I am using git version 1.6.3.3 I just tried "rosmake RCPRG_laser_drivers" from the RCPRG_laser_drivers directory with the same result as before. Doing "sudo git clone http://github.com/konradb3/libLMS1xx.git build/libLMS1xx" worked without errors, but when I try to run rosmake again after that, it still has the error. I am able to run mkdir without errors. -- View this message in context: http://ros-users.122217.n3.nabble.com/Ros-Node-for-Sick-LMS-100-tp1268551p2065225.html Sent from the ROS-Users mailing list archive at Nabble.com.
