1280 \`configure' configures readline 8.0 to adapt to many kinds of systems.
1281
1282 Usage: $0 [OPTION]... [VAR=VALUE]...
1283
1284 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1285 VAR=VALUE.  See below for descriptions of some of the useful variables.
1286
1287 Defaults for the options are specified in brackets.
1288
1289 Configuration:
1290   -h, --help              display this help and exit
1291       --help=short        display options specific to this package
1292       --help=recursive    display the short help of all the included packages
1293   -V, --version           display version information and exit
1294   -q, --quiet, --silent   do not print \`checking ...' messages
1295       --cache-file=FILE   cache test results in FILE [disabled]
1296   -C, --config-cache      alias for \`--cache-file=config.cache'
1297   -n, --no-create         do not create output files
1298       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1299
1300 Installation directories:
1301   --prefix=PREFIX         install architecture-independent files in PREFIX
1302                           [$ac_default_prefix]
1303   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1304                           [PREFIX]
1305
1306 By default, \`make install' will install all the files in
1307 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1308 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1309 for instance \`--prefix=\$HOME'.
1310
1311 For better control, use the options below.

1354   --enable-static         build static libraries [[default=YES]]
1355   --disable-install-examples
1356                           don't install examples [[default=install]]
1357   --disable-largefile     omit support for large files
1358
1359 Optional Packages:
1360   --with-PACKAGE[=ARG]    use PACKAGE [ARG=yes]
1361   --without-PACKAGE       do not use PACKAGE (same as --with-PACKAGE=no)
1362   --with-curses           use the curses library instead of the termcap
1363                           library
1364
1365 Some influential environment variables:
1366   CC          C compiler command
1367   CFLAGS      C compiler flags
1368   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1369               nonstandard directory <lib dir>
1370   LIBS        libraries to pass to the linker, e.g. -l<library>
1371   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1372               you have headers in a nonstandard directory <include dir>
1373   CPP         C preprocessor
1374
1375 Use these variables to override the choices made by `configure' or to help
1376 it to find libraries and programs with nonstandard names/locations.
