Installing Amber on Ubuntu

You will find below generic recommendations for installing Amber22 as well as specific instructions tailored for your Ubuntu Linux version.

Generic installation instructions

About cmake:

Since Amber20, a new installation mechanism is provided that makes use of cmake. A decent version of cmake is needed, therefore it is highly recommended to download and install the cmake executable from the cmake.org website.

About Python:

Many programs within Amber requires a decent version of Python. When configuring Amber, the run_cmake script will check your installation and will most probably recommend to download and install a compatible Python from Continuum IO (via miniconda). It is highly recommended to follow this suggestion and let the run_cmake script install Python inside the Amber tree.

Building with cmake
