Hi i want to work with ptam,

the problem is, that i can't build it. I followed the instructions but i have some problems: Rosdep:

rosdep install ptam
ERROR: the following packages/stacks could not have their rosdep keys resolved
to system dependencies:
ptam: Cannot locate rosdep definition for [ptam_com]

rosmake:

rosmake ethzasl_ptam

So i thought i could compile manually by using make in the main folder. It runs for ~ 5mins and then exits with following error:

CMake Error at /opt/ros/groovy/share/catkin/cmake/catkinConfig.cmake:72 (find_package):
  Could not find a configuration file for package ptam_com.

  Set ptam_com_DIR to the directory containing a CMake configuration file for
  ptam_com.  The file will have one of the following names:

    ptam_comConfig.cmake
    ptam_com-config.cmake

I use hydro but since ptam doesn't support hydro i installed groovy and changed the "source" in the .bashrc. $ROSPACKAGEPATH is

/opt/ros/groovy/share:/opt/ros/groovy/stacks:/home/gerken/ROS/pkg/ethzasl_ptam

Could anybody help me with building the package? Thanks Andreas
