Its website boasts that "nearly all known and -+useful functions from any other C library are available." This -+exhaustive approach has been one of GLIBC's strengths on desktop and -+server systems, but it has also given GLIBC a large footprint, both in -+memory and on disk, making it a challenge to use in embedded systems -+with limited resources. -+ -+The Embedded GNU C library (EGLIBC) is a variant of the GNU C library -+designed to work well on embedded systems. In particular, EGLIBC's -+component configuration system allows embedded developers to build -+customized versions of the library that include only the features -+their application uses, reducing its space requirements. -+ -+EGLIBC's component configuration system categorizes the library's -+functions into "option groups", and allows you to include or exclude -+option groups individually. Some option groups depend on others; -+EGLIBC tracks these relationships, and ensures that the selected -+configuration yields a functioning library. -+ -+ -+Consistent and Predictable Behavior -+ -+A flexible configuration system is a mixed blessing: if the options -+offered are poorly designed, it can be hard to see which choices will -+have the desired effects, and choices with obscure consequences can -+make debugging difficult. EGLIBC's configuration follows some general -+principles to reduce these risks: -+ -+- EGLIBC has a single default configuration for each target -+ architecture. -+ -+- In the default configuration, all option groups are enabled, and -+ EGLIBC is upwardly API- and ABI-compatible with GLIBC. -+ -+- As much as possible, configurations only affect what functions are -+ present, not how they behave. If the system works with an option -+ group disabled, it will still work with it enabled. -+ -+- As much as possible, configurations only select option groups --- -+ they do not describe characteristics of the target architecture. -+ -+These rules mean that you have a simple debugging strategy available -+if you suspect that your EGLIBC configuration might be the source of a -+problem: fall back to the default configuration, re-test, and then -+disable option groups one by one, until the problem reappears. -+ -+ -+The Option Groups -+ -+To see the current full list of implemented option groups, refer to the -+file 'option-groups.def' at the top of the source tree, or run -+'make menuconfig' from the top-level build directory. -+ -+The POSIX.1-2001 specification includes a suggested partition of all -+the functions in the POSIX C API into option groups: math functions -+like 'sin' and 'cos'; networking functions like 'socket' and -+'connect'; and so on. EGLIBC could use this partitioning as the basis -+for future option groups. -+ -+ -+Implementation -+ -+The EGLIBC component configuration system resembles the approach used -+by the Linux kernel to select device drivers, network protocols, and -+other features. A file named 'option-groups.config' in the top-level -+build directory contains assignments to Make variables, each of which -+enables or disables a particular option group. If the variable's -+value is set to 'y', then the option group is enabled; if it set to -+anything else, the option group is omitted. The file -+'option-groups.defaults', at the top of the source tree, establishes -+default values for all variables; all option groups are enabled by -+default. -+ -+For example, the following 'option-groups.config' would omit locale -+data, but include mathematical functions, and everything else: -+ -+ OPTION_EGLIBC_LOCALES = n -+ OPTION_EGLIBC_LIBM = y -+ -+Like the Linux kernel, EGLIBC supports a similar set of '*config' make -+targets to make it easier to create 'option-groups.config', with all -+dependencies between option groups automatically satisfied. Run -+'make help' to see the list of supported make config targets. For -+example, 'make menuconfig' will update the current config utilising a -+menu based program. -+ -+The option group names and their type (boolean, int, hex, string), help -+description, and dependencies with other option groups, are described by -+'option-groups.def' at the top of the source tree, analogous to the -+'Kconfig' files in the Linux kernel. -+ -+In general, each option group variable controls whether a given set of -+object files in EGLIBC is compiled and included in the final -+libraries, or omitted from the build. -+ -+Each subdirectory's Makefile categorizes its routines, libraries, and -+executables by option group. For example, EGLIBC's 'math/Makefile' -+places the 'libm' library in the OPTION_EGLIBC_LIBM group as follows: -+ -+ extra-libs-$(OPTION_EGLIBC_LIBM) := libm -+ -+Finally, common code in 'Makerules' cites the value of the variable -+'extra-libs-y', selecting only those libraries that belong to enabled -+option groups to be built. -+ -+ -+Current Status and Future Directions -+ -+The EGLIBC component configuration system described here is still -+under development. -+ -+We have used the system to subset some portions of EGLIBC's -+Index: libc/configure.ac -diff --git a/Makefile b/Makefile -index 658ccfa..f906391 100644 ---- a/Makefile -+++ b/Makefile -@@ -24,6 +24,7 @@ endif - - include Makeconfig - -+include options-config/Makefile - - # This is the default target; it makes everything except the tests. - .PHONY: all -diff --git a/config.make.in b/config.make.in -index a9f5696..294f8d1 100644 ---- a/config.make.in -+++ b/config.make.in -@@ -47,6 +47,8 @@ c++-sysincludes = @CXX_SYSINCLUDES@ - all-warnings = @all_warnings@ - enable-werror = @enable_werror@ - -+kconfig_tools = @KCONFIG_TOOLS@ -+ - have-z-combreloc = @libc_cv_z_combreloc@ - have-z-execstack = @libc_cv_z_execstack@ - have-Bgroup = @libc_cv_Bgroup@ -diff --git a/configure b/configure -index 7d7299a..4116404 100755 ---- a/configure -+++ b/configure -@@ -641,6 +641,7 @@ INSTALL_INFO - PERL - BASH_SHELL - libc_cv_gcc_static_libgcc -+KCONFIG_TOOLS - CXX_SYSINCLUDES - SYSINCLUDES - AUTOCONF -@@ -755,6 +756,7 @@ with_fp - with_binutils - with_selinux - with_headers -+with_kconfig - with_default_link - enable_sanity_checks - enable_shared -@@ -1459,6 +1461,9 @@ Optional Packages: - --with-selinux if building with SELinux support - --with-headers=PATH location of system headers to use (for example - /usr/src/linux/include) [default=compiler default] -+ --with-kconfig=PATH location of kconfig tools to use (from Linux kernel -+ builds) to re-use for configuring EGLIBC option -+ groups - --with-default-link do not use explicit linker scripts - --with-cpu=CPU select code for CPU variant - -@@ -3517,6 +3522,14 @@ fi - - - -+# Check whether --with-kconfig was given. -+if test "${with_kconfig+set}" = set; then -+ withval=$with_kconfig; KCONFIG_TOOLS=$withval -+else -+ KCONFIG_TOOLS='' -+fi -+ -+ - - # Check whether --with-default-link was given. - if test "${with_default_link+set}" = set; then : -diff --git a/configure.ac b/configure.ac -index a467a69..fc0ed4d 100644 ---- a/configure.ac -+++ b/configure.ac -@@ -136,6 +136,16 @@ AC_ARG_WITH([headers], - [sysheaders='']) - AC_SUBST(sysheaders) - -+AC_ARG_WITH([kconfig], -+ AC_HELP_STRING([--with-kconfig=PATH], -+ [location of kconfig tools to use (from Linux -+ kernel builds) to re-use for configuring EGLIBC -+ option groups]), -+ [KCONFIG_TOOLS=$withval], -+ [KCONFIG_TOOLS='']) -+AC_SUBST(KCONFIG_TOOLS) -+ -+ - AC_SUBST(use_default_link) - AC_ARG_WITH([default-link], - AC_HELP_STRING([--with-default-link], -diff --git a/option-groups.def b/option-groups.def -new file mode 100644 -index 0000000..6aebd94 ---- /dev/null -+++ b/option-groups.def -@@ -0,0 +1,868 @@ -+# This file documents the option groups EGLIBC currently supports, in -+# a format akin to the Linux Kconfig system's.
