1600 Usage: $0 [OPTION]... [VAR=VALUE]...
1602 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1603 VAR=VALUE. See below for descriptions of some of the useful variables.
1605 Defaults for the options are specified in brackets.
1607 Configuration:
1608 -h, --help display this help and exit
1609 --help=short display options specific to this package
1610 --help=recursive display the short help of all the included packages
1611 -V, --version display version information and exit
1612 -q, --quiet, --silent do not print \`checking ...' messages
1613 --cache-file=FILE cache test results in FILE [disabled]
1614 -C, --config-cache alias for \`--cache-file=config.cache'
1615 -n, --no-create do not create output files
1616 --srcdir=DIR find the sources in DIR [configure dir or \`..']
1618 Installation directories:
1619 --prefix=PREFIX install architecture-independent files in PREFIX
1620 [$ac_default_prefix]
1621 --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
1622 [PREFIX]
1624 By default, \`make install' will install all the files in
1625 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
1626 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1627 for instance \`--prefix=\$HOME'.
1629 For better control, use the options below.
