2330 \`configure' configures libgnu UNUSED-VERSION to adapt to many kinds of systems.
2331
2332 Usage: $0 [OPTION]... [VAR=VALUE]...
2333
2334 To assign environment variables (e.g., CC, CFLAGS...), specify them as
2335 VAR=VALUE. See below for descriptions of some of the useful variables.
2336
2337 Defaults for the options are specified in brackets.
2338
2339 Configuration:
2340 -h, --help display this help and exit
2341 --help=short display options specific to this package
2342 --help=recursive display the short help of all the included packages
2343 -V, --version display version information and exit
2344 -q, --quiet, --silent do not print \`checking ...' messages
2345 --cache-file=FILE cache test results in FILE [disabled]
2346 -C, --config-cache alias for \`--cache-file=config.cache'
2347 -n, --no-create do not create output files
2348 --srcdir=DIR find the sources in DIR [configure dir or \`..']
2349
2350 Installation directories:
2351 --prefix=PREFIX install architecture-independent files in PREFIX
2352 [$ac_default_prefix]
2353 --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
2354 [PREFIX]
2355
2356 By default, \`make install' will install all the files in
2357 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
2358 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
2359 for instance \`--prefix=\$HOME'.
2360
2361 For better control, use the options below.
2362
2363 Fine tuning of the installation directories:
2364 --bindir=DIR user executables [EPREFIX/bin]
2365 --sbindir=DIR system admin executables [EPREFIX/sbin]
2366 --libexecdir=DIR program executables [EPREFIX/libexec]
2367 --sysconfdir=DIR read-only single-machine data [PREFIX/etc]
2368 --sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]
2369 --localstatedir=DIR modifiable single-machine data [PREFIX/var]
2370 --libdir=DIR object code libraries [EPREFIX/lib]
2371 --includedir=DIR C header files [PREFIX/include]
2372 --oldincludedir=DIR C header files for non-gcc [/usr/include]
2373 --datarootdir=DIR read-only arch.-independent data root [PREFIX/share]
2374 --datadir=DIR read-only architecture-independent data [DATAROOTDIR]
2375 --infodir=DIR info documentation [DATAROOTDIR/info]

2387 Program names:
2388 --program-prefix=PREFIX prepend PREFIX to installed program names
2389 --program-suffix=SUFFIX append SUFFIX to installed program names
2390 --program-transform-name=PROGRAM run sed PROGRAM on installed program names
2391
2392 System types:
2393 --build=BUILD configure for building on BUILD [guessed]

2405 Optional Features:
2406 --disable-option-checking ignore unrecognized --enable/--with options
2407 --disable-FEATURE do not include FEATURE (same as --enable-FEATURE=no)
2408 --enable-FEATURE[=ARG] include FEATURE [ARG=yes]
2409 --enable-maintainer-mode
2410 enable make rules and dependencies not useful (and
2411 sometimes confusing) to the casual installer
2412 --disable-largefile omit support for large files
2413 --enable-dependency-tracking
2414 do not reject slow dependency extractors
2415 --disable-dependency-tracking
2416 speeds up one-time build
2417 --enable-silent-rules less verbose build output (undo: "make V=1")
2418 --disable-silent-rules verbose build output (undo: "make V=0")
2419
2420 Some influential environment variables:
2421 CC C compiler command
2422 CFLAGS C compiler flags
2423 LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
2424 nonstandard directory <lib dir>
2425 LIBS libraries to pass to the linker, e.g. -l<library>
2426 CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
2427 you have headers in a nonstandard directory <include dir>
2428 CPP C preprocessor
2429
2430 Use these variables to override the choices made by `configure' or to help
2431 it to find libraries and programs with nonstandard names/locations.
2432
2433 Report bugs to the package provider.

26766 Oops!
26767
26768 Your 'rm' program seems unable to run without file operands specified
26769 on the command line, even when the '-f' option is present. This is contrary
26770 to the behaviour of most rm programs out there, and not conforming with
26771 the upcoming POSIX standard: <http://austingroupbugs.net/view.php?id=542>
26772
26773 Please tell bug-automake@gnu.org about your system, including the value
26774 of your $PATH and any error possibly output before this message. This
26775 can help us improve future automake versions.

26785
26786 You can download and install GNU coreutils to get an 'rm' implementation
26787 that behaves properly: <http://www.gnu.org/software/coreutils/>.

26789 If you want to complete the configuration process using your problematic
26790 'rm' anyway, export the environment variable ACCEPT_INFERIOR_RM_PROGRAM
26791 to "yes", and re-run configure.
