32 | |
|

33 | # get_all_libdirs: |
|
|
34 | # Returns a list of all the libdirs used by this profile. This includes |
|
|
35 | # those that might not be touched by the current ebuild and always includes |
|
|
36 | # "lib". |

|
38 | # get_libdir: |
|
|
39 | # Returns the libdir for the selected ABI. This is backwards compatible |
|
|
40 | # and simply calls get_abi_LIBDIR() on newer profiles. You should use this |
|
|
41 | # to determine where to install shared objects (ex: /usr/$(get_libdir)) |
|
|
42 | |
|
|
43 | # get_abi_var <VAR> [<ABI>]: |
|
|
44 | # returns the value of ${<VAR>_<ABI>} which should be set in make.defaults |

46 | # get_abi_CFLAGS: |
|
|
47 | # get_abi_CDEFINE: |
|
|
48 | # get_abi_LIBDIR: |
|
|
49 | # Aliases for 'get_abi_var CFLAGS', etc. |
|
|
50 | |
|
|
51 | # get_ml_incdir [<include dir> [<ABI>]] |
|
|
52 | # include dir defaults to /usr/include |
|
|
53 | # ABI defaults to ${ABI} or ${DEFAULT_ABI} |
|
|
54 | # |
|
|
55 | # If a multilib include dir is associated with the passed include dir, then |
|
|
56 | # we return it, otherwise, we just echo back the include dir. This is |
|
|
57 | # neccessary when a built script greps header files rather than testing them |
|
|
58 | # via #include (like perl) to figure out features. |
|
|
59 | |
|
|
60 | # prep_ml_includes: |
|
|
61 | # Some includes (include/asm, glibc, etc) are ABI dependent. In this case, |
|
|
62 | # We can install them in different locations for each ABI and create a common |
|
|
63 | # header which includes the right one based on CDEFINE_${ABI}. If your |
|
|
64 | # package installs ABI-specific headers, just add 'prep_ml_includes' to the |
|
|
65 | # end of your src_install(). It takes a list of directories that include |
|
|
66 | # files are installed in (default is /usr/include if none are passed). |
|
|
67 | # |
|
|
68 | # Example: |
|
|
69 | # src_install() { |
|
|
70 | # ... |
|
|
71 | # prep_ml_includes /usr/qt/3/include |
|
|
72 | # } |
|
|
73 | |
|
|
74 | # create_ml_includes <include dir> <symbol 1>:<dir 1> [<symbol 2>:<dir 2> ...] |
|
|
75 | # If you need more control than prep_ml_includes can offer (like linux-headers |
|
|
76 | # for the asm-* dirs, then use create_ml_includes. The firs argument is the |
|
|
77 | # common dir. The remaining args are of the form <symbol>:<dir> where |
|
|
78 | # <symbol> is what is put in the #ifdef for choosing that dir. |
|
|
79 | # |
|
|
80 | # Ideas for this code came from debian's sparc-linux headers package. |
|
|
81 | # |
|
|
82 | # Example: |
|
|
83 | # create_ml_includes /usr/include/asm __sparc__:/usr/include/asm-sparc __sparc64__:/usr/include/asm-sparc64 |
|
|
84 | # create_ml_includes /usr/include/asm __i386__:/usr/include/asm-i386 __x86_64__:/usr/include/asm-x86_64 |
|
|
85 | |
|
|
86 | # get_libname [version] |
|
|
87 | # returns libname with proper suffix {.so,.dylib} and optionally supplied version |
|
|
88 | # for ELF/MACH-O shared objects |
|
|
89 | # |
|
|
90 | # Example: |
|
|
91 | # get_libname libfoo ${PV} |
|
|
92 | # Returns: libfoo.so.${PV} (ELF) || libfoo.${PV}.dylib (MACH) |
