1198 \`configure' configures RISC-V ISA Simulator ? to adapt to many kinds of systems.
1199
1200 Usage: $0 [OPTION]... [VAR=VALUE]...
1201
1202 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1203 VAR=VALUE.  See below for descriptions of some of the useful variables.
1204
1205 Defaults for the options are specified in brackets.
1206
1207 Configuration:
1208   -h, --help              display this help and exit
1209       --help=short        display options specific to this package
1210       --help=recursive    display the short help of all the included packages
1211   -V, --version           display version information and exit
1212   -q, --quiet, --silent   do not print \`checking...' messages
1213       --cache-file=FILE   cache test results in FILE [disabled]
1214   -C, --config-cache      alias for \`--cache-file=config.cache'
1215   -n, --no-create         do not create output files
1216       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1217
1218 Installation directories:
1219   --prefix=PREFIX         install architecture-independent files in PREFIX
1220                           [$ac_default_prefix]
1221   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1222                           [PREFIX]
1223
1224 By default, \`make install' will install all the files in
1225 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1226 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1227 for instance \`--prefix=\$HOME'.
1228
1229 For better control, use the options below.

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

1279 Some influential environment variables:
1280   CC          C compiler command
1281   CFLAGS      C compiler flags
1282   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1283               nonstandard directory <lib dir>
1284   LIBS        libraries to pass to the linker, e.g. -l<library>
1285   CPPFLAGS    C/C++/Objective C preprocessor flags, e.g. -I<include dir> if
1286               you have headers in a nonstandard directory <include dir>
1287   CXX         C++ compiler command
1288   CXXFLAGS    C++ compiler flags
1289   STOW_ROOT   Root for non-native stow-based installs
1290   STOW_PREFIX Prefix for stow-based installs
1291   CPP         C preprocessor
1292
1293 Use these variables to override the choices made by `configure' or to help
1294 it to find libraries and programs with nonstandard names/locations.
