12# has_multilib_profile:
13# Return true if the current profile is a multilib profile and lists more than
14# one abi in ${MULTILIB_ABIS}. You might want to use this like
15# 'use multilib || has_multilib_profile' until all profiles utilizing the
16# 'multilib' use flag are removed from portage
17
18# is_final_abi:
19# Return true if ${ABI} is the final abi to be installed (and thus we are
20# on our last run through a src_* function.
21
22# number_abis:
23# echo the number of ABIs we will be installing for
24
25# get_install_abis:
26# Return a list of the ABIs we want to install for with
27# the last one in the list being the default.
28
29# get_all_abis:
30# Return a list of the ABIs supported by this profile.
31# the last one in the list being the default.
32
33# get_all_libdirs:
34# Returns a list of all the libdirs used by this profile. This includes
35# those that might not be touched by the current ebuild and always includes
36# "lib".
37
38# get_libdir:
39# Returns the libdir for the selected ABI. This is backwards compatible
40# and simply calls get_abi_LIBDIR() on newer profiles. You should use this
41# to determine where to install shared objects (ex: /usr/$(get_libdir))
42
43# get_abi_var <VAR> [<ABI>]:
44# returns the value of ${<VAR>_<ABI>} which should be set in make.defaults
45#
46# get_abi_CFLAGS:
47# get_abi_CDEFINE:
48# get_abi_LIBDIR:
49# Aliases for 'get_abi_var CFLAGS', etc.
50
51# get_ml_incdir [<include dir> [<ABI>]]
52# include dir defaults to /usr/include
53# ABI defaults to ${ABI} or ${DEFAULT_ABI}
54#
55# If a multilib include dir is associated with the passed include dir, then
56# we return it, otherwise, we just echo back the include dir. This is
57# neccessary when a built script greps header files rather than testing them
58# via #include (like perl) to figure out features.
59
60# prep_ml_includes:
61# Some includes (include/asm, glibc, etc) are ABI dependent. In this case,
62# We can install them in different locations for each ABI and create a common
63# header which includes the right one based on CDEFINE_${ABI}. If your
64# package installs ABI-specific headers, just add 'prep_ml_includes' to the
65# end of your src_install(). It takes a list of directories that include
66# files are installed in (default is /usr/include if none are passed).
67#
68# Example:
69# src_install() {
70# ...
71# prep_ml_includes /usr/qt/3/include
72# }
73
74# create_ml_includes <include dir> <symbol 1>:<dir 1> [<symbol 2>:<dir 2> ...]
75# If you need more control than prep_ml_includes can offer (like linux-headers
76# for the asm-* dirs, then use create_ml_includes. The firs argument is the
77# common dir. The remaining args are of the form <symbol>:<dir> where
78# <symbol> is what is put in the #ifdef for choosing that dir.
79#
80# Ideas for this code came from debian's sparc-linux headers package.
81#
82# Example:
83# create_ml_includes /usr/include/asm __sparc__:/usr/include/asm-sparc __sparc64__:/usr/include/asm-sparc64
84# create_ml_includes /usr/include/asm __i386__:/usr/include/asm-i386 __x86_64__:/usr/include/asm-x86_64
85
86# get_libname [version]
87# returns libname with proper suffix {.so,.dylib} and optionally supplied version
88# for ELF/MACH-O shared objects
89#
90# Example:
91# get_libname libfoo ${PV}
92# Returns: libfoo.so.${PV} (ELF) || libfoo.${PV}.dylib (MACH)
