2251 \`configure' configures this package to adapt to many kinds of systems.
2252
2253 Usage: $0 [OPTION]... [VAR=VALUE]...
2254
2255 To assign environment variables (e.g., CC, CFLAGS...), specify them as
2256 VAR=VALUE. See below for descriptions of some of the useful variables.
2257
2258 Defaults for the options are specified in brackets.
2259
2260 Configuration:
2261 -h, --help display this help and exit
2262 --help=short display options specific to this package
2263 --help=recursive display the short help of all the included packages
2264 -V, --version display version information and exit
2265 -q, --quiet, --silent do not print \`checking...' messages
2266 --cache-file=FILE cache test results in FILE [disabled]
2267 -C, --config-cache alias for \`--cache-file=config.cache'
2268 -n, --no-create do not create output files
2269 --srcdir=DIR find the sources in DIR [configure dir or \`..']
2270
2271 Installation directories:
2272 --prefix=PREFIX install architecture-independent files in PREFIX
2273 [$ac_default_prefix]
2274 --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
2275 [PREFIX]
2276
2277 By default, \`make install' will install all the files in
2278 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
2279 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
2280 for instance \`--prefix=\$HOME'.
2281
2282 For better control, use the options below.
2283
2284 Fine tuning of the installation directories:
2285 --bindir=DIR user executables [EPREFIX/bin]
2286 --sbindir=DIR system admin executables [EPREFIX/sbin]
2287 --libexecdir=DIR program executables [EPREFIX/libexec]
2288 --sysconfdir=DIR read-only single-machine data [PREFIX/etc]
2289 --sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]
2290 --localstatedir=DIR modifiable single-machine data [PREFIX/var]
2291 --libdir=DIR object code libraries [EPREFIX/lib]
2292 --includedir=DIR C header files [PREFIX/include]
2293 --oldincludedir=DIR C header files for non-gcc [/usr/include]
2294 --datarootdir=DIR read-only arch.-independent data root [PREFIX/share]
2295 --datadir=DIR read-only architecture-independent data [DATAROOTDIR]
2296 --infodir=DIR info documentation [DATAROOTDIR/info]
2297 --localedir=DIR locale-dependent data [DATAROOTDIR/locale]
2298 --mandir=DIR man documentation [DATAROOTDIR/man]
2299 --docdir=DIR documentation root [DATAROOTDIR/doc/PACKAGE]
2300 --htmldir=DIR html documentation [DOCDIR]
2301 --dvidir=DIR dvi documentation [DOCDIR]
2302 --pdfdir=DIR pdf documentation [DOCDIR]
2303 --psdir=DIR ps documentation [DOCDIR]
2304 _ACEOF
2305
2306 cat <<\_ACEOF
2307
2308 Program names:
2309 --program-prefix=PREFIX prepend PREFIX to installed program names
2310 --program-suffix=SUFFIX append SUFFIX to installed program names
2311 --program-transform-name=PROGRAM run sed PROGRAM on installed program names
2312
2313 System types:
2314 --build=BUILD configure for building on BUILD [guessed]
2315 --host=HOST cross-compile to build programs to run on HOST [BUILD]
2316 --target=TARGET configure for building compilers for TARGET [HOST]

2324 Optional Features:
2325 --disable-option-checking ignore unrecognized --enable/--with options
2326 --disable-FEATURE do not include FEATURE (same as --enable-FEATURE=no)
2327 --enable-FEATURE[=ARG] include FEATURE [ARG=yes]
2328 --enable-maintainer-mode enable make rules and dependencies not useful
2329 (and sometimes confusing) to the casual installer
2330 --disable-largefile omit support for large files
2331 --disable-dependency-tracking speeds up one-time build
2332 --enable-dependency-tracking do not reject slow dependency extractors
2333 --enable-silent-rules less verbose build output (undo: `make V=1')
2334 --disable-silent-rules verbose build output (undo: `make V=0')
2335
2336 Some influential environment variables:
2337 CC C compiler command
2338 CFLAGS C compiler flags
2339 LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
2340 nonstandard directory <lib dir>
2341 LIBS libraries to pass to the linker, e.g. -l<library>
2342 CPPFLAGS C/C++/Objective C preprocessor flags, e.g. -I<include dir> if
2343 you have headers in a nonstandard directory <include dir>
2344 CPP C preprocessor
2345
2346 Use these variables to override the choices made by `configure' or to help
2347 it to find libraries and programs with nonstandard names/locations.
