Hello everyone! I was playig with MS COFF file format, but I get problems after linking obj file Sad

I think I have problem in imports.. here's code and error.

Code:

format MS COFF
include 'win32ax.inc'
extrn printf
public _myproc1

section '.text' code readable executable
proc _myproc1
     push msg
     call dword[printf]
     add esp,4
     ret
endp
section '.data' data readable writeable
msg db "Hello, World!",0

Code:

ld testobj.obj
testobj.obj.text+0x7): undefined reference to `printf'

P.S I'm using GCC's ld.exe

How come you are always tired when you fail to do something?

Because I don't have time for such things, I'm working too hard and trying to learn such things when I'm tired. Happy now ?
