1275 \`configure' configures RISC-V ISA Simulator ? to adapt to many kinds of systems.
1276
1277 Usage: $0 [OPTION]... [VAR=VALUE]...
1278
1279 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1280 VAR=VALUE. See below for descriptions of some of the useful variables.
1281
1282 Defaults for the options are specified in brackets.
1283
1284 Configuration:
1285 -h, --help display this help and exit
1286 --help=short display options specific to this package
1287 --help=recursive display the short help of all the included packages
1288 -V, --version display version information and exit
1289 -q, --quiet, --silent do not print \`checking ...' messages
1290 --cache-file=FILE cache test results in FILE [disabled]
1291 -C, --config-cache alias for \`--cache-file=config.cache'
1292 -n, --no-create do not create output files
1293 --srcdir=DIR find the sources in DIR [configure dir or \`..']
1294
1295 Installation directories:
1296 --prefix=PREFIX install architecture-independent files in PREFIX
1297 [$ac_default_prefix]
1298 --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
1299 [PREFIX]
1300
1301 By default, \`make install' will install all the files in
1302 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
1303 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1304 for instance \`--prefix=\$HOME'.
1305
1306 For better control, use the options below.
1307
1308 Fine tuning of the installation directories:
1309 --bindir=DIR user executables [EPREFIX/bin]
1310 --sbindir=DIR system admin executables [EPREFIX/sbin]
1311 --libexecdir=DIR program executables [EPREFIX/libexec]
1312 --sysconfdir=DIR read-only single-machine data [PREFIX/etc]
1313 --sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]
1314 --localstatedir=DIR modifiable single-machine data [PREFIX/var]
1315 --runstatedir=DIR modifiable per-process data [LOCALSTATEDIR/run]
1316 --libdir=DIR object code libraries [EPREFIX/lib]
1317 --includedir=DIR C header files [PREFIX/include]
1318 --oldincludedir=DIR C header files for non-gcc [/usr/include]

1347 --disable-FEATURE do not include FEATURE (same as --enable-FEATURE=no)
1348 --enable-FEATURE[=ARG] include FEATURE [ARG=yes]
1349 --enable-stow Enable stow-based install
1350 --enable-optional-subprojects
1351 Enable all optional subprojects
1352 --enable-commitlog Enable commit log generation
1353 --enable-histogram Enable PC histogram generation
1354 --enable-dirty Enable hardware management of PTE accessed and dirty
1355 bits
1356 --enable-misaligned Enable hardware support for misaligned loads and
1357 stores
1358
1359 Optional Packages:
1360 --with-PACKAGE[=ARG] use PACKAGE [ARG=yes]
1361 --without-PACKAGE do not use PACKAGE (same as --with-PACKAGE=no)
1362 --with-isa=RV64IMAFDC Sets the default RISC-V ISA
1363 --with-fesvr path to your fesvr installation if not in a standard
1364 location
1365
1366 Some influential environment variables:
1367 CC C compiler command
1368 CFLAGS C compiler flags
1369 LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
1370 nonstandard directory <lib dir>
1371 LIBS libraries to pass to the linker, e.g. -l<library>
1372 CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1373 you have headers in a nonstandard directory <include dir>
1374 CXX C++ compiler command
1375 CXXFLAGS C++ compiler flags
1376 CXXCPP C++ preprocessor
1377 STOW_ROOT Root for non-native stow-based installs
1378 STOW_PREFIX Prefix for stow-based installs
1379
1380 Use these variables to override the choices made by `configure' or to help
1381 it to find libraries and programs with nonstandard names/locations.
