I've made projects before where I've successfully compiled and linked
togeather multiple C++ files.  So I decided to try to do the same with
one C++ file and an ASM file.  I was searching for examples of ASM files
that used .intel_syntax and pretty much found only one.  So I used that
example for my ASM file (.s file) and then made a C++ file that called
the routine in the .s file.  The routine in the .s file doesn't work,
but that's not important.  All I want to know, is why I get the errors
I'm getting when Rhide goes to link the files togeather.  First I'll
show .s file, then the .cpp file, and then the error.  Thanks in advance
for your help.
global _start 
.intel_syntax noprefix 

.section .text 
_start: 

mov eax, 4 
mov ebx, 1 
mov ecx, offset msg 
mov edx, msg_len 
int 0x80; 

xor eax, eax 
inc eax 
int 0x80 

.section .data 
msg: .ascii "Hello, from gas " 
msg_len = .-msg 

Now, the C++ Part: 
extern void start(); 
main(void) 
{ 
start(); 
return 0; 
} 

Now the errors: 

-[_]--------------------------- Message Window
-------------------------4-[]-
Creating: asm.exe 
Error: casmtest.o: In function `main': 
casmtest.cpp(4) Error: undefined reference to `start()' 
Error: casmtest.o(.eh_frame+0x11):casmtest.cpp: undefined reference to

There were some errors
