toolchain-external: move parts to pkg-toolchain-external.mk
pkg-toolchain-external.mk will be used later to define the toolchain-external-package infra. Most of the variable and macro definitions are shared with the legacy generic-package based toolchain-external. Move these to pkg-toolchain-external.mk. pkg-toolchain-external.mk is included implicitly by the include toolchain/*/*.mk in the top-level Makefile. The order of inclusion is not defined, but that doesn't matter because none of the variables defined in pkg-toolchain-external.mk are used in conditions or in rules in toolchain-external.mk, only in recursively-expanded variables. No functional changes at all. The output of 'make -qp' hasn't changed.

# External toolchain package infrastructure
|
||||
#
|
||||
# This package infrastructure 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.

# Various utility functions used by the external toolchain package
|

# infrastructure. Those functions are mainly responsible for:
|
||||
#
|
||||
# - installation the toolchain libraries to $(TARGET_DIR)
|
||||
# - copying the toolchain sysroot to $(STAGING_DIR)
|
||||
# - installing a gdbinit file
|
||||
#
|
||||
# Details about sysroot directory selection.
|
||||
#
|
||||
# To find the sysroot directory, we use the trick of looking for the
|
||||
# 'libc.a' file with the -print-file-name gcc option, and then
|
||||
# mangling the path to find the base directory of the sysroot.
|
||||
#
|
||||
# Note that we do not use the -print-sysroot option, because it is
|
||||
# only available since gcc 4.4.x, and we only recently dropped support
|
||||
# for 4.2.x and 4.3.x.
|
||||
#
|
||||
# When doing this, we don't pass any option to gcc that could select a
|
||||
# multilib variant (such as -march) as we want the "main" sysroot,
|
||||
# which contains all variants of the C library in the case of multilib
|
||||
# toolchains. We use the TARGET_CC_NO_SYSROOT variable, which is the
|
||||
# path of the cross-compiler, without the --sysroot=$(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

################################################################################
|
||||
|
||||
#
|
||||
# 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.

# Various utility functions used by the external toolchain package

|

# - installation the toolchain libraries to $(TARGET_DIR)
|
||||
# - copying the toolchain sysroot to $(STAGING_DIR)
|
||||
# - installing a gdbinit file
|
||||
#
|
||||
# Details about sysroot directory selection.
|
||||
#
|
||||
# To find the sysroot directory, we use the trick of looking for the
|
||||
# 'libc.a' file with the -print-file-name gcc option, and then
|
||||
# mangling the path to find the base directory of the sysroot.
|
||||
#
|
||||
# Note that we do not use the -print-sysroot option, because it is
|
||||
# only available since gcc 4.4.x, and we only recently dropped support
|
||||
# for 4.2.x and 4.3.x.
|
||||
#
|
||||
# When doing this, we don't pass any option to gcc that could select a
|
||||
# multilib variant (such as -march) as we want the "main" sysroot,
|
||||
# which contains all variants of the C library in the case of multilib
|
||||
# toolchains. We use the TARGET_CC_NO_SYSROOT variable, which is the
|
||||
# path of the cross-compiler, without the --sysroot=$(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
