Is there a single component in that directory ? There isn't, there are
only libraries in there.
The components are in /usr/local/orocos/lib/orocos

I must admit this is underdocumented...

Hi,

Find were liborocos-helloworld-gnulinux.so is install, that may look like /usr/local/lib/orocos. Provide this path in the RTT_COMPONENT_PATH. The Deployer load all the .so files in the folder provide in RTT_COMPONENT_PATH. Because the .so file you load doesn't contain the macro ORO_CREATE_COMPONENT(), the deployer can't load the dynamic libraries.
Your aborting kick-start is cause because HelloWorld component isn't a know component and not because /usr/local/orocos/lib/liborocos-deployment-gnulinux.so: not a valid component.

I hope this will help you!
