| 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 |
|
|

| 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 | |

|

| 48 | # get_abi_LIBDIR: |

|
|
| 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) |
