80 CHAPTER 3. LANGUAGE HDevelop / 2000-11-16
Chapter 4 Code Generation The idea of code generation is as follows: After developing a program according to the given requirements it has to be translated into its final environment. Here, you often don’t want to use HDevelop to save memory or disk space. In addition, the program should execute as fast as possible, especially without the overhead of an interpreter. Therefore, the program is transfered into another programming language that can be compiled and allows a faster execution. In addition to this, features of the new environment like special libraries or graphical user interface builder can thus be used. HDevelop allows to “export” a developed HDevelop program to the programming languages C++, Visual Basic, and C, by writing the corresponding code to a file. The sections 4.1, 4.2, and 4.3 describe the general steps of program development using this feature for the three languages, including some language-specific details of the code generation and optimization aspects. Because HDevelop does more than just execute a HALCON program, the behavior of an exported program will differ in some points from its HDevelop counterpart. A prominent example is that in HDevelop, all results are automatically displayed, while in the exported programs you have to insert the corresponding display operators explicitely. Section 4.4 describes these differences in more detail. 4.1 Code Generation for C++ This section describes how to create a HALCON application in C++, starting from a program developed in HDevelop. 4.1.1 Basic Steps 4.1.1.1 Program Export The first step is to export the program using the menu Ð º ËÚ ×. Here, select the language (C++) and save it to file. In UNIX you specify the language by giving the file the extension “ºÔÔ”. A file will be created that contains the HDevelop program as C++ source code in a procedure ØÓÒ´µ. This procedure is called in function ÑÒ´µ. Besides the program code, the file contains all necessary ÒÐÙ instructions. All variables (iconic as well as control) 81
