%description
The glibc package contains standard libraries which are used by
multiple programs on the system. In order to save disk space and
memory, as well as to make upgrading easier, common system code is
kept in one place and shared between programs. This particular package
contains the most important sets of shared libraries: the standard C
library and the standard math library. Without these two libraries, a
Linux system will not function.  The glibc package also contains
national language (locale) support.

This package now also provides ldconfig which was package seperately in
the past. Ldconfig is a basic system program which determines run-time
link bindings between ld.so and shared libraries. Ldconfig scans a running
system and sets up the symbolic links that are used to load shared
libraries properly. It also creates a cache (/etc/ld.so.cache) which
speeds the loading of programs which use shared libraries.

%description devel
The glibc-devel package contains the header and object files necessary
for developing programs which use the standard C libraries (which are
used by nearly all programs).  If you are developing programs which
will use the standard C libraries, your system needs to have these
standard header and object files available in order to create the
executables.

This package also includes the C header files for the Linux kernel.
The header files define structures and constants that are needed for
building most standard programs. The header files are also needed for
rebuilding the kernel.

Install glibc-devel if you are going to develop programs which will
use the standard C libraries.

%package static-devel
Summary:        Static libraries for GNU C library
Group:          Development/C
Requires:       %{name}-devel = %{glibcepoch}:%{glibcversion}-%{glibcrelease}
# ensure libxcrypt is installed as glibc crypt is disabled / being obsoleted
Requires:       %{_lib}xcrypt-static-devel >= 4.1.1-1

%description static-devel
The glibc-static-devel package contains the static libraries necessary
for developing programs which use the standard C libraries. Install
glibc-static-devel if you need to statically link your program or
library.

%package profile
Summary:        The GNU libc libraries, including support for gprof profiling
Group:          Development/C
Obsoletes:      libc-profile
Provides:       libc-profile = %{glibcversion}-%{glibcrelease}
Autoreq:        true

%description profile
The glibc-profile package includes the GNU libc libraries and support
for profiling using the gprof program.  Profiling is analyzing a
program's functions to see how much CPU time they use and determining
which functions are calling other functions during execution.  To use
gprof to profile a program, your program needs to use the GNU libc
libraries included in glibc-profile (instead of the standard GNU libc
libraries included in the glibc package).

If you are going to use the gprof program to profile a program, you'll
need to install the glibc-profile program.

%package -n nscd
Summary:        A Name Service Caching Daemon (nscd)
Group:          System/Servers
Requires(post):  systemd >= %{systemd_required_version}
Requires(post):  rpm-helper >= 0.24.8-1
Requires(preun): rpm-helper >= 0.24.8-1
Autoreq:        true

%description -n nscd
Nscd caches name service lookups and can dramatically improve
performance with NIS+, and may help with DNS as well. Note that you
can't use nscd with 2.0 kernels because of bugs in the kernel-side
thread support. Unfortunately, nscd happens to hit these bugs
particularly hard.

Install nscd if you need a name service lookup caching daemon, and
you're not using a version 2.0 kernel.

%if %{build_debug}
%package        debug
Summary:        Shared standard C libraries with debugging information
Group:          System/Libraries
Requires:       %{name} = %{glibcepoch}:%{glibcversion}-%{glibcrelease}
Autoreq:        false

%description debug
The glibc-debug package contains shared standard C libraries with
debugging information. You need this only if you want to step into C
library routines during debugging.

To use these libraries, you need to add %{_libdir}/debug to your
LD_LIBRARY_PATH variable prior to starting the debugger.
%endif

%package utils
Summary:        Development utilities from GNU C library
Group:          Development/Other
Requires:       %{name} = %{glibcepoch}:%{glibcversion}-%{glibcrelease}

%description utils
The glibc-utils package contains memusage, a memory usage profiler,
mtrace, a memory leak tracer and xtrace, a function call tracer which
can be helpful during program debugging.

If unsure if you need this, don't install this package.

%if %{build_i18ndata}
