2230 \`configure' configures this package to adapt to many kinds of systems.
2231
2232 Usage: $0 [OPTION]... [VAR=VALUE]...
2233
2234 To assign environment variables (e.g., CC, CFLAGS...), specify them as
2235 VAR=VALUE.  See below for descriptions of some of the useful variables.
2236
2237 Defaults for the options are specified in brackets.
2238
2239 Configuration:
2240   -h, --help              display this help and exit
2241       --help=short        display options specific to this package
2242       --help=recursive    display the short help of all the included packages
2243   -V, --version           display version information and exit
2244   -q, --quiet, --silent   do not print \`checking...' messages
2245       --cache-file=FILE   cache test results in FILE [disabled]
2246   -C, --config-cache      alias for \`--cache-file=config.cache'
2247   -n, --no-create         do not create output files
2248       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
2249
2250 Installation directories:
2251   --prefix=PREFIX         install architecture-independent files in PREFIX
2252                           [$ac_default_prefix]
2253   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
2254                           [PREFIX]
2255
2256 By default, \`make install' will install all the files in
2257 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
2258 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
2259 for instance \`--prefix=\$HOME'.
2260
2261 For better control, use the options below.

2263 Fine tuning of the installation directories:
2264   --bindir=DIR            user executables [EPREFIX/bin]
2265   --sbindir=DIR           system admin executables [EPREFIX/sbin]

2271   --includedir=DIR        C header files [PREFIX/include]
2272   --oldincludedir=DIR     C header files for non-gcc [/usr/include]

2290   --program-transform-name=PROGRAM   run sed PROGRAM on installed program names
2291
2292 System types:
2293   --build=BUILD     configure for building on BUILD [guessed]
2294   --host=HOST       cross-compile to build programs to run on HOST [BUILD]

2303 Optional Features:
2304   --disable-option-checking  ignore unrecognized --enable/--with options
2305   --disable-FEATURE       do not include FEATURE (same as --enable-FEATURE=no)
2306   --enable-FEATURE[=ARG]  include FEATURE [ARG=yes]
2307   --enable-maintainer-mode  enable make rules and dependencies not useful
2308                           (and sometimes confusing) to the casual installer
2309   --disable-largefile     omit support for large files
2310   --disable-dependency-tracking  speeds up one-time build
2311   --enable-dependency-tracking   do not reject slow dependency extractors
2312
2313 Some influential environment variables:
2314   CC          C compiler command
2315   CFLAGS      C compiler flags
2316   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
2317               nonstandard directory <lib dir>
2318   LIBS        libraries to pass to the linker, e.g. -l<library>
2319   CPPFLAGS    C/C++/Objective C preprocessor flags, e.g. -I<include dir> if
2320               you have headers in a nonstandard directory <include dir>
2321   CPP         C preprocessor
2322
2323 Use these variables to override the choices made by `configure' or to help
2324 it to find libraries and programs with nonstandard names/locations.
