\`configure' configures this package 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 \`..']

cat <<_ACEOF
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]
--datadir=DIR read-only architecture-independent data [PREFIX/share]
--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]
--libdir=DIR object code libraries [EPREFIX/lib]
--includedir=DIR C header files [PREFIX/include]
--oldincludedir=DIR C header files for non-gcc [/usr/include]
--infodir=DIR info documentation [PREFIX/info]
--mandir=DIR man documentation [PREFIX/man]

cat <<\_ACEOF
 
Program names:
--program-prefix=PREFIX prepend PREFIX to installed program names
--program-suffix=SUFFIX append SUFFIX to installed program names
--program-transform-name=PROGRAM run sed PROGRAM on installed program names
 
System types:
--build=BUILD configure for building on BUILD [guessed]
--host=HOST cross-compile to build programs to run on HOST [BUILD]
--target=TARGET configure for building compilers for TARGET [HOST]

Optional Features:
--disable-FEATURE do not include FEATURE (same as --enable-FEATURE=no)
--enable-FEATURE[=ARG] include FEATURE [ARG=yes]
--enable-maintainer-mode Enable developer functionality.
--enable-sim-bswap Use Host specific BSWAP instruction.
--enable-sim-cflags=opts Extra CFLAGS for use in building simulator
--enable-sim-debug=opts Enable debugging flags
--enable-sim-stdio Specify whether to use stdio for console input/output.
--enable-sim-trace=opts Enable tracing flags
--enable-sim-profile=opts Enable profiling flags
--enable-sim-inline=inlines Specify which functions should be inlined.
--enable-sim-alignment=align Specify strict, nonstrict or forced alignment of memory accesses.
--enable-sim-hostendian=end Specify host byte endian orientation.
--enable-build-warnings Enable build-time compiler warnings if gcc is used
--enable-gdb-build-warnings Enable SIM specific build-time compiler warnings if gcc is used
--enable-sim-hardware=LIST Specify the hardware to be included in the build.
 
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>
CPPFLAGS C/C++ preprocessor flags, e.g. -I<include dir> if you have
headers in a nonstandard directory <include dir>
CPP C preprocessor
 
Use these variables to override the choices made by `configure' or to help
it to find libraries and programs with nonstandard names/locations.

# intl sister-directory configuration rules.

# The idea behind this macro is that there's no need to repeat all the
# autoconf probes done by the intl directory - it's already done them
# for us. In fact, there's no need even to look at the cache for the
# answers. All we need to do is nab a few pieces of information.
# The intl directory is set up to make this easy, by generating a
# small file which can be sourced as a shell script; then we produce
# the necessary substitutions and definitions for this directory.
 
 
 
 
 
 
 
# Bugs in autoconf 2.59 break the call to SIM_AC_COMMON, hack around
# it by inlining the macro's contents.
# This file contains common code used by all simulators.
#
# common.m4 invokes AC macros used by all simulators and by the common
# directory. It is intended to be included before any target specific
# stuff. SIM_AC_OUTPUT is a cover function to AC_OUTPUT to generate
# the Makefile. It is intended to be invoked last.
#
# The simulator's configure.in should look like:
#
# dnl Process this file with autoconf to produce a configure script.
