Install dependencies

Code:

sudo apt-get install build-essential 
sudo apt-get install cmake
sudo apt-get install gcc-arm-linux-gnueabi
sudo apt-get install g++-arm-linux-gnueabi

Enter directory that will hold opencv
Code:
```
cd ~/Documents
```

Clone OpenCV from git

Code:

git clone https://github.com/Itseez/opencv.git

Checkout to a recent OpenCV release (change 2.4.10.1 to a recent release)
Code:
```
cd opencv
git checkout tags/2.4.10.1
```

Set toolchain to correct version of g++ (change line in file or run this complicated one-liner

Code:

cd platforms/linux

x=$(dpkg -s g++-arm-linux-gnueabi | grep "Version" | grep -o ".\.."); sed -i 's/set(GCC_COMPILER_VERSION "*.*"/set(GCC_COMPILER_VERSION \"'$x'\" CACHE STRING "GCC Compiler version"/g' arm-gnueabi.toolchain.cmake

Prepare file for build

Code:

mkdir build_roborio
cd build_roborio
cmake -DSOFTFP=ON -DCMAKE_TOOLCHAIN_FILE=../arm-gnueabi.toolchain.cmake ../../..

Build project (this will take a while)
Code:
```
make
```
