Hi Carlos,

it seems like you did not link to the RTT scripting plugin, which is
required to use the scripting API in C++.

CMake example:

find_package(OROCOS-RTT REQUIRED COMPONENTS* rtt-scripting*)
include(${OROCOS-RTT_USE_FILE_PATH}/UseOROCOS-RTT.cmake)

orocos_component(component ...)
target_link_libraries(component *${OROCOS-RTT_RTT-SCRIPTING_LIBRARY}*)

For more details, see
http://www.orocos.org/wiki/orocos/toolchain/getting-started/cmake-and-bu...
.

Cheers,
Johannes
