1271 \`configure' configures tcpdump 4.10.0-PRE-GIT to adapt to many kinds of systems.
1272
1273 Usage: $0 [OPTION]... [VAR=VALUE]...
1274
1275 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1276 VAR=VALUE.  See below for descriptions of some of the useful variables.
1277
1278 Defaults for the options are specified in brackets.
1279
1280 Configuration:
1281   -h, --help              display this help and exit
1282       --help=short        display options specific to this package
1283       --help=recursive    display the short help of all the included packages
1284   -V, --version           display version information and exit
1285   -q, --quiet, --silent   do not print \`checking ...' messages
1286       --cache-file=FILE   cache test results in FILE [disabled]
1287   -C, --config-cache      alias for \`--cache-file=config.cache'
1288   -n, --no-create         do not create output files
1289       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1290
1291 Installation directories:
1292   --prefix=PREFIX         install architecture-independent files in PREFIX
1293                           [$ac_default_prefix]
1294   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1295                           [PREFIX]
1296
1297 By default, \`make install' will install all the files in
1298 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1299 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1300 for instance \`--prefix=\$HOME'.
1301
1302 For better control, use the options below.

1355   --with-user=USERNAME    drop privileges by default to USERNAME
1356   --with-chroot=DIRECTORY when dropping privileges, chroot to DIRECTORY
1357   --with-sandbox-capsicum use Capsicum security functions [default=yes, if

1363
1364 Some influential environment variables:
1365   CC          C compiler command
1366   CFLAGS      C compiler flags
1367   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1368               nonstandard directory <lib dir>
1369   LIBS        libraries to pass to the linker, e.g. -l<library>
1370   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1371               you have headers in a nonstandard directory <include dir>
1372   CPP         C preprocessor
1373
1374 Use these variables to override the choices made by `configure' or to help
1375 it to find libraries and programs with nonstandard names/locations.
