用uClibc编译busybox的问题

xuxingpeng

为了时系统体积减小,使用了busybox.
打算在uClibc上编译busybox.
以下是我认为的大概的方式:
由于uClibc需要toolchain支持.于是下载了toolchain.
然后编译uClibc.安装uClibc
然后编译busybox-1.1.3

我的问题是
1.上面的方式我试过了,结果是busybox编译不同过,在LINK busybox_unstripped时出现错误

2.用不用把toolchain里的那些头文件之类的添加到原系统对应的地方.
3.怎么知道编译一个程序用的时uClibc还是glibc

谢谢!
