====== Installing EDE on an MK802 device ======

===== Introduction =====

The [[https://www.miniand.com/products/MK802%20Android%20Mini%20PC|MK802]] is a small and cheap ''ARM'' powered mini PC with ''HDMI'' output, designed for
playing media, browsing the internet or to be put to general use.

By default ''MK802'' comes with the Android OS, but this tutorial will show you how to run ''EDE'' on ''Linux'' (to be precise, ''(L)Ubuntu'') compiled and prepared for MK802. This tutorial is written using an ''MK802+'' model (Allwinner A10 CPU, DDR3 1GB RAM and 4GB ROM), but is applicable for all newer ''MK802''
versions.

Here is an image of one of the available models:

===== Preparations =====

Assuming you already have an ''MK802'' as well as a ''%%MicroSD%%'' card (this is where ''Ubuntu'' will be installed as we are not going to
overwrite the default Android installation on device ROM), first go to [[https://www.miniand.com/forums/forums/2/topics/1|this]] page and
download the ''Lubuntu'' version which matches your device memory size, then follow the instructions (written on the same page) on how to install it on
the ''%%MicroSD%%'' card.

:!: **Note:** You can also use an external USB drive instead of a ''%%MicroSD%%'' card; this will make things work considerably faster.

It is advised you use a 720p version as graphics will be faster.

By default, the image is intended for plugging the ''MK802'' device in a TV. In case you are going to plug the device in a computer, make sure to
download the zipped //evh.bin// files from [[http://www.rikomagic.co.uk/forum/viewtopic.php?f=2&t=13&start=20#p382|here]]
and replace the version on your ''%%MicroSD%%'' card with the appropriate one from there.

Now plug in the card and you should have a running ''Ubuntu'' system with the ''LXDE'' environment (password for logging in is **miniand**).

===== Installing required packages =====

After you have ''Ubuntu'' running, installing the required packages is simple;
just run these commands:

<code>
$ sudo apt-get update
$ sudo apt-get install g++ jam libfltk1.3-dev libdbus-1-dev
</code>

===== Installing EDE =====

From here on installing ''EDE'' from source code should not be a problem; please read InstallingFromSource for further instructions. However, if
you get an error like:

<code>
C++ applets/clock/Clock.o 
Link applets/clock/clock.so 
/usr/bin/ld: /opt/ede/lib/libedelib.a(Debug.o): relocation R_ARM_THM_MOVW_ABS_NC against `a local symbol' can not be used when making a shared object; recompile with -fPIC
/opt/ede/lib/libedelib.a: could not read symbols: Bad value
collect2: ld returned 1 exit status
</code>

this is a [[https://bugs.launchpad.net/ubuntu/+source/gcc-4.4/+bug/503448|known]] Ubuntu bug. In this case make sure to recompile ''edelib'' as a shared library (running //./configure --enable-shared// in the ''edelib'' folder will do it).
