Enter here the crosstool-NG's .config file to use.
If unsure, use the default.

Enable this option if you want your toolchain to support
files bigger than 2 GB.

help
Enable this option if you want your toolchain to support
IPv6.

Enable this option if you want your toolchain to support
RPC (needed for NFS, for example).

bool "Enable WCHAR support"
select BR2_USE_WCHAR
help
Enable this option if you want your toolchain to support
wide characters (i.e characters longer than 8 bits, needed
for locale support).

localization and internationalization.

select BR2_PROGRAM_INVOCATION
help
Enable this option if you want your toolchain to support the
GNU-specific program_invocation_name and
program_invocation_short_name strings. Some GNU packages
(like tar and coreutils) utilize these for extra useful
output, but in general are not required.

Enable this option if you want your toolchain to support the
C++ language and you want C++ libraries to be installed on
your target system.
