Hi, CTurtle is now successfully installed on Mac OS X 10.6, but I am unable to get Ogre working, so no nav_view/ rviz. First of all, following the installation procedure for the OGRE framework with OGRE 1.7.1 fails here: sudo cp -r /Volumes/OgreSDK/OgreSDK/Dependencies/*.framework /Library/Frameworks because the dependences directory cannot be found. I couldn't find it anywhere else in the distribution either. So I tried using 1.6.5. I installed the framework, then tried rosmake ogre_tools It came agonizingly close to building, but failed near the end. The error log is attached below. Also btw, rosdep install ogre_tools was unable to use macports to install nvidia-cg, however I was able to ignore this on my previous installation of box_turtle on 10.5. Any suggestions? ~Deepak $rosmake ogre_tools -- Installing: /Users/Deepak/ros/stacks/visualization_common/ogre/ogre/include/OGRE/Threading/OgreDefaultWorkQueueStandard.h CMake Error at RenderSystems/GL/cmake_install.cmake:44 (FILE): file INSTALL cannot find "/Users/Deepak/ros/stacks/visualization_common/ogre/build/ogre_src_v1-7-1/build/lib/RelWithDebInfo/RenderSystem_GL.dylib".
