14
15 # has_multilib_profile:
16 # Return true if the current profile is a multilib profile and lists more than
17 # one abi in ${MULTILIB_ABIS}. You might want to use this like
18 # 'use multilib || has_multilib_profile' until all profiles utilizing the
19 # 'multilib' use flag are removed from portage
20
21 # is_final_abi:
22 # Return true if ${ABI} is the final abi to be installed (and thus we are
23 # on our last run through a src_* function.
24
25 # number_abis:
26 # echo the number of ABIs we will be installing for
27
28 # get_install_abis:
29 # Return a list of the ABIs we want to install for with
30 # the last one in the list being the default.
31
32 # get_all_abis:
33 # Return a list of the ABIs supported by this profile.
34 # the last one in the list being the default.
35
36 # get_all_libdirs:
37 # Returns a list of all the libdirs used by this profile. This includes
38 # those that might not be touched by the current ebuild and always includes
39 # "lib".
40
41 # get_libdir:
42 # Returns the libdir for the selected ABI. This is backwards compatible
43 # and simply calls get_abi_LIBDIR() on newer profiles. You should use this
44 # to determine where to install shared objects (ex: /usr/$(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
