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