Building a Xenomai Runtime Package

This howto describes building the xenomai-runtime package from git.

The Xenomai runtime package is needed by the Xenomai threads versions of LinuxCNC (xenomai-kernel and xenomai-user). See this page for more info: XenomaiKernel

This recipe was developed on Ubuntu Precise, amd64 arch, but will probably work for other versions of Debian-like distros and other arches.

This builds either the master branch or a release. As of this writing, debian package building is broken in v2.6.2, but fixed in master.

Prerequisites

Set variables needed for the build

Adjust the following values according to your needs.

 # Version of xenomai release to use.  Stable versions listed here:
 # http://download.gna.org/xenomai/stable/
 XENO_VERSION=2.6.2.1

 # Xenomai package release; this should be bumped with each new package release,
 # and reset with each new upstream Xenomai version
 PKG_RELEASE=1.0

 # Your name and email for the changelog
 FULLNAME="John Doe"
 EMAIL="jdoe@example.com"

install prerequisite packages

This list may be incomplete; git-buildpackage will print a list if more are needed.

Build xenomai

 # unpack the archive
 tar xjf xenomai-$XENO_VERSION.tar.bz2 && cd xenomai-$XENO_VERSION

 # update changelog
