12 DESCRIPTION="Based on the ${ECLASS} eclass"
13
14 # has_multilib_profile:
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
20 # is_final_abi:
21 # Return true if ${ABI} is the final abi to be installed (and thus we are
22 # on our last run through a src_* function.
23
24 # number_abis:
25 # echo the number of ABIs we will be installing for
26
27 # get_install_abis:
28 # Return a list of the ABIs we want to install for with
29 # the last one in the list being the default.
30
31 # get_all_abis:
32 # Return a list of the ABIs supported by this profile.
33 # the last one in the list being the default.
34
35 # get_all_libdirs:
36 # Returns a list of all the libdirs used by this profile. This includes
37 # those that might not be touched by the current ebuild and always includes
38 # "lib".
39
40 # get_libdir:
41 # Returns the libdir for the selected ABI. This is backwards compatible
42 # and simply calls get_abi_LIBDIR() on newer profiles. You should use this
43 # to determine where to install shared objects (ex: /usr/$(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
