'configure' configures RISC-V ISA Simulator ? to adapt to many kinds of systems.

Usage: $0 [OPTION]... [VAR=VALUE]...

To assign environment variables (e.g., CC, CFLAGS...), specify them as
VAR=VALUE.  See below for descriptions of some of the useful variables.

Defaults for the options are specified in brackets.

Configuration:
  -h, --help              display this help and exit
      --help=short        display options specific to this package
      --help=recursive    display the short help of all the included packages
  -V, --version           display version information and exit
  -q, --quiet, --silent   do not print 'checking ...' messages
      --cache-file=FILE   cache test results in FILE [disabled]
  -C, --config-cache      alias for '--cache-file=config.cache'
  -n, --no-create         do not create output files
      --srcdir=DIR        find the sources in DIR [configure dir or '..']

Installation directories:
  --prefix=PREFIX         install architecture-independent files in PREFIX
                          [$ac_default_prefix]
  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
                          [PREFIX]

By default, 'make install' will install all the files in
'$ac_default_prefix/bin', '$ac_default_prefix/lib' etc.  You can specify
an installation prefix other than '$ac_default_prefix' using '--prefix',
for instance '--prefix=\$HOME'.

For better control, use the options below.

Fine tuning of the installation directories:
  --bindir=DIR            user executables [EPREFIX/bin]
  --sbindir=DIR           system admin executables [EPREFIX/sbin]
  --libexecdir=DIR        program executables [EPREFIX/libexec]
  --sysconfdir=DIR        read-only single-machine data [PREFIX/etc]
  --sharedstatedir=DIR    modifiable architecture-independent data [PREFIX/com]
  --localstatedir=DIR     modifiable single-machine data [PREFIX/var]
  --runstatedir=DIR       modifiable per-process data [LOCALSTATEDIR/run]
  --libdir=DIR            object code libraries [EPREFIX/lib]
  --includedir=DIR        C header files [PREFIX/include]
  --oldincludedir=DIR     C header files for non-gcc [/usr/include]
  --datarootdir=DIR       read-only arch.-independent data root [PREFIX/share]
  --datadir=DIR           read-only architecture-independent data [DATAROOTDIR]
  --infodir=DIR           info documentation [DATAROOTDIR/info]

Optional Features:
  --disable-option-checking  ignore unrecognized --enable/--with options
  --disable-FEATURE       do not include FEATURE (same as --enable-FEATURE=no)
  --enable-FEATURE[=ARG]  include FEATURE [ARG=yes]
  --enable-stow           Enable stow-based install
  --enable-optional-subprojects
                          Enable all optional subprojects
  --enable-dual-endian    Enable support for running target in either
                          endianness

Optional Packages:
  --with-PACKAGE[=ARG]    use PACKAGE [ARG=yes]
  --without-PACKAGE       do not use PACKAGE (same as --with-PACKAGE=no)
  --with-boost[=ARG]      use Boost library from a standard location
                          (ARG=yes), from the specified location (ARG=<path>),
                          or disable it (ARG=no) [ARG=yes]
  --with-boost-libdir=LIB_DIR
                          Force given directory for boost libraries. Note that
                          this will override library path detection, so use
                          this parameter only if default library detection
                          fails and you know exactly where your boost
                          libraries are located.
  --with-boost-asio[=special-lib]
                          use the ASIO library from boost - it is possible to
                          specify a certain library for the linker e.g.
                          --with-boost-asio=boost_system-gcc41-mt-1_34
  --with-boost-regex[=special-lib]
                          use the Regex library from boost - it is possible to
                          specify a certain library for the linker e.g.
                          --with-boost-regex=boost_regex-gcc-mt-d-1_33_1
  --with-target=riscv64-unknown-elf
                          Sets the default target config

Some influential environment variables:
  CC          C compiler command
  CFLAGS      C compiler flags
  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
              nonstandard directory <lib dir>
  LIBS        libraries to pass to the linker, e.g. -l<library>
  CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
              you have headers in a nonstandard directory <include dir>
  CXX         C++ compiler command
  CXXFLAGS    C++ compiler flags
  STOW_ROOT   Root for non-native stow-based installs
  STOW_PREFIX Prefix for stow-based installs

Use these variables to override the choices made by 'configure' or to help
it to find libraries and programs with nonstandard names/locations.

