Technical Field

Background
With the rapid development of the electronic industry and the IT industry, the UI application and the human-computer interaction friendliness in the development of an embedded system play more and more important roles. The Qt is used as a cross-platform graphical user interface application program development framework, and is more and more widely applied.
In the embedded field with higher real-time requirement, a VxWorks operating system is generally adopted, and because the VxWorks operating system is relatively closed, no Qt integrated development environment aiming at the VxWorks operating system exists, so that the Qt application developed in other operating system platforms is transplanted to the VxWorks operating system, and the greatest problem is the debugging problem. At present, the basic debugging means is to add printout and develop third-party plug-ins. The first method needs to add a printing output code in a source program, so that not only is the fault positioning process complicated, but also the fault positioning is restricted by the hardware environment of an output terminal; the second method has high development cost, low universality and low application range.
In order to solve the current situation, a QtCreator compiling and connecting process is researched, starting from the principle of cross compiling of a VxWorks operating system and Qt, a tool in Qt software installed under a windows operating system is used for generating a file which can be compiled in the VxWorks operating system, and therefore the method for debugging under the VxWorks development environment is achieved.
