In the instructions, it is not clear how I edit the CMakefile.txt to add files to the project (http://wiki.ros.org/catkin/Tutorials/using_a_workspace)
$ cd ~/catkin_ws/src/beginner_tutorials/src # Add/Edit source files $ cd ~/catkin_ws/src/beginner_tutorials # Update CMakeFiles.txt to reflect any changes to your sources $ cd ~/catkin_ws $ catkin_make
You have to be more specific. What files do you want to add? If it's a library that your code depend on then,
add_library(SOURCE_LIB src/some_lib_source.c)
target_link_libraries(SOURCE_LIB ${catkin_LIBRARIES})
now you can add SOURCE_LIB to link it with your code
target_link_libraries(your_node ${catkin_LIBRARIES} SOURCE_LIB)
Actually your answer illustrates part of the problem. I wanted to add another source file, but I assume the instructions would differ depending on the type of file that one wanted to add. Perahps that guide is assuming a level of understanding of cmake that is not "beginner"? BTW - I assumed (C++ programmer background) that a source file is source code, as in a cpp file. For now I am ignoring the packaging stuff and moving on with example_node, assuming that clarity will emerge later.
Yes, it would help if you had just a bit more of cmake understanding, such as by doing this tutorial (http://web.cs.swarthmore.edu/~adanner/tips/cmake.php). Some explanations also here: (http://wiki.ros.org/catkin/CMakeLists.txt)
Thank you, I will use catkin going forward. The tutorial using rosbuild is here <http://wiki.ros.org/ROSNodeTutorialC%2B%2B> (at least I think it uses rosbuild - it lacks a package.xml file).
