 761 Usage: $0 [OPTION]... [VAR=VALUE]...
 762
 763 To assign environment variables (e.g., CC, CFLAGS...), specify them as
 764 VAR=VALUE.  See below for descriptions of some of the useful variables.
 765
 766 Defaults for the options are specified in brackets.
 767
 768 Configuration:
 769   -h, --help              display this help and exit
 770       --help=short        display options specific to this package
 771       --help=recursive    display the short help of all the included packages
 772   -V, --version           display version information and exit
 773   -q, --quiet, --silent   do not print \`checking...' messages
 774       --cache-file=FILE   cache test results in FILE [disabled]
 775   -C, --config-cache      alias for \`--cache-file=config.cache'
 776   -n, --no-create         do not create output files
 777       --srcdir=DIR        find the sources in DIR [configure dir or \`..']

 786                           [PREFIX]
 787
 788 By default, \`make install' will install all the files in
 789 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
 790 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
 791 for instance \`--prefix=\$HOME'.

 833 Some influential environment variables:
 834   CC          C compiler command
 835   CFLAGS      C compiler flags
 836   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
 837               nonstandard directory <lib dir>
 838   CPPFLAGS    C/C++ preprocessor flags, e.g. -I<include dir> if you have
 839               headers in a nonstandard directory <include dir>
 840
 841 Use these variables to override the choices made by `configure' or to help
 842 it to find libraries and programs with nonstandard names/locations.
