Using Threading Building Blocks with ROS

Hi,

I couldn't find any information about how to use ROS with Threading Building Blocks (TBB). If I add

<rosdep name="tbb" />

to my manifest.xml and do "rosdep install" I get the error "Failed to find rosdep tbb for package ... on OS:ubuntu version:natty". Do I have to create my own rosdep.yaml file? I'm working with ROS Electric on Ubuntu Natty.

Thanks for your help!

This is confusing, because rosdep changed significantly between Electric and Fuerte.

On Fuerte it resolves to libtbb-dev.
On Electric, it needs to be defined in some stack's rosdep.yaml.

What does this show?

$ rosdep where_defined tbb

UPDATE: your result shows that tbb is not defined by any stack in your $ROS_PACKAGE_PATH.

If you are developing a stack of your own, add a rosdep.yaml containing something like this stanza:

tbb:
  arch: intel-tbb
  ubuntu: libtbb-dev
  fedora: tbb-devel

the output is:

$ rosdep where_defined tbb
tbb defined in set([])

thanks, this works :)

Finally, I had to add a command to link against tbb to my CMakeLists.txt:

target_link_libraries(mynode tbb)

You get that error because Threading Building Blocks is not part of ROS (as far as I can tell). Try implementing it in your code like you normally would (you may need to change some CMake configuration).
