# This Makefile fragment declares toolchain related helper functions.
# The copy_toolchain_lib_root function copies a toolchain library and
# its symbolic links from the sysroot directory to the target
# directory. Note that this function is used both by the external
# toolchain logic, and the glibc package, so care must be taken when
# changing this function.
#
# Most toolchains (CodeSourcery ones) have their libraries either in
# /lib or /usr/lib relative to their ARCH_SYSROOT_DIR, so we search
# libraries in:
#
# $${ARCH_LIB_DIR}
# usr/$${ARCH_LIB_DIR}
#
# Buildroot toolchains, however, have basic libraries in /lib, and
# libstdc++/libgcc_s in /usr/<target-name>/lib(64), so we also need to
# search libraries in:
#
# usr/$(TOOLCHAIN_EXTERNAL_PREFIX)/$${ARCH_LIB_DIR}
#
# Linaro toolchains have most libraries in lib/<target-name>/, so we
# need to search libraries in:
#
# $${ARCH_LIB_DIR}/$(TOOLCHAIN_EXTERNAL_PREFIX)
#
# And recent Linaro toolchains have the GCC support libraries
# (libstdc++, libgcc_s, etc.) into a separate directory, outside of
# the sysroot, that we called the "SUPPORT_LIB_DIR", into which we
# need to search as well.
#
# Thanks to ARCH_LIB_DIR we also take into account toolchains that
# have the libraries in lib64 and usr/lib64.

# Copy the full external toolchain sysroot directory to the staging
# dir. The operation of this function is rendered a little bit
# complicated by the support for multilib toolchains.
#
# We start by copying etc, lib, sbin and usr from the sysroot of the
# selected architecture variant (as pointed by ARCH_SYSROOT_DIR). This
# allows to import into the staging directory the C library and
# companion libraries for the correct architecture variant. We
# explictly only copy etc, lib, sbin and usr since other directories
# might exist for other architecture variants (on Codesourcery
# toolchain, the sysroot for the default architecture variant contains
# the armv4t and thumb2 subdirectories, which are the sysroot for the
# corresponding architecture variants), and we don't want to import
# them.
#
# Then, we need to support two types of multilib toolchains:
#
# - The toolchains that have nested sysroots: a main sysroot, and
# then additional sysroots available as subdirectories of the main
# one. This is for example used by Sourcery CodeBench toolchains.
#
# - The toolchains that have side-by-side sysroots. Each sysroot is a
# complete one, they simply leave one next to each other. This is
# for example used by MIPS Codescape toolchains.
#
# So, we first detect if the selected architecture variant is not the
# default one (i.e, if SYSROOT_DIR != ARCH_SYSROOT_DIR).
#
# If we are in the situation of a nested sysroot, we:
#
# * If needed, import the header files from the default architecture
# variant. Header files are typically shared between the sysroots
# for the different architecture variants. If we use the
# non-default one, header files were not copied by the previous
# step, so we copy them here from the sysroot of the default
# architecture variant.
#
# * Create a symbolic link that matches the name of the subdirectory
# for the architecture variant in the original sysroot. This is
# required as the compiler will by default look in
# sysroot_dir/arch_variant/ for libraries and headers, when the
# non-default architecture variant is used. Without this, the
# compiler fails to find libraries and headers.
#
# If we are in the situation of a side-by-side sysroot, we:
#
# * Create a symbolic link
#
# Finally, some toolchains (i.e Linaro binary toolchains) store
# support libraries (libstdc++, libgcc_s) outside of the sysroot, so
# we simply copy all the libraries from the "support lib directory"
# into our sysroot.
#
# Note that the 'locale' directories are not copied. They are huge
# (400+MB) in CodeSourcery toolchains, and they are not really useful.
#
# $1: main sysroot directory of the toolchain
# $2: arch specific sysroot directory of the toolchain
# $3: arch specific subdirectory in the sysroot

This option allows to customize the "vendor" part of the
toolchain tuple, where the toolchain tuple has the form
<arch>-<vendor>-<os>-<libc>. The default value, "buildroot",
is fine for most cases, except in very specific situations
where gcc might make different decisions based on the vendor
part of the tuple. The value "unknown" is not allowed, as the
cross-compiling toolchain might then be confused with the
native toolchain when the target and host architecture are
identical. The value can not be empty either.
If you're not sure, just leave the default "buildroot" value.

help
Whitespace seperated list of locales to allow on target.
Locales not listed here will be removed from the target.
See 'locale -a' on your host for a list of locales available
on your build host, or have a look in /usr/share/locale in
the target file system for available locales.
Notice that listing a locale here doesn't guarantee that it
will be available on the target - That purely depends on the
support for that locale in the selected packages.

out the .so extension. Eg.:
IBM850 ISO8859-15 UNICODE
Note: the full set of gconv libs are ~8MiB (on ARM).

