RTT PluginLoader fails to load rtt_ros_transport plugin

[dmronga]

Hi,

I get the following error when using the rock-ros-bridge in combination with orocos_cpp:

4.015 [ ERROR ][OrbRunner] Not a plugin: /home/dennis/rock/install/lib/orocos/gnulinux/types/librtt-transport-ros-gnulinux.so: undefined symbol: loadRTTPlugin

The message comes from here. It seems that when the RTT plugin loader calls loadPlugins() or loadTypekits() (which is done by orocos_cpp, see here), it scans certain directories for plugins and throws an exception when a plugin cannot be loaded. In this case it misses the implementation of 'loadRTTPlugin' for librtt-transport-ros-gnulinux.so which is installed in install/lib/orocos/gnulinux/types in my case.

I am on rock master, ubuntu16.04 and use this fork of rtt_ros_transport.

Is this a problem of orocos_cpp or the implementation of rtt_ros_transport?
