I'm trying to install vslam with cturtle via the instructions here: http://www.ros.org/wiki/vslam and I ran into a few problems. First, the unstable version of pcl is not compiling. text here: http://people.csail.mit.edu/garratt/makelogs/pclmakelog.txt Anyway, I switched to using tags/perception_pcl-0.8.0/ Then sba fails, also complaining about eigen. So I switched it to tags/vslam-0.2.2 and it compiles. It seems as though we need to start creating cturtle/diamondback install pages, which give the appropriately tagged versions. I just had to do this for my packages: http://www.ros.org/wiki/mit-ros-pkg/KinectDemos#Software_Setup I even nabbed the appropriate pictures... Garratt
