libtool: fix build on systems with automake-1.11 (e.g. Fedora 10)

package/libtool/libtool-0001-mips64-n64-linking.patch touches an m4
file, so applying it triggers a run of autoconf, automake, etc. This
sometimes leads to build failures due to incompatible system autotools.
This was observed on Fedora 10, which has automake 1.11 while the
generated files that are included in the tarball require automake
1.11.1.

We cannot simply set HOST_LIBTOOL_AUTORECONF = YES because that would
create a circular dependency on host-libtool. Therefore, the patch
patch is applied on the installed libtool.m4 instead of in the source
tree. Then, it also needs to be renamed to something that doesn't
match buildroot's patch convention so it doesn't get picked up
automatically.

util-linux: libblkid needs fork(), disable on !MMU

The libblkid library in util-linux uses fork. While it seems
potentially possible to disable the parts of the library that use fork
(the only parts using fork are parts related to LVM and Device Mapper,
which are said to be legacy as they are replaced by sysfs based
scanning, instead of having to fork to run a separate process).

However, since libblkid is used by:

 - e2fsprogs, which uses lots of fork all over the place
 - udev, which most likely will also need fork

There is not much point in making libblkid fork-less. As a
consequence, this commit makes util-linux/libblkid unavailable on
non-MMU architectures, and propagates the relevant dependency to the
reverse dependencies of libblkid.

This fixes the e2fsprogs build failure seen on Blackfin. The failure
was due to a configure test of e2fsprogs which was trying to link a
small test program against libblkid, which failed because there was an
undefined reference to fork() in the libblkid code.

cairo: improve the Blackfin build fix

Patch cairo-001-blackfin-build-fix.patch was added in commit
d372d0b6777f52cd493dc0a892593d4390536ec5 ('cairo: add patch to fix
Blackfin build failure') to take into account the fact that Blackfin
has a non-empty USER_LABEL_PREFIX: C symbol 'foo' corresponds to
assembly symbol '_foo', contrary to most other architectures where
they are the same.

However, the patch was only fixing the relevant macros in
src/cairo-compiler-private.h and did not take into account the
duplicated version of these macros in

and the Makefile is not of the highest possible quality, so this
commit fixes the problem by introducing a "STATIC" variable that can
be set from the environment. When set to a non-empty value, the
Makefile assumes it should only build the static version of the
library.

Note that this package is in desperate need of some care: there is one
single patch that mixes several changes together, it doesn't have a
description or a Signed-off-by line, and there is now a github project
for libcgi at https://github.com/rafaelsteil/libcgi/ that has the same
fixes.

However, for the purpose of the master branch, we're doing the most
minimal fix possible, by just adding this STATIC variable.

manual: add explanations on limitations about using O=...

Using a relative path for O=... has limitations, since it is interpreted
relative to the Buildroot tree, and thus may lead to unexpected results.

For example, running this:
    make -C buildroot O=my-O

will not create my-O in the current working directory, but as a
sub-directory of the Buildroot tree, here in buildroot/my-O

Explain this in the manual (as is similarly done for BR2_EXTERNAL).
Also add a note that $(O) will be created if missing.

Also change O=.. and -C .. to O=<...> and -C <...> to make it explicit
this is an ellipse, not a relative path.

aiccu: disable on AVR32

In commit 87492d244a1dbf6114bb464e8d8dbedcf08fb399 ("aiccu: disable
for uClibc 0.9.31/0.9.32"), we made sure it was not possible to select
aiccu with uClibc 0.9.31 and 0.9.32, because they lack dn_skipname().

However, we still have the problem that external AVR32 toolchains can
select aiccu, which causes build failures. Therefore, we also disallow
aiccu on AVR32 altogether. We keep the 0.9.31/0.9.32 exclusions,
because if they are used on other architectures, it would also fail

evas: depend on thread support

Evas has an optional mechanism to do asynchronous preloading of
images. This mechanism is optional, and in commit
b6d92bf415df33ac86487d68f5f8299f406859d2 ("libevas: async image
preload support needs threads support in toolchain"), Peter made sure
to disable the asychronous preloading when no thread support was
available.

Unfortunately, it seems like disabling the asynchronous loading is
rarely used, and it in facts fails to build: a member of structure is
not present when asynchronous preloading is disabled, but the code
continues to use it.

Since the fix is not obvious, and all this mechanism seems to have
changed completely in EFL 1.8.x, and we probably don't care much about
EFL without threads, this commit adds a dependency of libevas on
thread support. Consequently, it also reverts commit
b6d92bf415df33ac86487d68f5f8299f406859d2 which is no longer necessary.

Of course, this commit propagates this additional dependency to the
reverse dependencies of libevas.

icu: not available when BR2_BINFMT_FLAT is used

icu does not recognize 'uclinux' as a supported platform. While making
it recognize uclinux is easy, there is another problem down the road:
icu does very weird things to generate an ELF library containing
static data (libicudata.a), and the generated library being ELF, it is
not compatible with the FLAT binary format expected by uclinux
platforms such as Blackfin in FLAT format.

