I am new to orocos and as I was going through the deployment exercise which is in rtt_1.12 examples I have an error output like this when running the example
In Task Deployer[R]. (Status of last Command : none )
(type 'ls' for context info) :loadComponents("example.cpf")
Got :loadComponents("example.cpf")
12.757 [ Info ][DeploymentComponent::loadComponents] Loading 'example.cpf'.
12.796 [ Info ][DeploymentComponent::loadComponents] Validating new configuration...
12.797 [ Info ][DeploymentComponent::import] Importing component libraries from directory ./. ...
12.797 [ Info ][DeploymentComponent::import] Loaded regular library ././libplant.so.
12.797 [ Info ][DeploymentComponent::import] NOTE: loading regular libraries is unavailable in RTT 2.x.
12.798 [ Info ][DeploymentComponent::import] Loaded regular library ././libcontroller.so.
It looks like I cant load the components.
any help is appreciated.

There is no _error_ message in your posted output, all messages are
info messages which indicate all is going well. However, from that
output, it looks like you are using the orocos_toolchain (which is
v2.x) with the rtt exercises v1.x. The toolchain comes with new
exercises according to the 2.x syntax, and they are available at
https://github.com/psoetens/orocos-rtt-examples in the
rtt-2.0-examples branch.
How did you install the toolchain?

Steven

Re: Orocos Deployment
I am using Ubuntu 10.04 and installed RTT v1.12 and OCL v1.12 following the instructions at the page
http://www.orocos.org/stable/documentation/rtt/v1.12.x/doc-xml/orocos-installation.html
I wanted to make a new component library and test it with a deployer. What I did was change the class name in HelloWorld deployment exercise to HelloWorldMT and wanted to see if the deployer can detect the new library. Then i used displayComponentTypes() hoping to see the OCL::HelloWorldMT as a component but it is not there.
where did i do wrong? regards Meti

For starters, if you're a new user, it's strongly advised to use RTT 2.2 or
later (included in Orocos Toolchain 2.2) here: http://www.orocos.org/toolchain
If you have to use the 1.12 versions (we'd be interested why), then start your
deployer with:
deployer-gnulinux -ldebug
Which will show where it looked for components. You can add a directory to
search for components by using the import("/path/to/lib/orocos") which will
scan that directory for new component libraries, then it should show up in
displayComponentTypes(). You can for example point the import statement to
your build/helloworld directory.

or, if you happen to work with ROS: http://www.ros.org/wiki/orocos_toolchain_ros
which is the same software, but available in the ROS framework.

I linked only orocos-rtt and it worked. But since i dont have a problem with upgrading to v2.2 I decided to do it and follow Stevens way because I also use ROS. I installed the package but are rtt, ocl and kdl also installed? I expect the installation to put the rtt and ocl header and libraries in /usr or /usr local.
Did you install from the package manager or from git?
Either way, the ros-*-orocos_toolchain_ros stack contains (as listed
on the wiki page) all of the orocos toolchain (that includes rtt and
ocl) + integration packages for ROS. There however will be no files
installed outside the stack folder. All header files or libraries go
into PackageName/install/*... or PackageName/lib directories - just
like with all other ROS packages.
For KDL:
- there is a kdl version in the geometry stack
- or you can check out directly
http://git.mech.kuleuven.be/orocos_kinematics_dynamics.git

I figured out the problem it was because I was linking all the ocl libraries while making the component library and it was reading it as a multi component library. I linked only orocos-rtt and it worked. But since i dont have a problem with upgrading to v2.2 I decided to do it and follow Stevens way because I also use ROS.
