    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 x86-64 processors only at this point in time.

    For Debian-derived distributions (any distribution which uses .deb files), you need the GNU C library 2.13 or above - 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 - 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 public Jenkins GPG signing key, which package managers require:

    http://jenkins.mono-project.com/repo/xamarin.gpg

    Debian, Ubuntu, and derivatives

    Add the GPG key in a root shell with:

    apt-key add xamarin.gpg

    Next, add the package repository in a root shell:

    echo "deb http://jenkins.mono-project.com/repo/debian sid main" > /etc/apt/sources.list.d/mono-jenkins.list

    Update your package cache if necessary.

    CentOS, Fedora, and derivatives

    Add the GPG key in a root shell with:

    rpm --import xamarin.gpg

    Next, add the package repository in a root shell:

    yum-config-manager --add-repo http://jenkins.mono-project.com/repo/centos/

    Update your package cache if necessary.

    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-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
