编译是提示警告：Warning[w6]

如题，在编译的时候提示警告：Warning[w6]: Type conflict for external/entry "dis_bp", in module main against external/entry in module LCD; prototyped function vs K&R function 这是什么意思，怎么解决？

Ken Wang：

dirtwillfly，

  这个问题是在编译什么样的工程，基于什么样的芯片出现的？光看这个比较难定位问题。

谢谢

协议栈编译时候出现的，cc2541芯片

回复 li chang:

旁友,请问这个问题解决了吗,我现在也碰到这个问题了,有点莫名其妙,吃个饭回来就变这样了

Susan Yang：

回复 wei shi5:

Warnin[w6]的问题可能是由于头文件错误产生，根据您的错误提示，应该是重复定义了

wei shi5：

回复 Susan Yang:

不是的,之前编译都没有错误,吃个饭回来就这样了,而且都是协议栈的东西,我根本都没动过,

回复 wei shi5:

别忘了#include 相应的头文件

如果头文件是自己写的库，注意函数类型等是否有错误
