如何编译和安装Xenomai-forge到Linux系统（Fedora 14）

[rtems@silver build]$ ../configure -h  //配置脚本的情况
`configure' configures Xenomai 2.6.0 to adapt to many kinds of systems.

Usage: ../configure [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
                          [/usr/xenomai]
  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
                          [PREFIX]

By default, `make install' will install all the files in
`/usr/xenomai/bin', `/usr/xenomai/lib' etc.  You can specify
an installation prefix other than `/usr/xenomai' 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]
  --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]
  --localedir=DIR         locale-dependent data [DATAROOTDIR/locale]
  --mandir=DIR            man documentation [DATAROOTDIR/man]
  --docdir=DIR            documentation root [DATAROOTDIR/doc/xenomai]
  --htmldir=DIR           html documentation [DOCDIR]
  --dvidir=DIR            dvi documentation [DOCDIR]
  --pdfdir=DIR            pdf documentation [DOCDIR]
  --psdir=DIR             ps documentation [DOCDIR]

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-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]
  --disable-dependency-tracking  speeds up one-time build
  --enable-dependency-tracking   do not reject slow dependency extractors
  --enable-maintainer-mode  enable make rules and dependencies not useful
              (and sometimes confusing) to the casual installer
  --enable-shared[=PKGS]  build shared libraries [default=no]
  --enable-static[=PKGS]  build static libraries [default=yes]
  --enable-fast-install[=PKGS]
                          optimize for fast installation [default=yes]
  --disable-libtool-lock  avoid locking (might break parallel builds)
  --enable-debug          Enable debug mode in programs
  --enable-lores-clock    Enable low resolution clock
  --enable-clock-monotonic-raw
                          Use CLOCK_MONOTONIC_RAW for timings
  --enable-assert         Enable runtime assertions
  --enable-async-cancel   Enable asynchronous cancellation
  --enable-pshared        Enable shared multi-processing for capable skins
  --enable-registry       Export real-time objects to a registry
  --enable-smp            Enable SMP support
  --enable-x86-sep        Enable x86 SEP instructions for issuing syscalls
  --enable-arm-tsc        You only need this option if you get the following
                          message when starting an application: Xenomai:
                          incompatible feature set (userland requires
                          "kuser_tsc ...", kernel provides "...",
                          missing="kuser_tsc"). In that case, this option
                          allows to select the machine for which a user-space
                          tsc emulation should be generated. Valid machines
                          are at91, kuser, imx, ixp4xx, omap, orion, pxa,
                          s3c24x, sa1100.
  --enable-arm-quirks     Enable quirks for specific systems. Currently
                          supported quirks are for sa1100 and xscale3.
  --disable-doc-install   Do not install documentation
  --enable-dox-doc        Build Doxygen documentation
  --enable-dbx            Build Docbook XML documentation.
  --enable-dbx-network    Try to access Docbook DTD and XSL stylesheets
                          through network (default is to die if local
                          installation can not be found by configure).
  --enable-verbose-latex  Uses LaTeX non-stop mode
  --enable-posix-auto-mlockall
                          Enable Xenomai POSIX skin library to automatically
                          call mlockall at startup. This option is mainly
                          useful for running third-parties programs such as
                          the Open Posix Testsuite unmodified with Xenomai
                          POSIX skin
  --enable-dlopen-skins   Disable TLS features and automatic main thread
                          mapping by the POSIX skin to allows dlopen'ing
                          Xenomai libs.

Optional Packages:
  --with-PACKAGE[=ARG]    use PACKAGE [ARG=yes]
  --without-PACKAGE       do not use PACKAGE (same as --with-PACKAGE=no)
  --with-core=<cobalt | mercury>
                          build for dual kernel or single image
  --with-cc=compiler      use specific C compiler
  --with-pic              try to use only PIC/non-PIC objects [default=use
                          both]
  --with-gnu-ld           assume the C compiler uses GNU ld [default=no]
  --with-dbx-root         specify the Docbook XML root (that is, the directory
                          where docbookx.dtd should be found). Default is to
                          use well-known locations (or network if
                          --enable-dbx-network was passed).
  --with-dbx-xsl-root     specify the Docbook XML XSL stylesheet root. Default
                          is to use well-known locations (or network if
                          --enable-dbx-network was passed)
  --without-__thread      do not use TLS features
  --with-testdir=<test-binaries-dir>
                          location for test binaries (defaults to $bindir)

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>
  CPP         C preprocessor
  CCAS        assembler compiler command (defaults to CC)
  CCASFLAGS   assembler compiler flags (defaults to CFLAGS)

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