2248 \`configure' configures this package to adapt to many kinds of systems.
2249
2250 Usage: $0 [OPTION]... [VAR=VALUE]...
2251
2252 To assign environment variables (e.g., CC, CFLAGS...), specify them as
2253 VAR=VALUE. See below for descriptions of some of the useful variables.
2254
2255 Defaults for the options are specified in brackets.
2256
2257 Configuration:
2258 -h, --help display this help and exit
2259 --help=short display options specific to this package
2260 --help=recursive display the short help of all the included packages
2261 -V, --version display version information and exit
2262 -q, --quiet, --silent do not print \`checking...' messages
2263 --cache-file=FILE cache test results in FILE [disabled]
2264 -C, --config-cache alias for \`--cache-file=config.cache'
2265 -n, --no-create do not create output files
2266 --srcdir=DIR find the sources in DIR [configure dir or \`..']
2267
2268 Installation directories:
2269 --prefix=PREFIX install architecture-independent files in PREFIX
2270 [$ac_default_prefix]
2271 --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
2272 [PREFIX]
2273
2274 By default, \`make install' will install all the files in
2275 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
2276 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
2277 for instance \`--prefix=\$HOME'.
2278
2279 For better control, use the options below.
2280
2281 Fine tuning of the installation directories:
2282 --bindir=DIR user executables [EPREFIX/bin]
2283 --sbindir=DIR system admin executables [EPREFIX/sbin]
2284 --libexecdir=DIR program executables [EPREFIX/libexec]
2285 --sysconfdir=DIR read-only single-machine data [PREFIX/etc]
2286 --sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]
2287 --localstatedir=DIR modifiable single-machine data [PREFIX/var]
2288 --libdir=DIR object code libraries [EPREFIX/lib]
2289 --includedir=DIR C header files [PREFIX/include]
2290 --oldincludedir=DIR C header files for non-gcc [/usr/include]
2291 --datarootdir=DIR read-only arch.-independent data root [PREFIX/share]
2292 --datadir=DIR read-only architecture-independent data [DATAROOTDIR]
2293 --infodir=DIR info documentation [DATAROOTDIR/info]
2294 --localedir=DIR locale-dependent data [DATAROOTDIR/locale]
2295 --mandir=DIR man documentation [DATAROOTDIR/man]
2296 --docdir=DIR documentation root [DATAROOTDIR/doc/PACKAGE]
2297 --htmldir=DIR html documentation [DOCDIR]
2298 --dvidir=DIR dvi documentation [DOCDIR]
2299 --pdfdir=DIR pdf documentation [DOCDIR]
2300 --psdir=DIR ps documentation [DOCDIR]
2301 _ACEOF
2302
2303 cat <<\_ACEOF
2304
2305 Program names:
2306 --program-prefix=PREFIX prepend PREFIX to installed program names
2307 --program-suffix=SUFFIX append SUFFIX to installed program names
2308 --program-transform-name=PROGRAM run sed PROGRAM on installed program names
2309
2310 System types:
2311 --build=BUILD configure for building on BUILD [guessed]
2312 --host=HOST cross-compile to build programs to run on HOST [BUILD]
2313 --target=TARGET configure for building compilers for TARGET [HOST]

2321 Optional Features:
2322 --disable-option-checking ignore unrecognized --enable/--with options
2323 --disable-FEATURE do not include FEATURE (same as --enable-FEATURE=no)
2324 --enable-FEATURE[=ARG] include FEATURE [ARG=yes]
2325 --enable-maintainer-mode enable make rules and dependencies not useful
2326 (and sometimes confusing) to the casual installer
2327 --disable-largefile omit support for large files
2328 --disable-dependency-tracking speeds up one-time build
2329 --enable-dependency-tracking do not reject slow dependency extractors
2330
2331 Some influential environment variables:
2332 CC C compiler command
2333 CFLAGS C compiler flags
2334 LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
2335 nonstandard directory <lib dir>
2336 LIBS libraries to pass to the linker, e.g. -l<library>
2337 CPPFLAGS C/C++/Objective C preprocessor flags, e.g. -I<include dir> if
2338 you have headers in a nonstandard directory <include dir>
2339 CPP C preprocessor
2340
2341 Use these variables to override the choices made by `configure' or to help
2342 it to find libraries and programs with nonstandard names/locations.
