# This file implements the support for external toolchains, i.e
# toolchains that have not been produced by Buildroot itself and that
-# are already available on the system on which Buildroot runs. So far,
-# we have tested this with:
+# 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
#
# The basic principle is the following
#
-# 1. 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_INET_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.
+# 1. a. For toolchains downloaded from the Web, Buildroot already
+# knows their configuration, so it just downloads them and extract
+# them in $(TOOLCHAIN_EXTERNAL_DIR).
+#
+# 1. b. For pre-installed 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_INET_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.
#
# 2. Copy the libraries needed at runtime to the target directory,
# $(TARGET_DIR). Obviously, things such as the C library, the dynamic

-# SYSROOT_DIR selection. We first try the -print-sysroot option,
-# available in gcc 4.4.x and in some Codesourcery toolchains. If this
-# option is not available, we fallback to the value of --with-sysroot
-# as visible in CROSS-gcc -v. We don't pass any option to gcc that
-# could select a multilib variant as we want the "main" sysroot, which
-# contains all variants of the C library in the case of multilib
-# toolchains.
+# Details about sysroot directory selection.
+#
+# To find the sysroot directory:
+#
+# * We first try the -print-sysroot option, available in gcc 4.4.x
+# and in some Codesourcery toolchains.
+#
+# * If this option is not available, we fallback to the value of
+# --with-sysroot as visible in CROSS-gcc -v.
+#
+# When doing those tests, 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.
