Re: Linking prolog code

[Daniel Diaz]

Hello Jose Maria,

You can compile your own C code (not interfacing Prolog) using gcc as well as 
gplc (you can pass C compiler options using the -C gplc option), so the 
following command lines work:

   gcc FLAGS -c -o my_own_c_doe.o my_own_c_code.c
   gplc -C "FLAGS" -c my_own_c_code.c

Your C code interfacing Prolog is compiled using gplc (as shown above)

   gplc -C "FLAGS" -c prolog_control_interface.c

Your Prolog code is compiled using gplc:

  gplc -c controler.pl

To link:

   gplc -o EXECNAME controler.o prolog_control_interface.o asmstuff.o 

You can obviously do the same in one command-line (even if not realistic 
using a Makefile):

   gplc -o EXECNAME controler.pl prolog_control_interface.c my_own_c_code.c 
asmstuff.o


To see the command-lines invoked by gplc use the -v option
