2581 Usage: $0 [OPTION]... [VAR=VALUE]...
2582
2583 To assign environment variables (e.g., CC, CFLAGS...), specify them as
2584 VAR=VALUE. See below for descriptions of some of the useful variables.
2585
2586 Defaults for the options are specified in brackets.
2587
2588 Configuration:
2589 -h, --help display this help and exit
2590 --help=short display options specific to this package
2591 --help=recursive display the short help of all the included packages
2592 -V, --version display version information and exit
2593 -q, --quiet, --silent do not print \`checking ...' messages
2594 --cache-file=FILE cache test results in FILE [disabled]
2595 -C, --config-cache alias for \`--cache-file=config.cache'
2596 -n, --no-create do not create output files
2597 --srcdir=DIR find the sources in DIR [configure dir or \`..']
2598
2599 Installation directories:
2600 --prefix=PREFIX install architecture-independent files in PREFIX
2601 [$ac_default_prefix]
2602 --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
2603 [PREFIX]
2604
2605 By default, \`make install' will install all the files in
2606 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
2607 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
2608 for instance \`--prefix=\$HOME'.
2609
2610 For better control, use the options below.

2657 --enable-FEATURE[=ARG] include FEATURE [ARG=yes]

2661 --enable-plugins Enable support for plugins
2662 --disable-largefile omit support for large files
2663 --enable-threads={isoc|posix|isoc+posix|windows}

2675 Some influential environment variables:
2676 CC C compiler command
2677 CFLAGS C compiler flags
2678 LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
2679 nonstandard directory <lib dir>
2680 LIBS libraries to pass to the linker, e.g. -l<library>
2681 CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
2682 you have headers in a nonstandard directory <include dir>
2683 CPP C preprocessor
2684
2685 Use these variables to override the choices made by `configure' or to help
2686 it to find libraries and programs with nonstandard names/locations.
2687
2688 Report bugs to the package provider.
