assembly - 不能在 NASM 中包含文件

Question

我尝试使用以下命令将文件包含到我的 boot.asm 文件中

%include "input.asm"

但是每次我尝试编译它时，我都会收到一条错误消息，说 nasm 无法打开包含文件。 input.inc与 boot.asm 位于同一目录中
我在这里和谷歌上寻找答案，但没有一个对我有帮助。

在包含之前是否有一种特殊的方式应该编译/格式化包含文件？还是只是我的 nasm 对我吠叫？

编辑:这是包含的代码:

mov ax, 0x07C0  ; set up segments
mov ds, ax    mov es, ax
mov si, welcome
call print_string
mov si, welcome2    
call print_string    
mov si, welcome4    
call print_string  
jmp .mainloop

%include 'input.asm'
mainloop:    ;loop here

输入.asm:

 ; ================
 ; calls start here
 ; ================

 print_string:
   lodsb        ; grab a byte from SI

   or al, al  ; logical or AL by itself
   jz .done   ; if the result is zero, get out

   mov ah, 0x0E
   int 0x10      ; otherwise, print out the character!

   jmp print_string

 .done:
   ret

 get_string:
   xor cl, cl

 .loop:
   mov ah, 0
   int 0x16   ; wait for keypress

   cmp al, 0x08    ; backspace pressed?
   je .backspace   ; yes, handle it

   cmp al, 0x0D  ; enter pressed?
   je .done      ; yes, we're done

   cmp cl, 0x3F  ; 63 chars inputted?
   je .loop      ; yes, only let in backspace and enter

   mov ah, 0x0E
   int 0x10      ; print out character

   stosb  ; put character in buffer
   inc cl
   jmp .loop

 .backspace:
   cmp cl, 0    ; beginning of string?
   je .loop ; yes, ignore the key

   dec di
   mov byte [di], 0 ; delete character
   dec cl       ; decrement counter as well

   mov ah, 0x0E
   mov al, 0x08
   int 10h      ; backspace on the screen

   mov al, ' '
   int 10h      ; blank character out

   mov al, 0x08
   int 10h      ; backspace again

   jmp .loop    ; go to the main loop

 .done:
   mov al, 0    ; null terminator
   stosb

   mov ah, 0x0E
   mov al, 0x0D
   int 0x10
   mov al, 0x0A
   int 0x10     ; newline

   ret

 strcmp:
 .loop:
   mov al, [si]   ; grab a byte from SI
   mov bl, [di]   ; grab a byte from DI
   cmp al, bl     ; are they equal?
   jne .notequal  ; nope, we're done.



   cmp al, 0  ; are both bytes (they were equal before) null?
   je .done   ; yes, we're done.

   inc di     ; increment DI
   inc si     ; increment SI
   jmp .loop  ; loop!

 .notequal:
   clc  ; not equal, clear the carry flag
   ret

 .done:     
   stc  ; equal, set the carry flag
   call print_string
   ret

错误消息:

D:\ASMT\boot.asm:14: fatal: unable to open include file `input.asm'

看来NASM包括当前目录中的文件:

Include files are searched for in the current directory (the directory you're in when you run NASM, as opposed to the location of the NASM executable or the location of the source file), plus any directories specified on the NASM command line using the -i option.

如果您正在执行 NASM从另一个目录 D:\ASMT在你的情况下，它不起作用是正常的。
