# This eclass is for all functions pertaining to handling multilib.
# configurations.

DESCRIPTION="Based on the ${ECLASS} eclass"

# has_multilib_profile:
# Return true if the current profile is a multilib profile and lists more than
# one abi in ${MULTILIB_ABIS}.  You might want to use this like
# 'use multilib || has_multilib_profile' until all profiles utilizing the
# 'multilib' use flag are removed from portage

# is_final_abi:
# Return true if ${ABI} is the final abi to be installed (and thus we are
# on our last run through a src_* function.

# number_abis:
# echo the number of ABIs we will be installing for

# get_install_abis:
# Return a list of the ABIs we want to install for with
# the last one in the list being the default.

# get_all_abis:
# Return a list of the ABIs supported by this profile.
# the last one in the list being the default.

# get_all_libdirs:
# Returns a list of all the libdirs used by this profile.  This includes
# those that might not be touched by the current ebuild and always includes
# "lib".

# get_libdir:
# Returns the libdir for the selected ABI.  This is backwards compatible
# and simply calls get_abi_LIBDIR() on newer profiles.  You should use this
# to determine where to install shared objects (ex: /usr/$(get_libdir))

# get_abi_var <VAR> [<ABI>]:
# returns the value of ${<VAR>_<ABI>} which should be set in make.defaults
#
# get_abi_CFLAGS:
# get_abi_CDEFINE:
# get_abi_LIBDIR:
# Aliases for 'get_abi_var CFLAGS', etc.

# get_ml_incdir [<include dir> [<ABI>]]
# include dir defaults to /usr/include
# ABI defaults to ${ABI} or ${DEFAULT_ABI}
#
# If a multilib include dir is associated with the passed include dir, then
# we return it, otherwise, we just echo back the include dir.  This is
# neccessary when a built script greps header files rather than testing them
# via #include (like perl) to figure out features.

# prep_ml_includes:
# Some includes (include/asm, glibc, etc) are ABI dependent.  In this case,
# We can install them in different locations for each ABI and create a common
# header which includes the right one based on CDEFINE_${ABI}.  If your
# package installs ABI-specific headers, just add 'prep_ml_includes' to the
# end of your src_install().  It takes a list of directories that include
# files are installed in (default is /usr/include if none are passed).
#
# Example:
# src_install() {
#    ...
#    prep_ml_includes /usr/qt/3/include
# }

# create_ml_includes <include dir> <symbol 1>:<dir 1> [<symbol 2>:<dir 2> ...]
# If you need more control than prep_ml_includes can offer (like linux-headers
# for the asm-* dirs, then use create_ml_includes.  The firs argument is the
# common dir.  The remaining args are of the form <symbol>:<dir> where
# <symbol> is what is put in the #ifdef for choosing that dir.
#
# Ideas for this code came from debian's sparc-linux headers package.
#
# Example:
# create_ml_includes /usr/include/asm __sparc__:/usr/include/asm-sparc __sparc64__:/usr/include/asm-sparc64
# create_ml_includes /usr/include/asm __i386__:/usr/include/asm-i386 __x86_64__:/usr/include/asm-x86_64

# get_libname [version]
# returns libname with proper suffix {.so,.dylib} and optionally supplied version
# for ELF/MACH-O shared objects
#
# Example:
# get_libname libfoo ${PV}
# Returns: libfoo.so.${PV} (ELF) || libfoo.${PV}.dylib (MACH)

10	DESCRIPTION="Based on the ${ECLASS} eclass"
11
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)
