2285 \`configure' configures libgnu UNUSED-VERSION to adapt to many kinds of systems.
2286
2287 Usage: $0 [OPTION]... [VAR=VALUE]...
2288
2289 To assign environment variables (e.g., CC, CFLAGS...), specify them as
2290 VAR=VALUE. See below for descriptions of some of the useful variables.
2291
2292 Defaults for the options are specified in brackets.
2293
2294 Configuration:
2295 -h, --help display this help and exit
2296 --help=short display options specific to this package
2297 --help=recursive display the short help of all the included packages
2298 -V, --version display version information and exit
2299 -q, --quiet, --silent do not print \`checking ...' messages
2300 --cache-file=FILE cache test results in FILE [disabled]
2301 -C, --config-cache alias for \`--cache-file=config.cache'
2302 -n, --no-create do not create output files
2303 --srcdir=DIR find the sources in DIR [configure dir or \`..']
2304
2305 Installation directories:
2306 --prefix=PREFIX install architecture-independent files in PREFIX
2307 [$ac_default_prefix]
2308 --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
2309 [PREFIX]
2310
2311 By default, \`make install' will install all the files in
2312 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
2313 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
2314 for instance \`--prefix=\$HOME'.
2315
2316 For better control, use the options below.
2317
2318 Fine tuning of the installation directories:
2319 --bindir=DIR user executables [EPREFIX/bin]
2320 --sbindir=DIR system admin executables [EPREFIX/sbin]
2321 --libexecdir=DIR program executables [EPREFIX/libexec]
2322 --sysconfdir=DIR read-only single-machine data [PREFIX/etc]
2323 --sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]
2324 --localstatedir=DIR modifiable single-machine data [PREFIX/var]
2325 --libdir=DIR object code libraries [EPREFIX/lib]
2326 --includedir=DIR C header files [PREFIX/include]
2327 --oldincludedir=DIR C header files for non-gcc [/usr/include]
2328 --datarootdir=DIR read-only arch.-independent data root [PREFIX/share]
2329 --datadir=DIR read-only architecture-independent data [DATAROOTDIR]
2330 --infodir=DIR info documentation [DATAROOTDIR/info]
2331 --localedir=DIR locale-dependent data [DATAROOTDIR/locale]
2332 --mandir=DIR man documentation [DATAROOTDIR/man]
2333 --docdir=DIR documentation root [DATAROOTDIR/doc/libgnu]
2334 --htmldir=DIR html documentation [DOCDIR]
2335 --dvidir=DIR dvi documentation [DOCDIR]
2336 --pdfdir=DIR pdf documentation [DOCDIR]
2337 --psdir=DIR ps documentation [DOCDIR]
2338 _ACEOF
2339
2340 cat <<\_ACEOF
2341
2342 Program names:
2343 --program-prefix=PREFIX prepend PREFIX to installed program names
2344 --program-suffix=SUFFIX append SUFFIX to installed program names
2345 --program-transform-name=PROGRAM run sed PROGRAM on installed program names
2346
2347 System types:
2348 --build=BUILD configure for building on BUILD [guessed]
2349 --host=HOST cross-compile to build programs to run on HOST [BUILD]
2350 --target=TARGET configure for building compilers for TARGET [HOST]

2360 Optional Features:
2361 --disable-option-checking ignore unrecognized --enable/--with options
2362 --disable-FEATURE do not include FEATURE (same as --enable-FEATURE=no)
2363 --enable-FEATURE[=ARG] include FEATURE [ARG=yes]
2364 --enable-maintainer-mode
2365 enable make rules and dependencies not useful (and
2366 sometimes confusing) to the casual installer
2367 --disable-largefile omit support for large files
2368 --enable-dependency-tracking
2369 do not reject slow dependency extractors
2370 --disable-dependency-tracking
2371 speeds up one-time build
2372 --enable-silent-rules less verbose build output (undo: "make V=1")
2373 --disable-silent-rules verbose build output (undo: "make V=0")
2374
2375 Some influential environment variables:
2376 CC C compiler command
2377 CFLAGS C compiler flags
2378 LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
2379 nonstandard directory <lib dir>
2380 LIBS libraries to pass to the linker, e.g. -l<library>
2381 CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
2382 you have headers in a nonstandard directory <include dir>
2383 CPP C preprocessor
2384
2385 Use these variables to override the choices made by `configure' or to help
2386 it to find libraries and programs with nonstandard names/locations.
2387
2388 Report bugs to the package provider.

25417 Oops!

25419 Your 'rm' program seems unable to run without file operands specified
25420 on the command line, even when the '-f' option is present. This is contrary
25421 to the behaviour of most rm programs out there, and not conforming with
25422 the upcoming POSIX standard: <http://austingroupbugs.net/view.php?id=542>
25423
25424 Please tell bug-automake@gnu.org about your system, including the value
25425 of your $PATH and any error possibly output before this message. This
25426 can help us improve future automake versions.
