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.
