1229 \`configure' configures RISC-V ISA Simulator ? to adapt to many kinds of systems.
1230
1231 Usage: $0 [OPTION]... [VAR=VALUE]...
1232
1233 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1234 VAR=VALUE.  See below for descriptions of some of the useful variables.
1235
1236 Defaults for the options are specified in brackets.
1237
1238 Configuration:
1239   -h, --help              display this help and exit
1240       --help=short        display options specific to this package
1241       --help=recursive    display the short help of all the included packages
1242   -V, --version           display version information and exit
1243   -q, --quiet, --silent   do not print \`checking ...' messages
1244       --cache-file=FILE   cache test results in FILE [disabled]
1245   -C, --config-cache      alias for \`--cache-file=config.cache'
1246   -n, --no-create         do not create output files
1247       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1248
1249 Installation directories:
1250   --prefix=PREFIX         install architecture-independent files in PREFIX
1251                           [$ac_default_prefix]
1252   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1253                           [PREFIX]
1254
1255 By default, \`make install' will install all the files in
1256 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1257 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1258 for instance \`--prefix=\$HOME'.
1259
1260 For better control, use the options below.

1316 Some influential environment variables:
1317   CC          C compiler command
1318   CFLAGS      C compiler flags
1319   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1320               nonstandard directory <lib dir>
1321   LIBS        libraries to pass to the linker, e.g. -l<library>
1322   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1323               you have headers in a nonstandard directory <include dir>
1324   CXX         C++ compiler command
1325   CXXFLAGS    C++ compiler flags
1326   STOW_ROOT   Root for non-native stow-based installs
1327   STOW_PREFIX Prefix for stow-based installs
1328   CPP         C preprocessor
1329
1330 Use these variables to override the choices made by `configure' or to help
1331 it to find libraries and programs with nonstandard names/locations.
