How to provide main task?

[Leon Pollak]

Hello.
	This must be primitive, but I do not succeed to follow the structure of 
includes...
	I created C++ application with the following main.cpp content:
------------------------------------------
#define CONFIGURE_INIT
#include "system.h"
#include <stdio.h>
#include <confdefs.h>
#undef CONFIGURE_INIT

#include <rtems.h>

extern "C" {
rtems_task Init(rtems_task_argument);
}

rtems_task Init( rtems_task_argument ){
    printf( "\n*** My Main Init Task Entry. ***\n" );
while(1);
}
------------------------------------------
The system.h file contains:
extern "C" {
rtems_task Init(rtems_task_argument);
}

#include <bsp.h> /* for device driver prototypes */

/* #define CONFIGURE_APPLICATION_NEEDS_CONSOLE_DRIVER */
#define CONFIGURE_APPLICATION_NEEDS_CLOCK_DRIVER
#define CONFIGURE_MAXIMUM_TASKS           1
#define CONFIGURE_MAXIMUM_SEMAPHORES      1
#define CONFIGURE_RTEMS_INIT_TASKS_TABLE
#define CONFIGURE_INIT_TASK_ENTRY_POINT   Init
#define CONFIGURE_INIT_TASK_NAME rtems_build_name( 'C', 'T', 'O', 'R')
#define CONFIGURE_USE_MINIIMFS_AS_BASE_FILESYSTEM
#define CONFIGURE_TICKS_PER_TIMESLICE        1

#include <confdefs.h>
------------------------------------------------

The problem is that linker says:

powerpc-rtems-g++ -B/opt/rtems/powerpc-rtems/mybsp/ -specs bsp_specs \
  -qrtems  -mcpu=860 -Dmpc860 -qrtems_debug -Wno-unused -ggdb  -g \
  -Wall -ansi -fasm -qnolinkcmds -o op /opt/FDR/OP/Build/main.o \
  -T linkcmds -Xlinker -Map -Xlinker map.map

/opt/rtems/rtems-bin/powerpc-rtems/FDR_GEN/lib/librtemscpu_g.a(dummy.o)(.data+0x20): 
undefined reference to `main'

Any help will be highly appreciated.
