HOW TO: Install Mono 3.4.x on Ubuntu

Some weeks ago I had to install Mono 3.4 on Ubuntu. Sadly in Ubuntu repositories the Mono package is not up to date. In this HOW TO: Install Mono 3.4 on Ubuntu I will show you step by step how I did installed the latest version of Mono.

What is Mono?

As the official site of describes: “An open source, cross-platform, implementation of C# and the CLR that is binary compatible with Microsoft.NET”

Basically it make possible that C# and .NET programs can be run in any platform for example Ubuntu.

HOW TO Install Mono 3.4 on Ubuntu

I used some forums and sites as references:


First make sure you have NO mono in your machine:

apt-get purge mono-*

Install some dependencies

apt-get install libpng3 libpng3-dev libtool libtiff4 libtiff4-dev libexif12 libexif-dev libgif4 libgif-dev libpango1.0-dev libatk1.0-dev libgtk-3-0 libgtk-3-dev bison automake autoconf make gcc gtk-sharp2 build-essential xorg-dev libfreetype6 libfontconfig libfontconfig-dev gettext libglib2.0-dev git libjpeg-dev libjpeg8-dev libjpeg-turbo8-dev

Create a temp directory for downloading mono files

cd /root

mkdir -p install/mono

Get and install latest libgdiplus:

git clone

cd libgdiplus

./ --prefix=/usr


make install

Get and install lates Mono:

cd /root/install/mono

apt-get install mono-gmcs

git clone git://

cd mono

./ --prefix=/usr


make install

Get and install latest XSP 3.x

cd /root/install/mono

git clone <a href="git://" rel="nofollow">git://</a>

cd xsp

./ --prefix=/usr


make install

Test the installation

You should test if the installation was a success:

Check if mono was installed:

which mono

Check the version of mono

mono --version

Check the version of fastcgi

fastcgi-server-mono4 /version

Hope you have successfully installed mono on your Ubuntu machine!

    after commands
    >git clone git://
    >cd mono
    must be executed
    >git checkout 954ed3c91edeb8e22e336d7e7c9ad1a83a779f61