Therefore, we simply disallow the selection of icu on FLAT
platforms.

Note that adding a dependency on BR2_BINFMT_ELF doesn't work, because
BR2_BINFMT_FDPIC is considered to be separate (even if technically
FDPIC is a derivative of ELF). That's why the dependency we're adding
is "depends on !BR2_BINFMT_FLAT" and not "depends on BR2_BINFMT_ELF".

dropbear: bump version

Fixes a number of issues. From the changelog:

- Avoid getting stuck in a loop writing huge key files, reported by Bruno
  Thomsen
- Avoid crash on exit due to cleaned up keys before last packets are sent,
  debugged by Ronald Wahl
- Fix a race condition in rekeying where Dropbear would exit if it received a
  still-in-flight packet after initiating rekeying. Reported by Oliver Metz.
  This is a longstanding bug but is triggered more easily since 2013.57
- Ensure that generated RSA keys are always exactly the length
  requested. Previously Dropbear always generated N+16 or N+15 bit keys.
  Thanks to Unit 193
- Fix DROPBEAR_CLI_IMMEDIATE_AUTH mode which saves a network round trip if the
  first public key succeeds. Still not enabled by default, needs more
  compatibility testing with other implementations.
- Fix signal handlers so that errno is saved, thanks to Erik Ahlén for a patch
  and Mark Wickham for independently spotting the same problem.

And at the same time get rid of the TIMEVAL_TO_TIMESPEC as dropbear provides a
fallback implementation if not available (and has done so since 2006).

host python/python3: conditionally disable unicodedata

The host python always had --disable-unicodedata, regardless of the
corresponding configuration option BR2_PACKAGE_PYTHON_UNICODEDATA.
Since the host python is used to byte-compile python modules, this meant
that such modules could not contain unicode strings. For example, following
statement in a python module:
    print u"\N{SOLIDUS}"

would cause the byte-compilation to fail with message:
    SyntaxError: ("(unicode error) \\N escapes not supported (can't load
    unicodedata module)",

Instead, conditionally disable unicodedata based on
BR2_PACKAGE_PYTHON_UNICODEDATA, also for the host python.

This fixes bug #6542 (https://bugs.busybox.net/show_bug.cgi?id=6542)

qtuio: correct install-target/staging when Qt library type is 'static'

If BR2_PACKAGE_QT_STATIC is set, qtuio will not build a .so file, but .a.
However, the custom INSTALL_TARGET_CMDS and INSTALL_STAGING_CMDS
unconditionally attempted to copy the .so file.

This commit checks the requested Qt library type and copies the right
library for each case, taking into account that the static .a file does not
need to be copied to the target directory.

vlc: explicitly disable opencv support

vlc can use opencv in video filters, but it requires a couple of
features enabled in opencv; so, simply force disabling opencv support.

Note that vlc does includes the legacy opencv/cv.h header, which pulls a

vlc: needs dependency on host-lua if Lua is selected

If Lua support is requested in VLC, its configure script tries to find the
luac byte compiler, which fails if host-lua is not yet built.

This can be easily reproduced by setting a minimal config with vlc and Lua
enabled, and running: 'make clean toolchain vlc'. Final output is:

checking for LUA... no
configure: WARNING: Package lua5.2 was not found in the pkg-config search path.
Perhaps you should add the directory containing `lua5.2.pc'
to the PKG_CONFIG_PATH environment variable
No package 'lua5.2' found, trying lua 5.1 instead
checking for LUA... no
configure: WARNING: Package lua5.1 was not found in the pkg-config search path.
Perhaps you should add the directory containing `lua5.1.pc'
to the PKG_CONFIG_PATH environment variable
No package 'lua5.1' found, trying lua >= 5.1 instead
checking for LUA... yes

configure: error: Could not find the LUA byte compiler.
make: *** [<buildroot>/output/build/vlc-2.1.2/.stamp_configured] Error 1

Fix this problem by setting host-lua as a dependency to vlc.

opencv: always enable opencv_core module when opencv is enabled

It does not make much sense enabling opencv without its core module.

This configuration leads to build nothing (since all modules depend on
the core one), but install the configuration files (*.pc and *.cmake)
anyway.

This absurd situation may break the build-system of other packages
that would correctly find the *.pc (but does not check for the modules
they actually use), but would not build because of missing headers and
libraries.

jimtcl: don't attempt to handle ccache internally

jimtcl tries to use 'ccache' (a non-buildroot host version) which may not
exist on the host system. If ccache is enabled in buildroot, the compiler
used by jimtcl is:
ccache <buildroot>/.../ccache <buildroot>/.../<tuple>-gcc

If ccache is not present on the host, this results in the build error:

ccache <buildroot>/.../ccache <buildroot>/.../<tuple>-gcc
-D_GNU_SOURCE -Wall  -I. -fpic -pipe -Os    -c -o jim-subcmd.o jim-subcmd.c
make[1]: ccache: Command not found

This patch passes 'CCACHE=none' to the 'configure' script, disabling the
internal handling of ccache, so that ccache can be transparently passed
through CC.
