2343 \`configure' configures libgnu UNUSED-VERSION to adapt to many kinds of systems.
2344
2345 Usage: $0 [OPTION]... [VAR=VALUE]...
2346
2347 To assign environment variables (e.g., CC, CFLAGS...), specify them as
2348 VAR=VALUE. See below for descriptions of some of the useful variables.
2349
2350 Defaults for the options are specified in brackets.
2351
2352 Configuration:
2353 -h, --help display this help and exit
2354 --help=short display options specific to this package
2355 --help=recursive display the short help of all the included packages
2356 -V, --version display version information and exit
2357 -q, --quiet, --silent do not print \`checking ...' messages
2358 --cache-file=FILE cache test results in FILE [disabled]
2359 -C, --config-cache alias for \`--cache-file=config.cache'
2360 -n, --no-create do not create output files
2361 --srcdir=DIR find the sources in DIR [configure dir or \`..']
2362
2363 Installation directories:
2364 --prefix=PREFIX install architecture-independent files in PREFIX
2365 [$ac_default_prefix]
2366 --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
2367 [PREFIX]
2368
2369 By default, \`make install' will install all the files in
2370 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
2371 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
2372 for instance \`--prefix=\$HOME'.
2373
2374 For better control, use the options below.
2375
2376 Fine tuning of the installation directories:
2377 --bindir=DIR user executables [EPREFIX/bin]
2378 --sbindir=DIR system admin executables [EPREFIX/sbin]
2379 --libexecdir=DIR program executables [EPREFIX/libexec]
2380 --sysconfdir=DIR read-only single-machine data [PREFIX/etc]
2381 --sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]
2382 --localstatedir=DIR modifiable single-machine data [PREFIX/var]
2383 --libdir=DIR object code libraries [EPREFIX/lib]
2384 --includedir=DIR C header files [PREFIX/include]
2385 --oldincludedir=DIR C header files for non-gcc [/usr/include]
2386 --datarootdir=DIR read-only arch.-independent data root [PREFIX/share]
2387 --datadir=DIR read-only architecture-independent data [DATAROOTDIR]
2388 --infodir=DIR info documentation [DATAROOTDIR/info]

2402 --program-suffix=SUFFIX append SUFFIX to installed program names
2403 --program-transform-name=PROGRAM run sed PROGRAM on installed program names
2404
2405 System types:
2406 --build=BUILD configure for building on BUILD [guessed]

2418 Optional Features:
2419 --disable-option-checking ignore unrecognized --enable/--with options
2420 --disable-FEATURE do not include FEATURE (same as --enable-FEATURE=no)
2421 --enable-FEATURE[=ARG] include FEATURE [ARG=yes]
2422 --enable-maintainer-mode
2423 enable make rules and dependencies not useful (and
2424 sometimes confusing) to the casual installer
2425 --disable-largefile omit support for large files
2426 --enable-threads={posix|solaris|pth|windows}
2427 specify multithreading API
2428 --disable-threads build without multithread safety
2429 --enable-plugins Enable support for plugins
2430 --disable-rpath do not hardcode runtime library paths
2431 --enable-dependency-tracking
2432 do not reject slow dependency extractors
2433 --disable-dependency-tracking
2434 speeds up one-time build
2435 --enable-silent-rules less verbose build output (undo: "make V=1")
2436 --disable-silent-rules verbose build output (undo: "make V=0")
2437
2438 Optional Packages:
2439 --with-PACKAGE[=ARG] use PACKAGE [ARG=yes]
2440 --without-PACKAGE do not use PACKAGE (same as --with-PACKAGE=no)
2441 --with-gnu-ld assume the C compiler uses GNU ld [default=no]
2442 --with-libpth-prefix[=DIR] search for libpth in DIR/include and DIR/lib
2443 --without-libpth-prefix don't search for libpth in includedir and libdir
2444
2445 Some influential environment variables:
2446 CC C compiler command
2447 CFLAGS C compiler flags
2448 LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
2449 nonstandard directory <lib dir>
2450 LIBS libraries to pass to the linker, e.g. -l<library>
2451 CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
2452 you have headers in a nonstandard directory <include dir>
2453 CPP C preprocessor
2454
2455 Use these variables to override the choices made by `configure' or to help
2456 it to find libraries and programs with nonstandard names/locations.
2457
2458 Report bugs to the package provider.
