1255 \`configure' configures this package to adapt to many kinds of systems.
1256
1257 Usage: $0 [OPTION]... [VAR=VALUE]...
1258
1259 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1260 VAR=VALUE. See below for descriptions of some of the useful variables.
1261
1262 Defaults for the options are specified in brackets.
1263
1264 Configuration:
1265 -h, --help display this help and exit
1266 --help=short display options specific to this package
1267 --help=recursive display the short help of all the included packages
1268 -V, --version display version information and exit
1269 -q, --quiet, --silent do not print \`checking ...' messages
1270 --cache-file=FILE cache test results in FILE [disabled]
1271 -C, --config-cache alias for \`--cache-file=config.cache'
1272 -n, --no-create do not create output files
1273 --srcdir=DIR find the sources in DIR [configure dir or \`..']
1274
1275 Installation directories:
1276 --prefix=PREFIX install architecture-independent files in PREFIX
1277 [$ac_default_prefix]
1278 --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
1279 [PREFIX]
1280
1281 By default, \`make install' will install all the files in
1282 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
1283 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1284 for instance \`--prefix=\$HOME'.
1285
1286 For better control, use the options below.
1287
1288 Fine tuning of the installation directories:
1289 --bindir=DIR user executables [EPREFIX/bin]
1290 --sbindir=DIR system admin executables [EPREFIX/sbin]
1291 --libexecdir=DIR program executables [EPREFIX/libexec]
1292 --sysconfdir=DIR read-only single-machine data [PREFIX/etc]
1293 --sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]
1294 --localstatedir=DIR modifiable single-machine data [PREFIX/var]
1295 --libdir=DIR object code libraries [EPREFIX/lib]
1296 --includedir=DIR C header files [PREFIX/include]
1297 --oldincludedir=DIR C header files for non-gcc [/usr/include]
1298 --datarootdir=DIR read-only arch.-independent data root [PREFIX/share]
1299 --datadir=DIR read-only architecture-independent data [DATAROOTDIR]
1300 --infodir=DIR info documentation [DATAROOTDIR/info]

1323 Optional Features:
1324 --disable-option-checking ignore unrecognized --enable/--with options
1325 --disable-FEATURE do not include FEATURE (same as --enable-FEATURE=no)
1326 --enable-FEATURE[=ARG] include FEATURE [ARG=yes]
1327 --enable-c++-tools build auxiliary c++ tools
1328 --enable-maintainer-mode
1329 enable maintainer mode. Add rules to rebuild
1330 configurey bits
1331 --enable-checking[=LIST]
1332 enable expensive run-time checks. With LIST, enable
1333 only specific categories of checks. Categories are:
1334 yes,no,all,none,release.
1335 --enable-default-pie enable Position Independent Executable as default
1336
1337 Optional Packages:
1338 --with-PACKAGE[=ARG] use PACKAGE [ARG=yes]
1339 --without-PACKAGE do not use PACKAGE (same as --with-PACKAGE=no)
1340 --with-gcc-major-version-only
1341 use only GCC major number in filesystem paths
1342
1343 Some influential environment variables:
1344 CXX C++ compiler command
1345 CXXFLAGS C++ compiler flags
1346 LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
1347 nonstandard directory <lib dir>
1348 LIBS libraries to pass to the linker, e.g. -l<library>
1349 CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1350 you have headers in a nonstandard directory <include dir>
1351 CXXCPP C++ preprocessor
1352
1353 Use these variables to override the choices made by `configure' or to help
1354 it to find libraries and programs with nonstandard names/locations.
1355
1356 Report bugs to the package provider.
