xeno-config [--version] [--cc]
[--arch] [--prefix] [--skin

[--ldflags]
[--lib*-dir|--library-dir|--libdir|--user-libdir]
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.
