openwrt on mini2440

在openwrt dream-box官网下载openwrt源码，其中支持mini2440 boards

https://dev.openwrt.org.cn/wiki/GetSource

下载好之后，进行编译，可以参照如下教程

https://dev.openwrt.org.cn/wiki/howto

编译过程出现问题和解决方法记录如下:

error1：

In file includedfrom clean-temp.h:22:0,

from clean-temp.c:23:

./stdio.h:456:1:error: 'gets' undeclared here (not in a function)

_GL_WARN_ON_USE(gets, "gets is a security hole - use fgets instead");

找到：host-m4-1.4.15/lib/stdio.h，然后对stdio.h文件做出如下改动，必要时连同stdio.in.h一起修改：

error 2:

参考trunk的源码和此问题"https://dev.openwrt.org.cn/ticket/45"
修改 ./build_dir/host/mklibs/src/mklibs-readelf/elf.cpp，添加如下语句

#include <unistd.h>
