1211 \`configure' configures RISC-V ISA Simulator ? to adapt to many kinds of systems.
1212
1213 Usage: $0 [OPTION]... [VAR=VALUE]...
1214
1215 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1216 VAR=VALUE.  See below for descriptions of some of the useful variables.
1217
1218 Defaults for the options are specified in brackets.
1219
1220 Configuration:
1221   -h, --help              display this help and exit
1222       --help=short        display options specific to this package
1223       --help=recursive    display the short help of all the included packages
1224   -V, --version           display version information and exit
1225   -q, --quiet, --silent   do not print \`checking ...' messages
1226       --cache-file=FILE   cache test results in FILE [disabled]
1227   -C, --config-cache      alias for \`--cache-file=config.cache'
1228   -n, --no-create         do not create output files
1229       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1230
1231 Installation directories:
1232   --prefix=PREFIX         install architecture-independent files in PREFIX
1233                           [$ac_default_prefix]
1234   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1235                           [PREFIX]
1236
1237 By default, \`make install' will install all the files in
1238 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1239 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1240 for instance \`--prefix=\$HOME'.
1241
1242 For better control, use the options below.

1298 Some influential environment variables:
1299   CC          C compiler command
1300   CFLAGS      C compiler flags
1301   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1302               nonstandard directory <lib dir>
1303   LIBS        libraries to pass to the linker, e.g. -l<library>
1304   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1305               you have headers in a nonstandard directory <include dir>
1306   CXX         C++ compiler command
1307   CXXFLAGS    C++ compiler flags
1308   STOW_ROOT   Root for non-native stow-based installs
1309   STOW_PREFIX Prefix for stow-based installs
1310   CPP         C preprocessor
1311
1312 Use these variables to override the choices made by `configure' or to help
1313 it to find libraries and programs with nonstandard names/locations.
