1287 \`configure' configures this package to adapt to many kinds of systems.
1288
1289 Usage: $0 [OPTION]... [VAR=VALUE]...
1290
1291 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1292 VAR=VALUE.  See below for descriptions of some of the useful variables.
1293
1294 Defaults for the options are specified in brackets.
1295
1296 Configuration:
1297   -h, --help              display this help and exit
1298       --help=short        display options specific to this package
1299       --help=recursive    display the short help of all the included packages
1300   -V, --version           display version information and exit
1301   -q, --quiet, --silent   do not print \`checking ...' messages
1302       --cache-file=FILE   cache test results in FILE [disabled]
1303   -C, --config-cache      alias for \`--cache-file=config.cache'
1304   -n, --no-create         do not create output files
1305       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1306
1307 Installation directories:
1308   --prefix=PREFIX         install architecture-independent files in PREFIX
1309                           [$ac_default_prefix]
1310   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1311                           [PREFIX]
1312
1313 By default, \`make install' will install all the files in
1314 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1315 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1316 for instance \`--prefix=\$HOME'.
1317
1318 For better control, use the options below.

1362   --disable-FEATURE       do not include FEATURE (same as --enable-FEATURE=no)
1363   --enable-FEATURE[=ARG]  include FEATURE [ARG=yes]
1364   --enable-maintainer-mode
1365                           enable make rules and dependencies not useful (and
1366                           sometimes confusing) to the casual installer
1367   --enable-sim-inline=inlines
1368                           Specify which functions should be inlined
1369   --enable-sim-scache=size
1370                           Specify simulator execution cache size
1371   --enable-sim-default-model=model
1372                           Specify default model to simulate
1373   --enable-cgen-maint=DIR build cgen generated files
1374   --enable-sim-hardware=LIST
1375                           Specify the hardware to be included in the build.
1376
1377 Some influential environment variables:
1378   CC          C compiler command
1379   CFLAGS      C compiler flags
1380   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1381               nonstandard directory <lib dir>
1382   LIBS        libraries to pass to the linker, e.g. -l<library>
1383   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1384               you have headers in a nonstandard directory <include dir>
1385   CPP         C preprocessor
1386
1387 Use these variables to override the choices made by `configure' or to help
1388 it to find libraries and programs with nonstandard names/locations.
