:
51# Aliases for 'get_abi_var CFLAGS', etc.
52
53# get_ml_incdir [<include dir> [<ABI>]]
54# include dir defaults to /usr/include
55# ABI defaults to ${ABI} or ${DEFAULT_ABI}
56#
57# If a multilib include dir is associated with the passed include dir, then
58# we return it, otherwise, we just echo back the include dir. This is
59# neccessary when a built script greps header files rather than testing them
60# via #include (like perl) to figure out features.
61
62# prep_ml_includes:
63# Some includes (include/asm, glibc, etc) are ABI dependent. In this case,
64# We can install them in different locations for each ABI and create a common
65# header which includes the right one based on CDEFINE_${ABI}. If your
66# package installs ABI-specific headers, just add 'prep_ml_includes' to the
67# end of your src_install(). It takes a list of directories that include
68# files are installed in (default is /usr/include if none are passed).
69#
70# Example:
71# src_install() {
72# ...
73# prep_ml_includes /usr/qt/3/include
74# }
75
76# create_ml_includes <include dir> <symbol 1>:<dir 1> [<symbol 2>:<dir 2> ...]
77# If you need more control than prep_ml_includes can offer (like linux-headers
78# for the asm-* dirs, then use create_ml_includes. The firs argument is the
79# common dir. The remaining args are of the form <symbol>:<dir> where
80# <symbol> is what is put in the #ifdef for choosing that dir.
81#
82# Ideas for this code came from debian's sparc-linux headers package.
83#
84# Example:
85# create_ml_includes /usr/include/asm __sparc__:/usr/include/asm-sparc __sparc64__:/usr/include/asm-sparc64
86# create_ml_includes /usr/include/asm __i386__:/usr/include/asm-i386 __x86_64__:/usr/include/asm-x86_64
87
88# get_libname [version]
89# returns libname with proper suffix {.so,.dylib} and optionally supplied version
90# for ELF/MACH-O shared objects
91#
92# Example:
93# get_libname libfoo ${PV}
94# Returns: libfoo.so.${PV} (ELF) || libfoo.${PV}.dylib (MACH)
