What is the purpose of the Makefile? Are you trying to do a hybrid package that can be compiled using both CMak/catkin & make? Catkin pkgs don't use/have a Makefile.

Also:

[..] With $ make grampc in - catkin/src i get: [..]

Unless you are really doing some hybrid thing, I wouldn't do that. This doesn't look like a normal cmake / catkin workflow to me.

From what I can gather from your OP:

1. remove grampc/Makefile
2. remove any other 'left overs' from your previous build attempts in the src dir
3. cd /path/to/catkin/
4. catkin_make -j1

Now see whether you get any more errors, and try to solve them.

The -j1 is just for debugging your build infrastructure, it disables parallel building, which can get confusing when trying to fix things.

Edit:

Try something like this. I've assumed there is something called grampc_node.cpp, as it seems like you are trying to create a ROS node, that uses libgrampc to do something. If not (and this is a library-only pkg), just remove the add_executable(..) (and associated target_link_libraries(..)) statement.

In general, you'll want to link against ${catkin_LIBRARIES}, which will contain all libraries exported by the packages that you specify in your find_package(catkin REQUIRED COMPONENTS ..) statement. You were only linking roscpp, hence the linker errors about rosbag fi.
