font color=red Create/Modify forms and triggers through C++ using OPEN API

Question

<font color=red>
Dear brothers/sisters<font color=darkblue>
<br><br>
Please help us to find the linking problem.
<br>
We have to add PRE-FORM trigger to many FMBies. We have thousants of FMBies. So opening one by one is difficult. For this we are using OPEN API and BORLAND C++. We have coppied all header files from D:\orant\FORMS60\API.
But there is a link error. Here is the snippet.
<br>
<font color=red>
<br>#include <stdio.h>
<br>#include <stdlib.h>
<br>#include <malloc.h>
<br>#include <d2fctx.h> /* Forms API context */
<br>#include <d2ffmd.h> /* Form module header file */
<br>int main (int argc, char *argv[])
<br>{
<br>d2fctxa ctx_attr;
<br>d2fctx *ctx;
<br>d2ffmd *form;
<br>text *form_name;
<br>/* Check arguments */
<br>if ( argc != 2 )
<br>{
<br>fprintf(stderr, "USAGE: %s <filename>\n", argv[0]);
<br>exit(1);
<br>}
<br>/* Create Forms API context */
<br>ctx_attr.mask_d2fctxa = (ub4)0;
<br>if ( d2fctxcr_Create(&ctx, &ctx_attr) != D2FS_SUCCESS )
<br>{
<br>fprintf(stderr, "Error creating Forms API context\n");
<br>exit(1);
<br>}
<br>/* Load the form module into memory */
<br>if ( d2ffmdld_Load(ctx, &form, argv[1], FALSE) != D2FS_SUCCESS )
<br>{
<br>fprintf(stderr, "Failed to load form module: %s\n", argv[1]);
<br>exit(1);
<br>}
<br>/* Get the name of the form module */
<br>if ( d2ffmdg_name(ctx, form, &form_name) != D2FS_SUCCESS )
<br>{
<br>fprintf(stderr, "Error getting the name of the form module\n");
<br>}
<br>else
<br>{
<br>/* Print the name of the form, then free it */
<br>printf ("The name of the form is %s\n", form_name);
<br>free(form_name);
<br>}
<br>/* Destroy the in-memory form */
<br>if ( d2ffmdde_Destroy(ctx, form) != D2FS_SUCCESS )
<br>{
<br>fprintf(stderr, "Error destroying form module\n");
<br>}
<br>/* Close the API and destroy context */
<br>d2fctxde_Destroy(ctx);
<br>return 0;
<br>}

The compilation is success. But there is a link error. Please help us to find the problem.
