config HAVE_SHARED
	bool "Enable support for shared libraries"

	default y
	help
	  If you wish to build uClibc with support for shared libraries then
	  answer Y here.  If you only want to build uClibc as a static library,
	  then answer N.

config FORCE_SHAREABLE_TEXT_SEGMENTS
	bool "Only load shared libraries which can share their text segment"
	depends on HAVE_SHARED
	select DOPIC
	default n
	help
	  If you answer Y here, the uClibc native shared library loader will
	  only load shared libraries, which do not need to modify any non-writable
	  segments. These libraries haven't set the DT_TEXTREL tag in the dynamic
	  section (==> objdump). All your libraries must be compiled with
	  -fPIC or -fpic, and all assembler function must be written as position
	  independent code (PIC).
	  Enabling this option will make uClibc's shared library loader a
	  little bit smaller and guarantee that no memory will be wasted by badly
	  coded shared libraries.

config LDSO_LDD_SUPPORT
	bool "Native 'ldd' support"
	depends on HAVE_SHARED
	default y
	help
	  Enable this to enable all the code needed to support traditional ldd,
	  which executes the shared library loader to resolve all dependencies
	  and then provide a list of shared libraries that are required for an
	  application to function.  Disabling this option will makes uClibc's
	  shared library loader a little bit smaller.  Most people will answer Y.

config LDSO_CACHE_SUPPORT
	bool "Enable library loader cache (ld.so.conf)"
	depends on HAVE_SHARED
	default y
	help
	  Enable this to make use of /etc/ld.so.conf, the shared library loader
	  cache configuration file to support for non-standard library paths.
	  After updating this file, it is necessary to run 'ldconfig' to update
	  the /etc/ld.so.cache shared library loader cache file.

config LDSO_PRELOAD_FILE_SUPPORT
	bool "Enable library loader preload file (ld.so.preload)"
	depends on HAVE_SHARED

	depends on HAVE_SHARED && (LDSO_CACHE_SUPPORT || LDSO_PRELOAD_FILE_SUPPORT)
	default "ld.so"
	help
	  If you wish to support both uClibc and glibc on the same system, it
	  is necessary to set this to something other than "ld.so" to avoid
	  conflicts with glibc, which also uses "ld.so".  This prevents both
	  libraries from using the same /etc/ld.so.* files.  If you wish to
	  support both uClibc and glibc on the same system then you should set
	  this to "ld-uClibc.so".

	  Most people will leave this set to the default of "ld.so".

	  WARNING: Changing the default prefix could cause problems with
	           binutils' ld !

config UCLIBC_STATIC_LDCONFIG
	bool "Link ldconfig statically"
	depends on HAVE_SHARED
	default y
	help
	  Enable this option to statically link the ldconfig binary.

	  Making ldconfig static can be beneficial if you have a library
	  problem and need to use ldconfig to recover.  Sometimes, it is
	  preferable to instead keep the size of the system down, in which
	  case you should disable this option.

config LDSO_RUNPATH
	bool "Enable ELF RUNPATH tag support"
	depends on HAVE_SHARED
	default y
	help
	  ELF's may have dynamic RPATH/RUNPATH tags.  These tags list paths 
	  which extend the library search paths.  They are really only useful 
	  if a package installs libraries in non standard locations and 
	  ld.so.conf support is disabled.

	  Usage of RUNPATH tags is not too common, so disabling this feature 
	  should be safe for most people.

config UCLIBC_CTOR_DTOR
	bool "Support global constructors and destructors"
	default y
	help
	  If you wish to build uClibc with support for global constructor
	  (ctor) and global destructor (dtor) support, then answer Y here.
	  When ctor/dtor support is enabled, binaries linked with uClibc must
	  also be linked with crtbegin.o and crtend.o which are provided by gcc
	  (the "*startfile:" and "*endfile:" settings in your gcc specs file
	  may need to be adjusted to include these files).  This support will
	  also add a small amount of additional size to each binary compiled vs
	  uClibc.  If you will be using uClibc with C++, or if you need the gcc
	  __attribute__((constructor)) and __attribute__((destructor)) to work,
	  then you definitely want to answer Y here.  If you don't need ctors
	  or dtors and want your binaries to be as small as possible, then
	  answer N.

config HAS_NO_THREADS
	bool
	default n

config UCLIBC_HAS_THREADS
	bool "POSIX Threading Support"
	depends on !HAS_NO_THREADS
	default y
	help
	  If you want to compile uClibc with pthread support, then answer Y.
	  This will increase the size of uClibc by adding a bunch of locking
	  to critical data structures, and adding extra code to ensure that
	  functions are properly reentrant.

