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.
