Hi Ugo,

I indeed found the definition of the sdl dependency in
your_ros_path/stacks/common/rosdep.yaml
Here is the content of the file:
sdl:
  ubuntu: libsdl1.2-dev
  debian: libsdl1.2-dev
  fedora: SDL-devel
  arch: sdl 
  macports: libsdl 
sdl-image:
  ubuntu: libsdl-image1.2-dev
  debian: libsdl-image1.2-dev
  fedora: SDL_image-devel
  arch: sdl_image
  macports: libsdl_image
  gentoo: sdl-image
atlas:
  ubuntu: libatlas-base-dev
  debian: libatlas-base-dev
  arch: |
  macports: atlas
  gentoo: atlas

Checking synaptic confirms that libsdl1.2-dev is correctly installed on my
system.

Concerning the compilation question, yes, I compile everything using
rosmake.

rosmake opencv2 succeeds with no problem
rosmake -a fails only on ladybug2, no problem for the rest of the packages.

I must be doing something stupid here. Any idea?
