Hey Joachim, I had that error at first. There should be a following example command that shows you how to download it. There's about 15 or so libraries that can't be found (but they can be installed). Stick through it, and eventually you'll be able to try to rosmake stuff. :) Hope that helps, EK On 2010-03-24, at 12:02 AM, Joachim Bean wrote: > Hi, > I have ROS running on Snow Leopard, but I can't compile a project because I'm getting a "ld: library not found for -llog4cxx" error.