################################################################################
#
# This package implements the support for external toolchains, i.e
# toolchains that are available pre-built, ready to use. Such toolchain
# may either be readily available on the Web (Linaro, Sourcery
# CodeBench, from processor vendors) or may be built with tools like
# Crosstool-NG or Buildroot itself. So far, we have tested this
# with:
#
# * Toolchains generated by Crosstool-NG
# * Toolchains generated by Buildroot
# * Toolchains provided by Linaro for the ARM and AArch64
# architectures
# * Sourcery CodeBench toolchains (from Mentor Graphics) for the ARM,
# MIPS, PowerPC, x86, x86_64 and NIOS 2 architectures. For the MIPS
# toolchain, the -muclibc variant isn't supported yet, only the
# default glibc-based variant is.
# * Analog Devices toolchains for the Blackfin architecture
# * Xilinx toolchains for the Microblaze architecture
# * Synopsys DesignWare toolchains for ARC cores
#
# The basic principle is the following
#
# 1. If the toolchain is not pre-installed, download and extract it
# in $(TOOLCHAIN_EXTERNAL_INSTALL_DIR). Otherwise,
# $(TOOLCHAIN_EXTERNAL_INSTALL_DIR) points to were the toolchain has
# already been installed by the user.
#
# 2. For all external toolchains, perform some checks on the
# conformity between the toolchain configuration described in the
# Buildroot menuconfig system, and the real configuration of the
# external toolchain. This is for example important to make sure that
# the Buildroot configuration system knows whether the toolchain
# supports RPC, IPv6, locales, large files, etc. Unfortunately, these
# things cannot be detected automatically, since the value of these
# options (such as BR2_TOOLCHAIN_HAS_NATIVE_RPC) are needed at
# configuration time because these options are used as dependencies
# for other options. And at configuration time, we are not able to
# retrieve the external toolchain configuration.
#
# 3. Copy the libraries needed at runtime to the target directory,
# $(TARGET_DIR). Obviously, things such as the C library, the dynamic
# loader and a few other utility libraries are needed if dynamic
# applications are to be executed on the target system.
#
# 4. Copy the libraries and headers to the staging directory. This
# will allow all further calls to gcc to be made using --sysroot
# $(STAGING_DIR), which greatly simplifies the compilation of the
# packages when using external toolchains. So in the end, only the
# cross-compiler binaries remains external, all libraries and headers
# are imported into the Buildroot tree.
#
# 5. Build a toolchain wrapper which executes the external toolchain
# with a number of arguments (sysroot/march/mtune/..) hardcoded,
# so we're sure the correct configuration is always used and the
# toolchain behaves similar to an internal toolchain.
# This toolchain wrapper and symlinks are installed into
# $(HOST_DIR)/usr/bin like for the internal toolchains, and the rest
# of Buildroot is handled identical for the 2 toolchain types.

# Details about sysroot directory selection.
#
# To find the sysroot directory, we use the trick of looking for the
# 'libc.a' file with the -print-file-name gcc option, and then
# mangling the path to find the base directory of the sysroot.
#
# Note that we do not use the -print-sysroot option, because it is
# only available since gcc 4.4.x, and we only recently dropped support
# for 4.2.x and 4.3.x.
#
# When doing this, we don't pass any option to gcc that could select a
# multilib variant (such as -march) as we want the "main" sysroot,
# which contains all variants of the C library in the case of multilib
# toolchains. We use the TARGET_CC_NO_SYSROOT variable, which is the
# path of the cross-compiler, without the --sysroot=$(STAGING_DIR),
# since what we want to find is the location of the original toolchain
# sysroot. This "main" sysroot directory is stored in SYSROOT_DIR.
#
# Then, multilib toolchains are a little bit more complicated, since
# they in fact have multiple sysroots, one for each variant supported
# by the toolchain. So we need to find the particular sysroot we're
# interested in.
#
# To do so, we ask the compiler where its sysroot is by passing all
# flags (including -march and al.), except the --sysroot flag since we
# want to the compiler to tell us where its original sysroot
# is. ARCH_SUBDIR will contain the subdirectory, in the main
# SYSROOT_DIR, that corresponds to the selected architecture
# variant. ARCH_SYSROOT_DIR will contain the full path to this
# location.
#
# One might wonder why we don't just bother with ARCH_SYSROOT_DIR. The
# fact is that in multilib toolchains, the header files are often only
# present in the main sysroot, and only the libraries are available in
# each variant-specific sysroot directory.

# Ex: /x-tools/mips-2011.03/mips-linux-gnu/libc/usr/lib/libc.a

# usr/lib[32|64]/libc.a part of the path.
# Ex: /x-tools/mips-2011.03/mips-linux-gnu/libc/
#
# ARCH_LIBC_A_LOCATION: location of the libc.a file in the selected
# multilib variant (taking into account the
# CFLAGS). Allows to find the sysroot of the
# selected multilib variant.
# Ex: /x-tools/mips-2011.03/mips-linux-gnu/libc/mips16/soft-float/el/usr/lib/libc.a
#
# ARCH_SYSROOT_DIR: the sysroot of the selected multilib variant,
# deduced from ARCH_LIBC_A_LOCATION by removing
# usr/lib[32|64]/libc.a at the end of the path.
# Ex: /x-tools/mips-2011.03/mips-linux-gnu/libc/mips16/soft-float/el/
#
# ARCH_LIB_DIR: 'lib', 'lib32' or 'lib64' depending on where libraries
# are stored. Deduced from ARCH_LIBC_A_LOCATION by
# looking at usr/lib??/libc.a.
# Ex: lib
#
# ARCH_SUBDIR: the relative location of the sysroot of the selected
# multilib variant compared to the main sysroot.
# Ex: mips16/soft-float/el
#
# SUPPORT_LIB_DIR: some toolchains, such as recent Linaro toolchains,
# store GCC support libraries (libstdc++,
# libgcc_s, etc.) outside of the sysroot. In
# this case, SUPPORT_LIB_DIR is set to a
# non-empty value, and points to the directory
# where these support libraries are
# available. Those libraries will be copied to
