I remembered that I cannot compile it successfully before. But after I compiled the LibUV, and added the header file & libs, I can build libev successfully.

I wrote this guide because after getting my CubieBoard 1 I followed the Arch Linux ARM instructions and was suprised to be left with a system that albeit working, had missing RAM and no fbconsole at all.
This guide gets Arch Linux ARM into your 1GB Cubieboard 1 with the minimum functionality one would expect. It is not intended to be an all encompassing document, focusing instead on saving your time having to read through the forum to get functionality that otherwise every other Linux distribution brings out of box.
You will have to adjust these instructions if you have a 512M Cubieboard.
At a minimum, you need to create the first partition on an SD card to store the bootloader files and kernel uImage. For the root filesystem you can choose to use either a second partition on the SD card, USB or SATA. This guide however only covers SD. Replace instances of /dev/mmcblkX with the appropriate device name registered on your system.

This guide is to save other sorry plebs from needing to RTFM in figuring out how to use wget to scrape images from 4chan and other imageboards. There are lots of image downloaders in existence, but they are usually outdated and broken. You will save time following this guide to learn how to use a powerful and general purpose tool instead.
Wget is a command-line file downloader that can handle just about any file downloading task normal and power users will ever need to do. It has versions available for Windows, Mac, and Linux. If it is not already installed on your machine, install it now.
