1. NAME

xeno-config - Display Xenomai libraries configuration

2. SYNOPSIS

xeno-config

xeno-config --v | --verbose

xeno-config --help

xeno-config [--version] [--cc] [--arch] [--prefix] [--xeno-cflags] [--xeno-ldflags] [--posix-cflags] [--posix-ldflags] [--lib-dir*|--library-dir|--libdir|--user-libdir]

3. 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.

4. 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.

--xeno-cflags

Outputs one line with the C compiler command-line options that are necessary to compile applications that use the Xenomai libraries.

--xeno-ldflags

Outputs one line with the C compiler command-line options that are necessary to link applications against the Xenomai libraries.

--posix-cflags

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

Outputs one line with the C compiler command-line options that are necessary to link applications against Xenomai’s Posix-compatible layer library.

--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.

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.
