1239\`configure' configures ldns 1.7.0 to adapt to many kinds of systems.
1240
1241Usage: $0 [OPTION]... [VAR=VALUE]...
1242
1243To assign environment variables (e.g., CC, CFLAGS...), specify them as
1244VAR=VALUE.  See below for descriptions of some of the useful variables.
1245
1246Defaults for the options are specified in brackets.
1247
1248Configuration:
1249  -h, --help              display this help and exit
1250      --help=short        display options specific to this package
1251      --help=recursive    display the short help of all the included packages
1252  -V, --version           display version information and exit
1253  -q, --quiet, --silent   do not print \`checking ...' messages
1254      --cache-file=FILE   cache test results in FILE [disabled]
1255  -C, --config-cache      alias for \`--cache-file=config.cache'
1256  -n, --no-create         do not create output files
1257      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1258
1259Installation directories:
1260  --prefix=PREFIX         install architecture-independent files in PREFIX
1261                          [$ac_default_prefix]
1262  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1263                          [PREFIX]
1264
1265By default, \`make install' will install all the files in
1266\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1267an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1268for instance \`--prefix=\$HOME'.
1269
1270For better control, use the options below.

1323Some influential environment variables:
1324  CC          C compiler command
1325  CFLAGS      C compiler flags
1326  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1327              nonstandard directory <lib dir>
1328  LIBS        libraries to pass to the linker, e.g. -l<library>
1329  CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1330              you have headers in a nonstandard directory <include dir>
1331  CPP         C preprocessor
1332
1333Use these variables to override the choices made by `configure' or to help
1334it to find libraries and programs with nonstandard names/locations.
