Hi,

I'm a bit lost with the integration of Qt with ROS. I have to make a few custom interfaces for my university project (a nifty robot that do cool stuff) and I was thinking about using Qt to make them since we already have a lot of experience with Qt C++ in my team.

The problem is, my workspace is using catkin and the package qt_ros (with the node roscreate-qt-pkg) seems to create files that are made for rosbuilder. By example, it create a manifest.xml (wich I think is deprecated in groovy) and the CMakeLists.txt is really different from the ones I get from catkin-package. So, my node is not built at all when I execute catkin_make. How am I suppose to do it?

I really like ROS and all his tools, but if I can't create my interfaces quickly we will have to switch to another technology or think about an alternative to talk to ROS from another application that contains our interface : (.

Hi, I have a problem with catkin_make that stop me from building my project. He seems to compile my c++ file before generating my message and service.

In bold, wecan see that he can't find my service StartKinocto.h that doesnt exist because it havent been generated first... If I comment the code that use this service the service file is generated after Kinocto.cpp :

Is that normal? What should I do?

One of my teamates can't compile our school project. The catkin_make command give this error :

ImportError: "from catkin_pkg.topological_order import topological_order" failed: No module named catkin_pkg.packages
Make sure that you have installed "catkin_pkg", it is up to date and on the PYTHONPATH.

We compared our PYTHONPATH and we have the same :

/opt/ros/groovy/lib/python2.7/dist-packages

We tried to reinstall ROS completely, but it doesn't work even after that.

Any suggestion to fix this?
