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.

25291 Oops!
25292
25293 Your 'rm' program seems unable to run without file operands specified
25294 on the command line, even when the '-f' option is present. This is contrary
25295 to the behaviour of most rm programs out there, and not conforming with
25296 the upcoming POSIX standard: <http://austingroupbugs.net/view.php?id=542>
25297
25298 Please tell bug-automake@gnu.org about your system, including the value
25299 of your $PATH and any error possibly output before this message. This
25300 can help us improve future automake versions.
