1197 \`configure' configures RISC-V ISA Simulator ? to adapt to many kinds of systems.
1198
1199 Usage: $0 [OPTION]... [VAR=VALUE]...
1200
1201 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1202 VAR=VALUE.  See below for descriptions of some of the useful variables.
1203
1204 Defaults for the options are specified in brackets.
1205
1206 Configuration:
1207   -h, --help              display this help and exit
1208       --help=short        display options specific to this package
1209       --help=recursive    display the short help of all the included packages
1210   -V, --version           display version information and exit
1211   -q, --quiet, --silent   do not print \`checking...' messages
1212       --cache-file=FILE   cache test results in FILE [disabled]
1213   -C, --config-cache      alias for \`--cache-file=config.cache'
1214   -n, --no-create         do not create output files
1215       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1216
1217 Installation directories:
1218   --prefix=PREFIX         install architecture-independent files in PREFIX
1219                           [$ac_default_prefix]
1220   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1221                           [PREFIX]
1222
1223 By default, \`make install' will install all the files in
1224 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1225 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1226 for instance \`--prefix=\$HOME'.
1227
1228 For better control, use the options below.

1230 Fine tuning of the installation directories:
1231   --bindir=DIR            user executables [EPREFIX/bin]
1232   --sbindir=DIR           system admin executables [EPREFIX/sbin]

1278   CC          C compiler command
1279   CFLAGS      C compiler flags
1280   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1281               nonstandard directory <lib dir>
1282   LIBS        libraries to pass to the linker, e.g. -l<library>
1283   CPPFLAGS    C/C++/Objective C preprocessor flags, e.g. -I<include dir> if
1284               you have headers in a nonstandard directory <include dir>
1285   CXX         C++ compiler command
1286   CXXFLAGS    C++ compiler flags
1287   STOW_ROOT   Root for non-native stow-based installs
1288   STOW_PREFIX Prefix for stow-based installs
1289   CPP         C preprocessor
1290
1291 Use these variables to override the choices made by `configure' or to help
1292 it to find libraries and programs with nonstandard names/locations.
