## Ubuntu (Kylin) 14.04
### Build Dependencies
This installation document assumes Ubuntu 14.04 or later on x86-64 platform.
##### Install YASM
Erasure depends on Intel ISAL library, ISAL uses Intel AVX2 processor instructions, to compile these files one needs to install ``yasm`` which supports AVX2 instructions. AVX2 support only ended in ``yasm`` from version ``1.2.0``, any version below ``1.2.0`` will throw a build error.
```sh
$ sudo apt-get install yasm
```
##### Install Go 1.4+
Download Go 1.4+ from [https://golang.org/dl/](https://golang.org/dl/) and extract it into ``${HOME}/local`` and setup ``${HOME}/mygo`` as your project workspace folder.
For example:
```sh
.... Extract and install golang ....
$ wget https://storage.googleapis.com/golang/go1.4.linux-amd64.tar.gz
$ mkdir -p ${HOME}/local
$ mkdir -p $HOME/mygo
$ tar -C ${HOME}/local -xzf go1.4.linux-amd64.tar.gz
.... Export necessary environment variables ....
$ export PATH=$PATH:${HOME}/local/go/bin
$ export GOROOT=${HOME}/local/go
$ export GOPATH=$HOME/mygo
$ export PATH=$PATH:$GOPATH/bin
.... Add paths to your bashrc ....
$ echo "export PATH=$PATH:${HOME}/local/go/bin" >> ${HOME}/.bashrc
$ echo "export GOROOT=${HOME}/local/go" >> ${HOME}/.bashrc
$ echo "export GOPATH=$HOME/mygo" >> ${HOME}/.bashrc
$ echo "export PATH=$PATH:$GOPATH/bin" >> ${HOME}/.bashrc
```
