1357 \`configure' configures pcap 1.10.4 to adapt to many kinds of systems.
1358
1359 Usage: $0 [OPTION]... [VAR=VALUE]...
1360
1361 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1362 VAR=VALUE.  See below for descriptions of some of the useful variables.
1363
1364 Defaults for the options are specified in brackets.
1365
1366 Configuration:
1367   -h, --help              display this help and exit
1368       --help=short        display options specific to this package
1369       --help=recursive    display the short help of all the included packages
1370   -V, --version           display version information and exit
1371   -q, --quiet, --silent   do not print \`checking ...' messages
1372       --cache-file=FILE   cache test results in FILE [disabled]
1373   -C, --config-cache      alias for \`--cache-file=config.cache'
1374   -n, --no-create         do not create output files
1375       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1376
1377 Installation directories:
1378   --prefix=PREFIX         install architecture-independent files in PREFIX
1379                           [$ac_default_prefix]
1380   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1381                           [PREFIX]
1382
1383 By default, \`make install' will install all the files in
1384 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1385 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1386 for instance \`--prefix=\$HOME'.
1387
1388 For better control, use the options below.
1389
1390 Fine tuning of the installation directories:
1391   --bindir=DIR            user executables [EPREFIX/bin]
1392   --sbindir=DIR           system admin executables [EPREFIX/sbin]
1393   --libexecdir=DIR        program executables [EPREFIX/libexec]
