1458 \`configure' configures zfs 0.7.5 to adapt to many kinds of systems.
1459
1460 Usage: $0 [OPTION]... [VAR=VALUE]...
1461
1462 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1463 VAR=VALUE.  See below for descriptions of some of the useful variables.
1464
1465 Defaults for the options are specified in brackets.
1466
1467 Configuration:
1468   -h, --help              display this help and exit
1469       --help=short        display options specific to this package
1470       --help=recursive    display the short help of all the included packages
1471   -V, --version           display version information and exit
1472   -q, --quiet, --silent   do not print \`checking ...' messages
1473       --cache-file=FILE   cache test results in FILE [disabled]
1474   -C, --config-cache      alias for \`--cache-file=config.cache'
1475   -n, --no-create         do not create output files
1476       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1477
1478 Installation directories:
1479   --prefix=PREFIX         install architecture-independent files in PREFIX
1480                           [$ac_default_prefix]
1481   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1482                           [PREFIX]
1483
1484 By default, \`make install' will install all the files in
1485 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1486 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1487 for instance \`--prefix=\$HOME'.
1488
1489 For better control, use the options below.

1492   --bindir=DIR            user executables [EPREFIX/bin]

1597   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1598               nonstandard directory <lib dir>
1599   LIBS        libraries to pass to the linker, e.g. -l<library>
1600   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1601               you have headers in a nonstandard directory <include dir>
1602   LT_SYS_LIBRARY_PATH
1603               User-defined run-time library search path.
1604   CPP         C preprocessor

1606   CCASFLAGS   assembler compiler flags (defaults to CFLAGS)
1607
1608 Use these variables to override the choices made by `configure' or to help
1609 it to find libraries and programs with nonstandard names/locations.

3268
3269 Your 'rm' program seems unable to run without file operands specified
3270 on the command line, even when the '-f' option is present.  This is contrary
3271 to the behaviour of most rm programs out there, and not conforming with
3272 the upcoming POSIX standard: <http://austingroupbugs.net/view.php?id=542>
3273
3274 Please tell bug-automake@gnu.org about your system, including the value
3275 of your $PATH and any error possibly output before this message.  This
3276 can help us improve future automake versions.
