asm是不可移植的。肯定要用专门的汇编器。如果确实是gnu arm asm的话，那就要gnu的arm汇编器了。

就说，我必须用gnu的arm asm 编译？

看起来是gnu arm asm？

谢谢你的建议，我比较了一下，也把文件用armasm变发现很多错误，用masm也一样。因为生成的文件头不对。我用过 perl aes-armv4.pl > aes-armv4.asm 生成的文件和直接执行perl aes-armv4.pl显示的是一样的。
文件头却是
.text
.code 32

.type AES_Te,%object

正常的写法

AREA |.text|, CODE

也不应该正常的后面应该跟函数声明，这个生成的文件也没有函数声明。
还有很多别的编译错误

我前面说了，你哪两句话是不正确的。

>perl aes-armv4.pl 只能是显示这个脚本的内容
这句话是不正确的。也就是说，这条命令的输出并不是“脚本的内容”。你要做的就是自己再仔细检查下，输出和内容的区别。

>它本身不是可执行的perl，没有函数入口。
Perl脚本并不需要什么“函数入口”。脚本里有什么执行什么。

简单的来说，执行这个脚本，得到的输出是一个asm源代码。你可能要找个汇编器编译下。
