We cannot simply disable dtc support and patching the kernel makefiles
is risky and error-prone, so let's just install the host-dtc headers at

Commits 495e757d2 (package/dtc: add optional libyaml dependency) and
e43d9072a (package/dtc: fix build without libyaml), added a conditional
dependency to host-pkgconf, when libyaml is enabled, while commit
56d6dd453 (package/dtc: disable valgrind) explicitly disabled support of
valgrind.
However, presence of libyaml, as well as that of valgrind, *is* detected
by calling pkg-config:
NO_VALGRIND := $(shell $(PKG_CONFIG) --exists valgrind; echo $$?)
NO_YAML := $(shell $(PKG_CONFIG) --exists yaml-0.1; echo $$?)
Passing NO_YAML=1 or NO_VALGRIND=1 do not prevent the tests from being
executed, which would yield messages like:
/bin/sh: 1: /home/ymorin/dev/buildroot/O/host/bin/pkg-config: not found
(note however that, even if the test is executed, the value we pass on
the command line still takes precedence, and the support for either is
properly disabled.)
So, move the dependency on host-pkgconfig out of the condition. Ditto
for the host package.

With recent dtc but old u-boot, compilation issues occur related to libfdt.
These problems really are u-boot issue since it does not properly set
include paths so that its own headers are included. Nevertheless, since the
u-boot version is typically decided by users and stuck at some version
provided by a SoC or board vendor, it is not feasible to fix those old
versions.
Instead, already several fixes were made in the past, in Buildroot.
See commits:
c7ffd8a75d "package/dtc: fix include guards for older kernel/u-boot"
f437bf547c "uboot: fix build for older uboot source trees"
bf73334232 "uboot: fix build when libfdt-devel is installed system-wide"
0bf80e4bcd "uboot: ensure host includes are searched before system default
includes"
b15a7a62d3 "uboot: revert "uboot: use local libfdt.h""
baae5156ce "uboot: use local fdt headers"
3a6573ccee "uboot: use local libfdt.h"
Commit c7ffd8a75d fixes the problem caused by
dtc having changed their include guards from _FOO_H to FOO_H (leading
underscore removed). Old u-boot would still use _FOO_H, which (combined with
host-dtc headers that use FOO_H) would cause the inclusion of two different
copies of the same nominal include file, e.g. libfdt.h or libfdt_env.h,
causing 'error: redefinition of xxx' compilation issues.
The fix sets the 'new' include guard when the 'old' one is detected,
preventing a second inclusion of the same nominal file.
For some u-boot versions, however, this change not only needs to be made in
libfdt.h and libfdt_env.h, but also in 'fdt.h'.
Update the dtc patch to do just that.

1.4.6, and fixed post-1.4.7. This commit backports the upstream commit
to resolve this Assertion Error.
The build error was:

U-Boot has a copy of dtc in-tree. However, it has a bug in its build
system which could result in both one of the in-tree dtc include files
and the same host-installed include file to be #included.
Normally, that wouldn't be a problem, because (a) the two include files
are compatible, so it doesn't matter which one you include, and (b) the
include guards are the same in both, so only one of them really does
get included. However, upstream dtc has changed the include guards,
removing the leading underscore. Therefore, now the header file does
get included twice, which leads to multiple definitions like:
/builds/buildroot.org/buildroot/output/host/include/libfdt.h:1790:19: error: redefinition of 'fdt_appendprop_cell'
static inline int fdt_appendprop_cell(void *fdt, int nodeoffset,

tools/../include/libfdt.h:1656:19: note: previous definition of 'fdt_appendprop_cell' was here
static inline int fdt_appendprop_cell(void *fdt, int nodeoffset,
^~~~~~~~~~~~~~~~~~~
To fix this, patch (host) dtc to accept the old include guard as well,
which restores the old behaviour. This patch is probably not
upstreamable, since it's really a hack to work around an issue in
U-Boot. Note that it has been fixed upstream, but Buildroot supports
building older versions of U-Boot as well.
Note that the problem may still occur if you have libdtc-dev installed
on the host. However, now there is a simple workaround: enable
BR2_TARGET_UBOOT_NEEDS_DTC.
Note that a similar problem also occurs with the beaglebone fork of the
kernel. It's not clear if it has been fixed there.

The pylibfdt in dtc is new since 1.4.5, and therefore built since the
bump from 1.4.4 to 1.4.7 in commit
7b929ddcf0. Unfortunately, this Python
support causes a number of build failures, be it for host-dtc or dtc.
Since this Python support is not used/needed by anything in Buildroot
at this point, let's simply disable it by passing NO_PYTHON=1. While
doing this, introduce DTC_MAKE_OPTS and HOST_DTC_MAKE_OPTS to avoid
duplicating the variables several times.

Having a host variant of dtc is needed for example for U-Boot, which
uses the Device Tree for a number of platforms.
In addition, now that we have a proper host-dtc package, it is no
longer needed for the linux package to install the host dtc compiler:
users interested in having the host dtc compiler can simply enable
this package.
A Config.in.host option is added to build host-dtc, because the
initial reason why the host DTC built by the kernel was installed in
$(HOST_DIR)/usr/bin (commit 707d44d0a2
from Thomas DS) was:
Having dtc as a host tool can be useful for users that have a
custom boot scenario where the device tree is not embedded in the

Since a while, the semantic of BR2_PREFER_STATIC_LIB has been changed
from "prefer static libraries when possible" to "use only static
libraries". The former semantic didn't make much sense, since the user
had absolutely no control/idea of which package would use static
libraries, and which packages would not. Therefore, for quite some
time, we have been starting to enforce that BR2_PREFER_STATIC_LIB
should really build everything with static libraries.
As a consequence, this patch renames BR2_PREFER_STATIC_LIB to
BR2_STATIC_LIBS, and adjust the Config.in option accordingly.
This also helps preparing the addition of other options to select
shared, shared+static or just static.
Note that we have verified that this commit can be reproduced by
simply doing a global rename of BR2_PREFER_STATIC_LIB to
BR2_STATIC_LIBS plus adding BR2_PREFER_STATIC_LIB to Config.in.legacy.

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.
