1261 \`configure' configures RISC-V ISA Simulator ? to adapt to many kinds of systems.
1262
1263 Usage: $0 [OPTION]... [VAR=VALUE]...
1264
1265 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1266 VAR=VALUE. See below for descriptions of some of the useful variables.
1267
1268 Defaults for the options are specified in brackets.
1269
1270 Configuration:
1271 -h, --help display this help and exit
1272 --help=short display options specific to this package
1273 --help=recursive display the short help of all the included packages
1274 -V, --version display version information and exit
1275 -q, --quiet, --silent do not print \`checking ...' messages
1276 --cache-file=FILE cache test results in FILE [disabled]
1277 -C, --config-cache alias for \`--cache-file=config.cache'
1278 -n, --no-create do not create output files
1279 --srcdir=DIR find the sources in DIR [configure dir or \`..']
1280
1281 Installation directories:
1282 --prefix=PREFIX install architecture-independent files in PREFIX
1283 [$ac_default_prefix]
1284 --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
1285 [PREFIX]
1286
1287 By default, \`make install' will install all the files in
1288 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
1289 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1290 for instance \`--prefix=\$HOME'.
1291
1292 For better control, use the options below.
1293
1294 Fine tuning of the installation directories:
1295 --bindir=DIR user executables [EPREFIX/bin]
1296 --sbindir=DIR system admin executables [EPREFIX/sbin]
1297 --libexecdir=DIR program executables [EPREFIX/libexec]
1298 --sysconfdir=DIR read-only single-machine data [PREFIX/etc]
1299 --sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]
1300 --localstatedir=DIR modifiable single-machine data [PREFIX/var]
1301 --libdir=DIR object code libraries [EPREFIX/lib]
1302 --includedir=DIR C header files [PREFIX/include]
1303 --oldincludedir=DIR C header files for non-gcc [/usr/include]
1304 --datarootdir=DIR read-only arch.-independent data root [PREFIX/share]
1305 --datadir=DIR read-only architecture-independent data [DATAROOTDIR]
1306 --infodir=DIR info documentation [DATAROOTDIR/info]

1331 --disable-option-checking ignore unrecognized --enable/--with options
1332 --disable-FEATURE do not include FEATURE (same as --enable-FEATURE=no)
1333 --enable-FEATURE[=ARG] include FEATURE [ARG=yes]
1334 --enable-stow Enable stow-based install
1335 --enable-optional-subprojects
1336 Enable all optional subprojects
1337 --enable-commitlog Enable commit log generation
1338 --enable-histogram Enable PC histogram generation
1339
1340 Optional Packages:
1341 --with-PACKAGE[=ARG] use PACKAGE [ARG=yes]
1342 --without-PACKAGE do not use PACKAGE (same as --with-PACKAGE=no)
1343 --with-isa=RV64IMAFDC Sets the default RISC-V ISA
1344 --with-fesvr path to your fesvr installation if not in a standard
1345 location
1346
1347 Some influential environment variables:
1348 CC C compiler command
1349 CFLAGS C compiler flags
1350 LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
1351 nonstandard directory <lib dir>
1352 LIBS libraries to pass to the linker, e.g. -l<library>
1353 CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1354 you have headers in a nonstandard directory <include dir>
1355 CXX C++ compiler command
1356 CXXFLAGS C++ compiler flags
1357 CXXCPP C++ preprocessor
1358 STOW_ROOT Root for non-native stow-based installs
1359 STOW_PREFIX Prefix for stow-based installs
1360
1361 Use these variables to override the choices made by `configure' or to help
1362 it to find libraries and programs with nonstandard names/locations.
