# Author: Jeremy Huddleston <eradicator@gentoo.org>
#
# This eclass is for all functions pertaining to handling multilib.
# configurations.
DESCRIPTION="Based on the ${ECLASS} eclass"
# has_multilib_profile:
# Return true if the current profile is a multilib profile and lists more than
# one abi in ${MULTILIB_ABIS}. You might want to use this like
# 'use multilib || has_multilib_profile' until all profiles utilizing the
# 'multilib' use flag are removed from portage
# is_final_abi:
# Return true if ${ABI} is the final abi to be installed (and thus we are
# on our last run through a src_* function.
# number_abis:
# echo the number of ABIs we will be installing for
# get_install_abis:
# Return a list of the ABIs we want to install for with
# the last one in the list being the default.
# get_all_abis:
# Return a list of the ABIs supported by this profile.
# the last one in the list being the default.
# get_all_libdirs:
# Returns a list of all the libdirs used by this profile. This includes
# those that might not be touched by the current ebuild and always includes
# "lib".
# get_libdir:
# Returns the libdir for the selected ABI. This is backwards compatible
# and simply calls get_abi_LIBDIR() on newer profiles. You should use this
# to determine where to install shared objects (ex: /usr/$(get_libdir))
# get_abi_var <VAR> [<ABI>]:
# returns the value of ${<VAR>_<ABI>} which should be set in make.defaults
#
# get_abi_CFLAGS:
# get_abi_CDEFINE:
# get_abi_LIBDIR:
# Aliases for 'get_abi_var CFLAGS', etc.
# get_ml_incdir [<include dir> [<ABI>]]
# include dir defaults to /usr/include
# ABI defaults to ${ABI} or ${DEFAULT_ABI}
#
# If a multilib include dir is associated with the passed include dir, then
# we return it, otherwise, we just echo back the include dir. This is
# neccessary when a built script greps header files rather than testing them
# via #include (like perl) to figure out features.
# prep_ml_includes:
# Some includes (include/asm, glibc, etc) are ABI dependent. In this case,
# We can install them in different locations for each ABI and create a common
# header which includes the right one based on CDEFINE_${ABI}. If your
# package installs ABI-specific headers, just add 'prep_ml_includes' to the
# end of your src_install(). It takes a list of directories that include
# files are installed in (default is /usr/include if none are passed).
#
# Example:
# src_install() {
# ...
# prep_ml_includes /usr/qt/3/include
# }
# create_ml_includes <include dir> <symbol 1>:<dir 1> [<symbol 2>:<dir 2> ...]
# If you need more control than prep_ml_includes can offer (like linux-headers
# for the asm-* dirs, then use create_ml_includes. The firs argument is the
# common dir. The remaining args are of the form <symbol>:<dir> where
# <symbol> is what is put in the #ifdef for choosing that dir.
#
# Ideas for this code came from debian's sparc-linux headers package.
#
# Example:
# create_ml_includes /usr/include/asm __sparc__:/usr/include/asm-sparc __sparc64__:/usr/include/asm-sparc64
# create_ml_includes /usr/include/asm __i386__:/usr/include/asm-i386 __x86_64__:/usr/include/asm-x86_64
# get_libname [version]
# returns libname with proper suffix {.so,.dylib} and optionally supplied version
# for ELF/MACH-O shared objects
#
# Example:
# get_libname libfoo ${PV}
# Returns: libfoo.so.${PV} (ELF) || libfoo.${PV}.dylib (MACH)

# to assume all libraries will end up in lib. Replace any (sane) instances
# where lib is named directly with $(get_libdir) if possible.
