编译是可以编译了，但编译出来之后有些问题，不能够连接板子debug，似乎是工程配置还有问题。我以gpio例程为例试了一次。
build的时候/或者clean之后再build，提示没有<工程名>.elf文件，这个文件应该是自动编译生成的，为什么要我来提供？而且不知道为什么clean的时候会清除掉<工程名>.elf文件，我在官方例程中clean是不会清除的。
错误提示：

我自作聪明地把例程里面的elf文件拷贝到自建工程目录下，把文件名改为自建工程的文件名，结果能够顺利编译，但编译出来的大小是官方例程的4倍，源码都是一样的。而且debug出错，官方例程debug并不会出错。

对eclipes的操作还是很头大啊。
