82 CHAPTER 4. CODE GENERATION are declared locally in the procedure ØÓÒ´µ. Iconic variables belong to the class ÀÓØ and all other variables belong to ÀÌÙÔÐ. 4.1.1.2 Compiling and Linking in Windows NT or Windows 2000 Environments The next step is to compile and link this new program. In the Windows NT environment, Visual C++ is used for the compiling and linking. Example projects can be found in the directory ±ÀÄÇÆÊÇÇÌ±ÒÜÑÔÐ×ÒÔÔÒ¹ÒØ. If you want to use Parallel HALCON, you have to include the libraries ÔÖÐÓÒºÐ»ºÐÐ and ÔÖÐÓÒÔÔºÐ»ºÐÐ instead of ÐÓÒºÐ»ºÐÐ and ÐÓÒÔÔºÐ»ºÐÐ in your project (see the HALCON/C++ User’s Manual for more details). 4.1.1.3 Compiling and Linking in UNIX Environments To compile and link the new program (called e.g. Ø×ØºÔÔ) in the case of UNIX, you can use the example ÑÐ which can be found in the directory °ÀÄÇÆÊÇÇÌ»ÜÑÔÐ×»ÔÔ by calling Ñ ÌËÌÈÊÇØ×Ø Alternatively, you can set the variable ÌËÌ ÈÊÇ in ÑÐ to Ø×Ø and then just type Ñ. You can link the program to the Parallel HALCON libraries by calling Ñ ÔÖÐÐÐ ÌËÌÈÊÇØ×Ø or just type Ñ ÔÖÐÐÐ if you set the variable ÌËÌ ÈÊÇ as described above. For more details see the HALCON/C++ User’s Manual. 4.1.2 Optimization Optimization might be necessary for variables of class ÀÌÙÔÐ. This kind of optimization can either be done in HDevelop or in the generated C++ code. In most cases optimization is not necessary if you program according to the following rules. 1. Using the tuple concatenation, it is more efficient to extend a tuple at the “right” side, like: Ì Ì¸ÆÛ℄ because this can the transformed to ÌºÔÔÒ´ÆÛµ in C++ and requires no creation of a new tuple, whereas HDevelop / 2000-11-16
4.1. CODE GENERATION FOR C++ 83 Ì ÆÛ¸Ì℄ which is translated into Ì ÆÛºÔÔÒ´Ìµ would need the creation of a new tuple. 2. Another good way to modify a tuple is the operator Ò×ÖØ (see section 3.5.2). In this case HDevelop code like Ì℄ ÆÛ can directly be translated into the efficient and similar looking code Ì℄ ÆÛ 4.1.3 Used Classes There are only two classes that are used: ÀÌÙÔÐ for control parameters and ÀÓØ for iconic data. There is no need for other classes as long as the program has the same functionality as in HDevelop. When editing a generated program you are free to use any of the classes of HALCON/C++ to extend the functionality. 4.1.4 Limitations and Troubleshooting Besides the restrictions mentioned in this section and in section 4.4, please also check the description of the HDevelop operators on page 38. 4.1.4.1 Exception Handling In HDevelop, every exception normally causes the program to stop and report an error message in a dialog window. This might not be useful in C++. In addition, there are different default behaviors concerning the result state of operators. Messages In the case of C++ only severe errors cause an exception handling which terminates the program and prints an error message. This might cause problems with minor errors, so called messages in HALCON. These messages are handled as return values of the operators and can have the following values, which are also available in HDevelop as constants: ÀÅËÌÊÍ ÀÅËÄË ÀÅËÁÄ ÀÅËÎÇÁ HALCON 6.0
