I've some problems to compile a very simple hello_world apps
(not with RTEMS matter yet). This is the steps that I've followed:

- download of complete Cygwin tool-chain on PC directory

- installation of Cygwin from directory onto c:\bin\cygwin

- download of following files from FTP OARCORP (working cd directory):


- start of cygwin environment

- copy of all rtems files onto root directory

- unpack of rtems files between followin command:

   tar -xjf <rtems_file>

   in following order:
   1°)   rtems-base-binutils-
   2°) rtems-base-gcc-gcc3.2.1newlib1.11.0-2.tar.bz2
   3°)  m68k-rtems-binutils-
   4°)  m68k-rtems-c++-gcc3.2.1newlib1.11.0-2.tar.bz2
   5°)  m68k-rtems-gcc-gcc3.2.1newlib1.11.0-2.tar.bz2

   THANK YOU to:
    gregory menke
    Joel Sherrill
    for this tips

- wrote this in bash session:

   export  PATH=/opt/rtems/bin:$PATH

- wrote this in my home, hello_word.c file

  int main(void)
      return 0;

- launched compilator with:
  $ m68k-rtems-gcc.exe hello_word.c
warning:cannot find entry symbol _start; defaulting to 80000074

What I mistake ? Because I can't compile a so simple program ?

Thank you very much
