Please help !!!
I’m trying to run an a c/c++ program using Pro*C/C++, I’m clicking the “rebuilt all” on the “build” menu and I get following error:
Deleting intermediate files and output files for project 'Cv_demo - Win32 Debug'.

I tried to recompile CV_DEMO.PC in Proc*C/C++ and it compiled ok, however when I try to do this in C/C++ I get this error.
I will greatly appreciate it if any one can help me with this problem (I started with Pro*C/C++ last week).
I’m using : Oracle 7.3 and 8, Pro*C/C++ 8.0.5.00, Visual C++ 6.0
The CV_DEMO.PC is as follow:
#include <STDIO.H>
#include <STDLIB.H>
#include <SQLCA.H>
/* Error handling function. */
void sql_error(void)
{
EXEC SQL WHENEVER SQLERROR continue;
printf("%.70s\n", sqlca.sqlerrm.sqlerrmc);
exit(1);
}
void main()
{
char temp32;
EXEC SQL BEGIN DECLARE SECTION;
char db_string20 = "PROD";
char password20 = "highlander";
char userid 10 = "lsagi";
char db_name10 = "PROD";
SQL_CURSOR emp_cursor;
int dept_num;
struct
{
int emp_num;
char emp_name11;
char job10;
int manager;
char hire_date10;
float salary;
float commission;
int dept_num;
} emp_info;
struct
{
short emp_num_ind;
short emp_name_ind;
short job_ind;
short manager_ind;
short hire_date_ind;
short salary_ind;
short commission_ind;
short dept_num_ind;
} emp_info_ind;
EXEC SQL END DECLARE SECTION;
EXEC SQL WHENEVER SQLERROR do sql_error();
EXEC SQL DECLARE prod DATABASE;
/* Connect to Oracle. */
EXEC SQL CONNECT :userid IDENTIFIED BY :password
at :db_name using :db_string;
/* Allocate the cursor variable. */
EXEC SQL ALLOCATE :emp_cursor;
/* Exit the inner for (;;) loop when NO DATA FOUND. */
EXEC SQL WHENEVER NOTFOUND DO break;
for (;;)
{
printf("\nEnter department number (0 to exit): ");
gets(temp);
dept_num = atoi(temp);
if (dept_num <= 0)
break;
EXEC SQL EXECUTE
begin
emp_demo_pkg.open_cur(:emp_cursor, :dept_num);
end;
END-EXEC;
printf("\nFor department %d--\n", dept_num);
printf("ENAME\t SAL\t COMM\n");
printf("-----\t ---\t ----\n");
/* Fetch each row in the EMP table into the data struct.
Note the use of a parallel indicator struct. */
for (;;)
{
EXEC SQL FETCH :emp_cursor
INTO :emp_info INDICATOR :emp_info_ind;
printf("%s\t", emp_info.emp_name);
printf("%8.2f\t\t", emp_info.salary);
if (emp_info_ind.commission_ind != 0)
printf(" NULL\n");
else
printf("%8.2f\n", emp_info.commission);
}
}
/* Close the cursor. */
EXEC SQL CLOSE :emp_cursor;
exit(0);
