1274 \`configure' configures RISC-V ISA Simulator ? to adapt to many kinds of systems.
1275
1276 Usage: $0 [OPTION]... [VAR=VALUE]...
1277
1278 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1279 VAR=VALUE. See below for descriptions of some of the useful variables.
1280
1281 Defaults for the options are specified in brackets.
1282
1283 Configuration:
1284 -h, --help display this help and exit
1285 --help=short display options specific to this package
1286 --help=recursive display the short help of all the included packages
1287 -V, --version display version information and exit
1288 -q, --quiet, --silent do not print \`checking ...' messages
1289 --cache-file=FILE cache test results in FILE [disabled]
1290 -C, --config-cache alias for \`--cache-file=config.cache'
1291 -n, --no-create do not create output files
1292 --srcdir=DIR find the sources in DIR [configure dir or \`..']
1293
1294 Installation directories:
1295 --prefix=PREFIX install architecture-independent files in PREFIX
1296 [$ac_default_prefix]
1297 --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
1298 [PREFIX]
1299
1300 By default, \`make install' will install all the files in
1301 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
1302 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1303 for instance \`--prefix=\$HOME'.
1304
1305 For better control, use the options below.
1306
1307 Fine tuning of the installation directories:
1308 --bindir=DIR user executables [EPREFIX/bin]
1309 --sbindir=DIR system admin executables [EPREFIX/sbin]
1310 --libexecdir=DIR program executables [EPREFIX/libexec]
1311 --sysconfdir=DIR read-only single-machine data [PREFIX/etc]
1312 --sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]
1313 --localstatedir=DIR modifiable single-machine data [PREFIX/var]
1314 --runstatedir=DIR modifiable per-process data [LOCALSTATEDIR/run]
1315 --libdir=DIR object code libraries [EPREFIX/lib]
1316 --includedir=DIR C header files [PREFIX/include]
1317 --oldincludedir=DIR C header files for non-gcc [/usr/include]

1347 --enable-FEATURE[=ARG] include FEATURE [ARG=yes]
1348 --enable-stow Enable stow-based install
1349 --enable-optional-subprojects
1350 Enable all optional subprojects
1351 --enable-commitlog Enable commit log generation
1352 --enable-histogram Enable PC histogram generation
1353 --enable-dirty Enable hardware management of PTE accessed and dirty
1354 bits

1356 Optional Packages:
1357 --with-PACKAGE[=ARG] use PACKAGE [ARG=yes]
1358 --without-PACKAGE do not use PACKAGE (same as --with-PACKAGE=no)
1359 --with-isa=RV64IMAFDC Sets the default RISC-V ISA
1360 --with-fesvr path to your fesvr installation if not in a standard
1361 location
1362
1363 Some influential environment variables:
1364 CC C compiler command
1365 CFLAGS C compiler flags
1366 LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
1367 nonstandard directory <lib dir>
1368 LIBS libraries to pass to the linker, e.g. -l<library>
1369 CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1370 you have headers in a nonstandard directory <include dir>
1371 CXX C++ compiler command
1372 CXXFLAGS C++ compiler flags
1373 CXXCPP C++ preprocessor
1374 STOW_ROOT Root for non-native stow-based installs
1375 STOW_PREFIX Prefix for stow-based installs
1376
1377 Use these variables to override the choices made by `configure' or to help
1378 it to find libraries and programs with nonstandard names/locations.
