1194 \`configure' configures RISC-V ISA Simulator ? to adapt to many kinds of systems.
1195
1196 Usage: $0 [OPTION]... [VAR=VALUE]...
1197
1198 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1199 VAR=VALUE.  See below for descriptions of some of the useful variables.
1200
1201 Defaults for the options are specified in brackets.
1202
1203 Configuration:
1204   -h, --help              display this help and exit
1205       --help=short        display options specific to this package
1206       --help=recursive    display the short help of all the included packages
1207   -V, --version           display version information and exit
1208   -q, --quiet, --silent   do not print \`checking...' messages
1209       --cache-file=FILE   cache test results in FILE [disabled]
1210   -C, --config-cache      alias for \`--cache-file=config.cache'
1211   -n, --no-create         do not create output files
1212       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1213
1214 Installation directories:
1215   --prefix=PREFIX         install architecture-independent files in PREFIX
1216                           [$ac_default_prefix]
1217   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1218                           [PREFIX]
1219
1220 By default, \`make install' will install all the files in
1221 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1222 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1223 for instance \`--prefix=\$HOME'.
1224
1225 For better control, use the options below.

1227 Fine tuning of the installation directories:
1228   --bindir=DIR            user executables [EPREFIX/bin]
1229   --sbindir=DIR           system admin executables [EPREFIX/sbin]

1273   CFLAGS      C compiler flags
1274   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1275               nonstandard directory <lib dir>
1276   LIBS        libraries to pass to the linker, e.g. -l<library>
1277   CPPFLAGS    C/C++/Objective C preprocessor flags, e.g. -I<include dir> if
1278               you have headers in a nonstandard directory <include dir>
1279   CXX         C++ compiler command
1280   CXXFLAGS    C++ compiler flags
1281   STOW_ROOT   Root for non-native stow-based installs
1282   STOW_PREFIX Prefix for stow-based installs
1283   CPP         C preprocessor
1284
1285 Use these variables to override the choices made by `configure' or to help
1286 it to find libraries and programs with nonstandard names/locations.
