[ECOS] Get problem on "Hello eCos world!"

[Frank Wu]

Hi,

I want generate a bin file which can boot up AT91SAM7256 and send
"Hello eCos world!" back to hyper terminal. I am new to eCos. Please
tell me if I did it right.
1) I use AT91SAM7SEK template default package to generate libtarget.a
ROM is selected to Startup type in Atmel AT91SAM7 HAL. Take out some
packages I do not need.
2) I changed hello.c (code see bellow) in c:\ecos\examples\ and use
the make file over there
3) using objcopy convert .elf file to .bin file
4) using SAM-BA load .bin file to board

I got compile problem at step 2). Please see code and error message bellow.
I am using gcc version 4.1.0

Thanks in advance,

-frank

hello.c
=====
/* this is a simple hello world program */
#include <stdio.h>
#include <cyg/kernel/kapi.h>      // Kernel API.
#include <cyg/infra/diag.h>      // For diagnostic printing.
int main(void)
{
while(1)
  {
  diag_printf( "Hello, eCos world!\n");
// Delay for 1 second.
  cyg_thread_delay( 100 );
  }
}

You are most likely using a more recent version of gcc, try compiling 
without the -finit-priority.
