11 DESCRIPTION="Based on the ${ECLASS} eclass"
12
13 # has_multilib_profile:
14 # Return true if the current profile is a multilib profile and lists more than
15 # one abi in ${MULTILIB_ABIS}. You might want to use this like
16 # 'use multilib || has_multilib_profile' until all profiles utilizing the
17 # 'multilib' use flag are removed from portage
18
19 # is_final_abi:
20 # Return true if ${ABI} is the final abi to be installed (and thus we are
21 # on our last run through a src_* function.
22
23 # number_abis:
24 # echo the number of ABIs we will be installing for
25
26 # get_install_abis:
27 # Return a list of the ABIs we want to install for with
28 # the last one in the list being the default.
29
30 # get_all_abis:
31 # Return a list of the ABIs supported by this profile.
32 # the last one in the list being the default.
33
34 # get_all_libdirs:
35 # Returns a list of all the libdirs used by this profile. This includes
36 # those that might not be touched by the current ebuild and always includes
37 # "lib".
38
39 # get_libdir:
40 # Returns the libdir for the selected ABI. This is backwards compatible
41 # and simply calls get_abi_LIBDIR() on newer profiles. You should use this
42 # to determine where to install shared objects (ex: /usr/$(get_libdir))
43
44 # get_abi_var <VAR> [<ABI>]:
45 # returns the value of ${<VAR>_<ABI>} which should be set in make.defaults
46 #
47 # get_abi_CFLAGS:
48 # get_abi_CDEFINE:
49 # get_abi_LIBDIR:
50 # Aliases for 'get_abi_var CFLAGS', etc.
51
52 # get_ml_incdir [<include dir> [<ABI>]]
53 # include dir defaults to /usr/include
54 # ABI defaults to ${ABI} or ${DEFAULT_ABI}
55 #
56 # If a multilib include dir is associated with the passed include dir, then
57 # we return it, otherwise, we just echo back the include dir. This is
58 # neccessary when a built script greps header files rather than testing them
59 # via #include (like perl) to figure out features.
60
61 # prep_ml_includes:
62 # Some includes (include/asm, glibc, etc) are ABI dependent. In this case,
63 # We can install them in different locations for each ABI and create a common
64 # header which includes the right one based on CDEFINE_${ABI}. If your
65 # package installs ABI-specific headers, just add 'prep_ml_includes' to the
66 # end of your src_install(). It takes a list of directories that include
67 # files are installed in (default is /usr/include if none are passed).
68 #
69 # Example:
70 # src_install() {
71 # ...
72 # prep_ml_includes /usr/qt/3/include
73 # }
74
75 # create_ml_includes <include dir> <symbol 1>:<dir 1> [<symbol 2>:<dir 2> ...]
76 # If you need more control than prep_ml_includes can offer (like linux-headers
77 # for the asm-* dirs, then use create_ml_includes. The firs argument is the
78 # common dir. The remaining args are of the form <symbol>:<dir> where
79 # <symbol> is what is put in the #ifdef for choosing that dir.
80 #
81 # Ideas for this code came from debian's sparc-linux headers package.
82 #
83 # Example:
84 # create_ml_includes /usr/include/asm __sparc__:/usr/include/asm-sparc __sparc64__:/usr/include/asm-sparc64
85 # create_ml_includes /usr/include/asm __i386__:/usr/include/asm-i386 __x86_64__:/usr/include/asm-x86_64
86
87 # get_libname [version]
88 # returns libname with proper suffix {.so,.dylib} and optionally supplied version
89 # for ELF/MACH-O shared objects
90 #
91 # Example:
92 # get_libname libfoo ${PV}
93 # Returns: libfoo.so.${PV} (ELF) || libfoo.${PV}.dylib (MACH)
