#
################################################################################
#
# This package implements the support for external toolchains, i.e
# toolchains that have not been produced by Buildroot itself and that
# Buildroot can download from the Web or that are already available on
# the system on which Buildroot runs. 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
#
# 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 still support 4.2.x (for
# AVR32) 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.

# to $(STAGING_DIR).
#

#
# LIBC_A_LOCATION: location of the libc.a file in the default
# multilib variant (allows to find the main
# sysroot directory)
# Ex: /x-tools/mips-2011.03/mips-linux-gnu/libc/usr/lib/libc.a
#
# SYSROOT_DIR: the main sysroot directory, deduced from
# LIBC_A_LOCATION by removing the
# 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
# our sysroot, and the directory will also be
# considered when searching libraries for copy
