This is a layer to provide ROS Indigo Igloo 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 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.
|
|
For native python-numpy support, these recipes also depend on
|
|
c13c5f40160d289bb62538a16900fed30621cb22@meta-openembedded or on
|
|
9bf355cceaec6ebacdcbcc35f9713ff73e1c85da@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.
|
|
|
|
urdfdom-py depends on the meta-python layer since
|
|
a6d7ba92645a112af358efd94ff3aa0c74985a51@meta-openembedded.
|
|
|
|
Since 3edf08b38b0af93cef0933b061349264dc86d54c@openembedded-core,
|
|
recipes relying on opencv need to activate the DISTRO\_FEATURE
|
|
opengl.
|
|
|
|
rosbridge-library depends on python-six, which is provided in meta-python
|
|
since a36869c700bed940f7f0aa4b9703ae630dc84eac@meta-openembedded.
|
|
|
|
## 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 ##
|
|
|
|
Initialize the build environment:
|
|
|
|
source oe-init-build-env
|
|
|
|
Add the required layers (see **DEPENDENCIES**) by modifying ``./conf/bblayers.conf`` (adjust ``/home/me/devel`` as necessary):
|
|
|
|
BBLAYERS ?= " \
|
|
/home/me/devel/openembedded-core/meta \
|
|
/home/me/devel/meta-openembedded/meta-oe \
|
|
/home/me/devel/meta-openembedded/meta-python \
|
|
/home/me/devel/meta-openembedded/meta-multimedia \
|
|
/home/me/devel/meta-ros \
|
|
"
|
|
|
|
Compile package:
|
|
|
|
bitbake <package-name>
|
|
|
|
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=/opt/ros
|
|
export ROS_DISTRO=indigo
|
|
export ROS_PACKAGE_PATH=/opt/ros/indigo/share
|
|
export PATH=$PATH:/opt/ros/indigo/bin
|
|
export LD_LIBRARY_PATH=/opt/ros/indigo/lib
|
|
export PYTHONPATH=/opt/ros/indigo/lib/python2.7/site-packages
|
|
export ROS_MASTER_URI=http://localhost:11311
|
|
export CMAKE_PREFIX_PATH=/opt/ros/indigo
|
|
touch /opt/ros/indigo/.catkin
|
|
|
|
Finally, you can start roscore with
|
|
|
|
roscore
|
|
|
|
If you want to use the roswtf utility for diagnostics and experience an
|
|
exception like
|
|
|
|
rospkg.os_detect.OsNotDetected: Could not detect OS, tried ['windows', 'ubuntu', 'slackware', 'rhel', 'qnx', 'osx', 'opensuse', 'opensuse', 'mint', 'linaro', 'gentoo', 'funtoo', 'freebsd', 'fedora', 'elementary', 'debian', 'cygwin', 'centos', 'arch']
|
|
|
|
then you need to set `ROS_OS_OVERRIDE` to one of the listed OS names, e.g.
|
|
|
|
export ROS_OS_OVERRIDE=ubuntu
|
|
|
|
And since Yocto-based distributions are not supported by the `rospkg`
|
|
library you have to interpret roswtf's output by translating Ubuntu
|
|
package names manually to their corresponding package/recipe names that
|
|
were chosen in the meta-ros layer.
|
|
|
|
|
|
## CROSS-COMPILING ALL ROS PACKAGES IN meta-ros
|
|
|
|
The meta-ros layers only includes a subset of the officially released ROS
|
|
packages, available from packages.ros.org. The here provided ROS packages
|
|
are mainly driven by the current users' needs.
|
|
|
|
For ROS packages that depend on cv-bridge, the commercial license flag
|
|
must be whitelisted, as cv-bridge depends on opencv, and opencv by
|
|
default depends on libav that has special terms and conditions when used
|
|
commercially.
|
|
This can be done by adding to the local.conf the line:
|
|
|
|
LICENSE_FLAGS_WHITELIST = "commercial"
|
|
|
|
Alternatively, the dependency from opencv on libav can be explicit excluded
|
|
by modifying the PACKAGECONFIG setting.
