15 eradicator 1.14 # has_multilib_profile:
16 eradicator 1.15 # 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 eradicator 1.14
21     # is_final_abi:
22     # Return true if ${ABI} is the final abi to be installed (and thus we are
23     # on our last run through a src_* function.
24    
25     # number_abis:
26     # echo the number of ABIs we will be installing for
27    
28     # get_abi_order:
29     # Return a list of the ABIs we want to install for with
30     # the last one in the list being the default.
31    
32     # get_all_libdir:
33     # Returns a list of all the libdirs used by this profile. This includes
34     # those that might not be touched by the current ebuild and always includes
35     # "lib".
36    
37     # get_libdir:
38     # Returns the libdir for the selected ABI. This is backwards compatible
39     # and simply calls get_abi_LIBDIR() on newer profiles. You should use this
40     # to determine where to install shared objects (ex: /usr/$(get_libdir))
41    
42     # get_abi_var <VAR> [<ABI>]:
43     # returns the value of ${<VAR>_<ABI>} which should be set in make.defaults
44     #
45     # get_abi_CFLAGS:
46     # get_abi_CDEFINE:
47     # get_abi_LIBDIR:
48     # Aliases for 'get_abi_var CFLAGS', etc.
49    
50     # get_ml_incdir [<include dir> [<ABI>]]
51     # include dir defaults to /usr/include
52     # ABI defaults to ${ABI} or ${DEFAULT_ABI}
53     #
54     # If a multilib include dir is associated with the passed include dir, then
55     # we return it, otherwise, we just echo back the include dir. This is
56     # neccessary when a built script greps header files rather than testing them
57     # via #include (like perl) to figure out features.
58    
59     # prep_ml_includes:
60     # Some includes (include/asm, glibc, etc) are ABI dependent. In this case,
61     # We can install them in different locations for each ABI and create a common
62     # header which includes the right one based on CDEFINE_${ABI}. If your
63     # package installs ABI-specific headers, just add 'prep_ml_includes' to the
64     # end of your src_install(). It takes a list of directories that include
65     # files are installed in (default is /usr/include if none are passed).
66     #
67     # Example:
68     # src_install() {
69     # ...
70     # prep_ml_includes /usr/qt/3/include
71     # }
72    
73     # create_ml_includes <include dir> <symbol 1>:<dir 1> [<symbol 2>:<dir 2> ...]
74     # If you need more control than prep_ml_includes can offer (like linux-headers
75     # for the asm-* dirs, then use create_ml_includes. The firs argument is the
76     # common dir. The remaining args are of the form <symbol>:<dir> where
77     # <symbol> is what is put in the #ifdef for choosing that dir.
78     #
79     # Ideas for this code came from debian's sparc-linux headers package.
80     #
81     # Example:
82     # create_ml_includes /usr/include/asm __sparc__:/usr/include/asm-sparc __sparc64__:/usr/include/asm-sparc64
83     # create_ml_includes /usr/include/asm __i386__:/usr/include/asm-i386 __x86_64__:/usr/include/asm-x86_64
