14 eradicator 1.14 # has_multilib_profile:
15 eradicator 1.15 # Return true if the current profile is a multilib profile and lists more than
16     # one abi in ${MULTILIB_ABIS}. You might want to use this like
17     # 'use multilib || has_multilib_profile' until all profiles utilizing the
18     # 'multilib' use flag are removed from portage
19 eradicator 1.14
20     # is_final_abi:
21     # Return true if ${ABI} is the final abi to be installed (and thus we are
22     # on our last run through a src_* function.
23    
24     # number_abis:
25     # echo the number of ABIs we will be installing for
26    
27 eradicator 1.17 # get_install_abis:
28 eradicator 1.14 # Return a list of the ABIs we want to install for with
29     # the last one in the list being the default.
30    
31 eradicator 1.17 # get_all_abis:
32     # Return a list of the ABIs supported by this profile.
33     # the last one in the list being the default.
34    
35 eradicator 1.16 # get_all_libdirs:
36 eradicator 1.14 # Returns a list of all the libdirs used by this profile. This includes
37     # those that might not be touched by the current ebuild and always includes
38     # "lib".
39    
40     # get_libdir:
41     # Returns the libdir for the selected ABI. This is backwards compatible
42     # and simply calls get_abi_LIBDIR() on newer profiles. You should use this
43     # to determine where to install shared objects (ex: /usr/$(get_libdir))
44    
45     # get_abi_var <VAR> [<ABI>]:
46     # returns the value of ${<VAR>_<ABI>} which should be set in make.defaults
47     #
48     # get_abi_CFLAGS:
49     # get_abi_CDEFINE:
50     # get_abi_LIBDIR:
51     # Aliases for 'get_abi_var CFLAGS', etc.
52    
53     # get_ml_incdir [<include dir> [<ABI>]]
54     # include dir defaults to /usr/include
55     # ABI defaults to ${ABI} or ${DEFAULT_ABI}
56     #
57     # If a multilib include dir is associated with the passed include dir, then
58     # we return it, otherwise, we just echo back the include dir. This is
59     # neccessary when a built script greps header files rather than testing them
60     # via #include (like perl) to figure out features.
61    
62     # prep_ml_includes:
63     # Some includes (include/asm, glibc, etc) are ABI dependent. In this case,
64     # We can install them in different locations for each ABI and create a common
65     # header which includes the right one based on CDEFINE_${ABI}. If your
66     # package installs ABI-specific headers, just add 'prep_ml_includes' to the
67     # end of your src_install(). It takes a list of directories that include
68     # files are installed in (default is /usr/include if none are passed).
69     #
70     # Example:
71     # src_install() {
72     # ...
73     # prep_ml_includes /usr/qt/3/include
74     # }
75    
76     # create_ml_includes <include dir> <symbol 1>:<dir 1> [<symbol 2>:<dir 2> ...]
77     # If you need more control than prep_ml_includes can offer (like linux-headers
78     # for the asm-* dirs, then use create_ml_includes. The firs argument is the
79     # common dir. The remaining args are of the form <symbol>:<dir> where
80     # <symbol> is what is put in the #ifdef for choosing that dir.
81     #
82     # Ideas for this code came from debian's sparc-linux headers package.
83     #
84     # Example:
85     # create_ml_includes /usr/include/asm __sparc__:/usr/include/asm-sparc __sparc64__:/usr/include/asm-sparc64
86     # create_ml_includes /usr/include/asm __i386__:/usr/include/asm-i386 __x86_64__:/usr/include/asm-x86_64
