Could not load library 'orocos-helloworld'þ

Submitted by nelton@skynet.be on Tue, 2008-09-30 11:20

Hi *,

i'm new to orocos. So I installed it, like it was explained on the website.
When I tried to execute the helloworld example I got these errors:

463.529 [ ERROR ][DeploymentComponent::loadLibrary] Could not load library 'orocos-helloworld':
463.530 [ ERROR ][DeploymentComponent::loadLibrary] orocos-helloworld.so: cannot open shared object file: No such file or directory
463.530 [ ERROR ][DeploymentComponent::loadLibrary] liborocos-helloworld.so: cannot open shared object file: No such file or directory
463.530 [ ERROR ][DeploymentComponent::loadLibrary] /usr/lib/liborocos-helloworld.so: cannot open shared object file: No such file or directory
false

Indicating that the orocos-helloworld library is missing.
Can I download this library from somewhere?

In what location did you install Orocos? What OS is this running on?
Might the library be outside your (dynamic) library path? More
information would be helpful.

Which version ? Prior to 1.6.0, this component was not compiled by default :-/
*and* the Debian packages did not contain it either...

So your best shot is to download/compile OCL 1.6.0 and run the example with
that version. If you run your deployer application, also check if
your 'ComponentPath' is set to where you installed the
liborocos-helloworld... libraries to.
