## SECTION=libc
config GLIBC
tristate
select BASE if RUNTIME
if GLIBC
menu "glibc "
comment "Install options"
config GLIBC_LD
bool
help
This is the dynamic loader (e.g.: "/lib/ld-2.8.90.so")
You don't want to deselect this, unless you have a pure
static system. This is why this options hasn't a prompt.
config GLIBC_C
bool
default y
prompt "Install libc"
select GLIBC_LD
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
prompt "Install libpthread"
help
If at least one application on the target uses threads when executed
this library will be required.
config GLIBC_THREAD_DB
bool
prompt "Install libthread_db"
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_RT
bool
prompt "Install librt"
help
Functions in this library provide most of the interfaces specified by
the POSIX.1b Realtime Extension
config GLIBC_DL
bool
prompt "Install libdl"
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
prompt "Install libcrypt"
help
The encryption/decryption library
config GLIBC_UTIL
bool
prompt "Install libutil"
help
Contains code for "standard" functions used in many different Unix
utilities.
config GLIBC_M
bool
prompt "Install libm"
help
If at least one application on your target does any kind of math
calculation, you should install this library.
config GLIBC_ANL
bool
prompt "Install libanl"
help
libanl is an asynchronous name lookup library, originating in Bind.
config GLIBC_NSS_DNS
bool
prompt "Install libnss_dns"
select GLIBC_RESOLV
help
Contains functions for name resolution to ip addresses and vice versa
config GLIBC_NSS_FILES
bool
prompt "Install libnss_files"
help
Contains functions to access some vital system control files (for
login for example) and for name resolution to ip addresses.
NSS is the "Name Service Switch", controlled by /etc/nsswitch.conf
config GLIBC_NSS_HESIOD
bool
prompt "Install libnss_hesiod"
select GLIBC_RESOLV
select GLIBC_NSS_FILES
help
Adds the hesiod libnss source for user lookups
config GLIBC_NSS_NIS
bool
prompt "Install libnss_nis"
select GLIBC_NSL
select GLIBC_NSS_FILES
help
Adds the NIS (NIS version 2), also called YP, libnss source
config GLIBC_NSS_NISPLUS
bool
prompt "Install libnss_nisplus"
select GLIBC_NSL
help
Adds the NIS+ (NIS version 3) libnss source
config GLIBC_NSS_COMPAT
bool
prompt "Install libnss_compat"
select GLIBC_NSL
help
Adds the NIS libnss source on compat mode
config GLIBC_RESOLV
bool
prompt "Install libresolv"
# select GLIBC_NSS_FILES
# select GLIBC_NSS_DNS
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"
You will also need libnss_files if this name resolution should base
on local files like /etc/hosts and libnss_dns if the name resolution
should work with an external dynamic name resolution service. You
will need both libraries if your /etc/nsswitch.conf contains a line
like "hosts: file dns"
config GLIBC_NSL
bool
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_GETENT
bool
prompt "Install getent"
help
getent is a tool to get entries from Name Service Switch
libraries
config GLIBC_LDCONFIG
bool
prompt "Install ldconfig"
help
ldconfig creates a shared library cache, which reduces the number
of library locations, the loader needs to check, significantly and
therefore improves launch times for programs.
config GLIBC_LDCONFIG_RC_ONCE
bool
prompt "Create /etc/ld.so.cache"
depends on GLIBC_LDCONFIG
help
The ld.so.cache is generated once at first boot. If you update your
libraries later on at runtime, you have to make sure to update the
cache as well. See /etc/rc.once.d/ldconfig
config GLIBC_I18N_BIN_LOCALE
bool
prompt "Install locale"
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"
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
unnecessarily 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.
