1199 \`configure' configures RISC-V ISA Simulator ? to adapt to many kinds of systems.
1200
1201 Usage: $0 [OPTION]... [VAR=VALUE]...
1202
1203 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1204 VAR=VALUE. See below for descriptions of some of the useful variables.
1205
1206 Defaults for the options are specified in brackets.
1207
1208 Configuration:
1209 -h, --help display this help and exit
1210 --help=short display options specific to this package
1211 --help=recursive display the short help of all the included packages
1212 -V, --version display version information and exit
1213 -q, --quiet, --silent do not print \`checking...' messages
1214 --cache-file=FILE cache test results in FILE [disabled]
1215 -C, --config-cache alias for \`--cache-file=config.cache'
1216 -n, --no-create do not create output files
1217 --srcdir=DIR find the sources in DIR [configure dir or \`..']
1218
1219 Installation directories:
1220 --prefix=PREFIX install architecture-independent files in PREFIX
1221 [$ac_default_prefix]
1222 --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
1223 [PREFIX]
1224
1225 By default, \`make install' will install all the files in
1226 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
1227 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1228 for instance \`--prefix=\$HOME'.
1229
1230 For better control, use the options below.
1231
1232 Fine tuning of the installation directories:
1233 --bindir=DIR user executables [EPREFIX/bin]
1234 --sbindir=DIR system admin executables [EPREFIX/sbin]
1235 --libexecdir=DIR program executables [EPREFIX/libexec]
1236 --sysconfdir=DIR read-only single-machine data [PREFIX/etc]
1237 --sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]
1238 --localstatedir=DIR modifiable single-machine data [PREFIX/var]
1239 --libdir=DIR object code libraries [EPREFIX/lib]
1240 --includedir=DIR C header files [PREFIX/include]
1241 --oldincludedir=DIR C header files for non-gcc [/usr/include]
1242 --datarootdir=DIR read-only arch.-independent data root [PREFIX/share]
1243 --datadir=DIR read-only architecture-independent data [DATAROOTDIR]
1244 --infodir=DIR info documentation [DATAROOTDIR/info]

1270 --disable-FEATURE do not include FEATURE (same as --enable-FEATURE=no)
1271 --enable-FEATURE[=ARG] include FEATURE [ARG=yes]
1272 --enable-stow Enable stow-based install
1273 --enable-optional-subprojects
1274 Enable all optional subprojects
1275 --disable-fpu Disable floating-point
1276 --disable-64bit Disable 64-bit mode
1277 --enable-rvc Enable instruction compression
1278 --disable-vec Disable vector processor
1279
1280 Some influential environment variables:
1281 CC C compiler command
1282 CFLAGS C compiler flags
1283 LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
1284 nonstandard directory <lib dir>
1285 LIBS libraries to pass to the linker, e.g. -l<library>
1286 CPPFLAGS C/C++/Objective C preprocessor flags, e.g. -I<include dir> if
1287 you have headers in a nonstandard directory <include dir>
1288 CXX C++ compiler command
1289 CXXFLAGS C++ compiler flags
1290 STOW_ROOT Root for non-native stow-based installs
1291 STOW_PREFIX Prefix for stow-based installs
1292 CPP C preprocessor
1293
1294 Use these variables to override the choices made by `configure' or to help
1295 it to find libraries and programs with nonstandard names/locations.
