Rudys Delphi Corner Using C object files in Delphi. C is a very widely used language, and this has made the worldwide code library for C huge. The code library for Delphi is comparably small, so it would be nice if we could use parts of that huge library directly, without a translation of the entire code in Delphi. Fortunately, Delphi allows you to link compiled C object files.

Davids Audio Tools VectorScope check audio phasing or direction finding aid. But there is this problem with unsatisfied externals. Being a simple but powerful language, C gets most of its functionality from its runtime library. Almost all non trivial C code needs some of the functions in this library. But Delphis runtime doesnt contain these functions. So simply linking the C object file will make the linker complain about unsatisfied external declarations. Net Runtime Library for Delphi. The. Net Runtime Library for Delphi is the best library to work with. Net framework from Delphi. It is designed to provide a. Luckily, C accepts any implementation of such a function, no matter in which code module it is defined. If the linker can find a function with the desired name, it can be used. You can use this to provide missing parts of the runtime yourself, in your Delphi code. In this article I will demonstrate how to compile and link an object file into a Delphi unit, and provide the missing parts of the C runtime that it needs. For this, I will use the well known public domain regular expression search code that Henry Spencer of the University of Toronto wrote. I only slightly modified it to make it compile with CBuilder. Regular expressions are explained in short in the Delphi help files, and are a way of defining nifty search patterns. Object files. C normally generates object files, that are to be linked to an executable. On 3. 2 bit Windows, these usually have the file extension. But these come in different, incompatible formats. Microsofts C compiler, and some other compatible compilers, generate object files in a slightly modified COFF format. These cant be used in Delphi. Delphi requires OMF formatted object files. There is no practicable way of converting normal COFF object files to OMF, so you will need the source, and a compiler that generates OMF files. Note that the COFF2. OMF utility which comes with many versions of CBuilder is no help at all for this problem. It is only meant to convert import libraries from one format to the other. Import library files only contain information about the exported functions of a DLL, and can be generated from the DLL directly, using IMPLIB or a similar utility. They contain a very limited subset of what real C or C library files contain. COFF2. OMF will not convert C or C object or real library files see note below in the COFF format. You really need source code and a CBuilder compiler to produce OMF object files usable with Delphi. Update. Thaddy de Koning told me that the COFF2. OMF converter from Digital. Mars can do a complete conversion. I didnt try it, but he said it is worth its money. Update 2. Agner Fog, well known optimization guru, pointed me to his Obj. Conv tool, wich will convert several types of object files to several others. We are also working on making C generated OMF and non OMF generated object files usable in Delphi. Update 3. Delphi XE2 and following versions can also link COFF object files, so there is no need to use any of the converters described above. Also take a look at the new section about Win. BorlandCode. GearEmbarcaderos CBuilder does generate such OMF object files. But not each Delphi user has CBuilder as well. Luckily, Embarcadero still makes the command line compiler that came with Borland CBuilder 5 freely available. It can be downloaded from the last entry in the list on this page, if you provide some information. Test King Free Download here. If you dont have it yet, get it now. Since 1. 3 July 2. C command line compiler for 3. Windows from Embarcadero. It can be found on the Free C Compiler page. It is the Clang based C1. C compiler that comes with CBuilder 1. Berlin. It generates OMF object files. It comes with a number of Windows headers and command line tools. It is described in A new edition of our free C compiler by the new product manager, David Millington. There is another limitation to what kind of files you can use. You can only use object files that are compiled as C files, not C files. For some reason, the Delphi linker has problems with object files that contain C. This means that your source files must have the extension. But since you cant use C classes directly anyway, that is not a severe limitation. One note C often uses library. These simply contain multiple object files, and some C compilers come with a librarian program to extract, insert, replace or simply list object files in them. In Delphi, you cant link. But you can use the TDUMP utility that comes with Delphi and CBuilder to see what is stored in them. The free C compiler comes with the TLIB librarian to get at the single object files. The code. I will not discuss the mechanism or use of regular expressions here. There is enough material available in books and on the Internet. But to exploit them with this code, you first pass a regular expression pattern to a kind of very simple compiler, that turns the textual representation into a version that can easily be interpreted by the search code. The compilation is done by the function regcompile. To search a string for a regular expression pattern, you pass the compiled pattern and the string to the regexec function. It will return information about if, and where in the string, it found text matching the pattern. The complete implementation code for the regular expression search is rather complicated and long, so I will not show that. But the header file is of course important for the Delphi code using the object file. Here it is. 1. 7. Copyright c 1. 98.
