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

1317 --libdir=DIR object code libraries [EPREFIX/lib]
1318 --includedir=DIR C header files [PREFIX/include]

1349 --enable-FEATURE[=ARG] include FEATURE [ARG=yes]
1350 --enable-stow Enable stow-based install
1351 --disable-simplev Support for SimpleV (default enabled)
1352 --enable-optional-subprojects
1353 Enable all optional subprojects
1354 --enable-commitlog Enable commit log generation
1355 --enable-histogram Enable PC histogram generation
1356 --enable-dirty Enable hardware management of PTE accessed and dirty
1357 bits
1358 --enable-misaligned Enable hardware support for misaligned loads and

1360
1361 Optional Packages:
1362 --with-PACKAGE[=ARG] use PACKAGE [ARG=yes]
1363 --without-PACKAGE do not use PACKAGE (same as --with-PACKAGE=no)
1364 --with-isa=RV64IMAFDC Sets the default RISC-V ISA
1365 --with-fesvr path to your fesvr installation if not in a standard
1366 location
1367
1368 Some influential environment variables:
1369 CC C compiler command
1370 CFLAGS C compiler flags
1371 LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
1372 nonstandard directory <lib dir>
1373 LIBS libraries to pass to the linker, e.g. -l<library>
1374 CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1375 you have headers in a nonstandard directory <include dir>
1376 CXX C++ compiler command
1377 CXXFLAGS C++ compiler flags
1378 CXXCPP C++ preprocessor
1379 STOW_ROOT Root for non-native stow-based installs
1380 STOW_PREFIX Prefix for stow-based installs
1381
1382 Use these variables to override the choices made by `configure' or to help
1383 it to find libraries and programs with nonstandard names/locations.
