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. - -# -# Definitions of where the toolchain can be found -# - -TOOLCHAIN_EXTERNAL_PREFIX = $(call qstrip,$(BR2_TOOLCHAIN_EXTERNAL_PREFIX)) -TOOLCHAIN_EXTERNAL_DOWNLOAD_INSTALL_DIR = $(HOST_DIR)/opt/ext-toolchain - -ifeq ($(BR2_TOOLCHAIN_EXTERNAL_DOWNLOAD),y) -TOOLCHAIN_EXTERNAL_INSTALL_DIR = $(TOOLCHAIN_EXTERNAL_DOWNLOAD_INSTALL_DIR) -else -TOOLCHAIN_EXTERNAL_INSTALL_DIR = $(call qstrip,$(BR2_TOOLCHAIN_EXTERNAL_PATH)) -endif - -ifeq ($(TOOLCHAIN_EXTERNAL_INSTALL_DIR),) -ifneq ($(TOOLCHAIN_EXTERNAL_PREFIX),) -# if no path set, figure it out from path -TOOLCHAIN_EXTERNAL_BIN := $(shell dirname $(shell which $(TOOLCHAIN_EXTERNAL_PREFIX)-gcc)) -endif -else -ifeq ($(BR2_TOOLCHAIN_EXTERNAL_BLACKFIN_UCLINUX),y) -TOOLCHAIN_EXTERNAL_BIN := $(TOOLCHAIN_EXTERNAL_INSTALL_DIR)/$(TOOLCHAIN_EXTERNAL_PREFIX)/bin -else -TOOLCHAIN_EXTERNAL_BIN := $(TOOLCHAIN_EXTERNAL_INSTALL_DIR)/bin -endif -endif - -# If this is a buildroot toolchain, it already has a wrapper which we want to -# bypass.
