Hi, I've just installed ros from the pre-compiled packages, and I see the binary packages depend on a lot of -dev packages, automake, autoconf, etc... Is there a rationale behind that? I would believe that one of the advantages of pre-compiled binaries is that it make it easier to install ros on an embedded system, with limited hard-drive/flash space, all of which get lost if the ros packages pull close to 1GB of dependencies. How much community interest would there be behind separating the packages into binary and -dev packages, the binary having very limited dependencies? Otherwise, the install from source can be compiled and deployed within 200MB, incl. roscore (roscpp, rospy), opencv, and image pipeline, laser pipeline, laser drivers, but no tf (brings in bullet and a lot of friends) and no rviz.