	  If your applications require pthreads, answer Y.

config PTHREADS_DEBUG_SUPPORT
	bool "Build pthreads debugging support"
	default n
	depends on UCLIBC_HAS_THREADS
	help
	  Say Y here if you wish to be able to debug applications that use
	  uClibc's pthreads library.  By enabling this option, a library
	  named libthread_db will be built.  This library will be dlopen()'d
	  by gdb and will allow gdb to debug the threads in your application.

	  IMPORTANT NOTE!  Because gdb must dlopen() the libthread_db library,
	  you must compile gdb with uClibc in order for pthread debugging to
	  work properly.

	  If you are doing development and want to debug applications using
	  uClibc's pthread library, answer Y.  Otherwise, answer N.

config LINUXTHREADS_OLD
	bool "Use the older (stable) version of linuxthreads"
	default y
	depends on UCLIBC_HAS_THREADS
	help
	  There are two versions of linuxthreads.  The older (stable) version
	  has been in uClibc for quite a long time but hasn't seen too many
	  updates other than bugfixes.

	  The new version has not been tested much, and lacks ports for arches
	  which glibc does not support (like bfin/frv/etc...), but is based on
	  the latest code from glibc, so it may be the only choice for the
	  newer ports (like alpha/amd64/64bit arches and hppa).

config UCLIBC_HAS_LFS
	bool "Large File Support"
	default y
	help
	  If you wish to build uClibc with support for accessing large files
	  (i.e. files greater then 2 GiB) then answer Y.  Do not enable this
	  if you are using an older Linux kernel (2.0.x) that lacks large file
	  support.  Enabling this option will increase the size of uClibc.

choice
	prompt "Malloc Implementation"
	default MALLOC if ! ARCH_USE_MMU
	default MALLOC_STANDARD if ARCH_USE_MMU
	help
	  "malloc" use mmap for all allocations and so works very well on MMU-less
	  systems that do not support the brk() system call.   It is pretty smart
	  about reusing already allocated memory, and minimizing memory wastage.
	  This is the default for uClinux MMU-less systems.

	  "malloc-simple" was written from scratch for uClibc, and is the
	  simplest possible (and therefore smallest) malloc implementation.
	  This uses only the mmap() system call to allocation memory, and does
	  not use the brk() system call at all, making it a fine choice for
	  MMU-less systems with very limited memory.  It is rather dumb, and
	  certainly isn't the fastest.  But it is 100% standards compliant,
	  thread safe, and very small.

	  "malloc-standard" is derived from the public domain dlmalloc
	  implementation by Doug Lea.  It is quite fast, and is pretty smart
	  about reusing already allocated memory, and minimizing memory
	  wastage.  This uses brk() for small allocations, while using mmap()
	  for larger allocations.  This is the default malloc implementation
	  for uClibc.

	  If unsure, answer "malloc-standard".

config MALLOC_GLIBC_COMPAT
	bool "Malloc returns live pointer for malloc(0)"
	default n
	help
	  The behavior of malloc(0) is listed as implementation-defined by
	  SuSv3.  Glibc returns a valid pointer to something, while uClibc
	  normally return a NULL.  I personally feel glibc's behavior is
	  not particularly safe, and allows buggy applications to hide very
	  serious problems.

	  When this option is enabled, uClibc will act just like glibc, and
	  return a live pointer when someone calls malloc(0).  This pointer
	  provides a malloc'ed area with a size of 1 byte.  This feature is
	  mostly useful when dealing with applications using autoconf's broken
	  AC_FUNC_MALLOC macro (which  redefines malloc as rpl_malloc if it
	  does not detect glibc style returning-a-valid-pointer-for-malloc(0)
	  behavior).  Most people can safely answer N.

config UCLIBC_DYNAMIC_ATEXIT
	bool "Dynamic atexit() Support"
	default y
	help
	  When this option is enabled, uClibc will support an infinite number,
	  of atexit() and on_exit() functions, limited only by your available
	  memory.  This can be important when uClibc is used with C++, since
	  global destructors are implemented via atexit(), and it is quite
	  possible to exceed the default number when this option is disabled.
	  Enabling this option adds a few bytes, and more significantly makes
	  atexit and on_exit depend on malloc, which can be bad when compiling
	  static executables.

