winapi - Simple Hello World in x86 ASM - Windows console -

i'm trying run following hello word example in x86 assembly under windows:

global _main extern  _getstdhandle@4 extern  _writefile@20 extern  _exitprocess@4  section.text _main : ; dword  bytes; mov     ebp, esp sub     esp, 4  ; hstdout = getstdhandle(std_output_handle) push - 11 call    _getstdhandle@4 mov     ebx, eax  ; writefile(hstdout, message, length(message), &bytes, 0); push    0 lea     eax, [ebp - 4] push    eax push(message_end - message) push    message push    ebx call    _writefile@20  ; exitprocess(0) push    0 call    _exitprocess@4  ; never here hlt message : db      'hello, world', 10 message_end : 

following error when trying link assembled .obj file:

error lnk2001: unresolved external symbol _getstdhandle@4
error lnk2001: unresolved external symbol _writefile@20
error lnk2001: unresolved external symbol _exitprocess@4
fatal error lnk1120: 3 unresolved externals

source of example: how write hello world in assembler under windows?

how fix these? or also, why isn't example working me?

when using c compiler standard libraries typically linked code typically not done when calling linker separately.

the 3 functions located in "kernel32.dll" you'll have link against "kernel32.lib" (or "libkernel32.a" when using gnu tools).

your entry point "_main" assume want use startup object files, too.

however not neccessary in case may define "_main" linker entry point , not link against startup object files.
