help
Explicitly specify what locales to install on target. If N
then all locales supported by packages are installed.
config BR2_ENABLE_LOCALE_WHITELIST
string "Locales to keep"
default "C en_US de fr"
depends on BR2_ENABLE_LOCALE_PURGE
help
Whitespace seperated list of locales to allow on target.
Locales not listed here will be removed from the target.
See 'locale -a' on your host for a list of locales available
on your build host, or have a look in /usr/share/locale in
the target file system for available locales.
Notice that listing a locale here doesn't guarantee that it
will be available on the target - That purely depends on the
support for that locale in the selected packages.

Generate support for a list of locales. Locales can be
specified with or without encoding, when no encoding is
specified, UTF-8 is assumed. Examples of locales: en_US,
fr_FR.UTF-8.
config BR2_TOOLCHAIN_GLIBC_GCONV_LIBS_COPY
bool "Copy gconv libraries"
depends on BR2_TOOLCHAIN_USES_GLIBC
help
The gconv libraries are used to convert between different
character sets (charsets).
Say 'y' if you need to store and/or display different charsets.
config BR2_TOOLCHAIN_GLIBC_GCONV_LIBS_LIST
string "Gconv libraries to copy"
depends on BR2_TOOLCHAIN_GLIBC_GCONV_LIBS_COPY
help
Set to the list of gconv libraries to copy.
Leave empty to copy all gconv libraries.
Specify only the basename of the libraries, leave
out the .so extension. Eg.:
IBM850 ISO8859-15 UNICODE
Note: the full set of gconv libs are ~8MiB (on ARM).
# glibc and eglibc directly include gettext, so a separatly compiled
# gettext isn't needed and shouldn't be built to avoid conflicts. Some
# packages always need gettext, other packages only need gettext when
# locale support is enabled. See the documentation for how packages
# should rely on the following two options.

If your target has a MMU, you should say Y here. If you
are unsure, just say Y.

help
Optimizations to use when building for the target host.
NOTE: gcc optimization level is defined in build options.

help
Extra options to pass to the linker when building for the target.
Note that options with a '$' sign (eg. -Wl,-rpath='$ORIGIN/../lib')
are not supported.
config BR2_ECLIPSE_REGISTER

help
This options tells Buildroot to generate the necessary
configuration files to make your toolchain appear within
Eclipse, through the Eclipse Buildroot plugin.
# Options for packages to depend on, if they require at least a
# specific version of the kernel headers.
# Toolchains should choose the adequate option (ie. the highest
# version, not all of them).