	  Unless you use uClibc with C++, you should probably answer N.

config COMPAT_ATEXIT
	bool "Old (visible) atexit Support"
	default n
	help
	  Enable this option if you want to update from 0.9.28 to svn/0.9.29, else
	  you will be missing atexit() until you rebuild all apps.

config UCLIBC_SUSV3_LEGACY
	bool "Enable SuSv3 LEGACY functions"
	default n
	help
	  Enable this option if you want to have SuSv3 LEGACY functions
	  in the library, else they are replaced by SuSv3 proposed macros.
	  Currently applies to bcopy/bzero/bcmp/index/rindex.
	  WARNING! ABI incompatibility.

config HAS_SHADOW
	bool "Shadow Password Support"
	default y
	help
	  Answer N if you do not need shadow password support.
	  Most people will answer Y.

config UCLIBC_HAS_PROGRAM_INVOCATION_NAME
	bool "Support for program_invocation_name"
	default n
	help
	  Support for 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.

	  At startup, these external strings are automatically set
	  up based on the value of ARGV[0].

	  If unsure, just answer N.

config UCLIBC_HAS___PROGNAME
	bool "Support for __progname"
	default y
	help
	  Some packages (like openssh) like to peek into internal libc
	  symbols to make their output a bit more user friendly.

	  At startup, __progname is automatically set up based on the
	  value of ARGV[0].

	  If unsure, just answer N.

config UNIX98PTY_ONLY
	bool "Support only Unix 98 PTYs"
	default y
	help
	  If you want to support only Unix 98 PTYs enable this.  Some older
	  applications may need this disabled.  For most current programs,
	  you can generally answer Y.

config ASSUME_DEVPTS
	bool "Assume that /dev/pts is a devpts or devfs file system"
	default y
	help
	  Enable this if /dev/pts is on a devpts or devfs filesystem.  Both
	  these filesystems automatically manage permissions on the /dev/pts
	  devices.  You may need to mount your devpts or devfs filesystem on
	  /dev/pts for this to work.

	  Most people should answer Y.

config UCLIBC_HAS_TM_EXTENSIONS
	bool "Support 'struct tm' timezone extension fields"
	default y
	help
	  Enabling this option adds fields to 'struct tm' in time.h for
	  tracking the number of seconds east of UTC, and an abbreviation for
	  the current timezone.  These fields are not specified by the SuSv3
	  standard, but they are commonly used in both GNU and BSD application
	  code.

	  To strictly follow the SuSv3 standard, leave this disabled.
	  Most people will probably want to answer Y.

config UCLIBC_HAS_TZ_CACHING
	bool "Enable caching of the last valid timezone 'TZ' string"
	default y
	help
	  Answer Y to enable caching of the last valid 'TZ' string describing
	  the timezone setting.  This allows a quick string compare to avoid
	  repeated parsing of unchanged 'TZ' strings when tzset() is called.

	  Most people will answer Y.

config UCLIBC_HAS_TZ_FILE
	bool "Enable '/etc/TZ' file support to set a default timezone (uClibc-specific)"
	default y
	help
	  Answer Y to enable the setting of a default timezone for uClibc.

	  Ordinarily, uClibc gets the timezone information exclusively from the
	  'TZ' environment variable.  In particular, there is no support for
	  the zoneinfo directory tree or the /etc/timezone file used by glibc.

	  With this option enabled, uClibc will use the value stored in the
	  file '/etc/TZ' (default path) to obtain timezone information if the
	  'TZ' environment variable is missing or has an invalid value.  The
	  file consists of a single line (newline required) of text describing
	  the timezone in the format specified for the TZ environment variable.

	  Simply doing 'echo CST6CDT > /etc/TZ' is enough to create a valid file.
	  See
	  http://www.opengroup.org/onlinepubs/007904975/basedefs/xbd_chap08.html
	  for details on valid settings of 'TZ'.

	  Most people will answer Y.

config UCLIBC_HAS_TZ_FILE_READ_MANY
	bool "Repeatedly read the '/etc/TZ' file"
	depends on UCLIBC_HAS_TZ_FILE
	default y
	help
	  Answer Y to enable repeated reading of the '/etc/TZ' file even after
	  a valid value has been read.  This incurs the overhead of an open/read/close
	  for each tzset() call (explicit or implied).  However, setting this
	  will allows applications to update their timezone information if the contents
	  of the file change.

	  Most people will answer Y.

config UCLIBC_TZ_FILE_PATH
	string "Path to the 'TZ' file for setting the global timezone"
	depends on UCLIBC_HAS_TZ_FILE
	default "/etc/TZ"
	help
	  This is the path to the 'TZ' file.
