unable to build qt gui packadges: catkin_make must be invoked in the root of workspace
Hi all,
Newbie to ROS, I have downloaded "qt_gui_core" under my "ros_ws" (/ros_ws/qt_gui_core/qt_gui_core) and complied with cmake ./CMakeLists.txt successfully. When I try to run catkin_make to build I get the error message: The specified base path "/ros_ws/qt_gui_core/qt_gui_core" contains a package but "catkin_make" must be invoked in the root of workspace.
What am I doing wrong? How is one supposed to compile these packages without a catkin_ws and under ros_ws? also, qt_gui_core contains many subdirectories (qt_dotgraph, qt_gui_cpp...) am I correct by assuming the get built if I successfully build qt_gui_core/qt_gui_core?
Thank you very much
