1196 \`configure' configures RISC-V ISA Simulator ? to adapt to many kinds of systems.
1197
1198 Usage: $0 [OPTION]... [VAR=VALUE]...
1199
1200 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1201 VAR=VALUE. See below for descriptions of some of the useful variables.
1202
1203 Defaults for the options are specified in brackets.
1204
1205 Configuration:
1206 -h, --help display this help and exit
1207 --help=short display options specific to this package
1208 --help=recursive display the short help of all the included packages
1209 -V, --version display version information and exit
1210 -q, --quiet, --silent do not print \`checking...' messages
1211 --cache-file=FILE cache test results in FILE [disabled]
1212 -C, --config-cache alias for \`--cache-file=config.cache'
1213 -n, --no-create do not create output files
1214 --srcdir=DIR find the sources in DIR [configure dir or \`..']
1215
1216 Installation directories:
1217 --prefix=PREFIX install architecture-independent files in PREFIX
1218 [$ac_default_prefix]
1219 --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
1220 [PREFIX]
1221
1222 By default, \`make install' will install all the files in
1223 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
1224 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1225 for instance \`--prefix=\$HOME'.
1226
1227 For better control, use the options below.
1228
1229 Fine tuning of the installation directories:
1230 --bindir=DIR user executables [EPREFIX/bin]
1231 --sbindir=DIR system admin executables [EPREFIX/sbin]
1232 --libexecdir=DIR program executables [EPREFIX/libexec]
1233 --sysconfdir=DIR read-only single-machine data [PREFIX/etc]
1234 --sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]
1235 --localstatedir=DIR modifiable single-machine data [PREFIX/var]
1236 --libdir=DIR object code libraries [EPREFIX/lib]
1237 --includedir=DIR C header files [PREFIX/include]
1238 --oldincludedir=DIR C header files for non-gcc [/usr/include]
1239 --datarootdir=DIR read-only arch.-independent data root [PREFIX/share]
1240 --datadir=DIR read-only architecture-independent data [DATAROOTDIR]

1268 --enable-FEATURE[=ARG] include FEATURE [ARG=yes]
1269 --enable-stow Enable stow-based install
1270 --enable-optional-subprojects
1271 Enable all optional subprojects
1272 --disable-fpu Disable floating-point
1273 --disable-64bit Disable 64-bit mode
1274
1275 Some influential environment variables:
1276 CC C compiler command
1277 CFLAGS C compiler flags
1278 LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
1279 nonstandard directory <lib dir>
1280 LIBS libraries to pass to the linker, e.g. -l<library>
1281 CPPFLAGS C/C++/Objective C preprocessor flags, e.g. -I<include dir> if
1282 you have headers in a nonstandard directory <include dir>
1283 CXX C++ compiler command
1284 CXXFLAGS C++ compiler flags
1285 STOW_ROOT Root for non-native stow-based installs
1286 STOW_PREFIX Prefix for stow-based installs
1287 CPP C preprocessor
1288
1289 Use these variables to override the choices made by `configure' or to help
1290 it to find libraries and programs with nonstandard names/locations.
