FASM 将 Hello World 写入控制台，完全没有包含或依赖项 [英] FASM write Hello World to console with NO includes or dependencies at all
问题描述
我见过
如何在Windows下用汇编程序编写hello world?
和
使用 DOS 在 Fasm 中编写 hello,world 到控制台
我已经尝试/看到过这样的代码，例如来自 这个答案
I've tried / seen code like this MASM example from this answer
;---ASM Hello World Win64 MessageBox
extrn MessageBoxA: PROC
extrn ExitProcess: PROC
.data
title db 'Win64', 0
msg db 'Hello World!', 0
.code
main proc
sub rsp, 28h
mov rcx, 0 ; hWnd = HWND_DESKTOP
lea rdx, msg ; LPCSTR lpText
lea r8, title ; LPCSTR lpCaption
mov r9d, 0 ; uType = MB_OK
call MessageBoxA
add rsp, 28h
mov ecx, eax ; uExitCode = MessageBox(...)
call ExitProcess
main endp
End
(我在 Windows 64 位 extrn MessageBoxA:PROC 上收到错误非法指令"，因为 FASM 不理解该 MASM 指令.)
(to which I get an error "Illegal instruction" on windows 64 bit extrn MessageBoxA:PROC because FASM doesn't understand that MASM directive.)
还有这个 FASM 示例 来自这个问题
also this FASM example from this question
; Example of 64-bit PE program
format PE64 GUI
entry start
section '.text' code readable executable
start:
sub rsp,8*5 ; reserve stack for API use and make stack dqword aligned
mov r9d,0
lea r8,[_caption]
lea rdx,[_message]
mov rcx,0
call [MessageBoxA]
mov ecx,eax
call [ExitProcess]
section '.data' data readable writeable
_caption db 'Win64 assembly program',0
_message db 'Hello World!',0
section '.idata' import data readable writeable
dd 0,0,0,RVA kernel_name,RVA kernel_table
dd 0,0,0,RVA user_name,RVA user_table
dd 0,0,0,0,0
kernel_table:
ExitProcess dq RVA _ExitProcess
dq 0
user_table:
MessageBoxA dq RVA _MessageBoxA
dq 0
kernel_name db 'KERNEL32.DLL',0
user_name db 'USER32.DLL',0
_ExitProcess dw 0
db 'ExitProcess',0
_MessageBoxA dw 0
db 'MessageBoxA',0
但它显示一个消息框并且还具有外部依赖项kernel32.dll"和user32.dll"
but it displays a message box and also has external dependencies "kernel32.dll" and "user32.dll"
还尝试了这个例子 来自 FASM 论坛
format pe console
include 'win32ax.inc'
entry main
section '.data!!!' data readable writeable
strHello db 'Hello World !',13,10,0
strPause db 'pause',0
section '.txt' code executable readable
main:
; you can use crt functions or windows API.
cinvoke printf,strHello
cinvoke system,strPause; or import getc()
; or
; invoke printf,srtHello
; add esp, 4
; or use WriteFile and GetStdHandle APIs
push 0
call [ExitProcess]
section '.blah' import data readable
library kernel32,'kernel32.dll',\
msvcrt,'msvcrt.dll' ;; C-Run time from MS. This is always on every windows machine
import kernel32,\
ExitProcess,'ExitProcess'
import msvcrt,\
printf,'printf',\
system,'system'
但它依赖于 win32ax.inc 和其他导入
but it depends on win32ax.inc and other imports
还有
format PE console
include 'win32ax.inc'
.code
start:
invoke WriteConsole,<invoke GetStdHandle,STD_OUTPUT_HANDLE>,"Hello World !",13,0
invoke Sleep,-1
.end start
但需要win32ax.inc"；导入
but requires "win32ax.inc" import
在没有 win32ax 的情况下我能找到的最接近的来自 FASM 论坛:
closest I could find without the win32ax from the FASM forum:
format pe64 console
entry start
STD_OUTPUT_HANDLE = -11
section '.text' code readable executable
start:
sub rsp,8*7 ; reserve stack for API use and make stack dqword aligned
mov rcx,STD_OUTPUT_HANDLE
call [GetStdHandle]
mov rcx,rax
lea rdx,[message]
mov r8d,message_length
lea r9,[rsp+4*8]
mov qword[rsp+4*8],0
call [WriteFile]
mov ecx,eax
call [ExitProcess]
section '.data' data readable writeable
message db 'Hello World!',0
message_length = $ - message
section '.idata' import data readable writeable
dd 0,0,0,RVA kernel_name,RVA kernel_table
dd 0,0,0,0,0
kernel_table:
ExitProcess dq RVA _ExitProcess
GetStdHandle dq RVA _GetStdHandle
WriteFile dq RVA _WriteFile
dq 0
kernel_name db 'KERNEL32.DLL',0
user_name db 'USER32.DLL',0
_ExitProcess db 0,0,'ExitProcess',0
_GetStdHandle db 0,0,'GetStdHandle',0
_WriteFile db 0,0,'WriteFile',0
但仍需要 kernel32.dll 和 user32.dll
but still requires the kernel32.dll and user32.dll
有什么方法可以在没有任何外部 DLL 的情况下做到这一点?我知道只有程序 fasm 自己做，然后打印到控制台，不是吗?
Any way to do this without any external DLLs at all? I know just the program fasm itself does it, and prints to the console, doesn't it?
推荐答案
没有任何外部 DLL 的任何方法可以做到这一点?
Any way to do this without any external DLLs at all?
在 Windows 下:绝对没有！
Under Windows: Definitely no!
Windows 使用一些方法(可能是 syscall)进入操作系统，但是没有官方入口点.
Windows uses some methods (probably syscall) to enter the operating system, however, there are no official entry points.
这意味着在当前 Windows 版本中显示 Hello world" 消息框的完全相同的程序有可能(不太可能但是)在下一次 Windows 更新后执行完全不同的操作！
This means that it is (unlikely but) possible that exactly the same program that shows the "Hello world" message box in the current Windows version will do something completely different after the next Windows update!
因为微软假设每个 Windows 程序只使用与内核版本匹配的 .dll 文件调用操作系统，所以他们可以做到这一点.
Because Microsoft is assuming that every Windows program is only calling the OS by using the .dll files that match the kernel version, they can do this.
我不了解 Windows 10，但较旧的 Windows 版本(我不记得是 XP、Vista 还是 7)甚至只是假设 .exe 文件会立即返回如果它不使用任何 .dll 文件:在这种情况下程序甚至没有启动！
I don't know about Windows 10, but an older Windows version (I don't remember if it was XP, Vista or 7) even simply assumed that an .exe file returns at once if it does not use any .dll file: The program was not even started in this case!
