openwrt安装依赖库

在openwrt-cgminer\allcode\openwrt\feeds\packages\utils路径下增加eudev文件夹

 

 

 

 eudev目录下有一些patches、配置文件以及makefile文件

 

 

 Makefile文件中会说明安装包的一些信息：

具体makefile文件编写的格式可参考：

https://www.freesion.com/article/3323420807/

这个eudev文件是我从其他源码中拷贝的。

然后执行下面两条命令：

?

1 2	./script/feeds update packages ./script/feeds install -a -p packages

在执行第二条命令时就可以看到打印信息显示eudev安装成功。

这个时候make menuconfig进去libraries项可以看到libudev的配置。

在.packageinfo文件中也可以看到这个库的具体信息：

 

 从上述信息可以看出安装包名字为eudev-3.2.tar.gz。此时我会拷贝一个eudev包到dl文件夹中去，在编译时就会直接使用，不用编译时才下，缩短编译时间。
