1228 \`configure' configures RISC-V ISA Simulator ? to adapt to many kinds of systems.
1229
1230 Usage: $0 [OPTION]... [VAR=VALUE]...
1231
1232 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1233 VAR=VALUE.  See below for descriptions of some of the useful variables.
1234
1235 Defaults for the options are specified in brackets.
1236
1237 Configuration:
1238   -h, --help              display this help and exit
1239       --help=short        display options specific to this package
1240       --help=recursive    display the short help of all the included packages
1241   -V, --version           display version information and exit
1242   -q, --quiet, --silent   do not print \`checking ...' messages
1243       --cache-file=FILE   cache test results in FILE [disabled]
1244   -C, --config-cache      alias for \`--cache-file=config.cache'
1245   -n, --no-create         do not create output files
1246       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1247
1248 Installation directories:
1249   --prefix=PREFIX         install architecture-independent files in PREFIX
1250                           [$ac_default_prefix]
1251   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1252                           [PREFIX]
1253
1254 By default, \`make install' will install all the files in
1255 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1256 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1257 for instance \`--prefix=\$HOME'.
1258
1259 For better control, use the options below.

1262   --bindir=DIR            user executables [EPREFIX/bin]

1314 Some influential environment variables:
1315   CC          C compiler command
1316   CFLAGS      C compiler flags
1317   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1318               nonstandard directory <lib dir>
1319   LIBS        libraries to pass to the linker, e.g. -l<library>
1320   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1321               you have headers in a nonstandard directory <include dir>
1322   CXX         C++ compiler command
1323   CXXFLAGS    C++ compiler flags
1324   STOW_ROOT   Root for non-native stow-based installs
1325   STOW_PREFIX Prefix for stow-based installs
1326   CPP         C preprocessor
1327
1328 Use these variables to override the choices made by `configure' or to help
1329 it to find libraries and programs with nonstandard names/locations.
