Installing optional requirements

ImageMagick is a software suite to create, edit, compose, or convert bitmap images. It can read and write a variety of formats and be used from within third-party applications, such as Redmine, to perform various tasks on the images uploaded or generated by users.

To install ImageMagick on Ubuntu, simply type the following:

sudo apt-get install ImageMagick libmagickwand-dev

It will download and install a significant number of libraries that are required by ImageMagick.

If you have already installed Redmine and want to add the rmagick gem after installation, use the following command. It can be used for a fresh install as well:

bundle install --with rmagick --without development test postgresql

Redmine uses several SCM binaries so that it can track code-issue relation in most of the popular Source Control Management (SCM) scenarios. Don't confuse this with Software Configuration Management.

On Ubuntu, installing all supported SCM binaries is extremely simple. Just open up a terminal and type the following:

sudo apt-get install subversion darcs mercurial cvs bzr git

After installation, restart your Redmine and navigate to Administration | Settings | Repositories.

You should get a screen that looks similar to this:

The green check sign and version number indicates that the repository client binary is installed and usable.
