Preparing for installation on Ubuntu

Python is installed by default on Ubuntu and most other distributions. Some Python packages that are going to be installed for use by Reahl include source code written in C, and are compiled as part of the installation. You need to install all the right tools to make that possible.

It may very well be that these packages are already installed on your system – but we have to make sure. If you’re not on a Debian-based distro, you will have to find and install equivalents for your platform. (Chances are they are called exactly the same.)

Python and basic development tools

Python, a compiler and the basic python development tools are installed by issuing:

sudo apt-get install python3-dev gcc cython python-virtualenv


For Python 2, just install python-dev (or python2.7-dev) instead of python3-dev above.

Additional necessary packages for a Reahl installation

The extra stuff needed by dependencies of Reahl itself are installed by issuing:

sudo apt-get install libxml2-dev libxslt-dev libsqlite3-0

The first two of these packages (libxml2-dev and libxslt-dev) are used by some of our testing infrastructure, and sqlite is the database used by the tutorial examples.

Remember to go back and install Reahl itself in a virtualenv!
