Coding Concurrent Programs in Pro*C

Question

If I have a pro*c program like this:
#include <stdio.h>
#include <string.h>
#include <stdlib.h>
#include "sqlca.h"
#include "sqlcpr.h"
EXEC SQL BEGIN DECLARE SECTION;
     VARCHAR username[20];
     VARCHAR password[20];
EXEC SQL END DECLARE SECTION;
void sqlerr();
int main()
     strcpy(username.arr,"SCOTT");
     username.len = strlen(username.arr);     
     strcpy(password.arr,"TIGER");
     password.len = strlen(password.arr);     
     EXEC SQL WHENEVER SQLERROR DO sqlerr();
     EXEC SQL CONNECT :username IDENTIFIED BY :password;
     EXEC SQL INSERT INTO EMP(EMPNO, ENAME, DEPTNO) VALUES(7777,'JACKIE',30);
     EXEC SQL commit;
     printf("Successful!");
     exit(0);
void sqlerr()
     printf("SQL Error!\n");
     exit(1);
I will give this file's extension name is:XXX.pc, and I transfer this pc file to $ORACLE_HOME/precomp/demo/proc and use this command "proc XXX.pc" to make this pc file to a C file. and use "make" command to generate XXX.o and XXX.e files.And the XXX.e is the executable file. And I can use this file to insert a record into emp table.
And now, I have a problem that I want to coding concurrent programs in Pro*C.There have a template of concurrent programs-----EXMAIN.c and EXPROG.c. And how shoule I modify and compile these two files? Should I modify the extension name to ".pc"? When I compile EXMAIN.c, use the command "make -f demo_proc.mk OBJS=EXMAIN.o EXE=EXMAIN.e build", there have problems of following:
cc -xO2 -Xa -xstrconst -xF -mr -xarch=v8 -xcache=16/32/1:1024/64/1 -xchip=ultra -D_REENTRANT -K PIC -DPRECOMP -I. -I/u01/COMV/applCOMV/COMVora/8.0.6/precomp/public -I/u01/COMV/applCOMV/COMVora/8.0.6/rdbms/public -I/u01/COMV/applCOMV/COMVora/8.0.6/rdbms/demo -I/u01/COMV/applCOMV/COMVora/8.0.6/plsql/public -I/u01/COMV/applCOMV/COMVora/8.0.6/network/public -DSLMXMX_ENABLE -DSLTS_ENABLE -c EXMAIN.c
"./afpub.h", line 46: cannot find include file: <afver.h>
"./afcp.h", line 36: cannot find include file: <fdpwrt.h>
cc: acomp failed for EXMAIN.c
*** Error code 2
make: Fatal error: Command failed for target `EXMAIN.o'
I don't know why.I hope somebody can help me!
Thanks !!

Hi !
Have you tried to replace the INCLUDE statements for SQLCA and SQLCPR
with the following:
EXEC SQL INCLUDE SQLCA;
EXEC SQL INCLUDE SQLCPR; ?
