17# one abi in ${MULTILIB_ABIS}. You might want to use this like 31# one abi in ${MULTILIB_ABIS}. When has_multilib_profile returns true, that

19# 'multilib' use flag are removed from portage 33# a package only for multilib or not multilib.

23# on our last run through a src_* function.

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