Currently, patches with renames are refused, as they reqire patch 2.7
or newer. So far, we did not require that version because it was too
recent to be widely available.
But patch 2.7 has been released in 2012, almost 9 years ago now; it is

In Makefiles, variables are split, filtered, and otherwise mangled on
a space as a separator. In a shell, they will also be split on TABs.
We split and filter and iterate on variables in a lot of places, and
most importantly, spaces in PATH is very seldom tested, if at all, so
a lot of packages will not be working properly in such a situation.
For example, the config.guess contains constructs that are not resilient
to a space in PATH:
PATH=$PATH:/.attbin ; export PATH
Also, our fakedate will iterate over PATH:
for P in `echo $PATH | tr ':' ' '`; do
Those are only two cases, but the first means basically all
autotools-based packages are susceptible to subtle breakage.
Furthermore, Buildroot itself does not support that the top-level or
output directories are in a path with spaces anyway.
So, instead of chasing all cases that might be potentially broken,
let's just detect the case and bail out, like we already do when PATH
contains a \n, or when it contains the current working directory.

apply-patches currently blindly removes *.orig / .*.orig files as GNU patch
by default writes these as backup files when patches only apply with fuzz.
This is unfortunate as package sources may contain files ending in .orig as
well, breaking the build. Luckily GNU patch can be told to not write these
backup files using the --no-backup-if-mismatch option, so used that instead
of the .orig removal step.
--no-backup-if-mismatch is supported since GNU patch 2.3.8 (1997-06-17) and
busybox patch if built with CONFIG_DESKTOP, but E.G. isn't supported by the
BSD patch, so add logic to dependencies.sh to error out if patch doesn't

Currently, we only require a gcc 4.4 version, which now is pretty old
(released in April 2009). This requirement is not even tested nowadays,
with our oldest autobuilder having a 4.7 version only.
And even then, 4.7 is still old enough that it prevents us from
upgrading some packages. For example cmake 3.10+ requires C++11
constructs that were only added in gcc 4.8 (when C++11 support was
finally completed in gcc).
So, update our requirements for gcc to at least 4.8.

Older distributions such as CentOS6 come with python2.6, which causes build
failures in packages such as host-libglib2 because they require python2.7 and
above.
host-libglib2 will produce the error message:
/bin/sh: python2.7: command not found
Python2.7 is a hard-coded value in configure.ac. If one changes the value to
just "python," the following stack trace is produced:
Traceback (most recent call last):
File "./gdbus-2.0/codegen/gdbus-codegen.in", line 55, in <module>
self.outfile.write(LICENSE_STR.format(config.VERSION))
ValueError : sys.exit(codegen_main.codegen_main())
zero length field name in format
Instead of supporting an ancient version of Python that had its support ended
in October os 2013, it would be more pragmatic only to support Python2.7 and
above.
Luckily; CentOS6 has the centos-release-scl repository, which allows users to
install python2.7, and Debian 8 comes with Python2.7 already, making this patch
relatively low impact.

A person on IRC reported a build failure with the util-linux package,
looking like this:

cd /home/aep/consulting/chargery/tracker/output/target/usr/bin && ln -sf setarch $I ; \

/bin/sh: line 1: ./ln: cannot execute binary file: Exec format error
/bin/sh: line 1: ./ln: cannot execute binary file: Exec format error
The issue was an empty path in the PATH variable, which means "current
working directory", causing a "ln" binary built by util-linux for the
target to be used instead of the system-provided "ln".
We already check a number of things in the PATH and LD_LIBRARY_PATH
variables in support/dependencies/dependencies.sh, but we were not
checking that PATH did not contain an empty path.
This commit fixes that and takes this opportunity to simplify the test
code for PATH and LD_LIBRARY_PATH.

matching locales.
Also, quote the regexp, so that the '?' and '$' are not interpreted by

The script support/scripts/check-uniq-files uses the argparse Python
module. In most recent Python versions (starting with 2.7), the
argparse module is part of the standard library, and we already check
for the availability of Python in
support/dependencies/dependencies.sh.
However, when running on an ancient distribution with Python 2.6, the
argparse module is not part of the Python standard library, but
available as an external module. Without this module, the build fails,
because check-uniq-files, which is used in target-finalize, fails to
run.

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.

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.

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.

Some bootloaders (such as Grub) need to be built for x86 (i.e IA32)
even if the target architecture is x86-64. However, when the target
architecture is x86-64, the cross-compiler generated by Buildroot is
not able to generate 32 bits code.
To solve this, we will rely on the host compiler being a x86 + x86-64
compiler. Therefore, this commit introduces the
BR2_HOSTARCH_NEEDS_IA32_COMPILER option, which tells the dependency
checking logic to verify that the host compiler is indeed capable of
