meta-ros/README.md

This is a layer to provide ROS Hydromedusa in an OpenEmbedded Linux system.
It provides a stable cross-compilation build system for many common ROS packages. 
Currently, this layer is still under continuous development.

## DEPENDENCIES ##

  This layer depends on:

  URI: git://git.openembedded.org/openembedded-core  
  branch: master  
  revision: HEAD  


  URI: git://git.openembedded.org/meta-openembedded  
  layers: meta-oe  
  branch: master  
  revision: HEAD  

 bitbake > 1.20

## DEPENDENCIES ON RECENT COMMITS ##

  Here, we list which parts of this layer depend on recent commits in the
  bitbake, openembedded-core and meta-openembedded repositories. Using
  `git blame` on the lines below, you can find the commits in meta-ros that
  rely on the remote commits. In case of porting to other versions, you must
  possibly revert some of those commits.

  cv-bridge and dependent recipes, e.g., the image-transport recipes, depend on
  7568bfdd114597956a1da68746f207ec7f93a48d@openembedded-core.
  
  Some recipes that need the Eigen library, e.g., the pcl-ros recipe, depend on
  424e3c1b930c0103c2cedfd4df1671e84a5256d5@meta-openembedded.

  Using wildcards in bbappend versions part in name depends on
  31bc9af9cd56e7b318924869970e850993fafc5f@bitbake and
  991cbeedbde8bd25ce08c669b1bfac8b99e33149@bitbake.

  octomap-ros and collada-urdf depend on
  43073569cb67d98c11aa71211d77b566b64f9145@openembedded-core and
  783fb88f476c94d5d4f4b954f7053464d9a6dff5@openembedded-core.

## INSTALLATION ##

  The repository contains a layer for ROS that builds on top of the
  OpenEmbedded Core layer and the meta-oe layer.

  We try our best to keep up with the development of the current HEAD
  of the layers mentioned above. If you notice any problems with the
  current HEAD, please report this in our issue tracker.

  You can use this layer with earlier versions of the layers mentioned above
  and their release branches, dora and daisy, with a few minor adjustments.
  The section "dependencies on recent commits" in this file provides a few
  pointers to adjust this layer for other versions.


## USAGE ##

  Currently, you can cross-compile the ROS packages with the commands:

    source oe-init-build-env
    bitbake <package-name>

  Look at the meta-ros test reports for the description of the current state.

  The recipe core-image-ros-roscore provides a minimal Linux system that runs
  roscore.

  You can compile the minimal Linux system with

    bitbake core-image-ros-roscore

  Then for example, you start this system in the qemu virtual machine with

    runqemu <MACHINE> core-image-ros-roscore

  
  On the Linux system, ensure that the own host's name in resolved by adding
  
    127.0.0.1	<HOSTNAME>.localdomain		<HOSTNAME>

  to the /etc/hosts file, and set up the environment with

    export ROS_ROOT=/usr
    export ROS_MASTER_URI=http://localhost:11311
    export CMAKE_PREFIX_PATH=/usr
    touch /usr/.catkin

  Finally, you can start roscore with

    roscore
