34     # "lib".
35    
36     # get_libdir:
37     # Returns the libdir for the selected ABI. This is backwards compatible
38     # and simply calls get_abi_LIBDIR() on newer profiles. You should use this
39     # to determine where to install shared objects (ex: /usr/$(get_libdir))
40    
41     # get_abi_var <VAR> [<ABI>]:
42     # returns the value of ${<VAR>_<ABI>} which should be set in make.defaults
43     #
44     # get_abi_CFLAGS:
45     # get_abi_CDEFINE:
46     # get_abi_LIBDIR:
47     # Aliases for 'get_abi_var CFLAGS', etc.
48    
49     # get_ml_incdir [<include dir> [<ABI>]]
50     # include dir defaults to /usr/include
51     # ABI defaults to ${ABI} or ${DEFAULT_ABI}
52     #
53     # If a multilib include dir is associated with the passed include dir, then
54     # we return it, otherwise, we just echo back the include dir. This is
55     # neccessary when a built script greps header files rather than testing them
56     # via #include (like perl) to figure out features.
57    
58     # prep_ml_includes:
59     # Some includes (include/asm, glibc, etc) are ABI dependent. In this case,
60     # We can install them in different locations for each ABI and create a common
61     # header which includes the right one based on CDEFINE_${ABI}. If your
62     # package installs ABI-specific headers, just add 'prep_ml_includes' to the
63     # end of your src_install(). It takes a list of directories that include
64     # files are installed in (default is /usr/include if none are passed).
65     #
66     # Example:
67     # src_install() {
68     # ...
69     # prep_ml_includes /usr/qt/3/include
70     # }
71    
72     # create_ml_includes <include dir> <symbol 1>:<dir 1> [<symbol 2>:<dir 2> ...]
73     # If you need more control than prep_ml_includes can offer (like linux-headers
74     # for the asm-* dirs, then use create_ml_includes. The firs argument is the
75     # common dir. The remaining args are of the form <symbol>:<dir> where
76     # <symbol> is what is put in the #ifdef for choosing that dir.
77     #
78     # Ideas for this code came from debian's sparc-linux headers package.
79     #
80     # Example:
81     # create_ml_includes /usr/include/asm __sparc__:/usr/include/asm-sparc __sparc64__:/usr/include/asm-sparc64
82     # create_ml_includes /usr/include/asm __i386__:/usr/include/asm-i386 __x86_64__:/usr/include/asm-x86_64

441 eradicator 1.2 # If you need more control than prep_ml_includes can offer (like linux-headers
442     # for the asm-* dirs, then use create_ml_includes. The firs argument is the
443     # common dir. The remaining args are of the form <symbol>:<dir> where
444     # <symbol> is what is put in the #ifdef for choosing that dir.
445     #
446     # Ideas for this code came from debian's sparc-linux headers package.
447     #
448     # Example:
449 vapier 1.65 # create_ml_includes /usr/include/asm __sparc__:/usr/include/asm-sparc __sparc64__:/usr/include/asm-sparc64
450     # create_ml_includes /usr/include/asm __i386__:/usr/include/asm-i386 __x86_64__:/usr/include/asm-x86_64
