1211 \`configure' configures RISC-V ISA Simulator ? to adapt to many kinds of systems.
1212
1213 Usage: $0 [OPTION]... [VAR=VALUE]...
1214
1215 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1216 VAR=VALUE. See below for descriptions of some of the useful variables.
1217
1218 Defaults for the options are specified in brackets.
1219
1220 Configuration:
1221 -h, --help display this help and exit
1222 --help=short display options specific to this package
1223 --help=recursive display the short help of all the included packages
1224 -V, --version display version information and exit
1225 -q, --quiet, --silent do not print \`checking ...' messages
1226 --cache-file=FILE cache test results in FILE [disabled]
1227 -C, --config-cache alias for \`--cache-file=config.cache'
1228 -n, --no-create do not create output files
1229 --srcdir=DIR find the sources in DIR [configure dir or \`..']
1230
1231 Installation directories:
1232 --prefix=PREFIX install architecture-independent files in PREFIX
1233 [$ac_default_prefix]
1234 --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
1235 [PREFIX]
1236
1237 By default, \`make install' will install all the files in
1238 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
1239 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1240 for instance \`--prefix=\$HOME'.
1241
1242 For better control, use the options below.
1243
1244 Fine tuning of the installation directories:
1245 --bindir=DIR user executables [EPREFIX/bin]
1246 --sbindir=DIR system admin executables [EPREFIX/sbin]
1247 --libexecdir=DIR program executables [EPREFIX/libexec]
1248 --sysconfdir=DIR read-only single-machine data [PREFIX/etc]
1249 --sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]
1250 --localstatedir=DIR modifiable single-machine data [PREFIX/var]
1251 --libdir=DIR object code libraries [EPREFIX/lib]
1252 --includedir=DIR C header files [PREFIX/include]
1253 --oldincludedir=DIR C header files for non-gcc [/usr/include]
1254 --datarootdir=DIR read-only arch.-independent data root [PREFIX/share]
1255 --datadir=DIR read-only architecture-independent data [DATAROOTDIR]
1256 --infodir=DIR info documentation [DATAROOTDIR/info]

1281 --disable-option-checking ignore unrecognized --enable/--with options
1282 --disable-FEATURE do not include FEATURE (same as --enable-FEATURE=no)
1283 --enable-FEATURE[=ARG] include FEATURE [ARG=yes]
1284 --enable-stow Enable stow-based install
1285 --enable-optional-subprojects
1286 Enable all optional subprojects
1287 --disable-fpu Disable floating-point
1288 --disable-64bit Disable 64-bit mode
1289 --enable-rvc Enable instruction compression
1290 --disable-vec Disable vector processor
1291
1292 Some influential environment variables:
1293 CC C compiler command
1294 CFLAGS C compiler flags
1295 LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
1296 nonstandard directory <lib dir>
1297 LIBS libraries to pass to the linker, e.g. -l<library>
1298 CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1299 you have headers in a nonstandard directory <include dir>
1300 CXX C++ compiler command
1301 CXXFLAGS C++ compiler flags
1302 STOW_ROOT Root for non-native stow-based installs
1303 STOW_PREFIX Prefix for stow-based installs
1304 CPP C preprocessor
1305
1306 Use these variables to override the choices made by `configure' or to help
1307 it to find libraries and programs with nonstandard names/locations.
