Hi, when I add a package dependency in my stack.xml file, rosdep complains about it not having the 'stack' attribute: $ rosdep check orocos [rosstack] bad depend syntax (no 'stack' attribute) in [/home/steven/src/svn/robotics-ros/install/orocos/stack.xml] [rosstack] invalid manifest ... where the stack.xml file contains: Can a stack only depend on another stack and not on packages? I'm working with boxturtle. regards, Steven
