1298 \`configure' configures tcpdump 5.0.0-PRE-GIT to adapt to many kinds of systems.
1299
1300 Usage: $0 [OPTION]... [VAR=VALUE]...
1301
1302 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1303 VAR=VALUE.  See below for descriptions of some of the useful variables.
1304
1305 Defaults for the options are specified in brackets.
1306
1307 Configuration:
1308   -h, --help              display this help and exit
1309       --help=short        display options specific to this package
1310       --help=recursive    display the short help of all the included packages
1311   -V, --version           display version information and exit
1312   -q, --quiet, --silent   do not print \`checking ...' messages
1313       --cache-file=FILE   cache test results in FILE [disabled]
1314   -C, --config-cache      alias for \`--cache-file=config.cache'
1315   -n, --no-create         do not create output files
1316       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1317
1318 Installation directories:
1319   --prefix=PREFIX         install architecture-independent files in PREFIX
1320                           [$ac_default_prefix]
1321   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1322                           [PREFIX]
1323
1324 By default, \`make install' will install all the files in
1325 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1326 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1327 for instance \`--prefix=\$HOME'.
1328
1329 For better control, use the options below.

1379 Optional Packages:
1380   --with-PACKAGE[=ARG]    use PACKAGE [ARG=yes]
1381   --without-PACKAGE       do not use PACKAGE (same as --with-PACKAGE=no)
1382   --without-gcc           don't use gcc
1383   --with-smi              link with libsmi (allows to load MIBs on the fly to
1384                           decode SNMP packets) [default=yes, if available]
1385   --with-user=USERNAME    drop privileges by default to USERNAME
1386   --with-chroot=DIRECTORY when dropping privileges, chroot to DIRECTORY
1387   --with-sandbox-capsicum use Capsicum security functions [default=yes, if
1388                           available]
1389   --with-crypto[=DIR]     use OpenSSL/libressl libcrypto (located in directory

1392
1393 Some influential environment variables:
1394   CC          C compiler command
1395   CFLAGS      C compiler flags
1396   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1397               nonstandard directory <lib dir>
1398   LIBS        libraries to pass to the linker, e.g. -l<library>
1399   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1400               you have headers in a nonstandard directory <include dir>
1401   CPP         C preprocessor
1402
1403 Use these variables to override the choices made by `configure' or to help
1404 it to find libraries and programs with nonstandard names/locations.
