Unix: Building, Installing and Running Software

Prerequisites

This course is part of the Scientific Computing series.

It is common for a student or researcher to find a piece of software or to have one thrust upon them by a supervisor which they must then build, install and use. It is a myth that any of this requires system privilege. This course demonstrates the building, installation and use of typical software ranging from trivially easy examples (the "configure, make, install" scheme) through to the evils of badly written Makefiles. Common errors and what they mean will be covered and by the end of the course the student should be able to manage their own software without needing to pester their system administrator.

• Those attending should be able to use a plain text editor (e.g. emacs, gedit, vi) on a Unix system as might be obtained from the Emacs or Vi introductory courses.
• A basic knowledge of the Unix command line as might be gleaned from the "Introduction to Unix" course is also required.
