LINUX AIR COMBAT is a free, open-source combat flight simulator developed by AskMisterWizard.com for the LINUX community. Its roots came from the well-known "classic" flight game known as "GL-117", but this new incarnation has been extensively re-written and improved.
LINUX AIR COMBAT is also known as "LAC".
Running Linux Air Combat requires desktop Linux supporting all of the usual and customary OpenGL and SDL run-time libraries. Specifically, like most desktop LINUX systems, yours should have all of these:
If your LINUX system is typical, you will need to compile LINUX AIR COMBAT from the free source code (the well-organized source code makes this very easy, even for non-programmers). In addition to the prerequisites listed above, you will also need gcc (almost always present), and all of these tools and libraries, which are generally NOT preinstalled in most major LINUX desktop distributions:
Experienced LINUX users will recognize all of these as well-known LINUX components. For most of the popular LINUX desktop distributions, every one of these components will be freely available through the usual and customary means, using free package managers. If you have a good Internet connection, you should be able to get everything within 5 or 10 minutes and with just a few mouse clicks.
