我尝试使用将文件包含到我的 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。
在包含之前是否应该编译/格式化包含文件的特殊方式?或者它只是我的 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

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

or al, al ; logical or AL by itself

jmp print_string
.done:
