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

1300 --libdir=DIR object code libraries [EPREFIX/lib]
1301 --includedir=DIR C header files [PREFIX/include]
1302 --oldincludedir=DIR C header files for non-gcc [/usr/include]
1303 --datarootdir=DIR read-only arch.-independent data root [PREFIX/share]
1304 --datadir=DIR read-only architecture-independent data [DATAROOTDIR]
1305 --infodir=DIR info documentation [DATAROOTDIR/info]

1311 --pdfdir=DIR pdf documentation [DOCDIR]
1312 --psdir=DIR ps documentation [DOCDIR]
1318 --build=BUILD configure for building on BUILD [guessed]

1332 --disable-FEATURE do not include FEATURE (same as --enable-FEATURE=no)
1333 --enable-FEATURE[=ARG] include FEATURE [ARG=yes]
1334 --enable-build-with-cxx build with C++ compiler instead of C compiler
1335 --enable-werror-always enable -Werror despite compiler version
1336 --disable-rpath do not hardcode runtime library paths
1337 --enable-maintainer-mode enable rules only needed by maintainers
1338 --enable-checking enable expensive run-time checks
1341 --with-PACKAGE[=ARG] use PACKAGE [ARG=yes]
1342 --without-PACKAGE do not use PACKAGE (same as --with-PACKAGE=no)
1343 --with-gnu-ld assume the C compiler uses GNU ld default=no
1344 --with-libiconv-prefix[=DIR] search for libiconv in DIR/include and DIR/lib
1345 --without-libiconv-prefix don't search for libiconv in includedir and libdir
1347 Some influential environment variables:
1348 CC C compiler command
1349 CFLAGS C compiler flags
1350 LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
1351 nonstandard directory <lib dir>
1352 LIBS libraries to pass to the linker, e.g. -l<library>
1353 CPPFLAGS C/C++/Objective C preprocessor flags, e.g. -I<include dir> if
1354 you have headers in a nonstandard directory <include dir>
1355 CXX C++ compiler command
1356 CXXFLAGS C++ compiler flags
1358 CXXCPP C++ preprocessor
1360 Use these variables to override the choices made by `configure' or to help
1361 it to find libraries and programs with nonstandard names/locations.
