OK, I builded ogre_tools :) 1) download 1.7.1 sources 2) apply this patch: http://www.ogre3d.org/forums/viewtopic.php?f=5&t=59370 3) build the sources 4) copy the builded lib folder in ~/ros/stacks/visualization_common/ogre/ogre/ 5) rosmake ogre_tools Otherwise, when i try to build rviz it returns the following output: http://ros-users.122217.n3.nabble.com/file/n1835602/wxprogrig_build_output.log wxprogrig_build_output.log Gazebo instead returns the following output: http://ros-users.122217.n3.nabble.com/file/n1835602/gazebo_build_output.log gazebo_build_output.log How I can compile bullet in a way that it uses the double precision?
