embedded prolog in C

Arie #1 / 10	embedded prolog in C Hi guys, I am just getting started on this so I can't really go into too much detail, but I need to build an expert system in prolog, and do the user interface for it in C. Building the expert system is not that big of a deal and I am pretty sure on the prolog code, but I don't know much at all about embedding that to C. I AM a much much better in C than in prolog, but I can't seem to find much on the web about this. After doing some research, I found that I need the include file SWI-Prolog.h but SWI's sight only has the object oriented version, SWI-cpp.h Does anybody know a good source of info on this, or even better, give me an overview of how to go about embedding the prolog code into C? The biggest thing that's baffeling me is which program is responsible for the actual compiliation of code, my C compiler, or SWI? Any help about this is greatly appreciated. thank you. Arie

SWI-cpp.h is the C++ wrapper and used to be distributed as a seperate package (actually a real C++ programmer (Volker Wysk) is currently revising the C++ interface).

You can do everything yourself using your standard C tools or you can give part of the job to plld, a front-end that knows how to call the C-compiler and linker. The C-compiler is quite trivial (plld justs add a -I to the include directory, so the correct SWI-Prolog.h is found). The linker is a bit more hairy. The manual gives an overview. The twiki web reachable through the home-page adds details on a number of platforms. You can run plld -v ... to see what it is doing.

terje.. #3 / 10	embedded prolog in C You might look at http://www.trolltech.com They might (no guarantees though), have what you need.

Arie #4 / 10	embedded prolog in C plld seems to be what I'm looking for! I spent many hours last night trying to compile a sample program from my home computer, but ran into many problems with vc++'s enviromental variables setup, but it seems to be working now. now all I need is to learn how to do the actual coding =\ thank you for your response!

Mike #5 / 10	embedded prolog in C I have a similar problem (I think)... I'm using Visual C++ 6. In refman to SWI Prolog I've found that SWI-prolog.h must be included, and several functions can be used (PL_query_open, ...). The problem occures when I'm linking my project. There are no code for these functions. What should I do? Should Prolog be working while linking or running C application? Please help. Mike

You should link against libpl.dll, which can be found in the lib directory of the distribution. When running you should make sure the DLL's of the bin-directories can be found. Best add this directory to %PATH%, the include directory to %INCLUDE% and the lib directory to %LIB%. See also plld.exe and the SWI-Prolog twiki web. Cheers --- Jan
