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