#
# SYNOPSIS
#
#   AX_REQUIRE_DEFINED(MACRO)
#
# DESCRIPTION
#
#   AX_REQUIRE_DEFINED is a simple helper for making sure other macros have
#   been defined and thus are available for use.  This avoids random issues
#   where a macro isn't expanded.  Instead the configure script emits a
#   non-fatal:
#
#     ./configure: line 1673: AX_CFLAGS_WARN_ALL: command not found
#
#   It's like AC_REQUIRE except it doesn't expand the required macro.
#
#   Here's an example:
#
#     AX_REQUIRE_DEFINED([AX_CHECK_LINK_FLAG])

#      https://www.gnu.org/software/autoconf-archive/ax_append_flag.html
# ===========================================================================
#
# SYNOPSIS
#
#   AX_APPEND_FLAG(FLAG, [FLAGS-VARIABLE])
#
# DESCRIPTION
#
#   FLAG is appended to the FLAGS-VARIABLE shell variable, with a space
#   added in between.
#
#   If FLAGS-VARIABLE is not specified, the current language's flags (e.g.
#   CFLAGS) is used.  FLAGS-VARIABLE is not changed if it already contains
#   FLAG.  If FLAGS-VARIABLE is unset in the shell, it is set to exactly
#   FLAG.

# ===========================================================================
#
# SYNOPSIS
#
#   AX_CHECK_COMPILE_FLAG(FLAG, [ACTION-SUCCESS], [ACTION-FAILURE], [EXTRA-FLAGS], [INPUT])
#
# DESCRIPTION
#
#   Check whether the given FLAG works with the current language's compiler
#   or gives an error.  (Warnings, however, are ignored)
#
#   ACTION-SUCCESS/ACTION-FAILURE are shell commands to execute on
#   success/failure.
#
#   If EXTRA-FLAGS is defined, it is added to the current language's default
#   flags (e.g. CFLAGS) when the check is done.  The check is thus made with
#   the flags: "CFLAGS EXTRA-FLAGS FLAG".  This can for example be used to
#   force the compiler to issue an error when a bad flag is given.
#
#   INPUT gives an alternative input source to AC_COMPILE_IFELSE.
#
#   NOTE: Implementation based on AX_CFLAGS_GCC_OPTION. Please keep this
#   macro in sync with AX_CHECK_{PREPROC,LINK}_FLAG.

#
# DESCRIPTION
#
#   Check whether the given FLAG works with the linker or gives an error.
#   (Warnings, however, are ignored)
#
#   ACTION-SUCCESS/ACTION-FAILURE are shell commands to execute on
#   success/failure.
#
#   If EXTRA-FLAGS is defined, it is added to the linker's default flags

# SYNOPSIS
#
#   AX_APPEND_LINK_FLAGS([FLAG1 FLAG2 ...], [FLAGS-VARIABLE], [EXTRA-FLAGS], [INPUT])
#
# DESCRIPTION
#
#   For every FLAG1, FLAG2 it is checked whether the linker works with the
#   flag.  If it does, the flag is added FLAGS-VARIABLE
#
#   If FLAGS-VARIABLE is not specified, the linker's flags (LDFLAGS) is
#   used. During the check the flag is always added to the linker's flags.
#
#   If EXTRA-FLAGS is defined, it is added to the linker's default flags
#   when the check is done.  The check is thus made with the flags: "LDFLAGS
#   EXTRA-FLAGS FLAG".  This can for example be used to force the linker to
#   issue an error when a bad flag is given.
#
#   INPUT gives an alternative input source to AC_COMPILE_IFELSE.
#
#   NOTE: This macro depends on the AX_APPEND_FLAG and AX_CHECK_LINK_FLAG.
#   Please keep this macro in sync with AX_APPEND_COMPILE_FLAGS.
