How to link a nodelet to external libraries?
I'm trying to use a nodelet with an external library. But when running the nodelet, it obviously complaints that it can't find some symbol which is in this external library.
I can link the regular node the library without problems. However, when I use the nodelet version, it complains. I'm certain that I'm not linking the nodelet to the library. I don't know how to.
If you know how to link a nodelet to an external library, please share your know-how-to.
The proposed SOLUTION in CMakeLists.txt relevant piece looks like the following:
set(MVIMPACT_LIBRARIES mvDeviceManager)
# Nodelet:
rosbuild_add_library(mv_bluefox_driver_nodelet src/nodelets.cpp src/camera.cpp)
# Linking the nodelet to the mvDeviceManager library
target_link_libraries(mv_bluefox_driver_nodelet ${MVIMPACT_LIBRARIES})
# Regular Node:
rosbuild_add_executable(camera_node src/camera_node.cpp src/camera.cpp)
target_link_libraries(camera_node ${MVIMPACT_LIBRARIES})
Comments
Please show snippets of your CMakeLists.txt for both the node and the nodelet versions. That should help diagnose your problem.

Compile time problem or runtime problem?

Runtime problem with the error pointing at some function (DMR_Init) from the external library as: symbol lookup error: /DIR_TO_MY_PACKAGE/mv_bluefox_driver/lib/libmv_bluefox_driver_nodelet.so: undefined symbol: DMR_Init
