The Buildroot coding style defines one space around make assignments and
does not align the assignment symbols.
This patch does a bulk fix of offending packages. The package
infrastructures (or more in general assignments to calculated variable
names, like $(2)_FOO) are not touched.
Alignment of line continuation characters (\) is kept as-is.
The sed command used to do this replacement is:
find * -name "*.mk" | xargs sed -i \
-e 's#^\([A-Z0-9a-z_]\+\)\s*\([?:+]\?=\)\s*$#\1 \2#'
-e 's#^\([A-Z0-9a-z_]\+\)\s*\([?:+]\?=\)\s*\([^\\]\+\)$#\1 \2 \3#'
-e 's#^\([A-Z0-9a-z_]\+\)\s*\([?:+]\?=\)\s*\([^\\ \t]\+\s*\\\)\s*$#\1 \2 \3#'
-e 's#^\([A-Z0-9a-z_]\+\)\s*\([?:+]\?=\)\(\s*\\\)#\1 \2\3#'
Brief explanation of this command:
^\([A-Z0-9a-z_]\+\) a regular variable at the beginning of the line
\([?:+]\?=\) any assignment character =, :=, ?=, +=
\([^\\]\+\) any string not containing a line continuation
\([^\\ \t]\+\s*\\\) string, optional whitespace, followed by a
line continuation character
\(\s*\\\) optional whitespace, followed by a line
continuation character
Hence, the first subexpression handles empty assignments, the second
handles regular assignments, the third handles regular assignments with
line continuation, and the fourth empty assignments with line
continuation.
This expression was tested on following test text: (initial tab not
included)
FOO = spaces before
FOO = spaces before and after
FOO = tab before
FOO = tab and spaces before
FOO = tab after
FOO = tab and spaces after
FOO = spaces and tab after
FOO = \
FOO = bar \
FOO = bar space \
FOO = \
GENIMAGE_DEPENDENCIES = host-pkgconf libconfuse
FOO += spaces before
FOO ?= spaces before and after
FOO :=
FOO =
FOO =
FOO =
FOO =
$(MAKE1) CROSS_COMPILE=$(TARGET_CROSS) -C
AT91BOOTSTRAP3_DEFCONFIG = \
AXEL_DISABLE_I18N=--i18n=0
After this bulk change, following manual fixups were done:
- fix line continuation alignment in cegui06 and spice (the sed
expression leaves the number of whitespace between the value and line
continuation character intact, but the whitespace before that could have
changed, causing misalignment.
- qt5base was reverted, as this package uses extensive alignment which
actually makes the code more readable.
Finally, the end result was manually reviewed.

|
|
# This package 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
|
|
# * 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
|
|
#
|
|
# 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 still support 4.2.x (for
|
|
# AVR32) 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.
