1208 \`configure' configures this package to adapt to many kinds of systems.
1209
1210 Usage: $0 [OPTION]... [VAR=VALUE]...
1211
1212 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1213 VAR=VALUE.  See below for descriptions of some of the useful variables.
1214
1215 Defaults for the options are specified in brackets.
1216
1217 Configuration:
1218   -h, --help              display this help and exit
1219       --help=short        display options specific to this package
1220       --help=recursive    display the short help of all the included packages
1221   -V, --version           display version information and exit
1222   -q, --quiet, --silent   do not print \`checking...' messages
1223       --cache-file=FILE   cache test results in FILE [disabled]
1224   -C, --config-cache      alias for \`--cache-file=config.cache'
1225   -n, --no-create         do not create output files
1226       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1227
1228 Installation directories:
1229   --prefix=PREFIX         install architecture-independent files in PREFIX
1230                           [$ac_default_prefix]
1231   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1232                           [PREFIX]
1233
1234 By default, \`make install' will install all the files in
1235 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1236 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1237 for instance \`--prefix=\$HOME'.
1238
1239 For better control, use the options below.

1241 Fine tuning of the installation directories:

1284   --enable-FEATURE[=ARG]  include FEATURE [ARG=yes]
1285   --enable-sim            Enable the GNU simulator
1286
1287 Some influential environment variables:
1288   CC          C compiler command
1289   CFLAGS      C compiler flags
1290   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1291               nonstandard directory <lib dir>
1292   LIBS        libraries to pass to the linker, e.g. -l<library>
1293   CPPFLAGS    C/C++/Objective C preprocessor flags, e.g. -I<include dir> if
1294               you have headers in a nonstandard directory <include dir>
1295
1296 Use these variables to override the choices made by `configure' or to help
1297 it to find libraries and programs with nonstandard names/locations.
