2772 \`configure' configures libgnu UNUSED-VERSION to adapt to many kinds of systems.
2773
2774 Usage: $0 [OPTION]... [VAR=VALUE]...
2775
2776 To assign environment variables (e.g., CC, CFLAGS...), specify them as
2777 VAR=VALUE. See below for descriptions of some of the useful variables.
2778
2779 Defaults for the options are specified in brackets.
2780
2781 Configuration:
2782 -h, --help display this help and exit
2783 --help=short display options specific to this package
2784 --help=recursive display the short help of all the included packages
2785 -V, --version display version information and exit
2786 -q, --quiet, --silent do not print \`checking ...' messages
2787 --cache-file=FILE cache test results in FILE [disabled]
2788 -C, --config-cache alias for \`--cache-file=config.cache'
2789 -n, --no-create do not create output files
2790 --srcdir=DIR find the sources in DIR [configure dir or \`..']
2791
2792 Installation directories:
2793 --prefix=PREFIX install architecture-independent files in PREFIX
2794 [$ac_default_prefix]
2795 --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
2796 [PREFIX]
2797
2798 By default, \`make install' will install all the files in
2799 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
2800 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
2801 for instance \`--prefix=\$HOME'.
2802
2803 For better control, use the options below.
2804
2805 Fine tuning of the installation directories:
2806 --bindir=DIR user executables [EPREFIX/bin]
2807 --sbindir=DIR system admin executables [EPREFIX/sbin]
2808 --libexecdir=DIR program executables [EPREFIX/libexec]
2809 --sysconfdir=DIR read-only single-machine data [PREFIX/etc]
2810 --sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]
2811 --localstatedir=DIR modifiable single-machine data [PREFIX/var]
2812 --libdir=DIR object code libraries [EPREFIX/lib]
2813 --includedir=DIR C header files [PREFIX/include]
2814 --oldincludedir=DIR C header files for non-gcc [/usr/include]
2815 --datarootdir=DIR read-only arch.-independent data root [PREFIX/share]

2829 Program names:
2830 --program-prefix=PREFIX prepend PREFIX to installed program names
2831 --program-suffix=SUFFIX append SUFFIX to installed program names
2832 --program-transform-name=PROGRAM run sed PROGRAM on installed program names
2833
2834 System types:
2835 --build=BUILD configure for building on BUILD [guessed]

2847 Optional Features:
2848 --disable-option-checking ignore unrecognized --enable/--with options
2849 --disable-FEATURE do not include FEATURE (same as --enable-FEATURE=no)
2850 --enable-FEATURE[=ARG] include FEATURE [ARG=yes]
2851 --enable-maintainer-mode
2852 enable make rules and dependencies not useful (and
2853 sometimes confusing) to the casual installer
2854 --enable-plugins Enable support for plugins
2855 --disable-largefile omit support for large files
2856 --disable-year2038 omit support for timestamps past the year 2038
2857 --enable-threads={isoc|posix|isoc+posix|windows}
2858 specify multithreading API
2859 --disable-threads build without multithread safety
2860 --enable-cross-guesses={conservative|risky}
2861 specify policy for cross-compilation guesses
2862 --enable-dependency-tracking
2863 do not reject slow dependency extractors
2864 --disable-dependency-tracking
2865 speeds up one-time build
2866 --enable-silent-rules less verbose build output (undo: "make V=1")
2867 --disable-silent-rules verbose build output (undo: "make V=0")
2868
2869 Some influential environment variables:
2870 CC C compiler command
2871 CFLAGS C compiler flags
2872 LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
2873 nonstandard directory <lib dir>
2874 LIBS libraries to pass to the linker, e.g. -l<library>
2875 CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
2876 you have headers in a nonstandard directory <include dir>
2877 CPP C preprocessor
2878
2879 Use these variables to override the choices made by `configure' or to help
2880 it to find libraries and programs with nonstandard names/locations.
