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.

1232 Fine tuning of the installation directories:
1233   --bindir=DIR            user executables [EPREFIX/bin]

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.
