[Dev-C++] Linking Prolog Libraries

[Narayan A. <nan...@ly...>]

Hi all,

    I am trying to execute a c++ code that sends queries to a prolog engine back and forth. I got the following linker error when i tried to compile the code:

 C:\DOCUME~1\NARAYA~1.CAM\LOCALS~1\Temp\ccqubaaa.o: In function `_7PlTermvG6PlTermT1':
//C/PROGRA~1/pl/include/SWI-cpp.h(.text$__as__6PlTermPCc+0x16): undefined reference to `PL_unify_atom_chars'
//C/PROGRA~1/pl/include/SWI-cpp.h(.text$__7PlTermvi+0x13): undefined reference to `PL_new_term_refs'
//C/PROGRA~1/pl/include/SWI-cpp.h(.text$__7PlFrame+0xb): undefined reference to `PL_open_foreign_frame'
//C/PROGRA~1/pl/include/SWI-cpp.h(.text$_$_7PlFrame+0x15): undefined reference to `PL_close_foreign_frame'
//C/PROGRA~1/pl/include/SWI-cpp.h(.text$__7PlQueryPCcRC7PlTermv+0x20): undefined reference to `PL_predicate'
 ...
 ...
 ... 

My code is as follows:
#include <SWI-Prolog.h>
#include <SWI-cpp.h>
#include <string>

#include <iostream.h>


void loadit(){
   PlFrame fr;
   PlTermv av(1);
   av[0] = "test.pl";
   PlQuery q("consult", av);
   q.next_solution();
}
void start(){
     PlFrame fr;
     PlTermv av(1);
     av[0] = "Narayan";
     PlQuery q("receive", av);
     q.next_solution();
}

int main( int argc, char *argv[] )
{
   PlEngine e(argv[0]);
   loadit();
   start();
   cerr << "Prolog initialized" << endl;

   return 0;
}

It throws unreferenced errors to all the prolog terms that I have used in the program.

I have set the compiler options in the following way:

C++ incluce directories: <default>, include directory containing prolog header files

Library files: <default>, library containg prolog dll files.

Could anybody advice me on what I am missing here:

Thanks,
Narayan.
