2331 \`configure' configures libgnu UNUSED-VERSION to adapt to many kinds of systems.
2332
2333 Usage: $0 [OPTION]... [VAR=VALUE]...
2334
2335 To assign environment variables (e.g., CC, CFLAGS...), specify them as
2336 VAR=VALUE. See below for descriptions of some of the useful variables.
2337
2338 Defaults for the options are specified in brackets.
2339
2340 Configuration:
2341 -h, --help display this help and exit
2342 --help=short display options specific to this package
2343 --help=recursive display the short help of all the included packages
2344 -V, --version display version information and exit
2345 -q, --quiet, --silent do not print \`checking ...' messages
2346 --cache-file=FILE cache test results in FILE [disabled]
2347 -C, --config-cache alias for \`--cache-file=config.cache'
2348 -n, --no-create do not create output files
2349 --srcdir=DIR find the sources in DIR [configure dir or \`..']
2350
2351 Installation directories:
2352 --prefix=PREFIX install architecture-independent files in PREFIX
2353 [$ac_default_prefix]
2354 --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
2355 [PREFIX]
2356
2357 By default, \`make install' will install all the files in
2358 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
2359 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
2360 for instance \`--prefix=\$HOME'.
2361
2362 For better control, use the options below.
2363
2364 Fine tuning of the installation directories:
2365 --bindir=DIR user executables [EPREFIX/bin]
2366 --sbindir=DIR system admin executables [EPREFIX/sbin]
2367 --libexecdir=DIR program executables [EPREFIX/libexec]
2368 --sysconfdir=DIR read-only single-machine data [PREFIX/etc]
2369 --sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]
2370 --localstatedir=DIR modifiable single-machine data [PREFIX/var]
2371 --libdir=DIR object code libraries [EPREFIX/lib]
2372 --includedir=DIR C header files [PREFIX/include]
2373 --oldincludedir=DIR C header files for non-gcc [/usr/include]
2374 --datarootdir=DIR read-only arch.-independent data root [PREFIX/share]
2375 --datadir=DIR read-only architecture-independent data [DATAROOTDIR]

2388 Program names:
2389 --program-prefix=PREFIX prepend PREFIX to installed program names
2390 --program-suffix=SUFFIX append SUFFIX to installed program names
2391 --program-transform-name=PROGRAM run sed PROGRAM on installed program names
2392
2393 System types:
2394 --build=BUILD configure for building on BUILD [guessed]

2406 Optional Features:
2407 --disable-option-checking ignore unrecognized --enable/--with options
2408 --disable-FEATURE do not include FEATURE (same as --enable-FEATURE=no)
2409 --enable-FEATURE[=ARG] include FEATURE [ARG=yes]
2410 --enable-maintainer-mode
2411 enable make rules and dependencies not useful (and
2412 sometimes confusing) to the casual installer
2413 --disable-largefile omit support for large files
2414 --enable-plugins Enable support for plugins
2415 --enable-dependency-tracking
2416 do not reject slow dependency extractors
2417 --disable-dependency-tracking
2418 speeds up one-time build
2419 --enable-silent-rules less verbose build output (undo: "make V=1")
2420 --disable-silent-rules verbose build output (undo: "make V=0")
2421
2422 Some influential environment variables:
2423 CC C compiler command
2424 CFLAGS C compiler flags
2425 LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
2426 nonstandard directory <lib dir>
2427 LIBS libraries to pass to the linker, e.g. -l<library>
2428 CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
2429 you have headers in a nonstandard directory <include dir>
2430 CPP C preprocessor
2431
2432 Use these variables to override the choices made by `configure' or to help
2433 it to find libraries and programs with nonstandard names/locations.
2434
2435 Report bugs to the package provider.
