# This Makefile fragment declares toolchain related helper functions.
# The copy_toolchain_lib_root function copies a toolchain library and
# its symbolic links from the sysroot directory to the target
# directory. Note that this function is used both by the external
# toolchain logic, and the glibc package, so care must be taken when
# changing this function.
#
# Most toolchains (CodeSourcery ones) have their libraries either in
# /lib or /usr/lib relative to their ARCH_SYSROOT_DIR, so we search
# libraries in:
#
# $${ARCH_LIB_DIR}
# usr/$${ARCH_LIB_DIR}
#
# Buildroot toolchains, however, have basic libraries in /lib, and
# libstdc++/libgcc_s in /usr/<target-name>/lib(64), so we also need to
# search libraries in:
#
# usr/$(TOOLCHAIN_EXTERNAL_PREFIX)/$${ARCH_LIB_DIR}
#
# Linaro toolchains have most libraries in lib/<target-name>/, so we
# need to search libraries in:
#
# $${ARCH_LIB_DIR}/$(TOOLCHAIN_EXTERNAL_PREFIX)
#
# And recent Linaro toolchains have the GCC support libraries
# (libstdc++, libgcc_s, etc.) into a separate directory, outside of
# the sysroot, that we called the "SUPPORT_LIB_DIR", into which we
# need to search as well.
#
# Thanks to ARCH_LIB_DIR we also take into account toolchains that
# have the libraries in lib64 and usr/lib64.
#
# Please be very careful to check the major toolchain sources:
# Buildroot, Crosstool-NG, CodeSourcery and Linaro before doing any
# modification on the below logic.
#
# $1: arch specific sysroot directory
# $2: support libraries directory (can be empty)
# $3: library directory ('lib' or 'lib64') from which libraries must be copied

# Copy the full external toolchain sysroot directory to the staging
# dir. The operation of this function is rendered a little bit
# complicated by the support for multilib toolchains.
#
# We start by copying etc, lib, sbin and usr from the sysroot of the
# selected architecture variant (as pointed by ARCH_SYSROOT_DIR). This
# allows to import into the staging directory the C library and
# companion libraries for the correct architecture variant. We
# explictly only copy etc, lib, sbin and usr since other directories
# might exist for other architecture variants (on Codesourcery
# toolchain, the sysroot for the default architecture variant contains
# the armv4t and thumb2 subdirectories, which are the sysroot for the
# corresponding architecture variants), and we don't want to import
# them.
#
# Then, if the selected architecture variant is not the default one
# (i.e, if SYSROOT_DIR != ARCH_SYSROOT_DIR), then we :
#
# * Import the header files from the default architecture
# variant. Header files are typically shared between the sysroots
# for the different architecture variants. If we use the
# non-default one, header files were not copied by the previous
# step, so we copy them here from the sysroot of the default
# architecture variant.
#
# * Create a symbolic link that matches the name of the subdirectory
# for the architecture variant in the original sysroot. This is
# required as the compiler will by default look in
# sysroot_dir/arch_variant/ for libraries and headers, when the
# non-default architecture variant is used. Without this, the
# compiler fails to find libraries and headers.
#
# Some toolchains (i.e Linaro binary toolchains) store support
# libraries (libstdc++, libgcc_s) outside of the sysroot, so we simply
# copy all the libraries from the "support lib directory" into our
# sysroot.
#
# Note that the 'locale' directories are not copied. They are huge
# (400+MB) in CodeSourcery toolchains, and they are not really useful.
#
# $1: main sysroot directory of the toolchain
# $2: arch specific sysroot directory of the toolchain
# $3: arch specific subdirectory in the sysroot

Improve external toolchain logic to support IA32 Sourcery CodeBench toolchain The IA32 Sourcery CodeBench toolchain has a relatively special structure, with the following multilib variants: * Intel Pentium 4, 32 bits, the multilib variant is in ./ relative to the main sysroot, with the libraries in the lib/ directory. * Intel Xeon Nocona, 64 bits, the multilib variant is in ./ relative to the main sysroot, with the libraries in the lib64/ directory. * Intel Atom 32 bits, the multilib variant is in atom/ relative to the main sysroot, with the libraries in the lib/ directory. * Intel Core 2 64 bits, the multilib variant is in core2/ relative to the main sysroot, with the libraries in lib64/ directory. So the first two variants are in the same sysroot, only the name of the directory for the libraries is different. Therefore, we introduce a new ARCH_LIB_DIR variable, which contains either 'lib' or 'lib64'. This variable is defined according to the location of the libc.a file for the selected multilib variant, and is then used when copying the libraries to the target and to the staging directory. In addition to this, we no longer use the -print-multi-directory to get the ARCH_SUBDIR, since in the case of the 64 bits variants of this toolchain, it returns just '64' and not a real path. Instead, we simply compute the difference between the arch-specific sysroot and the main sysroot. We also take that opportunity to expand the documentation on the meaning of the different variables.

support/check-kernel-headers: fix old custom toolchains without -print-sysroot Old toolchains, with old gcc that do not support -print-sysroot, break the kernel-headers version check script: it fails to find the sysroot of the toolchain, and thus ends up including the host's linux/version.h. Most of the time, this will break early, since the host's kernel headers will not match the toolchain settings. But it can happen that the check is succesful, although the configuration of the toolchain is wrong: - the custom toolchain has kernel headers vX.Y - the user selected vX.Z (Z!=Y) - the host has headers vX.Y In this case, the check passes OK, but the build of some packages later on will break (which is exactly what those _AT_LEAST_XXX options were added to avoid). Fix that by passing the sysroot to the check script, instead of the cross compiler. We get the sysroot as thus: - for custom toolchains, we use the macro toolchain_find_sysroot. We can do that, because we already have a complete sysroot with libc.a at that time. - for internal toolchain using a custom kernel headers version, we just use $(STAGING_DIR). We can't use the macro as for custom toolchains above, because at the time we install the kernel headers, we do not yet have a complete sysroot with a libc.a. But we can just use $(STAGING_DIR), since we're only interested in the kernel headers. For all other types of toolchains, we already have the _AT_LEAST_XXX options properly set, so we need not add a check in this case.

toolchain: print actual version of kernel headers when checking Since we introduced the _AT_LEAST_XXX for the kernel headers, people using pre-built custom toolchain now have to specify the version of the kernel headers their custom toolchain uses. So, when we detect that there is a mismatch between the selection in the menuconfig, and the actual version of the headers, we currently only bail out with a terse message "Incorrect selection of kernel headers". This could be confusing some, and getting the version of the headers used by the toolchain is not trivial (well, it's very easy, but not trivial.) This patch changes the way we report the error by moving the message into the test-code, and by printing the expected and actual versions of the kernel headers. BUT! To get this pretty error message, we need to run the test-program, so we can not use the cross-toolchain, we have to use the native one. BUT! The native one has its own linux/version.h header, so we can not simply include it. So, we ask the cross-compiler where its default sysroot is, and use that to then force-feed the cross linux/version.h to the native toolchain. [Thomas: augment commit log with a message provided by Yann, fix coding style to not have spaces after opening parenthesis and before closing parenthesis, reformatted the message "Incorrect selection..." to make it fit on one line.] Reported-by: Maxime Hadjinlian <maxime.hadjinlian@gmail.com> Signed-off-by: "Yann E.
