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