1224 \`configure' configures RISC-V ISA Simulator ? to adapt to many kinds of systems.
1225
1226 Usage: $0 [OPTION]... [VAR=VALUE]...
1227
1228 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1229 VAR=VALUE. See below for descriptions of some of the useful variables.
1230
1231 Defaults for the options are specified in brackets.
1232
1233 Configuration:
1234 -h, --help display this help and exit
1235 --help=short display options specific to this package
1236 --help=recursive display the short help of all the included packages
1237 -V, --version display version information and exit
1238 -q, --quiet, --silent do not print \`checking ...' messages
1239 --cache-file=FILE cache test results in FILE [disabled]
1240 -C, --config-cache alias for \`--cache-file=config.cache'
1241 -n, --no-create do not create output files
1242 --srcdir=DIR find the sources in DIR [configure dir or \`..']
1243
1244 Installation directories:
1245 --prefix=PREFIX install architecture-independent files in PREFIX
1246 [$ac_default_prefix]
1247 --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
1248 [PREFIX]
1249
1250 By default, \`make install' will install all the files in
1251 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
1252 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1253 for instance \`--prefix=\$HOME'.
1254
1255 For better control, use the options below.
1256
1257 Fine tuning of the installation directories:
1258 --bindir=DIR user executables [EPREFIX/bin]
1259 --sbindir=DIR system admin executables [EPREFIX/sbin]
1260 --libexecdir=DIR program executables [EPREFIX/libexec]
1261 --sysconfdir=DIR read-only single-machine data [PREFIX/etc]
1262 --sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]
1263 --localstatedir=DIR modifiable single-machine data [PREFIX/var]
1264 --libdir=DIR object code libraries [EPREFIX/lib]
1265 --includedir=DIR C header files [PREFIX/include]
1266 --oldincludedir=DIR C header files for non-gcc [/usr/include]
1267 --datarootdir=DIR read-only arch.-independent data root [PREFIX/share]
1268 --datadir=DIR read-only architecture-independent data [DATAROOTDIR]
1269 --infodir=DIR info documentation [DATAROOTDIR/info]

1293 Optional Features:
1294 --disable-option-checking ignore unrecognized --enable/--with options
1295 --disable-FEATURE do not include FEATURE (same as --enable-FEATURE=no)
1296 --enable-FEATURE[=ARG] include FEATURE [ARG=yes]
1297 --enable-stow Enable stow-based install
1298 --enable-optional-subprojects
1299 Enable all optional subprojects
1300 --enable-commitlog Enable commit log generation
1301 --enable-histogram Enable PC histogram generation
1302
1303 Optional Packages:
1304 --with-PACKAGE[=ARG] use PACKAGE [ARG=yes]
1305 --without-PACKAGE do not use PACKAGE (same as --with-PACKAGE=no)
1306 --with-fesvr path to your fesvr installation if not in a standard
1307 location
1308
1309 Some influential environment variables:
1310 CC C compiler command
1311 CFLAGS C compiler flags
1312 LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
1313 nonstandard directory <lib dir>
1314 LIBS libraries to pass to the linker, e.g. -l<library>
1315 CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1316 you have headers in a nonstandard directory <include dir>
1317 CXX C++ compiler command
1318 CXXFLAGS C++ compiler flags
1319 STOW_ROOT Root for non-native stow-based installs
1320 STOW_PREFIX Prefix for stow-based installs
1321 CXXCPP C++ preprocessor
1322
1323 Use these variables to override the choices made by `configure' or to help
1324 it to find libraries and programs with nonstandard names/locations.
