# xeno-config(1)

Display Xenomai libraries configuration

## NAME

xeno-config - Display Xenomai libraries configuration

## SYNOPSIS

**xeno-config**

**xeno-config** **--v** \| **--verbose**

**xeno-config --help**

**xeno-config** \[**--version**\] \[**--cc**\] \[**--arch**\] \[**--prefix**\] \[**--skin native\|posix\|psos\|rtdm\|uitron\|vrtx\|vxworks**\] \[**--cflags**\] \[**--ldflags**\] \[**--lib**\***-dir**\|**--library-dir**\|**--libdir**\|**--user-libdir**\]

## 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.
