Dear orocos users

Sorry for the repeat post.

I am just starting to use orocos rtt. I check it out from the source which comes from http://wiki.ros.org/rtt?distro=groovy use command git clone https://git.gitorious.org/orocos-toolchain/orocos_toolchain.git then I get the file structure like (in orocos_toolchains) CMakeLists.txt env.sh Makefile orocos_toolchain rtt stack.xml utilmm env.mk log4cpp ocl orogen rtt_typelib typelib utilrb

The problem is that I found the all folders almost empty. e.g. rtt folder is empty, no any file.

When I use catkin_make this folder, there is no any building result. I am not quite sure whether I am right. or maybe there are intall tutorial

If you have any comment, please let me know.
