推荐一个我认为不错的winavr下的makefile
用了很多年winavr，makefile就是用Mfile生成的那个，这个makefile有个不爽的地方就是生成的编译文件都在当前目录，源文件和编译文件在一起，搞的比较乱，不像iar或者keil，编译文件都在一个独立的目录里，比较清爽。最近看fatfs，发现里边的makefile写的很好，实现了obj文件在一个独立目录的功能，我将makefile稍加优化一下，特此推荐。献给喜欢用winavr的朋友。

上传了makefile文件，供下载。 能说明下好处在哪里就好了 yklstudent 发表于 2013-4-8 12:18 static/image/common/back.gif
能说明下好处在哪里就好了
已经说了啊：
实现了obj文件在一个独立目录的功能
请问一下我用你的makefile编译工程如下，是什么错误呢？
C:\Documents and Settings\Administrator\桌面 怎么方步了截图了，
