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]
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.
--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.
