If you are talking about compiler warnings, you can pass arguments to cmake or make via catkin_make:

 $ catkin_make --cmake-args -DCMAKE_CXX_FLAGS="-Wall"

Should enable all the warnings, for example.

That should have been `CMAKE_CXX_FLAGS`, I updated my answer.

Additionally to what William said.

Usually you get warnings only on the first run of catkin_make. Once the piece of code is compiled, catkin_make (actually cmake) will not attempt to compile it again and thus you will not see the warnings. To force rebuild simply delete the build tree (build directory).

yes true, but my warning level is to low so i get less warnings
