Installing Mono 2.0 on Ubuntu 7.10

Currently the Mono project does not release Ubuntu binary packages so if you want the latest version of Mono you need to compile and install yourself. I use the Xubuntu, Here are the steps I took to install Mono 2.0 on Xubuntu 7.10:

  1. Download mono and libgdiplus tarballs from
    $ wget
    $ wget
  2. Install libglib2 development headers:
    $ sudo apt-get install libglib2.0-dev
  3. Install libfontconfig1 development headers (without this ./configure emits configure: error: Cairo requires at least one font backend):
    $ sudo apt-get install libfontconfig1-dev
  4. Compile and install libgdiplus. libgdiplus is required for Winforms, if you don’t use Winforms you can skip this step and use ./configure --with-libgdiplus=no when you compile Mono.
    $ tar -xjf libgdiplus-2.0.tar.bz2
    $ cd libgdiplus-2.0
    $ ./configure
    $ make
    $ sudo make install

    The libraries were installed in /usr/local/lib.

  5. Install bison:
    $ sudo apt-get install bison
  6. Compile Mono:
    $ tar -xjf mono-2.0.tar.bz2
    $ cd mono-2.0
    $ ./configure
    $ make
    $ sudo make install

If you want to compile or run GUI applications using GTK bindings instead of WinForms you need to download and compile Gtk#:

  1. First install the following packages to ensure the necessary headers:
    $ sudo apt-get install libpango1.0-dev
    $ sudo apt-get install libatk1.0-dev
    $ sudo apt-get install libgtk2.0-dev
  2. Download Gtk# source tarball from
  3. Extract, compile and install Gtk#:
    $ tar -zxf gtk-sharp-2.12.0.tar.gz
    $ cd cd gtk-sharp-2.12.0
    $ ./configure
    $ make
    $ sudo make install

Other dependencies
One last point, the following packages were already installed on my machine: fontconfig, fontconfig-config, libfontconfig1 — not sure if they are ‘libgdiplus‘ compilation dependents but if you have problems these may be what are required. My machine already had a number of development tools and utilities installed, so there may be other dependencies I’ve missed for an “out of the box” Xubuntu install.

Getting Started

You need to tell Mono where to find it’s libraries:

$ export LD_LIBRARY_PATH=/usr/local/lib


Next compile and run the Hello Worlds as described in Mono Basics.

If you have problems turn on debugging by setting MONO_LOG_LEVEL the environment variable. For example:

$ MONO_LOG_LEVEL=debug mono hello.exe

Closing thoughts

I like the idea of WinForms as a way of writing desktop apps that run on both Windows and Linux and I like to use Linux for development, problem at the moment is that there’s no SharpDevelop-like IDE for creating WinForm UIs on Linux (MonoDevelop uses GTK). There is a WinForms Designer that runs under Linux but it’s not a full IDE and currently is more a “proof of concept” thing.
