1260 \`configure' configures RISC-V ISA Simulator ? to adapt to many kinds of systems.
1261
1262 Usage: $0 [OPTION]... [VAR=VALUE]...
1263
1264 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1265 VAR=VALUE. See below for descriptions of some of the useful variables.
1266
1267 Defaults for the options are specified in brackets.
1268
1269 Configuration:
1270 -h, --help display this help and exit
1271 --help=short display options specific to this package
1272 --help=recursive display the short help of all the included packages
1273 -V, --version display version information and exit
1274 -q, --quiet, --silent do not print \`checking ...' messages
1275 --cache-file=FILE cache test results in FILE [disabled]
1276 -C, --config-cache alias for \`--cache-file=config.cache'
1277 -n, --no-create do not create output files
1278 --srcdir=DIR find the sources in DIR [configure dir or \`..']
1279
1280 Installation directories:
1281 --prefix=PREFIX install architecture-independent files in PREFIX
1282 [$ac_default_prefix]
1283 --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
1284 [PREFIX]
1285
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'.
1290
1291 For better control, use the options below.
1292
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]
1299 --localstatedir=DIR modifiable single-machine data [PREFIX/var]
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]

1331 --disable-FEATURE do not include FEATURE (same as --enable-FEATURE=no)
1332 --enable-FEATURE[=ARG] include FEATURE [ARG=yes]
1333 --enable-stow Enable stow-based install
1334 --enable-optional-subprojects
1335 Enable all optional subprojects
1336 --enable-commitlog Enable commit log generation
1337 --enable-histogram Enable PC histogram generation
1338
1339 Optional Packages:
1340 --with-PACKAGE[=ARG] use PACKAGE [ARG=yes]
1341 --without-PACKAGE do not use PACKAGE (same as --with-PACKAGE=no)
1342 --with-fesvr path to your fesvr installation if not in a standard
1343 location
1344
1345 Some influential environment variables:
1346 CC C compiler command
1347 CFLAGS C compiler flags
1348 LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
1349 nonstandard directory <lib dir>
1350 LIBS libraries to pass to the linker, e.g. -l<library>
1351 CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1352 you have headers in a nonstandard directory <include dir>
1353 CXX C++ compiler command
1354 CXXFLAGS C++ compiler flags
1355 CXXCPP C++ preprocessor
1356 STOW_ROOT Root for non-native stow-based installs
1357 STOW_PREFIX Prefix for stow-based installs
1358
1359 Use these variables to override the choices made by `configure' or to help
1360 it to find libraries and programs with nonstandard names/locations.
