nasm/ld未能做到％include在cygwin上

我想在Cygwin 32位上使用nasm進行彙編（第四部分Dandamudi，Sivarama P. Linux中彙編語言編程指南 New York：Springer， 2005）。nasm/ld未能做到％include在cygwin上

不過，我得到以下錯誤：

$ nasm -f win32 sample.asm 
$ nasm -f win32 io.mac 
$ ld -m i386pe io.obj -lc sample.obj -o sample.exe 
sample.obj:sample.asm:(.text+0x7): undefined reference to `proc_PutStr' 
sample.obj:sample.asm:(.text+0x19): undefined reference to `proc_GetStr' 
sample.obj:sample.asm:(.text+0x26): undefined reference to `proc_PutStr' 
sample.obj:sample.asm:(.text+0x2e): undefined reference to `proc_GetInt' 
sample.obj:sample.asm:(.text+0x3e): undefined reference to `proc_PutStr' 
sample.obj:sample.asm:(.text+0x49): undefined reference to `proc_PutInt' 
sample.obj:sample.asm:(.text+0x56): undefined reference to `proc_PutStr' 
sample.obj:sample.asm:(.text+0x63): undefined reference to `proc_GetCh' 
sample.obj:sample.asm:(.text+0x80): undefined reference to `proc_PutStr' 
sample.obj:sample.asm:(.text+0x8c): undefined reference to `proc_PutStr' 
sample.obj:sample.asm:(.text+0x92): undefined reference to `proc_nwln' 
$

現在，io.mac有參考外部程序（如proc_GetStr和proc_GetCh，我以爲來自外部庫），但我做不到找到如何引用這些外部信息。

任何人都可以建議我該怎麼辦？

下面是各種代碼/闡述：

你的錯誤是組裝io.mac。它是「原樣」包含在sample.asm中的文本文件。 io.obj是不是組裝io.mac。隨着組裝io.mac你破壞了原來的io.obj。但即使您從win_nasm_progs.zip中提取原始io.obj，也會失敗。它是而不是一個Windows文件，但一個MS-DOS文件（是的，這是非常討厭）。你不能使用Linux文件（io.o），因爲Cygwin需要Windows系統調用。所以你不能在Linux之外使用Dandamudi的書。我唯一想到的是將io.mac中的調用更改爲調用C函數（以及其他調整），並將對象文件與GCC鏈接起來。

我（這在Cygwin/NASM作品）決定放棄從_Guide的I/O方案到Linux_中的彙編語言編程，並使用Paul Carter的PC彙編語言（適用於Cygwin/nasm）。北卡羅來納州羅利：露露出版社，2007年 – boardrider 2014-12-07 15:17:21

我決定放棄從指南匯編語言程序設計的I/O方案的Linux並與走Carter, Paul A. PC assembly language. Raleigh, NC: Lulu Press, 2007（即其driver.c cdecl.h asm_io.inc asm_io.asm文件）
