792 \`configure' configures GNU C Library (see version.h) to adapt to many kinds of systems.
794 Usage: $0 [OPTION]... [VAR=VALUE]...
796 To assign environment variables (e.g., CC, CFLAGS...), specify them as
797 VAR=VALUE. See below for descriptions of some of the useful variables.
799 Defaults for the options are specified in brackets.
802 -h, --help display this help and exit
803 --help=short display options specific to this package
804 --help=recursive display the short help of all the included packages
805 -V, --version display version information and exit
806 -q, --quiet, --silent do not print \`checking...' messages
807 --cache-file=FILE cache test results in FILE [disabled]
808 -C, --config-cache alias for \`--cache-file=config.cache'
809 -n, --no-create do not create output files
810 --srcdir=DIR find the sources in DIR [configure dir or \`..']
815 Installation directories:
816 --prefix=PREFIX install architecture-independent files in PREFIX
818 --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
821 By default, \`make install' will install all the files in
822 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
823 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
824 for instance \`--prefix=\$HOME'.
826 For better control, use the options below.
828 Fine tuning of the installation directories:
829 --bindir=DIR user executables [EPREFIX/bin]
830 --sbindir=DIR system admin executables [EPREFIX/sbin]
831 --libexecdir=DIR program executables [EPREFIX/libexec]
832 --datadir=DIR read-only architecture-independent data [PREFIX/share]
833 --sysconfdir=DIR read-only single-machine data [PREFIX/etc]
834 --sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]
835 --localstatedir=DIR modifiable single-machine data [PREFIX/var]
836 --libdir=DIR object code libraries [EPREFIX/lib]
837 --includedir=DIR C header files [PREFIX/include]
838 --oldincludedir=DIR C header files for non-gcc [/usr/include]
839 --infodir=DIR info documentation [PREFIX/info]
840 --mandir=DIR man documentation [PREFIX/man]
846 --build=BUILD configure for building on BUILD [guessed]
847 --host=HOST cross-compile to build programs to run on HOST [BUILD]

898 --with-headers=PATH location of system headers to use (for example
899 /usr/src/linux/include) [default=compiler
901 --with-tls enable support for TLS
902 --without-__thread do not use TLS features even when supporting them
904 Some influential environment variables:
905 CC C compiler command
906 CFLAGS C compiler flags
907 LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
908 nonstandard directory <lib dir>
909 CPPFLAGS C/C++ preprocessor flags, e.g. -I<include dir> if you have
910 headers in a nonstandard directory <include dir>
912 CXX C++ compiler command
913 CXXFLAGS C++ compiler flags
915 Use these variables to override the choices made by `configure' or to help
916 it to find libraries and programs with nonstandard names/locations.
