root@bob-VirtualBox:~/lepd-src# make ARCH=arm

编译的过程中你可能会遇到如下问题：

lepd uses VFP register arguments, lepd/libs/arm-libev/libev.a(ev.o) does not

这可能是因为你的工具链加了 -mfloat-abi=hard

如果基线不允许修改这个参数，那么你可以自行编译libev（我是这么做的）

libev可以通过如下方式下载：

git clone https://github.com/enki/libev.git

关于编译libev我这里手顺是：

./configure --prefix=/home/xxx/elp/ --host=arm （这之前我source了yocto的sdk脚本environment-setup-cortexa9hf-neon-poky-linux-gnueabi）

make

然后cp libev.a 到 lepd/libs/arm-libev/libev.a

继续完成lepd编译


## 如何运行

运行lepd需要root权限，因为系统有些proc文件无root权限无法读取。
