2223 \`configure' configures this package to adapt to many kinds of systems.
2224
2225 Usage: $0 [OPTION]... [VAR=VALUE]...
2226
2227 To assign environment variables (e.g., CC, CFLAGS...), specify them as
2228 VAR=VALUE.  See below for descriptions of some of the useful variables.
2229
2230 Defaults for the options are specified in brackets.
2231
2232 Configuration:
2233   -h, --help              display this help and exit
2234       --help=short        display options specific to this package
2235       --help=recursive    display the short help of all the included packages
2236   -V, --version           display version information and exit
2237   -q, --quiet, --silent   do not print \`checking...' messages
2238       --cache-file=FILE   cache test results in FILE [disabled]
2239   -C, --config-cache      alias for \`--cache-file=config.cache'
2240   -n, --no-create         do not create output files
2241       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
2242
2243 Installation directories:
2244   --prefix=PREFIX         install architecture-independent files in PREFIX
2245                           [$ac_default_prefix]
2246   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
2247                           [PREFIX]
2248
2249 By default, \`make install' will install all the files in
2250 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
2251 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
2252 for instance \`--prefix=\$HOME'.
2253
2254 For better control, use the options below.

2256 Fine tuning of the installation directories:
2257   --bindir=DIR            user executables [EPREFIX/bin]
2258   --sbindir=DIR           system admin executables [EPREFIX/sbin]

2264   --includedir=DIR        C header files [PREFIX/include]
2265   --oldincludedir=DIR     C header files for non-gcc [/usr/include]

2283   --program-transform-name=PROGRAM   run sed PROGRAM on installed program names
2284
2285 System types:
2286   --build=BUILD     configure for building on BUILD [guessed]
2287   --host=HOST       cross-compile to build programs to run on HOST [BUILD]
2288   --target=TARGET   configure for building compilers for TARGET [HOST]

2296 Optional Features:
2297   --disable-option-checking  ignore unrecognized --enable/--with options
2298   --disable-FEATURE       do not include FEATURE (same as --enable-FEATURE=no)
2299   --enable-FEATURE[=ARG]  include FEATURE [ARG=yes]
2300   --enable-maintainer-mode  enable make rules and dependencies not useful
2301                           (and sometimes confusing) to the casual installer
2302   --disable-largefile     omit support for large files
2303   --disable-dependency-tracking  speeds up one-time build
2304   --enable-dependency-tracking   do not reject slow dependency extractors
2305
2306 Some influential environment variables:
2307   CC          C compiler command
2308   CFLAGS      C compiler flags
2309   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
2310               nonstandard directory <lib dir>
2311   LIBS        libraries to pass to the linker, e.g. -l<library>
2312   CPPFLAGS    C/C++/Objective C preprocessor flags, e.g. -I<include dir> if
2313               you have headers in a nonstandard directory <include dir>
2314   CPP         C preprocessor
2315
2316 Use these variables to override the choices made by `configure' or to help
2317 it to find libraries and programs with nonstandard names/locations.
