1209 \`configure' configures RISC-V ISA Simulator ? to adapt to many kinds of systems.
1210
1211 Usage: $0 [OPTION]... [VAR=VALUE]...
1212
1213 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1214 VAR=VALUE. See below for descriptions of some of the useful variables.
1215
1216 Defaults for the options are specified in brackets.
1217
1218 Configuration:
1219 -h, --help display this help and exit
1220 --help=short display options specific to this package
1221 --help=recursive display the short help of all the included packages
1222 -V, --version display version information and exit
1223 -q, --quiet, --silent do not print \`checking ...' messages
1224 --cache-file=FILE cache test results in FILE [disabled]
1225 -C, --config-cache alias for \`--cache-file=config.cache'
1226 -n, --no-create do not create output files
1227 --srcdir=DIR find the sources in DIR [configure dir or \`..']
1228
1229 Installation directories:
1230 --prefix=PREFIX install architecture-independent files in PREFIX
1231 [$ac_default_prefix]
1232 --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
1233 [PREFIX]
1234
1235 By default, \`make install' will install all the files in
1236 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
1237 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1238 for instance \`--prefix=\$HOME'.
1239
1240 For better control, use the options below.
1241
1242 Fine tuning of the installation directories:
1243 --bindir=DIR user executables [EPREFIX/bin]
1244 --sbindir=DIR system admin executables [EPREFIX/sbin]
1245 --libexecdir=DIR program executables [EPREFIX/libexec]
1246 --sysconfdir=DIR read-only single-machine data [PREFIX/etc]
1247 --sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]
1248 --localstatedir=DIR modifiable single-machine data [PREFIX/var]
1249 --libdir=DIR object code libraries [EPREFIX/lib]
1250 --includedir=DIR C header files [PREFIX/include]
1251 --oldincludedir=DIR C header files for non-gcc [/usr/include]
1252 --datarootdir=DIR read-only arch.-independent data root [PREFIX/share]
1253 --datadir=DIR read-only architecture-independent data [DATAROOTDIR]

1280 --disable-FEATURE do not include FEATURE (same as --enable-FEATURE=no)
1281 --enable-FEATURE[=ARG] include FEATURE [ARG=yes]
1282 --enable-stow Enable stow-based install
1283 --enable-optional-subprojects
1284 Enable all optional subprojects
1285 --disable-fpu Disable floating-point
1286 --disable-64bit Disable 64-bit mode
1287
1288 Optional Packages:
1289 --with-PACKAGE[=ARG] use PACKAGE [ARG=yes]
1290 --without-PACKAGE do not use PACKAGE (same as --with-PACKAGE=no)
1291 --with-fesvr path to your fesvr installation if not in a standard
1292 location
1293
1294 Some influential environment variables:
1295 CC C compiler command
1296 CFLAGS C compiler flags
1297 LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
1298 nonstandard directory <lib dir>
1299 LIBS libraries to pass to the linker, e.g. -l<library>
1300 CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1301 you have headers in a nonstandard directory <include dir>
1302 CXX C++ compiler command
1303 CXXFLAGS C++ compiler flags
1304 STOW_ROOT Root for non-native stow-based installs
1305 STOW_PREFIX Prefix for stow-based installs
1306 CPP C preprocessor
1307
1308 Use these variables to override the choices made by `configure' or to help
1309 it to find libraries and programs with nonstandard names/locations.
