1315 \`configure' configures DHCP 4.3.2rc2 to adapt to many kinds of systems.
1316
1317 Usage: $0 [OPTION]... [VAR=VALUE]...
1318
1319 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1320 VAR=VALUE.  See below for descriptions of some of the useful variables.
1321
1322 Defaults for the options are specified in brackets.
1323
1324 Configuration:
1325   -h, --help              display this help and exit
1326       --help=short        display options specific to this package
1327       --help=recursive    display the short help of all the included packages
1328   -V, --version           display version information and exit
1329   -q, --quiet, --silent   do not print \`checking ...' messages
1330       --cache-file=FILE   cache test results in FILE [disabled]
1331   -C, --config-cache      alias for \`--cache-file=config.cache'
1332   -n, --no-create         do not create output files
1333       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1334
1335 Installation directories:
1336   --prefix=PREFIX         install architecture-independent files in PREFIX
1337                           [$ac_default_prefix]
1338   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1339                           [PREFIX]
1340
1341 By default, \`make install' will install all the files in
1342 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1343 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1344 for instance \`--prefix=\$HOME'.
1345
1346 For better control, use the options below.

1461 Some influential environment variables:
1462   CC          C compiler command
1463   CFLAGS      C compiler flags
1464   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1465               nonstandard directory <lib dir>
1466   LIBS        libraries to pass to the linker, e.g. -l<library>
1467   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1468               you have headers in a nonstandard directory <include dir>
1469   CPP         C preprocessor
1470
1471 Use these variables to override the choices made by `configure' or to help
1472 it to find libraries and programs with nonstandard names/locations.
