1249 \`configure' configures secnet 0.1.18+ to adapt to many kinds of systems.
1251 Usage: $0 [OPTION]... [VAR=VALUE]...
1253 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1254 VAR=VALUE. See below for descriptions of some of the useful variables.
1256 Defaults for the options are specified in brackets.
1259 -h, --help display this help and exit
1260 --help=short display options specific to this package
1261 --help=recursive display the short help of all the included packages
1262 -V, --version display version information and exit
1263 -q, --quiet, --silent do not print \`checking ...' messages
1264 --cache-file=FILE cache test results in FILE [disabled]
1265 -C, --config-cache alias for \`--cache-file=config.cache'
1266 -n, --no-create do not create output files
1267 --srcdir=DIR find the sources in DIR [configure dir or \`..']
1269 Installation directories:
1270 --prefix=PREFIX install architecture-independent files in PREFIX
1271 [$ac_default_prefix]
1272 --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
1275 By default, \`make install' will install all the files in
1276 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
1277 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1278 for instance \`--prefix=\$HOME'.
1280 For better control, use the options below.
1282 Fine tuning of the installation directories:
1283 --bindir=DIR user executables [EPREFIX/bin]
1284 --sbindir=DIR system admin executables [EPREFIX/sbin]
1285 --libexecdir=DIR program executables [EPREFIX/libexec]
1286 --sysconfdir=DIR read-only single-machine data [PREFIX/etc]
1287 --sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]
1288 --localstatedir=DIR modifiable single-machine data [PREFIX/var]
1289 --runstatedir=DIR modifiable per-process data [LOCALSTATEDIR/run]
1290 --libdir=DIR object code libraries [EPREFIX/lib]
1291 --includedir=DIR C header files [PREFIX/include]
1292 --oldincludedir=DIR C header files for non-gcc [/usr/include]
1293 --datarootdir=DIR read-only arch.-independent data root [PREFIX/share]
1294 --datadir=DIR read-only architecture-independent data [DATAROOTDIR]
1295 --infodir=DIR info documentation [DATAROOTDIR/info]

1321 Some influential environment variables:
1322 CC C compiler command
1323 CFLAGS C compiler flags
1324 LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
1325 nonstandard directory <lib dir>
1326 LIBS libraries to pass to the linker, e.g. -l<library>
1327 CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1328 you have headers in a nonstandard directory <include dir>
1331 Use these variables to override the choices made by `configure' or to help
1332 it to find libraries and programs with nonstandard names/locations.
