Currently, HOSTCC and HOSTCXX are set to their _NOCACHE variants in the
'dependencies' target. This is needed because at that time, ccache is
not built yet - host-ccache is one of the dependencies. However, because
this override is only specified for the 'dependencies' target (and
thereby gets inherited by its dependencies), the override is only
applied when the package is reached through the 'dependencies' target.
This is not the case when one of DEPENDENCIES_HOST_PREREQ is built
directly from the command line, e.g. when doing 'make host-ccache'. So
in that case, ccache will be built with ccache... which fails of
course.
To fix this, directly apply the override to the DEPENCIES_HOST_PREREQ
targets.
Note that this only fixes the issue for 'make host-ccache', NOT for
e.g. 'make host-ccache-configure'.

Recently, the autoconf macros for libtool started using '/usr/bin/file'
to determine the type of library that is generated by the toolchain.
Packages that use this recent version of the libtool autoconf macros
will fail in a rather dramatic way when /usr/bin/file is not present
on the host: the package will still build but no shared library is
generated, which in turn may cause build failures in other packages
that link with it.
For example, libpng's configure determines that it is not possible to
build a shared library on MIPS64 because the expected output from 'file'
is not present. Therefore, only a static libpng.a is built. Later,
bandwithd links with -lpng but it doesn't use the pkg-config's
Private-Libs (because it's not linking statically) and it doesn't have
access to the NEEDED reference from the shared library. Therefore, it
doesn't link with zlib and fails with
pngrutil.c:(.text+0x55c): undefined reference to `inflate'
We cant use host-file because it is itself an autotools package and is
itself using libtool, so this would be a chicken-n-egg problem. Besides,
the libtool script really wants to call /usr/bin/file, so it would not
even find our host-file anyway.
So, just require that '/usr/bin/file' is present on the host.

Currently all cmake packages depend on host-cmake. Unfortunately
host-cmake takes a long time to configure and build: almost 7 minutes
on a dual-core i5 with SSD. The time does not change even with ccache
enabled.
Indeed, building host-cmake is avoidable if it is already installed on
the build host: CMake is supposed to be quite portable, and the only
patch in Buildroot for the CMake package seems to only affect
target-cmake.
Thus we automatically skip building host-cmake and use the one on the
system if:
- cmake is available on the system and
- it is recent enough.
First, we leverage the existing infrastructure in
support/dependencies/dependencies.mk to find out whether there's a
suitable cmake executable on the system. Its path can be passed in the
BR2_CMAKE environment variable, otherwise it defaults to "cmake". If
it is enabled, found and suitable then we set BR2_CMAKE_HOST_DEPENDENCY
to empty; otherwise we set BR2_CMAKE_HOST_DEPENDENCY to 'host-cmake' and
override BR2_CMAKE with "$(HOST_DIR)/usr/bin/cmake" to revert to using
our own cmake (the old behaviour).
Then in pkg-cmake.mk we replace the hard-coded dependency on host-cmake
to using the BR2_CMAKE_HOST_DEPENDENCY variable, and we use $(BR2_CMAKE)
instead of $(HOST_DIR)/usr/bin/cmake.
Unlike what we do for host-tar and host-xzcat, for host-cmake we do
not add host-cmake to DEPENDENCIES_HOST_PREREQ. If we did, host-cmake
would be a dependency for _any_ package when it's not installed on the
host, even when no cmake package is selected.
Cmake versions older than 3.0 are affected by the bug described and
fixed in Buildroot in ef2c1970e4 ("cmake: add patch to fix Qt mkspecs
detection"). The bug was fixed in upstream CMake in version 3.0 [0].
Amongst all the cmake packages currently in Buildroot, the currently
highest version mentioned in cmake_minimum_required() is 3.1 (grantlee
and opencv3).
Thus we use 3.1 as the lowest required cmake for now, until a package is
bumped, or a new package added, with a higher required version.

The introduction of <pkg>_STRIP_COMPONENTS broke the build of the
target tar package, because support/dependencies/check-host-tar.mk
defines TAR_STRIP_COMPONENTS to --strip-components. Which leads to
have the package infrastructure do:
$$(TAR_STRIP_COMPONENTS)=$$($(2)_STRIP_COMPONENTS)
which for the tar package evaluates to:
$$(TAR_STRIP_COMPONENTS)=$$(TAR_STRIP_COMPONENTS)
which evalutes to:
--strip-components=--strip-components
Which obviously doesn't work really well. And in fact the
TAR_STRIP_COMPONENTS definition in
support/dependencies/check-host-tar.mk is no longer necessary: it was
needed in the days where we were trying to support old tar versions
that did not support --strip-components. But nowadays, when such an
old tar version is encountered, we build our own host-tar which
supports --strip-components.

When we set LD_LIBRARY_PATH when building our host tools, we append any
pre-existing value to our custom path:
LD_LIBRARY_PATH="$(HOST_DIR)/usr/lib:$(LD_LIBRARY_PATH)"
But then if LD_LIBRARY_PATH was previously empty, we end up with an
LD_LIBRARY_PATH that ends with a colon.
Also, when we check that an existing LD_LIBRARY_PATH does not contain
CWD, we previously did not look for a zero-length prefix.
Since 'man ld.so' says of LD_LIBRARY_PATH:
A colon-separated list of directories in which to search for ELF
libraries at execution-time. Similar to the PATH environment
variable.
And POSIX states about PATH:
A zero-length prefix is a legacy feature that indicates the current
working directory.
And bash also recognises a zero-length prefix to search in CWD:
A zero-length (null) directory name in the value of PATH indicates
the current directory.
We may thus end up on a system where a zero-length prefix in
LD_LIBRARY_PATH is interpreted as CWD.
Do not append the previous LD_LIBRARY_PATH if it was empty, and check
for a zero-length prefix when checking dependencies.

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.

XBMC needs Java on the host in order to build, because it uses a
code-generator which is built in two phases: In the first phase SWIG is used
to parse C++ header files that define the API. SWIG outputs an XML file
that contains a complete description of the structure of the API. In the
second phase, the XML file is ingested by a Groovy (Java) program that then
creates C++ code that forms the bridge to the scripting language (Python).
The second phase is why we need java on the host.

The dependencies-source, dependencies-clean and dependencies-dirclean
targets are not needed, as long as 'dependencies' is not used in the
<pkg>_DEPENDENCIES of a package.

If xzcat is not present on the host system, buildroot bails out early asking
the developer to install it (xzcat is now a DL_TOOLS_DEPENDENCY)
Conversely, when BR2_TARGET_ROOTFS_CPIO_XZ is enabled, then host-xz is a
build dependency, and no manual action is required from the developer.
Because the second approach is nicer, also build host-xz when xzcat is not
available, using the host-prerequisite and suitable-host-pkg mechanisms,
already used for tar.

Make 3.82 no longer sort the result of wildcards (see
http://comments.gmane.org/gmane.comp.gnu.make.bugs/4260). This may break
build reproducibility.
This patch sort results of wildcards to ensure reproducibility.

This patch moves the host-ccache build target from BASE_TARGETS in Makefile
to an actual host prerequisite in support/dependencies. This causes
host-ccache to be built as part of the dependencies, before any real package
is built.
Since the dependencies are built without ccache anyway, there is no need to
set HOST_CCACHE_CONF_ENV anymore.

This patch forces the plain host compiler to be used during the building of
dependencies, without ccache as it is not yet built.
