import catkin workspace to qtcreator

edit

Hi,

I am trying to program a GUI for ROS using qtcreator.

Therefore I have created an empty package using "catkin_create_qt_pkg gcs_gui". Afterwards I ran "catkin_make" to build the new package. It is running by "rosrun gcs_gui gcs_gui".

I would like to edit the files with Qtcreator now but it seems I am missing step during setup. I followed this http://wiki.ros.org/IDEs#QtCreator by

• copying CMakeLists.txt the way it said
• run qtcreator
• open CMakeLists.txt file (I get the error below)
  • SOFT ASSERT: "!tcd.tcs.isEmpty()" in file /work/build/qt-creator/src/plugins/cmakeprojectmanager/cmakeprojectimporter.cpp, line 336)
• build directory is already selected correctly
• I don't understand this step: ... and 'Run CMake': Where should I run that? What do I need to type where?
• If I just click configure project, I get this:
  • /home/vinni/catkin_ws/src/CMakeLists.txt:59: CMake Error (message): find_package(catkin) failed. catkin was neither found in the workspace nor in the CMAKE_PREFIX_PATH. One reason may be that no ROS setup.sh was sourced before.
  • Configuring incomplete, errors occurred!
  • cmake process exited with exit code 1.

Also, if I add this to the CMakeLists.txt, it fails as well:

• DCMAKE_INSTALL_PREFIX=/home/vinni/catkin_ws/install
• DCATKIN_DEVEL_PREFIX=/home/vinni/catkin_ws/devel

I hope someone can help me. I am a fairly newbie with ROS. Thank you, Vincenz
