menuconfig GLIBC
bool
default y
prompt glibc
help
This menu entry lets you select components from the standard
C library called glibc. It depends on the system what components are
required.
config GLIBC_VERSION
prompt "glibc Version"
string
default "2.5"
depends on GLIBC
comment "Install options"
depends on GLIBC
config GLIBC_LIBC
bool
depends on GLIBC
default y
prompt "Install libc on the target"
help
Any Unix-like operating system needs a C library:
the library which defines the "system calls" and
other basic facilities such as open, malloc, printf,
exit...
The GNU C library is used as the C library in the
GNU system and most systems with the Linux kernel.
Better not turn this option off..
config GLIBC_PTHREAD
bool
depends on GLIBC
prompt "Install libpthread on the target"
help
If at least one application on the target uses threads when executed
this library will be required.
config GLIBC_THREAD_DB
bool
depends on GLIBC
prompt "Install libthread_db on the target"
help
If at least one application on the target uses threads when executed
and you are going to debug this application (also remotely!), this
library will be required. You can omit this library, if you never
intend to debug multithread application on your target.
config GLIBC_LIBRT
bool
depends on GLIBC
prompt "Install librt on the target"
help
Functions in this library provide most of the interfaces specified by
the POSIX.1b Realtime Extension
config GLIBC_DL
bool
depends on GLIBC
prompt "Install libdl on the target"
help
libdl.so is a dynamic linking library that is generally of use only for
porting applications. If you are porting a BeOS application that requires
dlopen, dlclose, dlerror, dlsym, dladdr, or dlfcn.h, then you can use this
library.
libdl.so is a wrapper to the add-on functions with the semantics of the dl
(dynamic linking) library. This is used for finding shared objects at run
time. If the items are not found the program can continue to run.
It is extremely similar to the add-on mechanism in BeOS with some semantics
changes. If you are developing your own app, you almost definitely want to
use add-ons unless you are already familiar with libdl. In this case you may
be disappointed since it is possible that I have implemented part of it wrong.
If you want your application to have cross platform compatibility with this
functionality you should probably use libtool instead. It is much more cross
platform compatible than dlopen, etc. It also supports BeOS. See related links.
config GLIBC_CRYPT
bool
depends on GLIBC
prompt "Install libcrypt on the target"
help
The encryption/decryption library
config GLIBC_UTIL
bool
depends on GLIBC
prompt "Install libutil on the target"
help
Contains code for "standard" functions used in many different Unix
utilities.
config GLIBC_LIBM
bool
depends on GLIBC
prompt "Install libm on the target"
help
If at least one application on your target does any kind of math
calculation, you should install this library.
config GLIBC_NSS_DNS
bool
depends on GLIBC
prompt "Install libnss_dns"
select GLIBC_RESOLV
help
Contains functions for name resolution to ip addresses and vice versa
config GLIBC_NSS_FILES
bool
depends on GLIBC
prompt "Install libnss_files"
help
Contains functions to access some vitale system control files (for
login for example)
config GLIBC_NSS_HESIOD

config GLIBC_RESOLV
bool
depends on GLIBC
prompt "Install libresolv"
help
This library is required for creating, sending, and interpreting
packets to and from the internet domain name service. This library
needs some file for configuration: /etc/nsswitch.conf and /etc/resolv.conf.
Refer man pages for both files and how to setup them. To use any kind
of DNS, you must provide your own /etc/nsswitch.conf and
/etc/resolv.conf files. See menu "Root Filesystem -> config files -> /etc/nsswitch.conf"
config GLIBC_NSL
bool
depends on GLIBC
prompt "Install libnsl"
help
Functions in this library provide routines that provide a
transport-level interface to networking services like i.E.
nis(+)
config GLIBC_I18N_BIN_LOCALE
bool
prompt "Install locale"
depends on GLIBC
help
The locale program writes information about the current
locale environment, or all locales, to standard output.
config GLIBC_I18N_BIN_LOCALEDEF
bool
prompt "Install localedef"
depends on GLIBC
help
The localedef program reads the indicated charmap and
input files, compiles them to a binary form quickly usable
by the locale functions in the C library, and add it to
/usr/lib/locale/locale-archive
config GLIBC_I18N_RAWDATA
bool
prompt "Install i18n locales and charmaps"
depends on GLIBC_I18N_BIN_LOCALEDEF
help
With the i18n datasets you can generate new locales in running
system. This will, however, increase the installation size
unneccessarily if you don't want to change your system locale
often. Hence we recommend to use the "System locale" option in
ptxdist to determine locales while building the system.

install the iso8859-1 (Latin Alphabet No.1) and the iso8859-15 (Latin
Alphabet No.9) encoding modules into gconv, this should be ok for most
western languages
