14    
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 ${ABI} is the final abi to be installed (and thus we are
23     # on our last run through a src_* function.
24    
25     # number_abis:
26     # echo the number of ABIs we will be installing for
27    
28 eradicator 1.17 # get_install_abis:
29 eradicator 1.14 # Return a list of the ABIs we want to install for with
30     # the last one in the list being the default.
31    
32 eradicator 1.17 # get_all_abis:
33     # Return a list of the ABIs supported by this profile.
34     # the last one in the list being the default.
35    
36 eradicator 1.16 # get_all_libdirs:
37 eradicator 1.14 # Returns a list of all the libdirs used by this profile. This includes
38     # those that might not be touched by the current ebuild and always includes
39     # "lib".
40    
41     # get_libdir:
42     # Returns the libdir for the selected ABI. This is backwards compatible
43     # and simply calls get_abi_LIBDIR() on newer profiles. You should use this
44     # to determine where to install shared objects (ex: /usr/$(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

89 kito 1.31 # get_libname [version]
90 swegener 1.32 # returns libname with proper suffix {.so,.dylib} and optionally supplied version
91 kito 1.31 # for ELF/MACH-O shared objects
92     #
93     # Example:
94     # get_libname libfoo ${PV}
95     # Returns: libfoo.so.${PV} (ELF) || libfoo.${PV}.dylib (MACH)
