Instructions:

Dolphin has recently gained support for ARM in the master branch. Let's see how to make it.

Setting up to Build

First, make sure you have the correct dependencies installed. For example, if you are using Ubuntu, use apt-get as follows:

sudo apt-get install make cmake git g++ libsdl1.2-dev libxrandr-dev libxext-dev libao-dev libasound2-dev libpulse-dev libbluetooth-dev libreadline-gplv2-dev libavcodec-dev libavformat-dev libswscale-dev


If you want to have a GUI, then install run this:

sudo apt-get install make cmake git g++ libgtk2.0-dev libsdl1.2-dev libxrandr-dev libxext-dev libao-dev libasound2-dev libpulse-dev libbluetooth-dev libreadline-gplv2-dev libavcodec-dev libavformat-dev libswscale-dev

If you run a distribution without aptitude, see the build dependencies below for a list of packages you will need to install.

Get a local copy of the dolphin-emu repository:
git clone https://code.google.com/p/dolphin-emu/ dolphin-emu


Change to the directory created:
cd dolphin-emu

Later, if you wish to update your local copy:
git pull origin
Building

Create a build subdirectory, and change into it.
mkdir Build && cd Build

Configure the build:
cmake -DUSE_GLES=True -DDISABLE_WX=True ..

If you are building with the GUI, configure it this way:
cmake -DUSE_GLES=True ..

From here build and install in the standard make way:
make

I would personally recommend building multi-threaded:
make -j5

Be warned, if you're building with a GUI, it is going to take quite a bit of time to build.
