去年宏定义字符中间的空格，改成如下试试：
ifndef __ASM
define __ASM
......
endif
[md]谢谢 这样试了不行

宏定义命令与字符之间至少需要一个空格，字符内部不能有空格。
ifndef的判断字符要与后一句的字符相同，否则容易出现重定义的错误。
您的判断字符是"__ASM"，而之后定义的却是 "ASM asm"，这样前面的判断语句就失去了作用。
define ASM asm的意思是定义一个宏"ASM"，其值为"asm"。您确定是要这样做吗？
建议复制下列代码：
[md]你好 代码如下 还是一样报错 谢谢 #ifndef __ASM #define __ASM __asm #endif

这些报错与宏定义关系不大，需要针对相应出错的代码进行检查，尤其是需要在IDE平台检查相应的文件路径是否包含了。宏定义是没有再报错了。
[md]这么改不太对 换成iar没这个报错
