1261 \`configure' configures tcpdump 4.10.0-PRE-GIT to adapt to many kinds of systems.
1262
1263 Usage: $0 [OPTION]... [VAR=VALUE]...
1264
1265 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1266 VAR=VALUE.  See below for descriptions of some of the useful variables.
1267
1268 Defaults for the options are specified in brackets.
1269
1270 Configuration:
1271   -h, --help              display this help and exit
1272       --help=short        display options specific to this package
1273       --help=recursive    display the short help of all the included packages
1274   -V, --version           display version information and exit
1275   -q, --quiet, --silent   do not print \`checking ...' messages
1276       --cache-file=FILE   cache test results in FILE [disabled]
1277   -C, --config-cache      alias for \`--cache-file=config.cache'
1278   -n, --no-create         do not create output files
1279       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1280
1281 Installation directories:
1282   --prefix=PREFIX         install architecture-independent files in PREFIX
1283                           [$ac_default_prefix]
1284   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1285                           [PREFIX]
1286
1287 By default, \`make install' will install all the files in
1288 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1289 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1290 for instance \`--prefix=\$HOME'.
1291
1292 For better control, use the options below.

1353 Some influential environment variables:
1354   CC          C compiler command
1355   CFLAGS      C compiler flags
1356   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1357               nonstandard directory <lib dir>
1358   LIBS        libraries to pass to the linker, e.g. -l<library>
1359   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1360               you have headers in a nonstandard directory <include dir>
1361   CPP         C preprocessor
1362
1363 Use these variables to override the choices made by `configure' or to help
1364 it to find libraries and programs with nonstandard names/locations.
