785 Usage: $0 [OPTION]... [VAR=VALUE]...
786
787 To assign environment variables (e.g., CC, CFLAGS...), specify them as
788 VAR=VALUE. See below for descriptions of some of the useful variables.
789
790 Defaults for the options are specified in brackets.
791
792 Configuration:
793 -h, --help display this help and exit
794 --help=short display options specific to this package
795 --help=recursive display the short help of all the included packages
796 -V, --version display version information and exit
797 -q, --quiet, --silent do not print \`checking...' messages
798 --cache-file=FILE cache test results in FILE [disabled]
799 -C, --config-cache alias for \`--cache-file=config.cache'
800 -n, --no-create do not create output files
801 --srcdir=DIR find the sources in DIR [configure dir or \`..']

811
812 By default, \`make install' will install all the files in
813 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
814 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
815 for instance \`--prefix=\$HOME'.
816
817 For better control, use the options below.

819 Fine tuning of the installation directories:
820 --bindir=DIR user executables [EPREFIX/bin]
821 --sbindir=DIR system admin executables [EPREFIX/sbin]

860 Some influential environment variables:
861 CC C compiler command
862 CFLAGS C compiler flags
863 LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
864 nonstandard directory <lib dir>
865 CPPFLAGS C/C++ preprocessor flags, e.g. -I<include dir> if you have
866 headers in a nonstandard directory <include dir>
867 CPP C preprocessor
868
869 Use these variables to override the choices made by `configure' or to help
870 it to find libraries and programs with nonstandard names/locations.
