Subject: [Buildroot] [PATCH 30/30] toolchain-external: introduce and use external toolchain infra
Date: Sun, 23 Oct 2016 22:48:31 +0200 [thread overview]
Message-ID: <1477255711-28603-31-git-send-email-romain.naour@gmail.com> (raw)
In-Reply-To: <1477255711-28603-1-git-send-email-romain.naour@gmail.com>
This fairly large commit is needed to switch in one atomic change from
the old single package based external toolchain handling, to a
mechanism based on a common external toolchain package infrastructure
and separate packages for each toolchain family. The purpose is to
clearly separate the common external toolchain logic from the
toolchain-specific details and generally make the external toolchain
code hopefully easier to maintain.
To achieve this, this commit:
- Introduce in pkg-toolchain-external.mk the
'toolchain-external-package' macro, which is the core of the
external toolchain package infrastructure. Like any other package
infrastructure, it defines a number of variables and provides a
behavior for the configure, build and install steps.
- Turn the toolchain-external.mk file in a simple virtual package,
which automatically depends on the selected external
toolchain. Like any other virtual package, the Kconfig variable
BR2_PACKAGE_PROVIDES_TOOLCHAIN_EXTERNAL indicates which package is
providing the currently selected toolchain.
- Removes all the toolchain-specific definitions from
toolchain/toolchain-external/Config.in and remove
toolchain/toolchain-external/pkg-toolchain-external-download.mk
as well as the hash file, and instead use the per-toolchain packages
in the subdirectories toolchain/toolchain-external/*/.
- Wine: Use $(TOOLCHAIN_EXTERNAL_PREFIX) instead of
$(BR2_TOOLCHAIN_EXTERNAL_PREFIX) which was removed.
- Remove the old toolchain-external.hash file. The hash is now
provided by the toolchain package.
Notes:
- The hack for setting TOOLCHAIN_EXTERNAL_BIN for the ADI bfin
toolchain is no longer needed.

+# 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 $(HOST_DIR)/opt/ext-toolchain. Otherwise, we use the toolchain
+# from the location where it has 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, 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.

################################################################################
-#
-# 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
-# $(HOST_DIR)/usr/bin like for the internal toolchains, and the rest
-# of Buildroot is handled identical for the 2 toolchain types.
-
-# Details about sysroot directory selection.
-#
-# To find the sysroot directory, we use the trick of looking for the
-# 'libc.a' file with the -print-file-name gcc option, and then
-# mangling the path to find the base directory of the sysroot.
-#
-# Note that we do not use the -print-sysroot option, because it is
-# only available since gcc 4.4.x, and we only recently dropped support
-# for 4.2.x and 4.3.x.
-#
-# When doing this, we don't pass any option to gcc that could select a
-# multilib variant (such as -march) as we want the "main" sysroot,
-# which contains all variants of the C library in the case of multilib
-# toolchains. We use the TARGET_CC_NO_SYSROOT variable, which is the
-# path of the cross-compiler, without the --sysroot=$(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
-# each variant-specific sysroot directory.
