DESCRIPTION

       xeno-config is a script that is used to to display the compiler and linker flags that are
       required for building applications that use Xenomai. Any combination of options can be
       chosen (except --verbose and --help) to display configuration information, and options can
       be given in any order. The command output one line for each option, in the same order as
       the options.

       When xeno-config --verbose is executed, all configuration information is displayed in a
       different, more human-readable format.

       When xeno-config is executed without any options, the output is equivalent to than when
       executing xeno-config --verbose then xeno-config --help.

OPTIONS

       --v, --verbose
           Outputs all configuration information, in a human-readable format.

       --help
           Outputs the list of available command-line options.

       --version
           Outputs one line with the installed Xenomai version.

       --cc
           Outputs one line with the path to the C compiler command that was used to compiled
           Xenomai.

       --arch
           Outputs one line with the architecture to compile to, e.g. i386. May be different from
           the architecture of the currently running system, if cross-compiling.

       --prefix
           Outputs one line with the absolute path to the base Xenomai installation directory.

       --skin
           Choose the skin for which xeno-config should print the compilation flags.

       --cflags
           Outputs one line with the C compiler command-line options that are necessary to
           compile applications that use the Xenomai skin passed to the --skin option.

       --ldflags
           Outputs one line with the C compiler command-line options that are necessary to link
           applications that use the Xenomai skin passed to the --skin option with the necessary
           libraries.

       --lib*-dir, --library-dir, --libdir, --user-libdir
           Outputs one line with the absolute path to Xenomai’s libraries. In the --lib*-dir
           option name, the * is meant as a wildcard: --lib-dir, --libfoo-dir and --libbar-dir
           are all valid and synonymous options.

DEPRECATED OPTIONS

       --xeno-cflags
           This option is deprecated, please use --skin and --cflags instead. Outputs one line
           with the C compiler command-line options that are necessary to compile applications
           that use any Xenomai skin, except the posix skin.

       --xeno-ldflags
           This option is deprecated, please use --skin and --ldflags instead. Outputs one line
           with the C compiler command-line options that are necessary to link applications that
           use any Xenomai skin, except the posix skin, with the necessary libraries. Note that
           the particular -llibskin flag should be added to the flags returned by this option.

       --posix-cflags
           This option is deprecated, please use --skin posix --cflags instead. Outputs one line
           with the C compiler command-line options that are necessary to compile applications
           that use Xenomai’s Posix-compatible layer library.

       --posix-ldflags
           This option is deprecated, please use --skin posix --ldflags instead. Outputs one line
           with the C compiler command-line options that are necessary to link applications
           against Xenomai’s Posix-compatible layer library.

ENVIRONMENT VARIABLES

       DESTDIR
           If the DESTDIR variable is set, its content is prepended to the Xenomai installed
           directories and files names output by the --prefix and --library-dir options, and to
           the Xenomai installation directories in the flags output by the --xeno-cflags,
           --xeno-ldflags, --posix-cflags, --posix-ldflags options.

       If DESTDIR was set when compiling and installing Xenomai, e.g. for cross-compilation,
       DESTDIR must be set to the same value before calling xeno-config, in order to output valid
       directory and file names.

RETURN CODES

       0
           Successful script execution.

       1
           The --posix-ldflags option has been given but Posix support is not available in
           Xenomai; or an invalid argument has been given on the command-line.
