#
|
|
# This file 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
|
|
# * ARM, MIPS and PowerPC toolchains made available by
|
|
# Codesourcery. For the MIPS toolchain, the -muclibc variant isn't
|
|
# supported yet, only the default glibc-based variant is.
|
|
#
|
|
# The basic principle is the following
|
|
#
|
|
# 1. If the toolchain is not pre-installed, download and extract it
|
|
# in $(TOOLCHAIN_EXTERNAL_DIR).
|
|
#
|
|
# 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 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.

# 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[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[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' 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

|
# to the target filesystem.
