怎么设置BC++5。0的环境/可以用Embedded SQL连上SYBASE进行数据操作

[BallyTan]

下面是我从 SQL ANYWHERE STUDIO 8。0的手册上抄来的
可惜我用BC++5。0编译不成功/

#include <stdio.h>
EXEC SQL INCLUDE SQLCA;
main()
{
db_init( &sqlca );
EXEC SQL WHENEVER SQLERROR GOTO error;
EXEC SQL CONNECT "DBA" IDENTIFIED BY "password";
EXEC SQL UPDATE employee
SET emp_lname = 'Plankton'
WHERE emp_id = 195;
EXEC SQL COMMIT WORK;
EXEC SQL DISCONNECT;
db_fini( &sqlca );
return( 0 );

error:
printf( "update unsuccessful -- sqlcode = %ld.n",
sqlca.sqlcode );
db_fini( &sqlca );
return( -1 );
}

我不会设置环境，那位教我一下/谢谢
