I am getting an error from the linker when I attempt to run catkin_make run_tests_my_package`

The error I get is: /usr/bin/ld: cannot find -lmy_package collect2: error: ld returned 1 exit status

Under testing in my CMakelist.txt I have the following: catkin_add_gtest(${PROJECT_NAME}-test test/utest.cpp) if(TARGET ${PROJECT_NAME}-test) target_link_libraries(${PROJECT_NAME}-test ${PROJECT_NAME}) endif()

include_directories(include ${catkin_INCLUDE_DIRS})

Am I missing something? do I need to use add_executable in my CMakelist.txt?

Another thing to mention is my workspace layout, it's arranged as follows: my_package/ bin/ build/ src/ my_class.h my_class.cpp test/ utest.cpp world/ CMakelist.txt

and inside utext.cpp I am referencing my_class.h list this #include "my_package/my_class.h

Yeah, I'm not actually including a cpp, was just a typo. I don't think I am creating a library called my_package in my CMakelist.txt. Here is the full CMakelist.txt

Wow... there's some unusual bits in there. If you're trying to write a test which tests the ActorLibrary, you should probably be linking it against the ActorLibrary in the same way that you link your primary executable.

Cool that seems to have worked, I've managed to build and the the tests by modifying the target_link_libraries to this target_link_libraries(${PROJECT_NAME}-test ActorLibrary ${catkin_LIBRARIES})
