    Continuous Integration packages

    Edit page on GitHub

    The Mono Project hosts a public Jenkins instance, which attempts to compile distribution packages for major GNU/Linux distributions for every commit made to the public Mono git repository on GitHub.

    Requirements

    We are building our packages twice, in the most cross-release-compatible way we can manage.

    For Debian-derived distributions (any distribution which uses .deb files), you need the GNU C library 2.13 or above, and an x86-64 or x86 processor - this should cover Debian 7+, Ubuntu 11.04+, Mint 11+, Elementary 0.2+, and a huge number of other distributions.

    For Red Hat-derived distributions (any distribution which uses .rpm files), you need the GNU C library 2.17 or above, and an x86-64 processor - this should cover CentOS 7+, Mageia 3+, Fedora 19+, openSUSE 12.3+, and a huge number of other distributions.

    Installation

    Regardless of your distribution, you will need the Mono Project GPG signing key, which package managers require.

    Debian, Ubuntu, and derivatives

    Add the Mono Project GPG signing key and the package repository (if you don’t use sudo, be sure to switch to root):

    sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 3FA7E0328081BFF6A14DA29AA6A19B38D3D831EF
echo "deb http://jenkins.mono-project.com/repo/debian sid main" | sudo tee /etc/apt/sources.list.d/mono-jenkins.list
sudo apt-get update

    Run a package upgrade to upgrade existing packages to the latest available. Then install Mono as described in the Usage section.

    CentOS, Fedora, and derivatives

    Add the Mono Project GPG signing key and the package repository in a root shell with:

    rpm --import "http://keyserver.ubuntu.com/pks/lookup?op=get&search=0x3FA7E0328081BFF6A14DA29AA6A19B38D3D831EF"
yum-config-manager --add-repo http://jenkins.mono-project.com/repo/centos/

    Run a package upgrade to upgrade existing packages to the latest available. Then install Mono as described in the Usage section.

    Usage

    Search your package manager for mono-snapshot to find a number of possible packages to install:

    [directhex@centossy ~]$ yum search mono-snapshot

mono-snapshot-20140807112602.x86_64 : Mono runtime snapshot - runtime (git commit 76c34a1)

mono-snapshot-common.noarch : Common helper tools for Mono snapshot packages
mono-snapshot-latest.noarch : Mono runtime snapshot - latest version metapackage

  Name and summary matches only, use "search all" for everything.

    Install the mono-snapshot-XXXXXXXXX package for a specific version, or mono-snapshot-latest to install whatever the latest available version is. With mono-snapshot-latest, your package manager will keep updating you to the latest available version whenever it runs.

    Whenever you install any snapshot package, the mono-snapshot utility will be installed alongside it. Run mono-snapshot to see which snapshot packages are available and installed:

    [directhex@centossy ~]$ mono-snapshot
This script will help you to set up your environment to use a
snapshot package of Mono. To use it, run:

    . mono-snapshot APP/VER

You have the following possible combinations of APP/VER:

    mono/20140807112602
    mono/20140807155904

Calling APP without specifying VER will load the latest version

    You can then configure your environment to use the desired version by calling . mono-snapshot APP/VER - for example, . mono-snapshot mono/20140807112602 (or simply . mono-snapshot mono). Please note the leading “.”:

    [directhex@centossy ~]$ . mono-snapshot mono
[mono-20140807155904][directhex@centossy ~]$ mono --version
